Tsubaki also offers lubefreedrive chains that deliver long-lasting service without lubrication.)Overload may cause roller chain to break. (Avoid breakage by properly selectingproducts with consideration to inertia, etc. Tsubaki offers heavy-duty drive chains inidentical sizes that deliver the high strength of larger chains.)Roller chains can break due to corrosion and other environmental conditions. (Avoidbreakage superior by preventing exposure to corrosive liquids, atmospheres, etc.Tsubaki offers corrosion-resistant drive chains.)Correctly install roller chain to avoid misalignment or uneven wear and possible breakage.7

T S U B A K I D R I V E C H A I NGeneral Comparison of Transmission ElementsThe following table compares roller chains to other power transmission mechanisms such astoothed belts, V-belts and gears. Generally speaking, roller chains are often used aseconomical power transmission suited to low speed and high loads. However, it is alsopossible to use chain in high-speed applications such as camshaft drives for automobiles.TransmissionMechanismSynchronicityTransmissionEfficiencyAnti-shockNoise & VibrationAmbient ConditionsSpaceWeightHigh speed,light loadLow speed,heavy loadLubricationLayout FreedomExcess Loadon ShaftRoller Chain Avoid water and dust.(Corrosion-resistantdrive chains available.)Compact,lightweightAvoid heat, oil,water and dust.Avoid heat, oil,water and dust.

Measures for adjusting chain slack need to be considered.Chain is weak when subjected to loads from the side. It needs proper alignment.Avoid waterand dust.Needs high strengthdue to low numberof engaging teeth.RequiredBefore Use For Safe Use Standard Roller Chains Lube-Free Roller Chains Heavy Duty Roller Chains Corrosion Resistant Roller Chains Specialty Roller Chains Accessories Selection Handling8

ANSI Standard Minimum Tensile Strength (Tensile Breakage Strength)2. Tsubaki Average Tensile Strength3. Tsubaki Minimum Tensile Strength4.Maximum Allowable LoadThis is the minimum tensile strength determined by ANSI Standard. If a roller chain breaksfrom a tensile load below this value, then it is non-compliant. In the case of multi-strand rollerchain, the single strand value is multiplied by the number of strands. (ANSI B 29.100)This is a fracture load reading obtained after a long period of actual tensile strength testing ofa large number of chain strands. Naturally, a roller chain may actually break at a higher orlower value than this, so it does not represent a guaranteed value. This value variesdepending on the manufacturer.This is a minimum value determined bystatistical processing at Tsubaki. If anyroller chain fractures by a tensile loadbelow this value, then it is noncompliant.This value varies dependingon the manufacturer.Testing MethodAs shown in Fig. 2, roller chain with over five links is fixed at both ends by clevises and isstretched until breakage occurs (JIS B 1801-2009). The type of fracture is indicated bybreakage of the roller chain or failure of its parts (Fig. 3.)Fig. 2 Tensile strength testThe maximum allowable load of roller chain (excluding Stainless Steel Chain and EngineeringPlastic Chain*) is the value derived from the lowest fatigue limit. When a load lower than thisvalue is repetitively applied to the roller chain, fatigue failure will never occur.According to the former JIS B 1801-1997, the maximum allowable load indicates abreakage load of Pmax = (Pm + Pa) = 2.2Pa at a frequency of 5 10 6 , when a newroller chain with over five links receives a repetitive load in linear operation. (Fig. 4)Tsubaki standards and catalog values are for 10 7 repetitions, or 2Pa. In other words, ifTsubaki’s maximum allowable load is indicated as maximum load (Pmax), then values in thiscatalog would increase 10%.Fig. 4 Summary chart of repetitive loadLoadFig. 1 Relationship between three tensile strengthsJIS minimum tensile strengthTsubaki minimum tensile strengthFrequencyFig. 3 Shape of fractureAverage tensile strengthTensile strength* Stainless steel and engineered plastic chains:Maximum allowable load is determined from specifying the surfacepressure between pins and bushes based on wear performance.Note that strength of offset links may belower than the chain itself.(Refer to each product page for details.)Time9

Elastic Elongation of Chain under LoadRS Roller Chain, SUPER Roller Chain, Heavy Duty Chain, and Low Noise Drive Chainkilowatt ratings tables show kW values for 15,000 hours of operation using a two-shaft driveand 100 pitches of roller chain under conditions 1 - 5 below.The kW ratings table of Lambda Chain is based on conditions 1 - 4 and shows kW ratingvalues when Lambda Chain is used with two shafts. Lambda Chain has more than seventimes the wear elongation of Standard RS Roller Chain operated without lubrication (#120 and#140 are over 2.5 times). X-LAMBDA has more than five times the wear elongation life ofLambda Roller Chain.1) The chains are operated under ordinary conditions where the ambient temperature is -10 - +60(+14F - +140F) and there is no abrasive dust.2) There are no negative effects from corrosive gasses or high humidity.3) The two shafts are level and the chains are properly installed. (See item 4 on pg. 162.)4) There is minimal fluctuation in load during transmission.5) The recommended lubrication system and lubricant shown in the kW ratings tables is used for RS RollerChain and SUPER Roller Chain. (See pgs. 160 - 161.)Moment of inertia is used to show the degree of inertia in rotational movement; in other words,"rotation difficulty", or "rotation ease." This is equivalent to the mass (weight) of the objectbeing used for straight-line transmission.Moment of inertia is shown in the SI units table as:I = mk 2 (kgm 2 m: mass of rotating body k: turning radius)It is shown in the Gravimetric units table as:J = GK 2(kgfms 2 G: mass of rotating body G: gravitational acceleration).GAlthough, GD 2 = 4GJ (D: diameter of rotating body) is generally being used now in place ofmoment of inertia.Length test method and length tolerance are specified in JIS B 1801-2009. The lengthtolerance of any individual size when subjected to a measured load (e.g. 500 N [50.99 kgf] forRS 80) specified in JIS is 0 to +0.15% of the reference length. The reference length iscalculated by multiplying the reference pitch (P) by the number of links. (Applicable toproducts bearing a JIS identification number.)An elastic elongation curve of a chain under load looks as shown below. Values shown hereare the standard references for single-strand RS Roller Chains. Actual values may slightlydiffer.

Basic Structure (Photo: RS Roller Chain)Offset pinBasic Three DimensionsThe pitch, roller diameter, andinner width of the inner linkare considered the basic threedimensions of a roller chain.When these dimensions areidentical, a roller chain andsprocket are dimensionallycompatible.Cotter pinSpring clips, cotter pins andspring pins are essential partsthat prevent connecting platesfrom falling off, maintainingthe strength of the chain itself.Always install these parts.*Slip FitWhen the shafts and holes arefitted together, there is acontinuous loose fit. This is afit where the range of tolerancefor the hole is larger than therange of tolerance for the shaft(pin or bush).*Press FitWhen the shafts and holes arefitted together, there is acontinuous interferential fit. Thisis a fit where the range oftolerance for the hole is smallerthan the range of tolerance forthe shaft (pin or bush).Slip fitPlateOuter linkRollerdiameterOffset linkInner linkPitchConnecting linkChainWidth between inner link platesThe plate bears the tension placed on the chain. Usually this is a repetitive load, butsometimes it is accompanied by shock. Therefore, the plate must have not only great statictensile strength, but also must hold up to the dynamic forces of load and shock.PinPress fitPress fit*2Press fitSlip fit*1The pin is subject to shearing and bending forces transmitted by the plate. At the same time, itforms a load-bearing part, together with the bush, when the chain flexes during sprocketengagement. Therefore, the pin needs high tensile and shear strength, resistance to bending,and sufficient endurance against shock and wear.BushPinRollerBushConnecting link plateSpring clipInner linkInner plateOuter plateMiddle plateSingle-strandouter linkMulti-strand outer link(Double-strand shown here)chainThe bush is subject to complex forces from all parts, especially from the repetition of shockloads when the chain engages the sprocket. Therefore, the bush needs extremely high shockresistance. In addition, the bush forms a load-bearing part together with the pin, and as suchrequires great wear resistance.RollerThe roller is subject to impact load as it strikes the sprocket teeth during chain engagementwith the sprocket. After engagement, the roller changes its point of contact and balance. It isheld between the sprocket teeth and bush, and moves on the tooth face while receiving acompression load. Therefore, it must be resistant to wear and still have strength againstshock, fatigue and compression. RS11 / 15 / 25 / 35 do not have rollers.Roller LinkTwo bushes are press fit into two inner plates, and rollers are inserted to allow rotation aroundthe outside of the bush. This is the same for single-strand and multi-strand chain.Outer Link and Middle PlateThe pin link consists of two pins that have been press fit into two outer plates. With multistrandroller chain, a middle plate is added to the pin link. The middle plate is slip fit forStandard RS Roller Chain and press fit for SUPER Roller Chain.11

