TSUBAKI RS ROLLER CHAIN – IMPROVED

Superior Impact ResistanceTsubaki chain has increased tensilestrength and approximately 20% greaterimpact resistance than ANSI standardchain. The Stress-Strain Curve belowillustrates how this extra Tsubaki strengthprovides greater protection againstdangerous ultimate strength failure.

Stress-Strain Curve

Improved Performance and Ease of UseWe have introduced productiontechnology for the chain bearing sectionthus eliminating the barrel shape of thebushing to give total surface contactbetween the pin and bushing. Thisimprovement results in a reduction ofinitial elongation and 20% improvement inwear life.

Greater Fatigue StrengthWhen you compare Tsubaki chains forfatigue strength performance, the factsput Tsubaki out in front. Compare the S-NCurve below for Tsubaki chains and seehow the competition fades.

S-N Curve

Higher Horsepower RatingTough Tsubaki chains not only last longerbut stand up to higher horsepowerratings. In fact RS35 and RS40 throughRS240 withstand 25% higher horsepowerratings. The improvement comes from aTsubaki exclusive ring coining process forthe slip fit connecting link and specialprocessing on the two-pitch off-set links.That means you can choose a smaller,less costly chain yet more than fulfill yourrequirements.

Assurance of Greater Fatigue StrengthThe wider waist of Tsubaki link platesensures greater fatigue strength for allchain sizes. Fatigue strength (max.allowable load) of each size can be foundin this catalogue.

Shot Peened PartsLink plates and rollers are shot peenedfor greater fatigue strength.

Factory PreloadingTsubaki roller chains are continuouslypreloaded on multi-sprockets after finalassembly as shown below. This results inminimum initial stretch.

Heat Treatment Ensures DurabilityChain durability depends to a great extenton the heat-treatment of the variousparts. The use of the most advancedheat-treatment methods and equipmentguarantees that Tsubaki roller chains arehighly durable.

PrelubricationA special lubrication is applied by Tsubakito bearing surfaces by hot dipping toextend chain life and reduce maintenancecost.

A Completely AutomatedManufacturing ProcessThe manufacture of Tsubaki roller chainsemploys advanced, automatedtechniques. The specialized equipmentused in each process ensures that allparts are uniform and high quality. Thephoto below shows the automatedpositioning of bushings.

Longer Wear Life & Less InitialAdjustment1) Tsubaki has decreased initial stretch

to 0.01% and increased wear life by asmuch as 140% over the competition.Where initial elongation is a problem,as in precision applications or whenyou simply demand the best, Tsubakiroller chain is the solution.

2) Our original prelubricant minimizesstretch to enable a vast increase in thechain's wear life.

3) Tsubaki bushings are "curl formed"from high quality cold rolled alloy steelinto a completely cylindrical shapewith uniform wall thickness.

4) Micron control has enabled Tsubaki toproduce perfectly straight bushingsand significantly reduce stretch duringinitial operation.

5) Improved Tsubaki roller chain sizesRS80, RS100, RS120, and RS140 lastup to 30% longer – even without re-lubrication. A Tsubaki innovation – alube groove (patent pending) on theinner surface of the bushing – retainsthe factory pre-lubricant oil.

CH

AIN

S Roller chains can be operated at speeds of up to 10,000 rpm. Even at high speeds, chain drive is quieterand smoother than a gear drive. You never have to worry about slippage as you would with a belt.

Roller chains are inherently elastic. Compared with gear drives, they soften shock and absorb vibration.They can be used in machines which are subjected to great shock or which constantly move or vibrate.Both the machine's body and bearing parts are protected against damage.

TSUBAKI RS ROLLER CHAINCONNECTION OF RS ROLLER CHAIN – IMPROVED

Roller chain is normally used as a continuous length witha connecting link, resulting in an even number of pitches.

Connecting LinksStandard connecting links are used when RS roller chain isoperated under normal conditions. For severe applications,press fit connecting links are suggested. In either case, aspring clip connecting link is used for RS roller chains of sizesRS60 or smaller, a cottered connecting link for sizesRS80 toRS200, and a spring pin connecting link for RS240. Acottered type connecting link is used for three to six strands ofRS40 to RS60. A cottered type can be provided for single anddouble strands of RS40 to RS60 upon request.

Standard connecting links have a slip fit cover plate.

The wider waist of Tsubaki's cover plates provides higherfatigue strength.

Installation of press fit connecting links may be less convenientthan that of standard connecting links, but performance isbetter. Press fit connecting links should be used in extremelyhigh speed or heavy duty applications.

The slip fit connecting links on improved Tsubaki chain have25% greater fatigue strength. These connecting links are ringcoined, which means improved capacity for your application.

Roller ChainA roller chain consists of roller links and pinlinks connected in series.

