Introduction toTsubaki Roller ChainThis Drive Chain Catalog outlines the important points relating to selection, installation, and maintenance of each TSUBAKI Roller Chain.Make sure to read this catalog before using the chain, and follow the correct selection procedures and method of use. Furthermore,please fully explain matters relating to installation and maintenance to those performing these tasks.Before UseOrdinary TransmissionLifting TransmissionDrive ChainCautionThe horsepower ratingstables in this catalog(excluding SUPER Chain)are for RS Roller Chains andLambda Roller Chains whereconnecting links havingundergone the ring coinprocess and 2-pitch offsetlinks are used.Shuttle TractionPin Gear DriveRoller Chain Safety Use■ Clear the area of all personnel when lifting Roller Chain.■ Install safety equipment to prevent injuries and damage to equipment in the eventof Roller Chain breakage.■ Inspect and replace worn Roller Chain periodically.■ Wear elongation may cause Roller Chain to break and climb up on the sprocket.(Wear life can be extended by periodically applying lubrication, or by using the lubefreeLambda Chain series.)■ Overload may cause Roller Chain to break.(Overload breakage can be avoided through careful selection, considering inertia orby using identically-sized SUPER Roller Chain.)■ Unfavorable environmental conditions such as corrosion may cause eventual RollerChain breakage.(This can be avoided by making sure the chain doesn’t come in contact withcorrosive liquids or steam, etc. Alternatively, the Anti-Corrosive series isrecommended.)■ Correctly install Roller Chain to avoid misalignment or uneven wear and possiblebreakage.A-3

Introduction toTsubaki Roller ChainPower transmission machines use chains, gears, or belts. The table below provides a comparison of typical applications. In general,chain is an economical part of power transmission machines for low speeds and large loads. However, it is also possible to use chainin high-speed conditions like automobile engine camshaft drives. This is accomplished by devising a method of operation and lubrication.Drive ChainGeneral Comparison ofTransmission ElementsSynchronizationTransmissionEfficiencyAnti-ShockRoller Chain Tooth Belt V Belt■■■ ■ ▲▲ ❍ ■▲Spur Gear■■▼Noise/Vibration▲ ■ ■▼SurroundingConditionsAvoid water and dust(Corrosion ResistantRoller Chain is available)Avoid heat, oil,water, and dustAvoid heat, oil,water, and dustAvoid water anddustSpaceWeightHigh SpeedLow LoadLow SpeedHigh LoadLubrication▼ ■ ❍■Compact/Light Weight▲Slightly heavy pulley▼Heavy wide pulley▼ Necessary ■ Unnecessary ■ Unnecessary❍❍Less durability due to lownumber of engaging teeth▼ NecessaryLayout FlexibilityExcess Load onBearing■ ❍ ▲■ ❍ ▼▼■■ Excellent ❍ Good ▲ Fair ▼ PoorFeatures & Points toNote about Roller ChainTransmissionFeatures1. Accommodates large speed reductions/increases (Usually up to 1 : 7)2. Chain can accommodate long shaft center distances (normally less than 4 m), and ismore versatile.3. It is possible to use chain with multiple shafts or drives with both sides of the chain.4. Ease of installation and replacement (easy to cut and connect chains).5. Drive use is possible even when shafts are vertical, as long as the chain receivessupport in short distances between the shafts.6. Standardization of chains under the American National Standards Institute (ANSI), theInternational Standardization Organization (ISO), and the Japanese IndustrialStandards (JIS) allow ease of selection.7. The sprocket diameter for a chain system may be smaller than a belt pulley, whiletransmitting the same torque.8. Sprockets are subject to less wear than gears because sprockets distribute the loadingover their many teeth.9. There is high shock absorbency compared with gears.Points to Note1. Chain has a speed variation, called chordal action, which is caused by the polygonaleffect of the sprockets.(Shock can be reduced under the same speed ratio, by either reducing the chain pitchor increasing the number of sprocket teeth.)2. During transmission, a particular method of lubrication is necessary according to speed.3. Chain wears and elongates, so you need to consider measures for adjusting chainslack.4. Chain is weak when subjected to loads from the side. It needs proper alignment.A-4

