Plastic Chain 

Linisort-V 

NEP Chain 

Did you know that many of TSUBAKI’s eco-friendly 

products are part of our daily lives? 

Eco-Friendly Products 

Reduce, Reuse and Recycle are the “three R’s” of environmental 

conservation. We develop products and technologies that 

contribute widely to environmental conservation. 

Recyclable Plastic Chain 

By collecting and recycling used plastic chains, we are promoting 

resource conservation and the adoption of recycling. 

Linisort Sorting Systems 

Linisort systems incorporate linear motors that provide silent, 

eco-friendly sorting. In addition to featuring a compact 

configuration, low weight, and low energy consumption, these 

systems are designed for environmentally friendly disassembly, 

part sorting, collecting and recycling. 

Eco Chain Series 

NEP chain is highly corrosion-resistant chain with a surface 

coating free from designated hazardous chemicals (RoHS Directive 

compliant). This product series also includes our Lambda Roller 

Chain, which offers superior oil-free and long-life characteristics; 

plastic roller chain, which features low-noise operation achieved 

with our proprietary engineering plastic technology, and stainless 

steel water processing chain, a field-proven product that has 

earned an excellent reputation after decades of successful use in 

wastewater treatment facilities throughout Japan.

Energy Series Chain - When Power Counts 

High productivity, high speeds, high shock loads, and high cyclic loading in the oil field put great demands 

on roller chain. Count on the experts at Tsubaki to deliver Energy Series — the chains you need to keep 

your operation running smoothly. 

Engineered for quality 

and performance 

Tsubaki builds performance into every Energy 

Series chain. We start with the highest-quality 

steel, manufacture all parts to stringent tolerances, 

and provide the most effective heat-treatment 

processes to maximize tensile strength and shock 

load resistance. That means long-lasting chain in 

the toughest applications. 

Pre-stressed for performance 

out of the box 

All chains are pre-stressed to ensure uniform 

load distribution and to minimize initial elongation. 

The result is better operation immediately following 

installation and throughout the life of the chain. 

Stronger pins for 

longer chain life 

Drilling applications put a lot of stress on pins, 

and pin wear can cause early chain failure. 

Energy Series pins are made of special materials, 

precision-ground to ensure accurate fit, and 

assembled only after our proprietary heat treatment. 

The result is tough, through-hardened pins that 

increase fatigue strength and allow the chain to 

better withstand shock loads. 

Ballized holes for 

smoother contact 

Fatigue cracks can start from imperfections in the 

plate holes. Energy Series chains are manufactured 

to minimize imperfections. After heat treatment, 

the pitch holes on the side plates are ball drifted 

to impart residual 

compressive 

stress and create 

extremely smooth 

hole surfaces, 

which maximizes 

fatigue strength. 

Z-cotters hold tight, minimizing 

vibration and maximizing fatigue 

life, yet allow easy assembly and 

disassembly in the field. 

Pitch-compensated link plates 

maintain maximum strength 

Energy Series link plates 

have wider waists, putting 

more steel where you 

need it to handle shock 

loads. The added plate 

strength creates a rigid 

link with less deflection 

under load. 

Centre plates are pitch-compensated, 

creating a contact fit that allows easy 

cutting and assembly while maximizing 

chain strength. The plates hold tighter 

and share the load equally, creating 

higher fatigue resistance and longer 

lasting chain. 

Factory-applied hot-dip lube penetrates deeper 

Building better bushings 

and rollers that last 

Roller and bushing 

designs play significant 

parts in chain life. 

Every Energy Series 

chain uses solid rollers, 

which are carefully 

formed from high-grade steel into optimal 

roundness and then heat treated and 

shot peened for toughness and strength. 

Energy Series features solid bushings 

for large sizes and precision-formed 

bushings for small sizes. Both types 

of bushings are fabricated to be the 

roundest in the industry for smooth, 

long-lasting operations. 

The final manufacturing step before chains are shipped is one of the most important. 

Tsubaki dips each chain in hot lubricant, so it penetrates deeper than typical surface sprays. 

This special step puts the lube where you need it — deep into the pin and bushing area — 

to extend the working life of the chain.

Energy Series Specification 

At Tsubaki we understand Oilfield grade. Our vast experience in providing sprockets and machined 

components to your industry has lead us to the development of the Energy Series specification. 