If a continuous length has an odd number of pitches, anoffset link must be used. However, the use of offset linksshould be avoided.

Offset LinksBoth two-pitch offset links and one-pitch offset links areavailable for RS roller chains. Tsubaki's redesigned link plateand improved manufacturing process make our two-pitch offsetlinks stronger than ever.

The two-pitch offset link is a combination of a roller link and anoffset link connected with a riveted pin. The connecting linkcan be attached to either side of a two-pitch offset link.

One-pitch offset links are very handy, but pin and offset linkplates have to be slip-fitted. One-pitch offset links are alsoweaker than plain chain and two-pitch offset links. Therefore,one-pitch offset links are not suggested, especially for frequenton-and-off operation, heavy impact loads, and high-speeddriving.

Note: Only two-pitch offset links are available for RS25.

Heavy SeriesHeavy Series roller chains differ from the ANSI standard series in the extra thickness of the linkplates and the extra length of the pins. These link plates have the same thickness as the link platesof ANSI chains having the next larger pitch. The thicker link plates provide greater capacity(approximately 10%) for absorbing shock loads. These chains are suitable in situations where theload is heavy or operating conditions are severe.

Sprocket for RS Double Pitch Roller ChainThere are special sprockets for RS Double Pitch roller chains. However, ANSI standard sprockets are alsoavailable for use, if the roller is a standard roller and the number of sprocket teeth is 30 or over. Pleasecontact Tsubaki for details of special sprockets.

Basic Formula for Chain Drive1) Chain speed: S

P•N•n12

P : Chain Pitch (inch)N : Number of teeth of sprocketn : Revolution per minute (rpm)

2) Chain tension: T33000xHP

SS : Chain Speed (ft./min.)HP: Horsepower to be transmitted (hp)

3) Number of pitches of chain: LN2–N1

N1+N2 6.282 C

N1 : Number of teeth (small sprocket)N2 : Number of teeth (large sprocket)C : Center distance in pitches

* Any fraction of L is counted as one pitch

4) Center distance in pitches: C18

+ (2L–N1–N2)2 – (N2–N1)2

Table II: Multiple Strand Factor

2) Use Table I to obtain the “Service Factor”.3) Multiply the horsepower value by the service

factor to obtain the design horsepowervalue.

4) Use Table IV on page A-24 and thehorsepower ratings tables on pages A-6 toA-19 to obtain the appropriate chain numberand the number of teeth for small sprockets.Refer to the number of revolutions of thehigh speed shaft (the driving shaft when thespeed is reduced; the driven shaft when thespeed is increased) and the designhorsepower value. For smoother chaindrive, a smaller pitch chain is suggested. Ifa single strand chain does not satisfy thetransmission requirements, use a multiplestrand chain. If there are space limitations, amultiple strand roller chain with a smallerpitch may be used.

5) After determining the number of teethnecessary for the small sprocket, refer tothe Sprocket Dimension Table (pages A-79to A-82) to check if the sprocket diametersatisfies the space limitations.

6) The number of teeth for the large sprocketis determined by multiplying the number ofteeth for the small sprocket by the speedratio. More than 15 teeth on the smallsprocket is suggested. The number of teethfor the large sprocket should be less than120. By reducing the number of teeth for thesmall sprocket, the number of teeth for thelarge sprocket can be reduced.

Horsepower RatingThe horsepower rating in Table IV on page A-24 is based on the following conditions:1) The chains are operated under ordinary

conditions. The ambient temperature rangemust be between 15°F and 140°F. Theyshould not be used in an atmosphere inwhich abrasive dust or corrosive gas ispresent or where the humidity is high.

2) The two transmission shafts are in ahorizontal position, and the chains areproperly installed.

3) The suggested lubrication system and oil areused.

4) The load does not change significantly duringtransmission. The “Service Factors” given inTable I should be taken into account whenthe chains are used under various operatingconditions. The load conditions will affect thelife of the chain.

5) The increase in the horsepower rating ofmultiple strand roller chain cannot becalculated simply by multiplying thehorsepower rating of one strand by thenumber of strands, since the load on eachstrand is not exactly the same. In order toestimate the service life of a multiple strandchain, the “Multiple Strand Factor” given inTable II must be used. When the chain lengthis 100 pitches and the above conditions aremet, a service life of approximately 15,000hours can be expected.

Procedures for Selecting Roller Chain1) The following factors must be considered

when selecting roller chain.a. Source of powerb. Driven machinec. Horsepower to be transmittedd. RPM of driving and driven shaftse. Diameter of driving and driven shaftsf. Center distance of the shafts

inches. The horsepower rating of a 15tooth sprocket for the RS60-3 shouldbe confirmed by the horsepower ratingfor the RS60 (see page A-11).