Before Use For Safe UseStandard Roller Chains Lube-Free Roller Chains Heavy Duty Roller Chains Corrosion Resistant Roller Chains Specialty Roller Chains Accessories Selection HandlingFor Safe UseWARNING Obey the following points in order to prevent hazardous situations.Do not use chains and accessories (accessories and parts) for anything other than their original purpose.Never perform additional processing on the chain.. Do not anneal the various parts of the chain.. Do not clean the chain with either acid or alkali, as they may cause cracking.. Do not electroplate the chain or its parts, as it may cause cracking due to hydrogen embrittlement.. Do not weld the chain, as the heat may cause cracking or a reduction in strength.. When heating or cutting the chain with a torch, remove the links immediately adjacent and do not use them again.When there is need to replace a lost or damaged portion of a chain, always replace the whole chain witha new product rather than replacing only the lost or damaged portion.When using a chain on suspension equipment, establish a safety perimeter and strictly prevent entry tothe area directly below the suspended object.Always employ hazard protection devices for the chain and sprocket (safety cover, etc.).If a substance that can cause embrittlement cracking (acid, strong alkali, battery fluid, etc.) adheres to thechain, stop using the chain immediately and replace it with a new one.During installation, removal, maintenance inspection and lubrication of the chain:. Perform the operation according to the instruction manual or this catalog.. Always turn off the power switch to the device and make sure that it cannot be turned on accidentally.. Anchor the chain and parts so that they cannot move freely.. Perform cutting and connecting procedures properly using a press or other special tool.. Wear clothing and employ protective devices that are appropriate to the job (safety glasses, gloves, safety shoes, etc.).. Only allow experienced personnel to perform chain replacement procedures.A fail safe back up system is suggested whenever using Leaf Chain to safely support the load in the eventof a chain failure.CAUTIONObey the following points in order to prevent accidents.Only handle the chain after thoroughly understanding its structure and specifications.When installing a chain, inspect it in advance to confirm that it has not been damaged in transport.Be sure to perform regular maintenance inspections on the chain and sprocket.Chain strength varies according to manufacturer. When selecting a chain based on a Tsubaki catalog,always use the corresponding Tsubaki product.Minimum tensile strength refers to the failure point when the corresponding load is applied to the chain onceand does not refer to the allowable operational load.Warranty1.

T S U B A K I D R I V E C H A I N4. Matched and tagged chainDeviations in chain length exist due to the manufacturingtolerances of the parts. When chains are to be used in paralleland minimizing the relative difference in the lengths is necessary,request a "matched and tagged" chain.Note: A separate charge is required for a length matching.5. Long length formation6. Reel chainSingle-strand RS25 to RS80 chain (see table below) is available on long-length reels.7. Replacement precautionsWhen you do not know the roller chain numberFor example, if you need three sets of two single-strand,120-link RS80 chains, the entry should be:When a chain s total length exceeds 3.048m (10ft), it is called a long length formation. Please consult a Tsubaki representativefor information regarding chains exceeding the lengths below. A separate super long length formation fee and wooden box feeapplies.Example orderOrdering one reel of RS50-1-RP Roller ChainProduct codeChainnumberCount UnitsA110089 RS50-1-RP-10UR 1 RProduct codeA110083A110084A110085A110086A110087A110088A110089A110090A110091Chain number Units per reel Number of links (unit: L)Number of accessory CL(M-type connecting links)RS25-1-RP-150UR 15023999 150RS35-1-RP-20UR 206399 20RS37-1-RP-20UR 20479920RS38-1-RP-20UR 20479920RS41-1-RP-20UR 20479920RS40-1-RP-15UR 15359915RS50-1-RP-10UR 10191910RS60-1-RP-10UR 10159910RS80-1-RP-5UR 559951 2 3Verification of theroller chain specifications(strength type, material, etc.)is important.

Wet environments can cause the oil in the oil-impregnated bush to leak. Bushes are also coated with lessrust-preventing oil, causing early rusting.Bush oil can leak in a vacuum, decreasing wear resistance. Do not use in a vacuum.The life of the chain will decrease dramatically if oil in oil-impregnated bush is depleted. (See "(9) Lambda Chain Life" on pg. 168.)KW ratings for double-strand Lambda Chain (Double-strand coefficient)The coefficient of a double-strand chain with the same part dimensions of a single-strand chain is 1.4. To achieve the same coefficient ofmulti-strand RS Roller Chain, the outer and inner plates must be thickened, and an H class FCL (press fit) must be used. In any event,sprockets must be customized - double-strand RS-type sprockets cannot be used.Double-strand Lambda Chain pin lengthBecause the inner plate is thicker than that of an RS Roller Chain, the pin is longer by an equal amount (L1 and L").

Corrosion Resistant Roller ChainsStainless Steel Roller ChainsThese roller chains are made of stainless steel.SS SpecificationThese roller chains are made of 304 stainless steel (301 stainless steel clips). They offer greatercorrosion resistance than RS Roller Chains and RS Surface Treated Roller Chains, and can be usedin water and in corrosive atmospheres that are acidic or alkaline, as well as in low or hightemperatures (-20 to 400ßC). 304 stainless steel is only marginally magnetic. Some magnetismexists only due to the cold-forging process.NS SpecificationThese roller chains are made of 316 stainless steel (301 stainless steel clips on RS25NS, and 304stainless steel cotter pins on RS80NS). They are suited for applications that require higher corrosionresistance than SS chains. Except for the clips, they are non-magnetic.AS SpecificationThe pins and rollers of these roller chains are made of precipitation-hardened, tempered stainlesssteel, while the plates and bushes are 18-8SUS (304 stainless steel clips are 17-7SUS (301stainless steel)). They have a maximum allowable load that is 1.5 times that of SS chains. Corrosionresistance is slightly less than that of SS chains. AS chains are suited for applications that requirecorrosion resistance, heat resistance, and smaller sizes / higher kilowatt ratings than SS chains.Because of its precipitation-hardened stainless steel, the chains are magnetic.Surface Treated Roller ChainsThese are surface-treated RS Roller Chains.NP SpecificationThese chains are RS Roller Chains with nickel plating. The nickel plating not only improvesappearance, but also adds a small degree of corrosion resistance. Therefore, they can be used inapplications where there is exposure to water. Bear in mind when making your selection thatmaximum allowable load is approx. 15% lower than with RS Roller Chains.NEP SpecificationNEP Chain is a Coating chain with a high corrosion resistance thanks to its zinc coating base andtwo different kinds of special surface coatings for rollers and other parts. The zinc coating andspecial surface coatings protect the chain body from corrosive environments, giving it superior rustprevention. NEP Chain has superior anti-rust capabilities over previous WP or DP chains, reducingits load on the environment.APP SpecificationPins are treated with a non-strength degrading surface treatment to protect against pitting corrosionthat leads to fatigue breakage, making it highly effective in environments that readily promotecorrosion, such as outdoor or coastal applications. Safety precautions when using Surface Treated Drive ChainsDo not use NP / NEP specification Surface Treated Drive Chains if the chains will come in direct contact with food or where coatingflakes or wear dust can contaminate food. The specific gravity of flaked NEP film is lighter than water and will float.Also, in non-food applications, either appropriately cover the chains or contact Tsubaki about chain selection if usage is planned inenvironments where coating flakes and wear dust present problems. Though nickel is not subject to the Food Sanitation Law or theIndustrial Safety and Health Law, plating on sliding parts can flake.SSNSASNPNEPBefore Use For Safe Use Standard Roller Chains Lube-Free Roller Chains Heavy Duty Roller Chains Corrosion Resistant Roller Chains Specialty Roller Chains Accessories Selection Handling98

