Load carrying capacity and lifePermissible radial loadsPermissible radial loadunder dynamic loadingAttention!The thick-walled outer rings of the track rollers can support highradial loads. If these track rollers are used against a shaft as araceway, the outer rings undergo elastic deformation, Figure 1.Compared to rolling bearings supported in a housing bore,track rollers have the following characteristics:■ modified load distribution in the bearing.This is taken into consideration by the basic load ratings C rw andC 0r w that are decisive for life calculation.■ bending stress in the outer ring.This is taken into consideration by the permissible radialloads F rper and F 0r per . The bending stresses must not exceedthe permissible strength values of the material (due to the risk offracture).For bearings under dynamic circumferential load, the effectivedynamic load rating C rw is used.C rw is used to calculate the basic rating life.The permissible dynamic radial load F rper must not be exceeded.If the basic static load rating C 0r w is lower than the basic dynamicload rating C rw , C 0r w is used.121 603Figure 1Deformation of the outer ring whenused against a flat racewayPermissiblestatic radial loadAttention!For bearings under static load, when stationary or with onlyinfrequent motion, the effective static load rating C 0r w is used.C 0r w is used to calculate the static load safety factor S 0 .The permissible static radial load F 0r per must not be exceeded.In addition to the permissible radial load of the bearing,the permissible radial load of the mating track must also be takeninto consideration.The basic load ratings stated are valid only in conjunction with ashaft as a mating track that is hardened (at least 670 HV) andground (R a 0,3).Fatigue limit load The fatigue limit load C ur w is defined as the load below which –under laboratory conditions – no fatigue occurs in the material.12 LF 1 Schaeffler Group Industrial

Calculation of the rating lifeLife values for track rollersThe general methods for calculating the rating life are:■ the basic rating life to DIN ISO 281■ the adjusted rating life to DIN ISO 281■ the expanded calculation of the adjusted reference life toDIN ISO 281-4.These methods are described in Catalogue HR1, Rolling Bearings,in the section Technical Principles, Load carrying capacity and life.In comparison with Catalogue HR1, Rolling Bearings, the followingvalues must be exchanged:■ C r =C rw■ C 0r =C 0r w■ C ur = C ur w .The carriages LFCL, LFL..-SF, LFLL, LFKL and the bogie carriage LFDLcontain four track rollers LFR.The equivalent principle applies here.The corresponding parameters are taken into consideration inthe basic load ratings C y , C 0y , C z , C 0z and the permissible momentratings M 0x , M 0y and M 0z .C yNBasic dynamic load rating in y directionC 0yNBasic static load rating in y directionC zNBasic dynamic load rating in z directionC 0zNBasic static load rating in z directionM 0xNmStatic moment rating about X axisM 0yNmStatic moment rating about Y axisM 0zNmStatic moment rating about Z axis.In the case of track rollers with a profiled outer ring, calculation iscarried out exclusively by means of the basic rating life toDIN ISO 281.M 0zC y, C 0yxzM 0xC z, C 0zyFigure 2Load carrying capacityand load directionsxyzx yzM 0y121 686Schaeffler Group Industrial LF 1 13

Operating lifeThe operating life is the life actually achieved by a rolling bearing.It may differ significantly from the calculated rating life.This may be due to wear or fatigue as a result of:■ deviations in the operating data■ insufficient or excessive operating clearance (roller, guideway)■ contamination■ inadequate lubrication■ operating temperature too high or too low■ reciprocating motion with very small stroke length, which canlead to false brinelling■ vibration – false brinelling■ very high shock loads (static overloading)■ prior damage during installation.Due to the variety of installation and operating conditions, it isnot possible to precisely determine the operating life in advance.The most reliable way of arriving at a close estimate is bycomparison with similar applications.Schaeffler Group Industrial LF 1 15