The horsepower rating of a 15 toothsprocket is 15.1 hp at 700 rpm and 17hp at 800 rpm. So the horsepowerrating at 750 rpm is about 16 hp. Since16 hp is for a single strand chain, thehorsepower rating must be multipliedby a multi-strand factor of 2.5 for atriple strand (see page A-22).

Therefore, the horsepower rating ofRS60-3, 15 teeth at 750 rpm is 40 hp(16X2.5=40).

Step 5 Refer to Sprocket Section (C)in this catalogue to check the diameterof the bore.

A 45 tooth sprocket meets the necessaryrequirement, but since the maximum borediameter (1.87 inches) of a 15 toothsprocket is smaller than the drive shaftdiameter of 2 inches, it can’t be used.

A 16 tooth sprocket with maximum borediameter of 2 inches must be used.Check again that the outside diameter,4.21 inches for 16 teeth and 11.89 inchesfor 48 teeth, is less than the spacelimitation (4.21 + 11.89<20).

A combination of RS60-3, 16 and 48teeth must be used to fulfill all thenecessary requirements.

Selection for Slow Speed

When the chain speed (S) is less than 160ft./min., select one RS roller chain sizesmaller than the chain chosen from thehorsepower rating method mentionedabove.

1. Tentatively select the chain andsprocket from Table IV (page A-24)and proceed by using a one sizesmaller chain and its sprocket with thenumber of teeth close to the sprocketselected above. Be sure to confirmthat the sprocket meets the applicationrequirements such as bore diameterand space limitation, etc.

2. Calculate the chain speed from thenumber of teeth on the drivingsprocket using equation (A). Alsocheck that the speed is less than 160ft./min.

3. Calculate the chain tension for theabove drive from equation (B).

4. Select the service factor and the chainspeed coefficient from Table I andTable III.

5. Verify that the chain has maximumallowable load which satisfiesEquation (C).

S= (ft./min.) . . . . . . . . . .(A)

S: chain speed (ft./min.)P: chain pitch (inch)N: number of sprocket teethn: revolutions per minute (rpm)T: chain tension (lbs.)HP: horsepower to be transmitted (hp)

There are two different ways to do thenext step: to increase the number ofteeth, or to use the same procedure forSuper Chains of the same size (refer toSuper Chains on pages A-35 to A-42).

Note: Please use connecting links forslow chain selection.

Table III: Chain Speed Coefficient

Selection for High TemperaturesTsubaki Improved Drive Chains aremade of heat treated carbon steel.When exposed to high temperatures,the mechanical properties of the heattreated chain components are lost.

1. The hardness and, therefore, thewear resistance of pins and bushingsis reduced.

2. At temperatures above 390°F, therollers and plates lose their hardnessand strength.

Standard roller chains can be used upto 500°F with the following adjustments:

3. Source of Power: Motor

4. HP to be transmitted: 40 hp

5. Drive shaft:Diameter 2 inches, 750 rpmDriven shaft:Diameter 3 inches, 250 rpm

6. Center distance:Less than 9 inches

7. Space limitation:Less than 20 inches

Step 2 Use Table I to determine theservice factor.

Service Factor SF = 1.0

Step 3 Obtain Design HPDesign HP = (HP to be transmitted) X SF

= 40 hp X 1.0= 40 hp

Step 4 Obtain the chain number andthe number of teeth on the smallsprocket from the tentative selectiontable (page A-24) referring to theabove 40 hp and 750 rpm.

Then check it by referring to therating tables (pages A-6 to A-19).

1. According to the horsepower rating,the best choice would normally be asingle strand of RS80-17 teeth. Sincethe speed ratio is 1/3 (250/750 rpm),the necessary number of sprocketteeth would be 17 for the smallsprocket and 51 for the largesprocket. But, as the outsidediameters are 5.94 inches for 17 teethand 16.81 inches for 51 teeth (refer tosprocket dimensions on pages A-79to A-82), it exceeds the spacelimitation of 20 inches (5.94 +16.81>20 inches).

Therefore, these sprockets are notsuitable.

2. As a single strand chain is notsuitable a multiple-strand RS60-2, 22and 66 teeth would be possible. Butthis combination is not suitable due tothe space limitation again (5.67 +16.18>20 inches).

3. For triple strand, RS60-3, 15 and 45teeth would be possible.

The sprockets’ diameters are 3.90inches and 11.18 inches respectively,the sum of which is less than 20

How to use this table:1. Example ... Design horsepower — 7 hp

a) Assume that the RPM of the small sprocket is 100.Judging from the intersection point of the design horsepower’s value of 7 hp and the RPM value of 100, RS80 and a sprocketwith either 17 teeth or 18 teeth can be selected. Sprockets with 17 teeth are more economical than those with 18 teeth.

b) Assume that the RPM of the small sprocket is 300. An RS60-15 tooth sprocket is appropriate from the intersection point in thesame manner as above. The line for RS50-24 teeth can also be seen near the intersection of 7 hp and 300 rpm. Therefore,either RS60-15 teeth or RS50-24 teeth can be selected. This table is used to make a tentative selection. The horsepower ratingtable should be used to determine the most appropriate chain and sprocket.