For details on corrosion resistance selection, see pg. 157. Thesechains can be used in temperatures of —20 to 400ßC.Poly Steel ChainsPC (Standard Specification)The pins and outer plates of these chains are made of 304 stainless steel (301 stainless steel clips),while the inner plates are of engineered plastic (white). They are lube-free, low noise (5 dB less thanRS Roller Chains) and lightweight (50% of RS Roller Chains). They can be used in temperatures of—10 to 80ßC. For details on corrosion resistance selection, see pg. 157.PC-SY (Super Chemical Resistance Specification)The pins and outer plates of these chains are made of titanium, while the inner plates are of aspecial engineered plastic (matte white); therefore they are suited for applications in which PCChains have insufficient corrosion resistance. They can be used in temperatures of —10 to 80ßC. Fordetails on corrosion resistance selection, see pg. 157. Bear in mind when making your selection thatmaximum allowable load is about 60% that of PC Chains.BS-PC (BS Standard Specifications)Poly Steel Chain that conforms to BS standards.Curved Stainless Steel Roller ChainsThese roller chains have a wide sideflex due to its original pin / bush construction and the largeclearance between its plates. Curved transmission is easy using RS-type standard sprockets.Low Noise Roller ChainsThese chains emit 6 to 8 dB less noise than pre-lubed RS Roller Chains (in-house comparisontesting). They can be used in temperatures of —10 to 60ßC.Cold Resistant Roller ChainsSN Low NoiseThese chains can be used in lower temperatures than RS Roller Chains yet deliver the same allowable load (when using an F-typeconnecting link). Expect a 20% reduction in strength when using an M-type connecting link. They can be used in temperatures of —40 to 60ßC. Pre-Delivery LubricationPCCurved Stainless Pre-delivery lubrication is not carried out on SS Specification or NS Specification Stainless Steel Roller Chain, Titanium RollerChains, or Curved Stainless Steel Roller Chains. If these chains are to be used in environments where they are not submergedin or come in contact with water, pre-use lubrication of the chain must take place. If chains are used in these conditions without lubrication, poor articulation of the chain may occur at a much earlier stage than expected.The maximum allowable load is calculated when chain is lubricated (including water lubricant).*RS11-SS-1 chain is lubricated.99

Corrosion Resistant Roller Chains Surface-Treated Drive ChainsAPP SpecificationOutstanding performance in atmospheres conducive to pitting corrosionOpposite side of worn surfaceInitiation pointWorn surfacePins are treated with a special surface treatment toprotect against pitting corrosion that leads to fatiguebreaks, thus preventing strength loss. This treatmentis highly effective in environments that readily promotecorrosion, such as outdoors or coastal applications.Note: Pitting is a type of localized corrosion affecting metal surfaces. Pits form toward the interior, and if pitting occurs on pin surfaces, that pin can quickly leadto fatigue breakage and chain failure.Features No strength loss! Eco-friendly chrome-free!Same as standard steel chain.Example applicationsSpecial surface treatment does not use hazardoushexavalent chrome.APP Chains are ideal for atmospheres that readily promote corrosion.Outdoor uses Coastal or riverside uses When regular lubrication is difficultBucket elevatorsTransfer cranes and other port machineryExamples of fatigue breaks caused by pitting corrosionChain: RS240Applicable modelsChain numberBecause equipment is used outdoors,rain can infiltrate gaps in covers, creatingconditions that promote pitting corrosion.Equipment: Port container carrierPitting readily occurs in equipmentexposed to salty air or saltwater spray.Pitting corrosion of the pin due to insufficient lubrication (effects of salty air and saltwater) and corrosive atmosphere - - Fatigue breakageEnlarged viewof fracture surfaceSingle/Double Strand RS Roller ChainPin breakagePitting corrosion readilyoccurs on the opposite sideof the bush wear surface.Enlarged viewof breakageStarting pointPitting was observed inmore than one location.Single Strand Heavy Duty Roller ChainExcept for the surface-treated pins, dimensions and other specifications are the same as other roller chains.Secondary fracture in link plateLoad can become imbalancedafter pin breakage, leading tosecondary breaks in plates.(For other models, contact Tsubaki.)Before Use For Safe Use Standard Roller Chains Lube-Free Roller Chains Heavy Duty Roller Chains Corrosion Resistant Roller Chains Specialty Roller Chains Accessories Selection HandlingNote: Select connectinglink (CL).Anti-Pitting Roller Chain106

Corrosion Resistant Roller ChainsLow Noise Roller ChainsTsubaki’s uniquely structured spring rollers are used for the chain rollers. When Tsubaki’s Low Noise RollerChain engages the sprocket, the spring roller deforms and absorbs the force of impact, reducing impactnoise between chain and sprocket for lower noise levels. Compared with Tsubaki’s standard RS Roller Chain(pre-lubricated), noise levels of Low Noise Roller Chain are 6 - 8 dB lower. (In-house comparison testing)Benefits of noise reductionNoise level dB (A)Less factory noise for a better work environment.A low noise function is added to machinery and equipment used for manufacturing, and contributes to upgrading and improving their overall image.Belts were considered as a countermeasure for noise; however, there are many limitations in terms of application, strength and overall cost. LowNoise Chain is the perfect countermeasure.Recommended for applications where silence is a major concern, such as stage lifts used in theaters.85807570656050SprocketImpact noiseFeaturesLow noise50InterchangeabilityRollerStandard RS Roller Chain100 150Chain speed (m/min)Dimensional specifications are the same as for RS Roller Chain.Note: There are limits on drive power; check kW ratings tables on pgs. 109—111.SelectionUse the General Selection Method (the kilowatt ratings tables on pgs. 109—111).See selection pages for more details.Operating temperatures—10¡C to 60¡CAllowable chain speed200 m / min (max.)SprocketCan be used with standard RS sprockets.If the chain cannot be sufficiently lubricated, choosesprockets with hardered tooth tip specifications.For less noiseNoise levels reduced by 6 dB to 8 dB compared with the RS Roller Chain.In-house comparison of noise levelsRS50-1(RS Roller Chain)RS50-SNS-1(Low Noise Roller Chain)SprocketTest conditionsChain tension: 3.29 kNLubrication: Pre-lubrication onlymeasurement position: 300 mmfrom drive sprocketTest chainsRS50-SNS-1(Low Noise Roller Chain)RS50-1(RS Roller Chain)Spring roller (deforms)Lessens impact noiseLow Noise Roller ChainSpeed reducer w / motorDrivesprocketMeasurementdeviceBefore Use For Safe Use Standard Roller Chains Lube-Free Roller Chains Heavy Duty Roller Chains Corrosion Resistant Roller Chains Specialty Roller Chains Accessories Selection Handling108

Leaf ChainsConstructionLeaf chains are also commonly called balance chains. The mostbasic type of steel chain, they consist of just plates and pins.Conforming to JIS specifications and suitable for use in low-speedequipment, leaf chains are mainly used for lifting, counterweights,and motion drives.The plates are connected by pins and take the strain when load isapplied. Pins are press fitted to outer plates and riveted. However,a slip fit* is used with middle and inner plates and pins.The pins pass between the plates and have to withstand the bulk ofthe shear forces resulting when the chain is under tension andmove freely within the inner plate holes when the chain articulates.* Slip fitWhen a pin is fitted to a hole, some play is normally allowed. The tolerancerange of the hole diameter is larger than the tolerance range for the pin diameter.* Press fitWhen a pin is fitted to a hole, the pin is normally tight against the hole. Thetolerance range of the hole diameter is less than the tolerance range for the pindiameter.TypesAL Type External plate dimensions and thickness arethe same as for the outer plates of RS Roller Chain withthe same pitch, while the pin diameter is almost thesame.End linksMiddle plateConnecting plate (slip fit)Inner plate and pin (slip fit)Inner linkOuter plate and pin (press fit)Middle plate and pin (slip fit)Outer linkThere are two types of leaf chain: AL for light loads and BL for heavy loads.