When you ask for Energy Series sprockets you get a list of standard features unique to the 

oilfield industry that provide confidence and value. (Energy Series sprockets are identified 

with the prefix EN). 

Energy Series standard features: 

• Sprocket wear indicator only from Tsubaki! 

Brass dowels are milled into the face of the plate 

at the precise calculated depth position 

• Eliminates the guesswork of opinion 

vs. mathematical fact 

• Preventative maintenance feature providing 

insurance against premature chain wear 

• Flame hardened not Induction. Flame hardening 

provides the best combination of strength and 

wearability because ductility remains in the root 

of the tooth whereas induction hardens everything 

• Minimum tooth hardness of 35Rc. Higher hardness 

can be achieved to customer specification 

• Fully machine-cut precision quality 

• Solidworks model provided after order stage 

• Certified documentation with minimum hardness 

and depth specification 

• Coupon testing provided on request 

• Milled serialized identification. 

Tooth wear indicator 

Only one supplier can manufacture both 

roller chain and sprockets, period. 

That means Reliability and Quality 

you can trust. 

Options 

There are many options available to you from Tsubaki. Rely on Tsubaki’s knowledge and 

experience to help you with a solution. Material and hardness specification are 

critical to maximizing performance (high carbon steel is Tsubaki standard). 

Here are some features to consider:

Design 

Consider Power-Lock ® AD series to transmit 

extreme torque levels (see pg. 38 for details). 

The use of Power-Lock ® can simplify design 

and reduce machining cost.

Power-Lock ® 

Power-Lock ® 

ENTER THE “KEYLESS” SOCIETY 

Our Power-Lock ® 

solves your problems. 

Tsubaki Power-Lock ® 

Offers a Whole New Approach 

to Replacing Keyways 

Eliminate backlash damage to 

keyways from heavy loads... 

Tsubaki Power-Lock ® fits tightly around the shaft/hub and is not 

affected by load reversals. 

End your high machining expenses for long shaft keyways, splined 

shafts, threads, grooves and steps…Tsubaki Power-Lock ® offers 

exacting, slip-free location. 

Erase the headaches of shrink-and-press fits. 

Tsubaki Power-Lock ® simplifies installation and removal. 

This easy-to-install unit slides into position and offers a 

keyless shaft-hub lock that will simultaneously handle 

both high torque and thrust while increasing your 

shaft strength. 

The Power-Lock ® is easy to assemble...you only need 

one tool. It is ideal for locking in large or small sprockets, 

gears, pulleys, timing cams and rollers. Best of all, 

the Power-Lock ® is in stock for immediate shipment. 

Features & Applications 

• High Durability Against Reversing or Impacting Loads 

The Power-Lock ® connection is not affected by tortional load reversal or impact, 

which damages the key and keyway connection. Tsubaki Power-Lock ® fits tightly around 

the shaft/hub and is free of backlash. 

• Easy and Precise Positioning 

The Power-Lock ® offers 360-degree angular adjustment and is excellent for indexing 

tables, cam mechanisms, gear drives and double-strand conveyor sprockets. 

• Thrust Capability 

Tsubaki Power-Lock ® can hold axial forces, too. Typical applications with these forces 

include indexing tables and bevel gears. 

• Easy Assembly and Disassembly 

The Power-Lock ® can be assembled and disassembled frequently, so maintenance 

or replacement of worn parts is simple and easy as compared to other methods (key and 

keyway, spline, shrink or press fits and welding). 

• Increased Shaft Strength 

By using the Power-Lock ® , no metal needs to be removed from the shaft (such as 

the cutting of a keyway). The strength of the shaft can be kept at its original diameter. 

This savings can be especially noted on hollow-shaft applications. 

• Eliminates Costly Machining 

There is no need for time-consuming machining of keyways. The Power-Lock ® 

offers substantial savings on long, heavy shafts.

required. Optimum performance is achieved with low shaft 

and hub tolerances minimizing the total machining costs. 

• Easy to Install 

Installs or removes just by tightening or loosening of bolts. 

No need to hassle with adjusting keyways and thermal 

fittings. 

• Options to Fit Every Application 

Stainless Steel and electroless nickel plating options are 

offered for standard models. Both are highly durable in 

corrosive or clean room environments.