2. Horsepower lines of 20, 24 and 30 teeth sprockets are shown only in the high speed range on the right hand side of the abovechart. When checking the horsepower line of these sprockets, make a line parallel to the other lines on the left hand side of thedotted line for RS50-24 teeth.

3. When using a chain in the white part on the right side of the table, please consult with Tsubaki.4. When the chain speed is less than 160 ft./min., it is more economical to select your RS roller chain by the selection method for

slow speed drives (see page A-23).

* R indicates riveted, C indicates cottered pins.** Width between roller link plates (W) is slightly narrower than ANSI standard, however this chain runs on

standard sprockets.Notes:1. Drive and Conveyor series LAMBDA chains cannot be intercoupled or interchanged.2. The heavy roller link plates slightly increase the width, which means Drive LAMBDA connecting links are

required.

3. Connecting links for RSDT80-LAMBDA to RSDT100-LAMBDA and RSDT80(H)-2LAMBDA toRSDT100(H)-2LAMBDA have cottered pins.

4. Double Strand Drive LAMBDA II requires heavy-series sprockets.5. LAMBDA II roller link plates are nickel-plated for easy identification.

LAMBDA for international standards• For temperatures up to 302°F.• Replaces BS/DIN chain.• Cost effective, lube-free operation.

Benefits� Semi-Press Middle Link PlatesMiddle link plates have a shorter pitch thanthe pin link plates creating a contact fit. Thisallows for easier cutting and assembly of thechain without sacrificing its horsepowerrating.

� Meets API 7F SpecificationTsubaki “V” Class chain is manufacturedaccording to the API specification 7F, OilField Chain.

� Superior Impact ResistanceThe pin surface is carburized and hardened byTsubaki heat-treating techniques for superiorimpact resistance. This results in greaterbreaking strength and increased chain wear lifecompared to ANSI standard chains.

� Greater Fatigue StrengthLink plates are ball drifted after heat-treatmentfor greater fatigue strength. This results in a30% increase in chain life compared to our ANSIstandard chains.

� High Speed DurabilityRollers, precisely manufactured, are shot-peened after heat-treatment to give themsuperior fatigue life and high speed durability.

Note: Shepherd’s crook type cotter ( ) will be supplied unless otherwise specified.

BCL (bushed type connecting links) may be employed formultiple strand chain and are avaible on a special requestbasis only. The cover plate is designed for a snug press-fiton the pins for use on drives that are subjected to highspeeds and heavy shock loads. Removal of the press-fittedpin may be less convenient than that of ordinaryconnecting links but better fatigue strength is provided.The current standard connecting link is cotter pin typecomplete with loose-fit middle link plates.

Press fit offset link plates are used. It is suggested thatoffset links be used only when an odd number of linkscannot be avoided.

Super ChainProven Performance

ANSI standard roller chains are widely used in variousindustries. To meet the insistent demands of heavy industry,construction and agriculture, stronger and higher performingchains which can replace the corresponding ANSI standardchains are necessary. Tsubaki offers a line-up of Super andUltra Super Chains which will solve your specific driving andconveying problems relating to heavy shock load and/orspace limitations.

SUPER ROLLER CHAIN SUPER 80 ˜ 240High fatigue and tensile strength allow the selection of a chain one size smaller than wouldbe required with standard chain.

Pins constructed of “high toughness”steel give this chain exceptional abilityto absorb shock loads.

The link plate holes are ball drifted toobtain high fatigue strength.

If you have a problem like breakage of pins due to heavy shock loads, we suggest that you use either the T Series or the HTSeries.

If you have problems such as fatigue breakage of link plates, generally poor performance, or a space limitation, we suggestthat you use the Super Series, Super-H Series or Ultra Super Series. You may be able to use the next smaller size chain oreven a chain two sizes smaller.

T SeriesT Series chains have greater shock load resistance and higher ultimate tensile strength than comparable ANSI standard roller chains.This is accomplished by using through hardened pins. The dimensions of the chains are identical to ANSI standard roller chains.

HT SeriesHT Series chains have a greater ultimate tensile strength (plus 15-30%) than ANSI standard roller chains by using through hardenedpins and link plates of the next larger chain size. These chains also provide greater shock load resistance. The dimensions of thechains are identical to those of the ANSI Heavy Series standard roller chains.

Super SeriesThe dimensions of Super Series Chain are identical to those of ANSI standard roller chain. Super Series Chain has a wider waist linkplate than our standard chain and special manufacturing techniques are used to produce the pitch holes. After heat treatment theholes are then ball drifted for greater fatigue strength. The pins are through hardened for greater shock resistance. Because of this,Super Series Chain has a Maximum Allowable Load 25-30% higher than our standard RS roller chain.