Use heat-treated HRC (35 to 40) for high repetition applications.Precautions for UseLubricate regularly to prevent pin rotationand improve wear life.Recommended lubrication: ISO VG 100 to 150 (SAE30 to SAE40)Lubrication method: With the chain loose, use a brush or oil stick tosufficiently lubricate the outer chain, making surethat oil also penetrates between plates.Lubrication period: Lubricate regularly so that sliding sections betweenpins and inner plates do not dry out.Avoid use in corrosive environments.Wipe immediately when there is contact with water andlubricate well. When there is a possibility of corrosion,apply a large amount of grease to the surface of thechain. (To lubricate, wipe off grease and reapply afterlubricating between plates.)Check for elongation.Replace chain when elongation reaches allowableelongation limit (3%).Guidelines for checking chain elongationIn order to prevent chain backlash, measure with slight tension on the chain.Use calipers to measure the distance between the outside L1 and inside L2 of the pins forthe portion of the chain articulating around the sheave as shown in the illustration to obtain Obtain chain elongation percentage using the following formula. - Standard lengthChain elongation =100(%)Standard lengthStandard length = Chain pitch x No. of linksNote: Pitch elongation limit can be quickly checked with achain elongation scale.

Specialty Roller ChainsPin Gear Attachment ChainBefore Use For Safe UseStandard Roller Chains Lube-Free Roller Chains Heavy Duty Roller Chains Corrosion Resistant Roller Chains Specialty Roller Chains Accessories Selection HandlingFor straight drive and large-radius turning operations, a chain gear is used by the drivesource (motor, etc.) through a reducer. This can result in cost issues and so on, as thechain requires a great deal of space, and precision processing is required for the gears.Pin Gears are perfect in this situation.An Attachment Chain is used around the outside of the drum in place of a gear drivewheel, and a specially-processed sprocket is used for the pinion gear. For linear operation,an Attachment Chain is installed horizontally in place of the rack. Be sure to use heattreatedinstallation bolts.

AccessoriesHandling PrecautionsWhen installing the tensioner on a base after attaching the idler sprocket to the tensioner, be sure to fasten the idler sprocket and thetensioner with a bolt. The following table indicates the tightening torque. Be sure to use bolts with a strength classification of 8.8 or more.When setting the tensioner, adjust with a shim so that the center of the idler sprocket and chain are aligned.If the idler sprocket is anchored in place, check whether or not the sprocket can turn smoothly. If it does not turn smoothly, the bolt maybe too tight. Loosen the bolt and then retighten properly.

(Aslotted hole is convenient.)6) Push in on the chain with thetensioner and temporarilytighten the tensioner to thebase with a bolt.

In this case, two boltholes are required, but a hole that is as long as possible willmake positioning simpler, and the re-tensioning operationwill be easier when the chain elongates.3) Temporarily tighten thetensioner with two bolts. Atthis time, adjust with ashim, etc., so that thecenter of the idler sprocketand roller chain are aligned.(Fig. 6)Fig. 5 Tensioner position (front)BaseShimFig. 6 Tightening the tensioner4) Push in on the chain with the tensioner and, if the amount ofslack is appropriate (), tighten the nut and anchor the tensioner.Aim for a value less than = 0.02 x L.

Service FactorsMulti-strand factorThe load borne by multi-strand roller chain is unequalacross the width of the chain, and thus it cannot beexpected that the transmission capacity will be equalto the capacity of a single-strand roller chainmultiplied by the number of strands. For this reason,the transmission capacity of multi-strand roller chainis obtained by multiplying the transmission capacityof single-strand roller chain by a multi-strand factor.Table 1: Multi-strand factorNumber ofroller chain strandsDouble strandTriple strandQuadruple strandQuintiple strandSextuple strandMulti-strand factor1.72.53.33.94.6Service factor KsThe kW ratings are based on conditions of minimalload fluctuation. Depending on the degree of loadfluctuation, it may be necessary to correct thekilowatt ratings using the service factor Ks.Use Table 2 below to determine the appropriate servicefactor based on the type of machine and the sourceof power.The design kW value is obtained by multiplying thekilowatt ratings by the service factor.Table 2: Service factor KsType ofimpactSmoothModerateLargePower sourceExample machinesBelt conveyors with little loadfluctuation, chain conveyors,centrifugal pumps, centrifugalblowers, ordinary textile machines,and ordinary machineswith little load fluctuation.Centrifugal compressors, marineengines, conveyors with moderateload fluctuation, automatic furnaces,dryers, pulverizers, generalmachine tools, compressors,general construction machines,general paper mill machines.Presses, crushers, constructionand mining equipment, vibrationmachines, oil well rigs,rubber mixers, rolls, roll gangs,general machines with reverseor large-impact loads.Motor orTurbineInternal combustion engineWithhydraulic driveWithouthydraulic drive1.0 1.0 1.21.3 1.2 1.41.5 1.4 1.7RPM factor Kn and teeth factor KzTable 3: RPM factor Kn and number of teeth factor KzRPM r/min RPM factor KnLess than 27 1.0027 or more, less than 37 1.0337 or more, less than 50 1.0750 or more, less than 70 1.1070 or more, less than 100 1.14100 or more, less than 150 1.19150 or more, less than 300 1.27300 or more, less than 500 1.34500 or more, less than 1000 1.441000 or more, less than 2000 1.542000 or more, less than 4000 1.65Figure 1: Shock factor KR =Number of teeth Teeth factor Kz9 or more, less than 12 1.1612 or more, less than 15 1.1415 or more, less than 18 1.1218 or more, less than 24 1.1024 or more, less than 30 1.0830 or more, less than 38 1.0638 or more, less than 47 1.0447 or more, less than 60 1.0260 or higher 1.00Shock factor KThis coefficient is determined by the ratio of themoments of inertia between the prime mover and thedriven machine (rate of I, GD 2 ), and the amount ofbacklash in the transmission device.When the inertia ratio R is greater than 10, use R = 10.When the inertia ratio R is less than 0.2, use R = 0.2.If I or GD 2of the prime mover or driven machine isunknown, use the value of R in Figure 1.Shock factor KTransmission Lifting work ConveyorMillHoistRoll gangCrane travel and ShuttleInertia ratio RFlywheelTable 4: Imbalance load factor Kudevice has backlashLoad inertia converted to motor shaft inertiaMotor inertiaTransmission device has no backlash caused by slack in chain,etc.Imbalance load factor KuWhen carrying out shuttle traction and lifting with twochains, or four chains for shuttle drive and lifting, thechain tension is not uniform.

If site restrictions require ashort distance between shafts andthe smallest possible sprocket outerdiameter, use a multi-strand rollerchain with a small pitch.(2) Select number of teeth for largesprocketOnce the number of teeth of the smallsprocket has been decided, the numberof teeth of the large sprocket isdetermined by multiplying the numberof teeth of the small sprocket bythe speed ratio.The number of teeth of the smallsprocket should be at least 15. However,it is not desirable if this causesthe number of teeth of the largesprocket to exceed 120. In this event,the number of teeth of the smallsprocket must be reduced; however,it is recommended to use more than13 teeth.Step 7When the number of links is oddIf the number of links is odd, it isbest to avoid using an offset linkand instead change the distancebetween shafts so that the numberof links is even. If the one-pitch offsetlink of RS roller chain or the fourpitchoffset link of SUPER chain isused, allow for a decrease of transmissionpower as explained in thenotes in the kW ratings tables.

Since thespeed ratio is 1/3, the number of teeth will be 17T and 51T ofRS100. But, with an outer diameter of 17T at 189 mm and51T at 534 mm, these are not adequate because they do notfit in the required space. 189 + 534 > 700(2) Checking multi-strand chains:19T and 57T of the RS80-2 is derived for double-strand, andthe outer diameter of its sprockets are 167 mm and 476 mm,which is within limits. Check RS80 kilowatt ratings table forthe kW ratings of 19T of RS80-2.The kW ratings for the small sprocket number of teeth 19T is5.06 kW at 50 r/min, and 9.44 kW at 100 r/min. By calculatingproportionally using the tabular difference between them,drive kW for 90 r/min is 8.56 kW.(3) This 8.56 kW is the kilowatt rating of single-strand chain, andthe kilowatt rating of double-strand chain that will be used isderived from the multi-strand factor in Table 1.8.56 kW X 1.7 = 14.6 kWMotorAgitator(Step 6) Check the bore diameter(1) Check the bore diameter on the dimension table.