Load carrying capacity and lifeStatic load safety factor The parameter for static loading is the static load safety factor S 0 .This indicates the security against impermissible permanentdeformations in the bearing and is determined by means of thefollowing formula:C0rwS0=F0rStatic load safety factorfor carriages with four track rollersAttention!Minimum loadAttention!CS r0 = 0F0MS0= 0MS 0NStatic load safety factorC 0r wNEffective static load rating according to dimension tableF 0rNMaximum radial load on track rollerC 0rNBasic static load rating according to dimension tableF 0NMaximum load in x, y, z directionM 0NmPermissible static moment in x, y, z directionMNmEquivalent static moment rating in load direction (M x , M y , M z ).Track rollers are regarded as heavily loaded at a static load safetyfactor of S 0 4.For applications with normal operating conditions, a value S 0 4 isrequired.When using individual track rollers, for example in conjunction withguideways, the permissible load of the guideway should be taken asdecisive where necessary.Static load safety factors S 0 1 lead to plastic deformations of therolling elements and raceway, which can impair smooth running.This is only permissible for bearings with small rotary motions or insecondary applications.In order to ensure that the outer ring is driven and to preventslippage or lifting of the track roller from the mating track,the track rollers must be subjected to a minimum load in dynamicoperation.In general, the minimum load is determined by the ratioC 0r w /F r 60.16 LF 1 Schaeffler Group Industrial

Differences in racewayhardnessIf shafts with a lower surface hardness are used (such as X46, X90),a hardness factor must be applied, see formula and Figure 3.CH= fH⋅CC0H= f0H⋅C0CNBasic dynamic load ratingC 0NBasic static load ratingC HNEffective dynamic load ratingC 0HNEffective static load ratingf H –Dynamic hardness factorf 0H –Static hardness factor.

LubricationLubricationof guideway racewaysLubrication intervalsAttention!Lubrication of track rollersFurther informationon lubricationThe guideway raceways must be lubricated (even before first use).Lubrication can be carried out by means of lubrication and wiperunits.These units are already integrated in the compact carriage LFKL.For carriages LFL and LFCL, the lubrication and wiper unit AB isavailable as an accessory, page 94.The guideway raceway is lubricated by an oil-soaked felt insert.Oil can be fed to the felt inserts via lubrication nipples in theend faces. At delivery, the felt inserts are already soaked with oil(H1 approval for the food industry), where relubrication is to becarried out an oil of vicosity 460 mm 2 /s is recommended.The lubrication intervals for guideway raceways are dependent onthe environmental influences. The cleaner the environment,the smaller the quantity of lubricant required. The time and quantitycan only be determined precisely under operating conditions sinceit is not possible to calculate all the influences in advance.A sufficiently long observation period must be allowed.Fretting corrosion is a consequence of inadequate lubrication and isvisible as a reddish discolouration of the mating track or outer ring.Inadequate lubrication can lead to permanent system damage andtherefore to failure. It must be ensured that the lubrication intervalsare reduced accordingly in order to prevent fretting corrosion.In general, a thin film of oil should always be present on the shaft.At delivery, track rollers LFR have an initial greasing of a high qualitylithium soap grease.From LFR5204-16, the inner ring has a relubrication hole.The smaller track roller diameters are lubricated for life.Further information can be found in Catalogue HR1,Rolling Bearings, in the section Lubrication.Figure 1Lubricationof guideway raceways155 26718 LF 1 Schaeffler Group Industrial

Design of bearing arrangementsRequirementsfor the adjacent constructionThe running accuracy of the linear guidance system is essentiallydependent on the straightness, accuracy and rigidity of themounting surfaces.The higher the requirements for accuracy and smooth running of atrack roller guidance system, the more attention must be paid to thegeometrical and positional accuracy of the adjacent construction.The adjacent surfaces should be flat and have parallel faces.For two guideways, we recommend parallelism to Figure 1.0,02Figure 1Parallelism of guidewaysShaft creepDisplacement forceLocation of carriagesand guidewaysUnder unfavourable conditions, shaft creep of a few millimetres mayoccur in isolated cases. This creep may occur mainly in applicationswith high accelerations in conjunction with high alternating loadsand guideways that are not completely supported. It may also becaused by an adjacent construction that is too soft.In such cases, shaft creep can be prevented by the use of endplates ANS.LFS; for information on end plates, see page 100.They can be supplied already mounted.The displacement force is dependent on the preload, the lubricationand the particular application. It is therefore not possible to makegenerally valid statements.If lateral loads are present, it is recommended that the guidewaysand carriages should be located against locating surfaces. In thecase of guideways comprising multiple sections joined together, itis recommended that the guideways should be aligned by means ofthe shaft. If necessary, the shafts should be located on the adjacentconstruction by means of dowels.If two guideways are arranged in parallel, the first guideway shouldbe clamped against a stop, Figure 1. The second guideway shouldthen be aligned accordingly. Any gaps between the guideway andthe adjacent construction should be filled with resin.121 269Schaeffler Group Industrial LF 1 19