Super-H SeriesSuper-H Series Chain has the same wide waist as Super Series. The link plate thickness is identical to those of the ANSI HeavySeries roller chains. The same special manufacturing techniques used in Super Chain are used to produce the pitch holes. The pinare through hardened. Because of this, Super-H Series Chain has an even higher Maximum Allowable Load than the Super Series.

Ultra Super SeriesTsubaki Ultra Super Series has a greater ultimate tensile strength and allowable load than any other roller chain we manufacture. Withthe Ultra Super Series, a chain up to 2 sizes smaller than standard can be selected.

DRIVE CHAIN SELECTION

Chain Drive SelectionGenerally, Super Series chains aresuggested when the chain speed is lessthan 160 ft./min. and where the RS rollerchain or the ANSI Heavy Series are notstrong enough to meet the applicationrequirements.1)Tentatively select the chain and

sprocket with the same size andnumber of teeth as used in “Selectionfor slow speed” on page A-23.

2)Calculate the chain speed from thenumber of teeth of the driving sprocketusing equation (A) and check whetherthe speed is less than 160 ft./min.

3)Calculate the chain tension necessaryfor the above drive from equation (B).

4)Select the service factor and the chainspeed coefficient from Tables I and II.

5)Select the suitable chain and verify thatthe chain satisfies equation (C).

For details, refer to Table I on page A-22.

The following three lubricating systems are suggested:

System A

System B

System C

Manual lubricationThe oil is applied with an oil can or brushin the gap between the pin and roller linkon the slack side of the chain. It shouldbe applied about every eight hours or asoften as necessary to prevent thebearing areas from becoming dry.Suitable chain speed is to be below 50ft./min.

Drip lubricationA simple casing can be used. The oil issupplied by a drip feed. Each strand ofchain should ordinarily receive 5 to 20drops of oil per minute. The amount isincreased as the speed increases.Suitable chain speed is from 50 to 100ft./min.

Oil bath lubricationThe chain is installed in a leak-freecasing. The oil depth of “h” should be 1/4to 1/2 inch deep. If the oil is too deep, itwill be adversely affected by the heatgenerated. Suitable chain speed is from100 to 160 ft./min.

SELECTION PROCEDURE

1) The following factors must beconsidered when selecting rollerchains for transmission needs.• The power to be transmitted.• The speed and the diameters of the

driving shaft and the driven shaft.• The distance between the centers of

the shafts.

2) Use Table I to obtain the “servicefactor”.(The “Service Factor” table refers tothe type of machine and source ofpower.)

3) Multiply the HP value by the servicefactor to obtain the design HP value.

4) Use Table III page A-52 to obtain theappropriate chain number and thenumber of teeth of the small sprocketby referring to the number ofrevolutions of the high speed shaft(the driving shaft when the speed isreduced; the driven shaft when thespeed is increased) and the designHP value. For a smoother chain drive,a smaller pitch chain is suggested. If asingle strand chain does not satisfythe transmission requirements, use amulti-strand chain. If the distancebetween the shafts and the diameterof the sprockets must be relativelysmall due to space considerations, amultiple strand roller chain with asmaller pitch may be used.

5) After determining the number of teethfor the small sprockets, confirm if thesprocket will meet the shaft diameterrequirements.

6) The number of teeth for the largesprocket is determined by multiplyingthe number of teeth for the smallsprocket by the speed ratio. While it ispreferable that the number of teeth forthe small sprocket be greater than 15,it is suggested that the number ofteeth for the large sprocket not exceed120. By reducing the number of teethfor the small sprocket the number ofteeth for the large sprocket can alsobe reduced.

The selection table is based on thefollowing conditions:1) The chains are operated under ordinary

conditions. The ambient temperaturerange is between 15°F and 140°F. Theyare not to be used in an atmospherewhere abrasive dust or corrosive gas ispresent or when the humidity isexceptionally high.

2) The two transmission shafts are in ahorizontal position and the chains areproperly installed.

3) The suggested lubrication system shownon Table IV is used.

4) The load does not change significantlyduring transmission.The “Service Factors” given in Table Iare used when the chains are usedunder various operating conditions. Theload conditions will affect the life of thechain. The increase in the horsepowerrating of multiple-strand roller chainscannot be calculated simply bymultiplying the horse-power rating of onestrand by the total number of strands,since the load on each strand is notexactly the same. In order to estimatethe service life of a multiple-strandchain, the “Multiple-Strand Factor” givenin Table II must be used.

Note: Refer to page A-77 for details of lubrication system.