The ambient temperature is different from thetemperature of the roller chain itself.Multiply the ambient temperature the chain will be used in by the temperature coefficient in Table 2 below to calculate kilowatt ratings.Calculate the temperature coefficient with the maximum usage temperature of the equipment on which the chain will be installed.Table 2: Temperature Coefficient by Ambient Temperature TemperatureRS40 – RS80Room temperature – 150°C Catalog kW rating 1150°C – 200°C Catalog kW rating 3/4200°C – 230°C Catalog kW rating 1/2Note: A double-strand LMC chain only has the maximum allowable load of asingle-strand LMD chain.Always confirm strength when using for power transmission.11.3 Selection method for Stainless Steel Roller Chain (SS and NS specification) at high temperatures (400 or higher)As the temperature of a chain increases, its strength decreases. The usage limit at high temperatures is determined by thetemperature of the chain itself. Consult Tsubaki when using stainless steel chain at ambient temperatures of 400 or higher.However, chain cannot be used at 700 or higher. When a chain is selected using the temperature selection method, thechain speed must be below the maximum speed of the allowable load selection method.Changes and cautions associated with high temperature environments are:1) All clearances need to be abjusted to prevent poor articulation and poor roller rotation due to thermal expansion.2) The chain may break (creep rupture) under low loads as the temperature increases.12. Special selection method for Corrosion Resistant Roller ChainWhen selecting Corrosion Resistant Chain use the allowable load selection method.1) The maximum allowable tension for Corrosion Resistant Chain is low compared to Standard RS Roller Chain. (Excluding NEP.)2) Avoid using offset links when possible.3) Refer to the following page when acid or alkali solutions or chemicals will come in direct contact with the chain.4) Selection formula:Before Use For Safe Use Standard Roller Chains Lube-Free Roller Chains Heavy Duty Roller Chains Corrosion Resistant Roller Chains Specialty Roller Chains Accessories Selection HandlingMaximum working load applied to the chainServicefactorKsRPMKnNumber of teethfactorKzMaximum allowableload of the chain156

T S U B A K I D R I V E C H A I NHandling Roller Chains and Sprockets1. How to Cut Roller ChainIf the chain you purchased is either a unit length (3,048mm) or on a reel, it is necessary for you to cut the chainto the necessary length.Using a chain vice and punchHow to cut a roller chainUsing a chain breaker1. 1 Using a chain vice and punch1) For riveted type roller chain, grind down one end ofthe outer plate's two pins (same side) to the surfaceof the plate. Be careful of the chain overheatingduring the grinding process.This process is unnecessaryfor Poly Steel Chain as there are no rivets. As RS08B-1to RS16B-1 use easy cutting pins, the rivets do notneed to be ground.2) Remove the cotter pin for cotter pin type roller chain.Grind the rivets of the pins until( they are flush with the plate. )Fig. 1 Rivet-type roller chainFig. 2 Grinding the pin ends3) Place the roller chain into the groove of the chainvise (see Accessories Section) and tighten thevice to secure the roller to be disassembled.Follow 1.3 and 1.4 for Poly Steel Chain andLambda chain.For multi-strand SUPER Roller Chain, place thelowest roller into the groove of the chain vice.Fig. 3 Setting the roller chain in the chain viceSetting SUPER Roller Chain4) Place a primary punch(see Accessories Section),according to chain size, onPrimary punchthe head of the ground pin,and then hit the head ofOuter platethe primary punch with ahammer. Make sure to hitVicethe pins alternatively toensure the pins are removedFig. 4 Tapping the pin withevenly and at the same the primary punchtime. Continue to tap thepin until just before the pin is removed from theouter plate.5) Use a secondary punch (see AccessoriesSection) to remove the pin completely from theouter link plate. Check to make sure that the bushwhere the pin was removed has not come looseor deformed. Do not use if loose or deformed.Safety precautionsMake sure to use a grinder when grinding theriveted portion of one end of the rivet-type pin.If it is extracted without being ground first,more time and effort will be spent, damagingthe chain.Do not reuse any removed parts.1. 2 Using a chain breaker1)2)For riveted type roller chain, grind down one end ofthe outer plate's twopins (same side) to thesurface of the link plate.(Same as 1.1) Removethe cotter pin for cotterpin type roller chain.Remove the two pinsfrom the same outerplate. Check to makesure that the bush whereFig. 5 Hot to cut a chain using a chain screwthe pin was removed has not come loose or deformed.Do not use if loose or deformed.Safety precautionsA chain breaker (see Accessories Section) is atool made for cutting chain, and can cut rollerchain that is set on a machine. In this case, it isnecessary beforehand to support the load onthe roller chain and the weight of the roller chainitself to prevent it from falling after being cut.Do not reuse any removed parts.1. 3 How to cut Poly Steel Chain1)2)Support the outer plate of the chain in the cradleand push down on the pinhead with the exclusivepunch.

Be careful of the chainoverheating during the grinding process. Grindingshould be carried out slowly so as not to overheat thebushes in particular.Then cut the chain using an exclusive cradle (seeAccessories section) and an RS Roller Chain punch.Important points for cutting are outlined in 4) and 5) in1.1. However, use an exclusive cradle instead of a vice.Hit the pins alternatively when removing the pins with apunch. Take extra care not to remove or cause anydamage to the bush. Do not use bush if it has comeloose or been damaged.2. How to Connect Roller Chain2. 1 When connecting chain on sprocket teethWhen connecting or disconnecting roller chain, itis convenient to use the sprocket teeth. Pleasecarry out the following steps.1) Wind the chain around one of the sprockets so that bothends of the chain are facing each other on the sprocket.2) Insert the connecting link in the two end links of the chain.3) Insert the connecting link plate of the connecting link and fastenthe plate using the clips/cotter pins or spring pins provided.4) When using a press-fit connecting link or F-Type (semipress-fit) connecting link, insert the connecting link plateby tapping it with a hammer until it moves into position.Then fasten it usingthe clips/cotter pins orspring pins provided.5) When using the sprocketteeth to connect thechain, take care notto damage the teeth,particularly when usinga cast iron sprocket.Fig. 8 Connecting on a sprocket2. 2 When connecting between shaftsIf a sprocket cannot be used due to layout, followthe procedures below.1) Wind the chain around the sprockets and pull the chainends together using a chain puller (see Accessoriessection) or wire.2) Insert the connectinglink in the two endlinks of the chain.3) Insert the connectinglink plate of theconnecting link andfasten the plate usingthe clips/cotter pins orspring pins provided.Fig. 9 Connecting between shafts2. 3 Clip and Cotter Pins1) ClipClips are used for small size roller chain (underRS60) connecting links. When connecting the chain,the clip should be inserted securely into the slot ofthe pin on the connecting link after the connectingplate has been inserted on the pin. If the legs of theclips are spread too far they will not catch properlyand will fall off during operation of the chain, causingaccidents. Care should be takenwhen inserting them. The clip isgenerally installed opposite tothe direction of travel for thechain as shown in Fig. 10.Direction of travelFig. 10 Direction in whichthe clip is installed2) Cotter PinsTsubaki cotter pins are treated for Standard, Heavy-Duty,and Lambda Chain. The legs of the cotter pin should bebent approx. 60 degrees. Cotter pins should not bereused, and commercially available cotter pins otherthan those produced by Tsubaki should be avoided.Cotter pinFig. 11 Opening range of pinsRS Roller Chain cotter pin dimensions (These pins are not available commercially.)Chain size Nominal cotter pin dimension Chain size Nominal cotter pin dimensionRS35 1 6 RS100 2.520RS40 1 6 RS120 3 23RS50 1.6 8 RS140RS160 4 24.5RS60 2 10 RS180 5 32RS80 2.514 RS200 5 37Note: RS240 uses a roll pin.Safety PrecautionsT-pinZ-pinAvoid using offset links wherever possible byvarying the center distance between shafts orusing an idler.In the case of pins and connecting link plate holesbeing press-fit type with F-Type or other connectinglinks, please avoid widening the connecting linkplate hole or narrowing the pin diameter to makeconnecting easier, as this will result in a reductionin roller chain strength and cause an accident.The outer link of cotter pin type roller chain canbe used as a substitute for the connecting link.However, due to the press fit connection, theouter link plate must be carefully driven ontothe pin parallel to the connecting link. If theconnecting link plate is installed without duecare to parallelism, chain damage or increasedwear may result. Use caution as per (2) above.Donot reuse press fit type link plates that havebeen detached, as the detachment results in areduction in strength.159