Design of bearing arrangementsTrack roller guidance systemsin accordancewith customer specificationsThe INA track roller guidance systems with curved guidewayelements can be used to achieve an extremely wide variety ofapplications, Figure 2 and Figure 3.If the arrangement required cannot be represented using thestandard ordering designation, a customer drawing must besubmitted with the enquiry.For arrangements with curved guideway elements, it isrecommended that the guideway connector VBS should beused at the joints, see page 99. This gives considerably easiermounting.Figure 2Arrangement accordingto customer requirements121 55220 LF 1 Schaeffler Group Industrial

Track roller guidance systemwith compact carriageThe closed compact carriage LFKL..-SF gives a simple means ofachieving track roller guidance systems for operation incontaminated environments. The track rollers are protectedagainst contamination by the closed design. It has two integratedlubrication units for lubrication of the raceways.A compact carriage comprises a saddle plate made from anodised,profiled aluminium, four concentric bolts, four track rollers,two sealing strips and two lubrication and wiper units, Figure 2.The track rollers are already fitted, the sealing strips as well as thelubrication and wiper units are included loose in the delivery.Preload and clearance The carriages run clearance-free on all INA guideways, see page 38,and can be combined with all guideways of the relevant size,but not with the curved guideway elements LFSR. Due to the highlyaccurate guideways, it is not necessary to set the clearance.Sealing and lubricationCorrosion-resistant designFurther informationThe track rollers have gap seals on both sides, are greasedfor life and are therefore maintenance-free.For lubrication of the raceways, the lubrication and wiper units haveoil-soaked felt insert that can be replenished with oil via lubricationnipples. In combination with the sealing strips (gap seals),these units protect the compact carriage on all sides againstcontamination.All steel parts, the inner and outer rings of the track rollers and thebolts, washers and nuts are made from corrosion-resistant steel.The rolling elements are protected against corrosion by the grease.Corrosion-resistant designs have the suffix RB.Further information is given on the following pages:■ dimension table see page 50■ track rollers and bolts see page 60, 64■ guideways see page 66■ accessories see page 92.5 Sealing strip Lubrication and wiper unit Track roller Concentric bolt Saddle plateFigure 2Compact carriage1234121 312Schaeffler Group Industrial LF 1 43

Track roller guidance systemsTrack roller guidance systemwith open carriageThe robust open carriage LFL..-SF is suitable where efficient linearguidance systems of a simple construction are required.A carriage comprises a carriage plate made from anodisedaluminium, four screws and four track rollers, Figure 3.The track rollers are already fitted.Preload and clearance The carriages run clearance-free on all INA guideways, see page 38,and can be combined with all guideways of the relevant size,but not with the curved guideway elements LFSR. Due to the highlyaccurate guideways, it is not necessary to set the clearance.Sealing and lubricationCorrosion-resistant designFurther informationThe track rollers have gap seals on both sides, are greasedfor life and are therefore maintenance-free.The raceways can be lubricated by means of lubrication and wiperunits AB, page 92. Their oil-soaked felt inserts can be replenishedwith oil via lubrication nipples. In combination with sideplates ABAL, these units seal the end faces and longitudinal sidesof the open carriage, page 93.All steel parts, the inner and outer rings of the track rollers and thescrews, washers and nuts are made from corrosion-resistant steel.The rolling elements are protected against corrosion by the grease.Corrosion-resistant designs have the suffix RB.Further information is given on the following pages:■ dimension table see page 52■ track rollers and screws see page 60, 64■ guideways see page 66■ accessories see page 92.1121 662 Carriage plate Screws Track rollerFigure 3Open carriage3244 LF 1 Schaeffler Group Industrial