Example

Data:1. Type of application: Centrifugal Blowers2. Source of power: Electric Motor3. HP to be transmitted: 40 hp4. Driving shaft: 600 rpm5. Driven shaft: 200 rpm6. Center distance: 19 inches7. Space limit: Max. 24 inches

Step 1 Use Table I and determine theservice factor.Service factor (SF) : 1.0Step 2 Obtain design HPDesign HP= HP to be transmitted X SF

= 40 hp X 1.0= 40 hp

Step 3 Obtain the chain size and thenumber of teeth of the small sprocket fromthe selection table for 40 hp and 600 rpm.

According to the selection table, the selectedchains and sprockets rpm are:(a) RS12B-3 chain and 25 tooth sprocket(b) RS16B-2 chain and 17 tooth sprocket(c) RS16B-1 chain and 25 tooth sprocket

* For (a), the necessary number of teeth forboth small and large sprockets is 25 teethand 75 teeth respectively, since the speedratio is 1/3 (200/600 rpm). But the outsidediameter of both sprockets 6.3 inches for 25teeth and 18.3 inches for 75 teeth exceedsthe limitation (6.3 inches + 18.3 inches>24inches). Therefore, these sprockets cannot beinstalled.

* For (c), the necessary number of teeth forboth small and large sprockets is 25 teeth(outside dia. 8.4 inches) and 75 teeth (outsidedia. 24.4 inches) respectively. It exceeds thespace limitation again (8.4 inches + 24.4inches>24 inches).

* For (b) the necessary number of teeth forboth the small and large sprocket is 17(outside dia: 5.9 inches) and 51 (outside dia:16.8 inches). It satisfies the space limitation(5.9 inches + 16.8 inches<24 inches). Acombination of RS16B-2, and 17 teeth and51 teeth must be used to fulfill all thenecessary requirements.Step 4 Use Table IV and determine thelubrication method.

Chain speed (S) = P • N • n12

= 1 X 600 X 17 = 850 ft./min.12

System B is suggested.Step 5 Obtain the number of pitches ofchain (L).

Anti-CorrosiveHeat ResistantChainWP® CHAINWP Chain resists corrosion when exposed to harsh outdoor environments including seawater. The exclusive WP surface treatmentprocess gives the chain its unique matte grey color and provides a protective finish that is more corrosion resistant than Nickel-Platedchains. WP Chain has the same high maximum allowable load as our standard carbon steel roller chain.

NICKEL-PLATED CHAINNickel-Plated chains provide acceptable performance where equipment must operate in mildly corrosive environments.

400 CS SERIESCS Series chains combine non-hardened side plates made of AISI 430 and round parts made of 304 stainless steel. An economicalalternative to other stainless chains in less corrosive environments.

600 AS SERIESAS Series chains are an excellent choice for drives requiring both corrosion resistance and high load capacity. Link plates are madeof 304 stainless steel and the round parts are made of hardened 600 series stainless steel. Of all the stainless steel chains offered byTsubaki, AS Series has the highest load capacity. Use where stainless steel is required by FDA regulations.

304 SS SERIESSS Series chains are made completely of 304 stainless steel. SS Series has an excellent resistance to corrosion & temperatureextremes. It is generally considered non-magnetic, although some permeability can be found in these chains. This is caused by thecold working of the components during the manufacturing process. If more complete non-magnetic permeability is required, wesuggest our NS Series.

316 NS SERIESNS Series chains are made completely of 316 stainless steel. It is the most corrosion resistant standard stainless steel chain offeredby Tsubaki. It also has the highest resistance to temperature extremes, and is sometimes referred to as our non-magnetic seriesbecause of its extremely low magnetic permeability. The load capacity of 316 NS Series is equal to that of our 304 SS Series.

POLY-STEEL CHAINPoly-Steel Chain is made of molded engineered plastic with 304 stainless steel pin links. This combination effectively incorporates theadvantages of both materials into one chain. Poly-Steel Chain from Tsubaki has superior wear life, excellent corrosion resistance, andrequires no lubrication. This design provides a quiet, lightweight chain for economical solutions to difficult application problems.

TITANIUM TI SERIESTI Series chains are made completely of Titanium. Available in sizes RS35TI - RS60TI, TI Series brings the unique properties ofTitanium to roller chain applications, specifically extreme corrosion resistance in a lightweight chain. Available on a made to orderbasis in the same dimensions as the 304 SS Series. Call Tsubaki for further details.

� Additional Information1. Offset links are not available. Please use an even number

of links.

2. Existing RS standard sprockets can be used.

3. RF40PC to RF60PC use the same connecting links asstainless steel chain. RF25PC and RF35PC use specialconnecting links.

4. When replacing stainless steel chain with Poly-SteelChain, please check the chain tension. Chain tensionshould be less than the maximum allowable tension.