Introduction toTsubaki Roller ChainExplanation of Terms1. ANSI Standard Minimum Tensile Strength (Tensile Breakage Strength)This is the Minimum Tensile Strength determined by ANSI. If a roller chain breaks from atensile load below this value, then it does not surpass ANSI standards. In the case ofmulti-strand roller chain, the single strand value is multiplied by the number of strands.2. Average Tensile StrengthThis is a fracture load reading obtained after a long period of actual tensile strength testingof a large number of chain strands. Of course, when any given strand of roller chainfractures, this value may be higher or lower, so it does not represent a guaranteed value.This value differs depending on the manufacturer.3. Minimum Tensile StrengthThis is a minimum value determined by statistical processing at TSUBAKI. If any rollerchain fractures by a tensile load below this value, then it does not surpass the standards.This value differs depending on the manufacturer.Drive ChainMinimum ANSI StandardTensile StrengthTsubaki Minimum Tensile StrengthAve. Tensile StrengthFrequencyTensile StrengthFig. 1 Relationship between three tensile strengths.4. Tensile Strength Testing MethodAs shown in Fig. 2, roller chain with over five links is fixed at both ends by clevises and isstretched until fracture occurs. The type of fracture is indicated by breakage of the rollerchain or failure of its parts (Fig. 3).Fig. 2 Tensile strength testFig. 3 Shape of fractureA-5

Introduction toTsubaki Roller ChainDrive Chain5. Maximum Allowable LoadThe maximum allowable load is the tension load for which a chain is rated to carry inrunning operation. Proper chain tension is critical because excessive tension can causeaccelerated wear/breakage or chain overload and excessive slack can cause roughchain operation and may result in the chain skipping a sprocket tooth.The use of one-pitch offset links reduces the maximum allowable load – it now becomes65% of the maximum allowable load of the main chain.Two-pitch offset links do not change the maximum allowable load of the main chain.In Figure 4 below, the maximum allowable load is indicated by Pmax.Pmax = (Pm + Pa) = 2.2PaWhere a new roller chain with over 5 links receives a repetitive load with a frequency of10 6 .Fig. 4 Summary chart for repetitive loadsLoadTime6. Horsepower Ratings TableRS Roller Chain and SUPER Roller Chain HP rating tables show HP values that allow15,000 hours of operation using a two-shaft drive and 100 pitches of roller chain underconditions 1 - 5 below. The HP ratings table of LAMBDA chain is based on conditions 1- 4 and shows HP rating values when LAMBDA chain is used with two shafts. LambdaChain has more than 14 times the wear elongation of Standard RS Roller Chainoperated without lubrication (#120 and #140 have five times). X-LAMBDA has morethen five times the wear elongation life of Lambda Roller Chain.1) The chains are operated under ordinary conditions where the ambient temperature is–10°C ~ +60°C (+14°F ~ +140°F) and there is no abrasive dust.2) There are no negative effects from corrosive gasses or a high humidity.3) The two transmission shafts are in a horizontal position and the chains are properlyinstalled.4) There is minimal fluctuation in load during transmission.5) The recommended lubrication system and lubricant shown in the HP rating tables isused for RS Roller Chain and SUPER Roller Chain.7. Moment of Inertia (I / J / GD 2 )Moment of Inertia is used to show the degree of inertia in rotational movement, in otherwords, “rotation difficulty”, or “rotation ease.” This is equivalent to the mass (weight) ofthe object being used for straight-line transmission.A-6