Handling of roller chain and sprocket3. Roller Chain LubricationLubrication is very important in roller chain transmission,and becomes especially important when stringentdemands are placed on chain performance.When lubrication is not complete, even the most advancedtransmission device will not realize its full servicelife. Under some conditions the device may wearout within a very short period of time. For this reason,exercise special care with respect to lubrication.1) The main reason for oiling and lubing roller chain is to minimizewear elongation of the chain and prevent corrosion.Wear elongation is caused by wear between the pin andbush in articulating parts.2) Roller chain is coated with oil before being packaged(except for stainless steel chain). This oil is a high grade oilthat prevents rust and provides lubrication. The oil preventsthe wear that frequently occurs in the initial stage ofoperation, and it works well with lubrication oil to maintain ahigh wear resistance.3) Avoid wiping the oil coating off of delivered roller chain, andavoid washing the chain with detergent or other cleaning agents.3.1 Oil application locations1) Roller chain wear occurs from wear between each pin andbush, and thus oil must be applied to these parts.2) On the slack part of the chain, apply lubrication oil to thegap between each outer plate and inner plate. At the sametime, apply oil between the bushes and rollers.3.3 Recommended lubricating oils1) SAE numbers (Table 1)Lubricant typeAABCAmbient temperatureChain number10 Cto0C 0 C to40C 40 C to50C 50 Cto60C 10 C to0C 0 Cto40C 40 Cto50C 50 C to60CRS50 or lower small pitch chain SAE10W SAE20 SAE30 SAE40SAE10W SAE20 SAE30 SAE40RS60 / 80SAE20 SAE30 SAE40RS100SAE50SAE20 SAE30 SAE40 SAE50RS120 or higher large pitch chain SAE30 SAE40 SAE502) Commercially available lubrication (Table 2)SAESAE10WManufacturer name32Exxon MobileCST40General Sekiyu Panorre 32Idemitsu Kosan Dafuni Mechanic Oil 32Japan Energy (JOMO) Retasu 32Shinnihon SekiyuShowa Shell Sekiyu50 Cto25 CSAE2068683.2 Chain used for lifting1) In general the chain has no catenary parts. If possible, removethe load that acts on the roller chain before lubing the chain.2) For roller chain that does not articulate, oil the chain sufficientlyand then apply a thick layer of grease around theroller chain to prevent corrosion.Sufficiently lube end fitting connections, even if these do notmove.3) For roller chain that is used outdoors, contact with rain andsnow will remove the lubrication and cause harmful corrosion,and thus a cover or other protection should be installed.If rain or snow does fall on the chain, remove the moistureand then promptly lube the chain and coat it with a thick layerof grease.SAE30100SAE40150SAE5022068 100 150 2203) Examples of lubrication at low and high temperatures (Table 3)The following oils are available when roller chain is used at low or high temperatures.

A brush canalso be used.Stop operationbefore oiling.Using a simplecase, this methoddrips oil suppliedfrom an oil cup.The chain is runthrough oil in a leakfreecasing.Use a slinger disc attachedto a leak freecase to splash oil on thechain. The peripheral velocityof the disc shouldbe 200 m/min or higher.If the width of the chain isgreater than 125 mm, attachdiscs to both sides.The oil is circulatedin a leak-free caseand cooled by apump. When thereare n strands ofchain, n+1 oilingholes are required,targeting the gapsbetween each part.Oil with sufficient frequency (in generalabout once every 8 hours) so that the rollerchain bearings do not dry out.For one strand of chain, drip about 5 to 20drops of oil each minute. Drip more oil onhigher speed chains.If depth h from the surface of the oil to thelowest point the chain reaches is toodeep, the oil may heat up (80°C or higher)and deteriorate. The depth to which thechain descends in the oil should be about6 to 12 mm.The lowest point h reached by the slingerdisc should be about 12 to 25 mm belowthe surface of the oil. The roller chainshould not enter the oil.Approximate oiling quantity per oiling hole (L/min)NameRSSUPRSSUPRSSUPChain numberChain speed(m/min)500 800Less than 300800 1,100300 5001,100 1,400500 or moreQuantityRS60orsmaller1.02.03.0801001.52.53.51201402.53.54.5#160orlarger4.05.06.0To verify sufficient lubrication is taking place, remove the chain and inspect the connecting pins and bushes.

Handling of roller chain and sprocket4. Layout and Installation of Roller Chain4.1 Speed ratio and chain lapA roller chain transmission speed ratio up to 7:1 is normallysuitable; however, at very slow speeds a ratio upto about 10:1 is possible. The chain lap between thesmall sprocket and chain must be 120° or more. Forlifting applications, the angle must be 90° or more.Fig. 13: Chain lapLifting application4.2 Distance between shaftsThe minimum distance can be as short as desired aslong as the teeth of the two sprockets are not in contact.The optimum center-to-center distance betweenthe shafts is 30 to 50 times the pitch of the roller chain.However, if the load is variable, a distance of 20 timesor less is suitable.4.3 Amount of slack1) Unlike V or flat-belt transmission, there is no need to applyan initial tension in roller chain transmission; rollerchain is normally used with a suitable amount of slack.If too much tension is applied to roller chain, the oil filmbetween the pins and bushes will be broken, causingincreased wear and damage on the roller chain andbearings. If there is too much slack in the roller chain,the chain will vibrate and ride up the sprocket,damaging both chain and sprocket.2)If possible, the lower side should be the slack side in rollerchain transmission. The amount of slack is appropriatewhen the distance (SS') that the chain can be moved perpendicularlyby hand at the center of the slack side is 4% ofthe span (AB). (For example, when the span is 800 mm, theamount of slack should be 800 mm x 0.04 = 32 mm.)In the following situations, this should be 2%:1) When the transmission is vertical or close to vertical(a tensioner is required).2) When the distance between the shafts is morethan 1 m.3) When frequent starts are made with a heavy load.4) When sudden reverse motion takes place.SpanFig. 14: Amount of slack3) Roller chain will stretch slightly during the first few dozenhours of use as the contact surfaces wear in (about0.05%). This may result in too much slack in the rollerchain and may require adjustment of the slack.A tensioner can be used if the layout is designed for it. Ifyou do not have a tensioner, move the shafts to adjustthe amount of slack. Once the chain is worn-in, very littlestretching will occur.4.4 Horizon precision and parallelism of the shaftsThe installation precision of the sprocket has a largeeffect on the smoothness of roller chain transmission.It also affects roller chain life.Install the sprockets correctly as described below.1) Verify Horizontal precision with a level.Adjust the precision to within ±1/300.Level gaugeFig. 15: Horizontal precision2) Use a scale to correct the degree of parallelism ofthe shafts.Adjust the shafts so that they are parallel to within±1/300 = (A-B/L).Before Use For Safe Use Standard Roller Chains Lube-Free Roller Chains Heavy Duty Roller Chains Corrosion Resistant Roller Chains Specialty Roller Chains Accessories Selection HandlingFig. 16: Degree of parallelism of the shafts162

In a layout that is close to vertical, the rollerchain may stretch and fall off the sprocket. Thus, anidler or tensioner should be used. If possible keepthe angle of inclination within 60°.Fig. 18: General layoutFig. 19: Layout when the center-to-center distance is shortIntermediate idlerCatenary side2) Layouts requiring caution(1) When the slack is on the upper sideWhen the center-to-center distance between theshafts is short, move the shafts to adjust the distanceand slightly increase the tension.When the center-to-center distance is long, insertan intermediate idler under the slack part to supportthe roller chain.(2) When the chain speed is fast and the load variesRoller chain may vibrate if the natural vibration frequencyof the chain, shock frequency of the drivenmachine, or chordal action of the chain (verticalpulsation of the chain due to the polygoneffect) synchronize. In this event, use a guideshoe (made of NBR or ultra-high polymer polyethylene)or other device to stop the vibration.Fig. 21: Guide shoe to prevent vibration(3) When the centerline is verticalInstall a tensioner that can automatically eliminateexcess slack. This is particularly necessary whenthe drive shaft is on the bottom.TensionerGap of 2 to 4 mm betweenchain and contact surfaceFig. 22: Vertical transmission4.6 Lambda Curved Chain installation1) Installing the guideCompared to a standard chain, a Lambda CurvedChain has a larger gutter between the pins andbushes, providing a greater degree of freedom.