5. Ambient temperature range: -14°F ~ 176°F(-10°C ~ 80°C)

6. Maximum chain speed: less than 230 ft/min.

7. Coefficient of sliding friction between chain and guide railis 0.25 (without lubrication).

8. The guide rail should support the bottom side of the links.

9. The colour of the inner links is BROWN.

� Connecting and Disconnecting1. Disconnect as follows:

As shown in the drawing, place the pin link plate on the jigand press down on the pin heads. Please be careful not toapply too much pressure to the plastic portion as there isthe possibility of breakage.

2. Please inquire about our disconnecting jig.

3. For connecting, please use a connecting link.

Leaf Chain

Leaf chains generally have greater tensile strength thanroller chains, and run over sheaves rather than sprockets.They are most often used as counterweight chains formachine tools, elevator and oven doors, fork lift truck masts,spinning frames and similar lifting or balancing applications.BL series can, in most instances, replace the older AL seriesLeaf chains; consult Tsubaki for interchange information.

These chains are supplied with male or female terminationsto allow addition of various clevises as desired.

GENERAL CAUTIONS1. Use lengths of factory assembled chain. Do not build lengths from individual components.

2. Do not attempt to rework damaged chains by replacing only the components obviously faulty. The entire chain may be compromised and should be discarded.

3. Never electroplate assembled Leaf chain or its components. Plating could result in failurefrom hydrogen embrittlement.

4. Welding should not be performed on any chain or component. Welding spatter should neverbe allowed to come in contact with chain or components.

5. Leaf chains are manufactured exclusively from heat treated steels and, therefore, must notbe annealed. If heating a chain with a cutting torch is absolutely necessary for removal, thechain should not be reused.

6. Joining chains together should only be done by the chain manufacturer.

7. The Minimum Ultimate Strength of a chain means the minimum load at which it will breakwhen subjected to a destructive tensile test. It does not mean working load.

8. Chains from different manufacturers should not be used in the same application.

Lube-Free Chain

FX Chain

For use where normal lubrication is not practical, i.e., food processing equipment, packaging machines, printing and binding equipment, and textile machines.High quality lubricant is impregnated into the sintered metal bushings. Joint movement between the pin and bushing releases the necessary volume of oil to the pin surface and other parts, thereby minimizing chain elongation and eliminating the risk of chain seizure from insufficient lubrication.See our Drive Series Lambda ® (page A-26) and Conveyor Series Lambda chains inSection “B” for additional specifications on other lube-free chains.

FX CHAINSTsubaki FX chains feature excellent durabilityand flexibility for tough applications such as inconcrete mixers, earth moving equipment, andmining machines.1. FX chains are interchangeable with ANSI

standard chains and can operate on thesame ANSI standard sprocket.

2. Increased clearance between pins andbushings allows the chains to accommodatea 4 inch lateral side bow and an 8 degreetwist per 4 feet of chain.

INSTALLATION AND ARRANGEMENT

Speed Ratio and Chain Wrap

The sped ratio of the roller chain can rangeup to 7:1 under normal operatingconditions. However a speed ratio of 10:1 ispossible if the speed is very slow. Chainwrap on the small sprocket must be at least120 degrees.

Distance Between Shafts

Sprockets can be separated by anydistance as long as their teeth do not touch.Optimum distance is 30 to 50 times thepitch of the chain used except when thereis a pulsating load. In such cases, thedistance should be up to 20 times the pitchof the chain used.

Position

Roller chains are ideally installedhorizontally. When chains are installed atangles approaching the vertical, theystretch quickly and may slip off thesprockets. In such cases the sprocketsshould be adjusted properly.

Slack

Generally, the slack of a roller chain shouldbe on the lower side (see Fig. A). Adequateslack (SS’) is 4% of the span for normaldrives. In the following cases, the slackshould be about 2% of the span.a. Vertical drive or close to vertical drive.b. Center distance between two shafts is

greater than 3 ft.c. Chain is operated under heavy load and

high frequency of on and off drive.d. Direction of the drive is often changed.

Position of Sprocket

The two shafts should be parallel andpreferably in a horizontal position.Sprockets should be firmly installed.(See Figs. B and C)Use a straight edge to check that the twosprockets are installed along the samehorizontal plane.

ArrangementWhen designing roller chain drives, thecenterline of both sprockets should be closeto horizontal (see Fig. D and E). The angleof inclination can be up to 60° as shown inFig. F and G.If installation is close to vertical, it isdesirable to install an idler or a guidestopper to maintain smooth engagement ofthe chain and sprocket.

Attention should be paid to the followingarrangements.If the slack side is on the top, it isnecessary to eliminate excessive chainslack.

A-1. When the center distance is short,chain slack should be adjusted byincreasing the center distance.

A-2. When the center distance is long,chain slack should be adjusted by installingan idler.

B. If vibration occurs due to high chainspeed, install a guide.

C. If the centerline is vertical, install anidler which functions automatically toeliminate extra chain slack. If the drivingshaft is on the lower side, an idler must beinstalled.