4. Verify that the hub length (B) is adequate for the selected Power-Lock ® ; see example below. 

5. Check the applicable machining tolerance for the shaft and hub bore in the specification tables. 

A surface finish of 125 micro-inches for shafts and bores is generally adequate. 

AS Installation Guide 

Installation 

1. Verify that all contact surfaces, including the screw threads and screw head bearing surfaces, are clean and lightly oiled. 

Note: Do NOT use Molybdenum Disulfide, “Molykote” or any other similar lubricants. 

2. Slide the Power-Lock ® onto the shaft and into the hub bore, aligning them as required. 

3. Tighten the locking screws gradually in the sequence illustrated in Figure 1 below. 

The tightening sequence is as follows: 

a) Hand-tighten 3 or 4 equally spaced locking screws until they make contact. Align and adjust the connection. 

b) Hand-tighten and take up all remaining locking screws. 

c) Use a torque wrench to tighten the screws further to approximately one-quarter the specified torque 

(MA - as found in the AS Power-Lock ® specification tables). 

d) Increase the tightening torque to 1/2 of MA. 

e) Finally, use the torque wrench to tighten the screws to the full tightening torque (MA). 

f) Verify that the screws are completely tight by applying the specified tightening torque (MA). 

Notes: i) Even tightening is best accomplished by turning each screw in increments of approximately 90˚.

A sprocket is to be mounted on a 1.50" shaft capable of transmitting a peak torque of 400 ft-lb. The sprocket is made 

of 1144 steel with a yield point of 56,000 p.s.i. Select the proper Power-Lock ® and determine the required hub 

dimensions and proper machining tolerances. 

a. The shaft diameter (d) is specified at 1.50". 

b. The AS Power-Lock ® specification tables indicate that a 1.5" Power-Lock ® is capable of transmitting a torque (Mt) 

of 658 ft-lb, which is more than the required amount of torque (400 ft-lb) given in this example. Select the PL 1 1/2 

Power-Lock ® . 

c. Use the formula in step 3 in the Selection Guide on the previous page, to determine that the selected PL 1 1/2 

Power-Lock ® requires a minimum hub outer diameter (DN) of 3.03" based on Y.P. 56,000 psi hub material. 

d. The hub length (B) shown in Figure 1 should be > 2 x l. The specification table for AS Power-Lock ® PL 1 1/2 indicates 

that l = 0.709" therefore, B > 2 x 0.709 > 1.418. 

e. According to the AS Power-Lock ® specification tables, the machining tolerances for the selected AS Power-Lock ® 

are as follows: 

shaft (d): 1.50" +.000/-.0015". 

f. Order the following assembly:

possible.) 

Removal 

AS Power-Locks ® are not self-locking. The individual rings are tapered 

so that the inner and outer rings will spring apart after the last screw 

has been loosened. 

1. Loosen the locking screws in several steps following a diametrically 

opposite sequence. 

Do not remove the screws completely. 

2. Remove the hub and Power-Lock ® from the shaft. 

Note: If the AS Power-Lock ® is still locked even after loosening the 

bolts, then insert bolts into the jack screw holes (see photo beside) 

and screw them in until it unlocks.

Design Examples 

1. Hub mounting utilizing 

one Power-Lock ® . 

2. Hub mounting with 

Power-Lock ® 

located on 

opposite 

sides 

of hub: 

With this arrangement, twice the torque will be transmitted. 

3. Rigid shaft coupling 

mounting with two 

Power-Locks ® : 

4. Hub mounting 

in the middle 

of a shaft: 

Power-Lock ® can be used at any place on the shaft 

without keyway. 

5. Hub mounting utilizing two Power-Locks ® : 

In this arrangement, Power-Lock ® transmits twice the torque. 

6. Hub mounted on a stepped shaft: 

This arrangement is often used in conjunction with thin hub 

wall applications, for hubs with a straight-through bore. 

7. Lever or cam 

mounting: 

Positioning and 

adjusting are extremely easy.

AD Installation Guide 

Installation 

1. Verify that all contact surfaces, including the screw threads and screw head bearing surfaces, are clean and lightly oiled. 

Note: Do NOT use Molybdenum Disulfide, “Molykote” or any other similar lubricants. 