Track roller guidance systemwith non-locating carriageNon-locating carriages LFLL..-SF are robust, ready-to-fit linearguidance systems that are used exclusively in locating ornon-locating bearing applications with two parallel guidewaysystems. The track rollers can be axially displaced. In this way,it is possible to compensate for inaccuracies of 1 mm in relationto the spacing of the guideways.A carriage comprises a carriage plate made from anodisedaluminium, four screws and four non-locating track rollers, Figure 4.The track rollers are already fitted.Preload and clearance The carriages run clearance-free on all INA guideways, see page 38,and can be combined with all guideways of the relevant size,but not with the curved guideway elements LFSR. Due to the highlyaccurate guideways, it is not necessary to set the clearance.Sealing and lubricationCorrosion-resistant designAttention!Further informationThe track rollers have gap seals on both sides, are greasedfor life and are therefore maintenance-free.The contact zone between the raceways and track rollers must belubricated via the shaft.All steel parts, the inner and outer rings of the track rollers and thescrews, washers and nuts are made from corrosion-resistant steel.The rolling elements are protected against corrosion by the grease.Corrosion-resistant designs have the suffix RB (available byagreement only).Non-locating carriages must never be used on their own but onlyever in combination with locating carriages.The track rollers can support loads in a radial direction only.Further information is given on the following pages:■ dimension table see page 54■ track rollers and screws see page 60, 64■ guideways see page 66■ accessories see page 92.121 583a Carriage plate Screw Non-locating track roller1 2 3Figure 4Non-locating carriageSchaeffler Group Industrial LF 1 45

Track rollersFeaturesTrack rollers LFR are double row angular contact ball bearingscomprising an outer ring with a gothic arch profile, an inner ringand two ball and cage assemblies with plastic cages. The inner ringand outer ring are made from rolling bearing steel 100Cr6.The special outer ring gives two point contact in the contact zonewith the raceway, Figure 1. The contact angle is a maximum of30°.The bearings can support axial forces from both directions as well asradial forces.1 = 30° Gothic arch raceway grooveFigure 1Gothic arch,two point contact, contact angle121 608Schaeffler Group Industrial LF 1 61

AccessoriesFeaturesConnectors for guidewaysEnd platesAttention!Lubricationand wiper unitsType AB.WType ABGuideway connectors VBS are accessories for curved and straightLFS guideways.They comprise:■ pins■ bushes■ grub screws.The guideway connectors are suitable for all LF guideways.Curved guideways to be joined are supplied with the guidewayconnector as standard. Straight guideways to be joined can besupplied with the guideway connector as an option.The VBS reduces running noise at the joint, ensures an increasedoperating life for the guidance system and improves the operationalreliability.End plates ANS.LFS (also for use with hollow section guideways) aremade from steel. They secure the rolled-in raceway shafts by thephysical locking principle. In the case of solid section guideways,holes must be made in the end faces (by the customer) for screwmounting of the end plates.The end plates prevent the shaft creep that can occur underunfavourable conditions on all guideways that comprise analuminium support rail into which a steel shaft is rolledor pressed.These can be supplied already fitted, but this must be indicatedwhen ordering.The lubrication and wiper unit AB.W comprises a plastic housingand is fixed to the adjacent construction. It contains a feltlubrication insert. This is supplied soaked with oil that has H1approval and can be replenished with oil via a hole in the housingif necessary.Lubrication and wiper units AB.W are supplied with fixing screws.The lubrication and wiper unit AB comprises a plastic housing andis screw mounted to the end of the carriage LFL or LFDL. It containsfelt lubrication inserts on both sides. These are supplied soakedwith oil that has H1 approval and can be replenished with oil vialubrication nipples if necessary. The lubrication and wiper units ABcan be fixed to carriages using two screws.94 LF 1 Schaeffler Group Industrial

Cap wipersType AB.LFRThe cap wipers comprise a plastic housing and are slid over thetrack roller from below. They contain felt lubrication inserts on bothsides. These are supplied soaked with oil that has H1 approval andcan be replenished with oil via lubrication nipples if necessary.The cap wipers can be fixed using two screws to the screw mountingchannels in the carriage LFCL and thus seal the track rollers frombelow at the screw head. When bolts LFZ and LFE are used in anapplication design, there is a gap that can be sealed, for exampleusing silicone.Cap wipers are supplied with fixing screws.If two or more AB.LFR are used per side, the displacement resistancecan be reduced by removing the felt insert on the inner side.AB.LFR are suitable for mounting on the carriage LFCL42 as well ascustomer designs. For mounting on the carriage LFCL42, the uppercover must be replaced by the two covers supplied, Figure 1.21 For mounting on the customer design For mounting on LFCL42Figure 1Mounting on the carriage LFCLType AB.LFR5302An exception is the cap wiper AB.LFR5302. This comprises an endcover and a relubrication and wiper unit AB.W10 that can be screwmounted to either the right or left of the end cover.