* Clearance between chain and guide should be 5/64" to 5/32"

LUBRICATION

A -

DR

IVE

CH

AIN

S Lubrication Increases theService LifeOne of the most important factors in gettingthe best possible performance out of yourroller chain is proper lubrication. No matterhow well a transmission system isdesigned, if it is not properly lubricated, itsservice life will be shortened.

LubricationWear between the pin and bushing causesthe roller chain to stretch. These partsshould, therefore, be well lubricated. Thegap between the pin link plate and the rollerlink plate on the slack side of the chainshould be filled with oil. This oil forms a filmwhich minimizes wear on the pin andbushing, thus increasing the chain’s servicelife. It also reduces noise and acts as acoolant when the chain runs at highspeeds.

Suggested LubricantsOnly high quality oil should be used tolubricate the roller chain. Neither heavy oilnor grease is suitable. The viscosity of theoil used will depend on the chain size,chain speed and ambient temperature. Thelubricants suggested for specifictemperature ranges are given in thefollowing table.

The following three lubricating systems are suggested:

Manual LubricationOil is applied with an oil filler or brush in the gapbetween the pin link and roller link on the slack sideof the chain. It should be applied about every eighthours or as often as necessary to prevent the bearingarea of the chain from becoming dry.Always turn off & lockout the power switch beforelubricating or servicing a chain system.

Drip LubricationA simple casing can be used. The oil is supplied bydrip feed. Each strand of chain should ordinarilyreceive 5 to 20 drops of oil per minute, according toincreases in the chain speed.

Oil Bath LubricationThe chain is installed in a leak-free casing. The oildepth “h” should be 1/4 to 1/2 inch deep. If the oil istoo deep, the oil will be adversely affected by theheat generated.

Lubrication by Slinger DiscInstall the slinger disc in a leak-free oil casing. Oil issplashed on the chain. The circumferential speedshould be at least 700 ft./min. If the width of the chainis greater than 5 inches, attach slinger discs fromboth sides. The oil depth of “h” should be from 1/2 to1 inch deep. The chain should not pass through theoil.

Lubrication Using a PumpUse a leak-free casing. A pump is used to circulatethe oil which is then cooled.The number of supply holes should equal Z+1 whereZ is the number of strands of chain. The amount of oilsupplied to each hole is constant.

Regardless of the lubricating system used, the roller chain must be washed periodically withpetroleum or gasoline. Examine the pin and bushing after removing the chain. Any damage orreddish-brown colour on their surfaces indicate that the system is not being adequately lubricated.

USE CARE TO PREVENT INJURYCOMPLY WITH FOLLOWING TO AVOID

SERIOUS PERSONAL INJURY:1. Guards must be provided on all chain and sprocket installations in accordance with provisions of

ANSI/ASME B15.1 — 1996 “Safety Standards for Mechanical Power Transmission Apparatus”, andANSI/ASME B20.1 — 1996 “Safety Standards for Conveyors and Related Equipment”, or otherapplicable safety standards. When revisions of these standards are published, the updated editionshall apply.

2. Always lock out the power switch before installing, removing, lubricating or servicing a chainsystem.

3. When connecting or disconnecting chain:a. Eye protection is required. Wear safety glasses, protective clothing, gloves and safety shoes.b. Support the chain to prevent uncontrolled movement of chain and parts.c. Use of pressing equipment is suggested. Tools must be in good condition and properly used.d. Do not attempt to connect or disconnect chain unless you understand chain construction,

including the correct direction for pin/rivet removal or insertion.e. Do not attempt to rework damaged chains by replacing only the components obviously faulty. The

entire chain may be compromised, and it should be discarded.

4. Other cautions:a. Alterations and Repairs to chains should be made only by qualified personnel with parts and

componenets authorized by Tsubaki.b. Electroplating of Assembled Chains is not condoned. Plating of assembled chains could result

in failure from hydrogen embrittlement.c. Inspect Chains for shipment damage before installation. During operation, all chain systems

should be inspected on a regular schedule. Visually check for worn, damaged and broken partscaused by improper installation or maintenance, abnormal stress, temperature, humidity, abrasionor corrosion, possible interference with other system components and improper lubrication. (Forcorrect lubrication procedures and systems, see the Engineering Section.)

d. Heating Chain with a cutting torch is not suggested unless absolutely necessary for removal. Ifcut in such a manner, it should not be reused.

e. Welding should not be performed on any chain or component.f. Average Ultimate Strength of a chain means the average load at which it will break when

subjected to a destructive tensile test. It does not mean working load.For complete information,contact Tsubaki Engineering.

g. Product Dimensions in this catalogue are subject to changes and are intended for generalreference only. For exact current dimensions, request certified prints from Tsubaki.