2. Slide the Power-Lock ® onto the shaft and into the hub bore, aligning them as required. 

3. Tighten the locking screws gradually in the sequence illustrated in Figure 1 below. 

The tightening sequence is as follows: 

a) Hand-tighten 3 or 4 equally spaced locking screws until they make contact. Align and adjust the connection. 

b) Hand-tighten and take up all remaining locking screws. 

c) Use a torque wrench to tighten the screws further to approximately one-quarter the specified torque 

(MA – as found in the AD Power-Lock ® specification tables). 

d) Increase the tightening torque to 1/2 of MA. 

e) Finally, use the torque wrench to tighten the screws to the full tightening torque (MA). 

f) Verify that the screws are completely tight by applying the specified tightening torque (MA). 

Notes: i) Even tightening is best accomplished by turning each screw in increments of approximately 90˚.

Tightening Sequence for 

Locking Screws 

(This is only an example - other 

number of locking screws is 

possible.) 

Removal 

AD Power-Locks ® are not self-locking. The individual rings are 

tapered so that the inner and outer rings will spring apart after 

the last screw has been loosened. 

1. Loosen the locking screws in several steps following a 

diametrically opposite sequence. 

Do not remove the screws completely. 

2. Remove the hub and Power-Lock ® from the shaft. 

Note: If the AD Power-Lock ® is still locked even after loosening the 

bolts, then insert bolts into the jack screw holes (see photo beside) 

and screw them in until it unlocks.

applications 

CTI components 

Tsubaki has the manufacturing experience with several key CTI wear components. The manufacturing complexity goes 

beyond what the eye can see. Details such as surface finish, strict tolerances, flatness, appropriate hardness levels and 

depth utilizing various heat-treat techniques and materials are all areas in which we have knowledge that you can rely on. 

Multi-axis machining capabilities ensure that components can be made from billet or forgings, for greater strength and 

durability. Certified welding techniques can help to mitigate the costs of some components where appropriate. Let our 

team of experienced engineers help you to decide where we can address cost and performance. Tsubaki’s attention to 

detail ensures that the smallest potential failure modes can be addressed prior to the manufacturing stage. 

CTI sprockets 

A critical component to the CTI unit is the sprocket. Single piece construction from billet or bar is our standard. 

High precision is maintained when machining both internal and external splines, bearing journals, sealing surfaces 

and any other feature that may be required. Higher precision tooth profiles ensure better chain engagement and torque 

transfer, reducing backlash torque loss from the drive unit to the chain. Wear indicators take the guesswork out of 

maintenance to ensure that proper engagement is maintained and the CTI is achieving maximum performance. 

Heat treatment methods are carefully selected and tightly controlled for CTI sprockets. As well, specialized coatings 

can help to mitigate the impact that the operating environment has on any exposed surfaces.

Manage your hydraulic hoses and cables with the correct specification by Kabelschlepp. 

Our bolted in aluminum bar options give you the strongest “box/cavity” strength versus 

a nylon carrier with “snap-in” cross bars. Due to the lower coefficient of friction, aluminum 

bars have been tested and proven to give you much better wear characteristics on cables 

and hoses versus nylon cross bars.

These sprockets are typically mounted with a large bolt circle pattern that 

requires precision in hole location. Tsubaki utilizes forged ring material which 

provides a cost reduction with the correct specifications. 

Typical layout: 

Sprockets: D100A148 X 50-1/2" PB (Driven); Range = 145 to 150 teeth

Exposure of the catwalk pipe conveyor and hard-to-access maintenance are concerns to consider. 

• Tsubaki Neptune offers corrosion protection with 

no compromise in strength. While Lambda chain 

provides maintenance-free self-lube operation. 

• Typical strand lengths for the catwalk are 

approximately 120 feet which can be supplied as a 

complete strand on reel.

Technical Services 


Drawworks 

At Tsubaki, we support what we sell. 

This means that we are your partner in reducing downtime, lowering maintenance costs and increasing productivity. 

Not everyone can say that. Tsubaki’s Technical Services staff is available for on-site inspections and will recommend 

the best solution for your application. We can also tailor our in-house seminar workshop to your individual needs. 

The extreme loads of a Drawworks operation demands the best. Multi-strand roller chain mating with large 

diameter sprockets have to be manufactured to tight tolerances, using correct materials and have hardness 

levels that relatively correct to each other. Confidence in one supplier to manufacture both is what you get 

with Tsubaki Energy Series roller chain and sprockets.