Handling of roller chain and sprocket5. Sprockets5.1 Hardening of the teethWhen a sprocket is used under the following conditions,the sprocket teeth must be hardened.1) When there is a small number of teeth (24 or less), and thespeed is 1/8 or higher of the maximum rotation speedindicated on the kilowatt ratings tables.2) When using small sprockets with a speed ratio of greaterthan 4:1.3) When a large load is used at low speed (when using theLow-Speed Selection Method).4) When using under conditions that will cause wear to the teeth.5.2 Number of teethAs many teeth as possible should be used on thesprocket on the high-speed shaft side to help ensuresmooth drive transmission. Generally, 15 or moreteeth should be used. However, when the speed ratiois high and the number of teeth on the low-speedsprocket exceeds 120, chain engagement problemscan occur when there is even slight chain wear. In thiscase, decrease the number of teeth on the highspeedsprocket, but the number of teeth should stillbe kept to 13 or higher. However, if the sprocket willbe used at extremely low speed and not subjected toshock, a sprocket with 12 or fewer teeth can be used.5.3 Precautions related to additional processing1) Shaft hole processingMaximum shaft hole processing dimensionsThe maximum finished shaft hole size should be ator below the size shown in the specifications foreach model number. Please consult Tsubaki if usingstandards other than the JIS standards key.Processing standardsa AWhen processing, verify thestandards for the tooth outerb Adiameter ("DO" in the diagram)Aand the hub outer diameter ("DH"in the diagram).DODHAlso, verify that the deflection onthe bottom of the tooth ("a" in theHubdiagram) and the deflection onTooth shapethe end surface of the tooth ("b" inthe diagram) are at or below thevalues shown below.2)3)When using machine specificationsDiameter oftooth-bottom cylinder 90 or less 90 but 190 190 but 850 850 but 1180 Greater than 1180Deflection at tooth bottom a 0.15 0.0008df0.08 0.76Face runout0.25 0.0009df0.08 1.14Sprocket weldingWhen welding a hub to A-type sprockets for use, thewelding can cause deformation or deflection of thetooth and surface, making it impossible to maintainproduct quality. As such, welding should be avoided.With the A-type strong series sprocket, welding canalso decrease the hardness of the sprocket, soagain, welding should be avoided.Processing on the hub outer diameterDo not perform any additional processing to theouter diameter of the hub.

Chain Test RunAfter installing the chain, carry out a test run and check the following items before you actually start running the chain.6.1 Pre-Test Run1) Connecting link plates, clips, and cotter pins areinstalled correctly.2) Chain slack has been properly adjusted.3) Adequate lubrication is available.4) The chain is not touching the chain case.5) The roller chain path is clean and free from obstructions.Step Step Step 6.2 Test-Run1) There should be no strange noises. Make sure thechain does not touch the case.2) Look for excessive chain vibration.3) Make sure the chain does not run up on the sprockets.4) Ensure that the chain is not jammed into the sprockets.5) The chain should articulate smoothly.Check the inspection items if there are any problems, and ensure roller chain and sprocket are correctly installed.7. Roller Chain Inspection1) In general, life of roller chain is said to be reached when parts are damaged or when 1.5% wear elongationoccurs. See 6) in 7.3. Try to replace the chain before these conditions occur.2) If roller chain selection and operating conditions are suitable, you can expect rather long life with nounexpected trouble from the chain. However, wear will progress between the pins and bushes after longperiods the following should be noted and inspected.7.1 Inspection Checklist (Table 7)ProceduresMethodVisually check the chainduring operation and lookfor any abnormalities.Stop the chain andcarefully inspect eachpart of the chain andsprocket.Inspection items1. There should be no strange noises.2. Look for excessive chain vibration.3. Make sure the chain does not run up the sprockets.4. The chain is not jammed into the sprockets.5. There are no stiff areas during articulation.6. Adequate lubrication is available (lubricating system and quantity of oil).7. Make sure the chain doesn't touch the case.1. Check the external cleanliness, corrosive, and lubrication conditions; also,look for scratches or other damage to the plate side and edge surfaces, pinedges, and roller surfaces.2. Inspect for pin rotation and the clearance between the plate and the pins.3. Inspect the sprocket teeth surfaces and teeth side surfaces for scratches or marks.4. Measure the wear elongation of the chain.5. Check the articulation of the chain and rotation of the rollers.6. When using an end fitting for lifting applications, inspect the wear of the endbolts and the wear of the connecting plate pins. Also, check for proper installationat the same time.In order to investigate in moredetail, remove the roller chain1. The inspection items are identical to those in Step except in more detail.and inspect it visuallly or checkit with measuring instruments.Reference pagefor detailsInspectionpoints are on thefollowing pagesand on thetroubleshootingpages.165

Handling of roller chain and sprocket7.2 Inspection intervalsRegular inspection of roller chain is recommend atone month intervals. Inspection should be carried outat shorter intervals in:1)2)3)Special or corrosive environments.High speeds with sudden stoppage.Lifting or indexing operations.7.3 Inspection requirements for ordinary transmission1) Inspection lubrication conditionsDuring operation, check to see if there is lubrication inthe clearance between the outer plate and inner plate.Also, check if the chain or rotating disc is immersed inlubricating oil.When the chain is stationary, the chain surface willgenerally appear dirty from wear dust if lubrication isunsatisfactory. This is especially the case between thelink plates.When the chain is removed, connecting link pins and theedge of the inside of the bushes should be checked. Ifthere are any scratches, red or reddish-brown color,lubrication is improper or insufficient.2) Inspecting link platesIf repeated loads over the maximum allowable loadare put on the chain, there is a strong possibility offatigue breakage of the link plate. It is difficult tonotice initial cracking from fatigue breakage simplyfrom external observation.Usually, a crack develops at the edge of a holeor at the side of the link plate, as shown in theillustrations below. The presence of cracks shouldbe checked carefully. Fatigue breakage progresseslittle by little, so it can be noticed with closeattention.Positions where cracksare likely to developFig. 23 Cracks on the link platesExample of a crackWhen wear occurs from sliding between the edgesof the plates and the guides, it is necessary toadjust the position of either the chain or theguides. The allowable wear on the link plates islimited to 5% of their height.H 5Fig. 24 Wear on the edges of the link plates3) Inspecting PinsWhen the pins rotate, the roller chain must becompletely replaced with new chain. This alsoapplies to the connecting pins. By removing theconnecting parts it is possible to see the conditionsof wear and rust on the surfaces of the pins.Correct position Rotated positionFig. 25 Rotation of the pins4) Inspecting rollersAs with the link plates, if rollers are also subjectedto loads over the maximum allowable load, therepeated impact load between the chain and thesprockets may cause fatigue breakage to occur.The roller should be checked in the same way asthe link plate.If foreign objects interfere with the engagement ofthe roller and sprocket, the roller may be damagedand a crack may develop. Careful attention shouldbe paid to the above. Furthermore, with high-speedoperations, even if foreign objjects do not interferewith engagement, cracks may appear from theimpact with the sprocket teeth.Fig. 26 Cracks on the rollersChains damaged by fatigue breakage from therollers must be completely replaced, as each parthas received the same amount of repeated load.Also check for poor roller rotation.5) Inspecting sprocketsChain and sprocket engagement can bechecked by observing the roller and teethsurface. Proper engagement is when the contactarea is uniform with point A in the illstration. If thecontact area is lopsided or the sides of the teethare wearing away (point B), this may have beencaused from improper installation of thesprockets or twisting of the roller chain. In thiscase, rechecking/readjustment is necessary.The normal point of impact is slightly up from thetooth bottom. However, when initial tension isapplied to the chain and tension remains on theslack side, the roller will slightly touch the toothbottom. However, point A receives the strongestimpact.Before Use For Safe Use Standard Roller Chains Lube-Free Roller Chains Heavy Duty Roller Chains Corrosion Resistant Roller Chains Specialty Roller Chains Accessories Selection Handling166

In thiscase, when replacing the chain, replacement ofthe sprocket is also recommended.6) Inspection of chain elongationChain elongation is caused not by deformation ofthe link plate, but by wear on the pin and bush.Therefore, the remaining chain life can beestimated by periodically measuring the chainelongation.Measuring chain elongation(1) The chain should be measured whilst stretchingit slightly to eliminate any slack.(2) Measure the distance of the inside (L1) andoutside (L2) of the rollers at both ends ofthe measured links using a vernier to get ameasurement (L).L L 1L 22(3) When measuring, use at least 6 to 10 links tohelp keep any measuring error down to aminimum.Positioning of vernier callipers for measuring 6 linksRollerFig. 28 Measurement of length(4) Finding the chain elongationChain elongation (%) =Measured length - Standard lengthStandard length100Standard length = Chain pitch X Number of links(5) For multi-strand roller chain, the measurementis carried out in the same way as for singlestrand roller chain of the same pitch.(6) The limit of usage based on roller chainelongation for a smooth transmission is asfollows.Limit of usage based on elongation (table 9)Large sprocket with up to 60 teethLarge sprocket with between 61 - 80 teethChain elongation 1.5Chain elongation 1.2Large sprocket with between 81 - 100 teethLarge sprocket with between 101 - 110 teethChain elongation 1.0Chain elongation 0.8167

Handling of roller chain and sprocket(7) Dimensions for evaluating standard length(chain pitch number of links) and 1.5% elongationare shown in Table 10 below.(8) When the length of the roller chain cannot bemeasured with a vernier, a tape measure maybe used; however, measurements need to betaken over as many links as possible to reducemeasuring error.(9) When chain elongation of Lambda/X-LambdaRoller Chain reaches about 0.5% it may belosing its lubricating properties. This may bedetermined by the adhesion of red wearparticles between the plates and the occurrenceof articulation stiffness.

Cautions on Use in Special EnvironmentsAs a general rule, roller chain should be used in a clean air flow; however, when used in a specialatmosphere, reference should be made to the various items that follow.8.1 Use in wet conditionsIf the chain is used in a sterilizing machine or water screen, for example, where the chain is splashed withwater or goes through heated vapor, the following problems may occur.1) An increase in abrasive stretch due to improper or insufficient lubrication.2) Decrease in fatigue strength from rust and corrosion (pitting) of the chain.1) Countermeasures(1) Reduce bearing pressure using a larger sized chain to improve wear resistance.(2) Use corrosion resistant roller chain for rust prevention.8.2 Use in acidic or alkaline conditionsIf roller chain is exposed to acids or alkaline conditions, such as battery acid and liquid used in platingprocesses, the following problems may occur.1) Embrittlement fracture of link plates and pins.2) Fatigue breakage of link plates and pins due to rust and pitting corrosion.3) Wear from usual mechanical abrasion and corrosion.4) Reduction in volume of the whole chain from corrosion.5) In special cases where the chain is underwater (immersed in liquid),electrochemical corrosion may occur.6) There are also circumstances where even stainless steel roller chain willcorrode. Fig. 31 shows an example of chain that was used in a platingapparatus. The chain fell to pieces within one month due to the affect ofthe acid.Fig. 31 Corrosion of stainless steel roller chain1) Countermeasures for embrittlement fractures (Stress corrosion cracking) Adopt a brittleness countermeasure that lowers crack susceptibility. Install a cover or casing to prevent acids or alkalis from contacting the chain. Adopt a high-grade material with anti-corrosive properties.2) Countermeasures for corrosion Use surface-treated chain. Install a cover or casing to prevent acids or alkalis from contacting the chain. Adopt a high-grade material with anti-corrosive properties.In general, embrittlement fractures (stress corrosion cracking) occur aroundthe link plate holes. This is the area where the pin and bush are press-fitted Fig. 32. Hydrogen embrittlement crackingto the link plate having the highest concentration of stress. Cracks aregenerated even when there is no tension on the chain. Roller chain ingeneral is more susceptible to acids than alkalis, and in special cases,embrittlement fractures (stress corrosion cracking) are generated byseawater or pit water.8.3 Use under conditions where abrasion is a problemIf the chain is exposed to strong abrasive materials that promote wear such as sand, coke and metalparticles, the following problems may occur:1) When abrasive materials penetrate between the pins and bushes, chain wear is promoted and poor articulationoccurs.2) When abrasive materials penetrate between the bushes and rollers, chain wear is promoted and poor rollerrotation occurs.3) When the abrasive materials penetrate between the link plates, poor articulation occurs.1) CountermeasuresApply a dust-protection casing.Remove foreign particles by regularly washing the roller chain.Reduce bearing pressure using a larger sized chain to improve wear resistance.Increase abrasion resistance by applying special processing to the parts of the chain where abrasion is aproblem.169

Occurs whenchain is subjected to a loadgreater than its breakage strength.Pin rotates or begins tostick out.NormalWear or rust occurs onlyat the connecting pin ina lifting application orsimilar operation.Excessively large shock loads.Subject to a repetitive load greaterthan the fatigue limit of the pin.Corrosion.Fatigue fractureOccurs when the pin is repetitivelysubjected to loads greater than itsfatigue limit. Re-check the size ofthe peak load and formulate acountermeasure.9.4 Bush / Roller RelatedSymptom Possible Causes RemedyRoller and/or bushingsplits. (Falls off)Roller does not rotate.Excessive load or improper lubrication.Operating a chain at high load withoutproper lubrication can create frictionbetween the pin and bush, causingthe pin to rotate. In this condition, thepin may come out, leading to chainbreakage.Improper initial lubrication at installation.Excessive load or speed of rotation.Inadequate lubrication.RS11-SS-1, RS15-1, RS25-1, RS35-1Reduce shock loads by making the start-up, stopping, andother actions smoother.Remove the large repetitive load. Otherwise, increase thesize or number of chains.Install a casing to protect the chain. Periodically clean andlubricate the chains.Shock-induced bending fractureThe pin is subjected to a large shock load andbreaks. The side with the initiating point receivestensile load, and the fracture progresses fromthis point. A pin is especially susceptible tobecoming weak with regard to bending whenthe surface of the pin has corroded. This type ofphenomenon occurs quite easily.Replace with new chain. Improve the lubrication or loadingconditions.Replace with new chain immediately. Do not weld orreuse the pins. (Dispose of the old chain to be sure that itis not used again by mistake.) Also, if the pin head or linkplate surface is worn, check the installation.Replace the connecting link. If pin wear is excessive,replace the chain also. Take special care to properlyinstall the connecting section for devices such as endbrackets used for lifting applications, etc.Choose a different chain according to the kW ratings table.Replace the chain. Provide adequate lubrication accordingto the operating conditions.Fatigue fracture.Reached the point of fatigue during operation and eventually broke. Impact withthe sprocket teeth at a force exceeding the chain's transmission capacity.The inner link plate is moving inward, orthe bush is cracked.A bushed chain and not a roller chain is being used.Replace with a new chain. Re-inspect the installation andload conditions.Foreign particles have gotten betweenthe bush and roller.Periodically clean the chain. Install a casing to protect thechain.Roller is opening up.Excessive load.Reduce the load. Provide adequate lubrication.173Roller is becominghourglass shaped.Excessive load or inadequatelubrication.Replace with new chain. Improve the lubrication or loadingconditions.