Basic StructurePress FitRollerBushingRollerDiameter PitchRoller Link PlateThree Basic DimensionsPitch, Roller Diameter and Widthbetween Roller Link Plates areknown as the “Three BasicDimensions of Roller Chain.”When these three dimensions areidentical, roller chain andsprockets are dimensionallycompatible.* Slip FitWhen the shafts and holes arefitted together, there is acontinuous loose fit. This is a fitwhere the range of tolerance forthe hole is larger than the rangeof tolerance for the shaft (pin orbushing).* Press FitWhen the shafts and holes arefitted together, there is acontinuous interference fit. This isa fit where the range of tolerancefor the hole is smaller than therange of tolerance for the shaft(pin or bushing).A-8Offset PinCotter PinSlip FitSpring clips, cotter pins andspring pins are the parts thatprevent the connecting linkplate from falling off the pin.These parts are critical in orderto maintain the originalstrength of the chain.Connecting Link PlateSpring ClipPin Link PlateSingle StrandPin LinkInner PlateOffset Link Connecting LinkRoller ChainRoller LinkMulti-Strand Pin Link(Two-strand chain shown)• PlateThe plate is the component that bears the tension placed on the chain. Usually this is a repeatedloading, sometimes 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.• PinThe pin is subject to shearing and bending forces transmitted by the plate. At the same time, itforms a load-bearing part, together with the bushing, when the chain flexes during sprocketengagement. Therefore, the pin needs high tensile and shear strength, resistance to bending,and also must have sufficient endurance against shock and wear.• BushingThe bushing is subject to complex forces from all parts, especially from the repetition of shockloads when the chain engages the sprocket. Therefore, the bushing needs extremely high shockresistance. In addition, the bushing 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 the chain engagementwith the sprocket. After engagement, the roller changes its point of contact and balance. It is heldbetween the sprocket teeth and bushing, and moves on the tooth face while receiving acompression load. Therefore, it must be resistant to wear and still have strength against shock,fatigue and compression. RS11 / 15 / 25 / 35 do not have rollers.• Roller LinkTwo bushings are press fit into two roller link plates and rollers are inserted to allow rotationaround the outside of the bushing. This is the same for single strand and multi-strand chain.• Pin Link and Inner PlateThe pin link consists of two pins that have been press fit into two pin link plates. In the case ofmulti-strand roller chain, an inner plate is added to the pin link. The inner plate is slip fit forStandard RS Roller Chain and press fit for SUPER Roller Chain.

Roller Chain Structure2. Assembly PartsRoller Chains are usually made up of a number of connected links in an endless formation, or used by fixing the chain ends, but theneed for connecting links will eventually arise. Although offset links can be used when there are an odd number of links in the roller chain,please use a design that requires an even number of links as much as possible.2.1 Connecting LinksM-type Connecting Links (Formerly: Standard Connecting Link)RS Roller ChainCotter Pin-typeClip-type Cotter Pin-type Multi-strand (2-strand shown) Spring Pin-type (RS240 only) F-type Connecting LinkClipPin Link PlatePinConnecting Link Plate(RC processing)Cotter PinPinPin Link PlateInner PlateConnectingLink PlateSpringPinPin Link PlatePin Pin PinConnecting Link PlateClipPin Link PlateConnectingLink PlateCotter PinDrive ChainChain TypePin & Connecting Link PlateFittingConnecting Link PlateFastening MethodPoints to NoteRS Roller ChainSlip FitPress FitClipCotter PinSpring PinClip / Cotter PinSpring PinT Pin• For multi-strand chain, make sure the plate with ringcoining processing is on the outer most side whenassembling.• Operating speed is indicated by the white area in theHP ratings table.• Make sure to use the chain according to the specifiedapplications on page A-90 and within the speed regionof the colored area in the HP rating tables.Lambda (Λ) RollerChainSUPER Roller ChainSUPER-H Roller ChainULTRA SUPER Roller ChainRS-HT Roller ChainSlip FitPress FitPress FitClipCotter PinSpring PinCotter PinSpring Pin• Can be used in all areas of the HP ratings tablefor Lambda Chain.• Ring coining is carried out on the connecting linkplates.• Please use the exclusive connecting links for eachchain type.• Please use the exclusive connecting link for RS-HTRoller Chain.Heavy Duty RollerChainPress FitT Pin• There are no connecting links, so use connectingpins for assembly.2.2 Offset Links1 Pitch Offset Links (OL)Single strandOffset Link PlateMulti-strand(2-strand shown)2 Pitch Offset Links (2POL)Single Strand Multi-strand (2-strand shown)1 Pitch Offset LinksWhen an OL is used, please allowfor a 20% reduction in HP ratingscompared to that of the main chainand a 35% reduction in MaximumAllowable Load.PinCotter PinOffset Link PlatePlease refer to the dimension tables for roller chain types and sizes suitable for offset links.2.2 Identical maximum allowable load as main chain…(Slip-fit connecting link and two-pitch offset link)Tsubaki ANSI Standard Roller ChainMain chain 100%Slip-fit connecting link 100%Semi Press-fit connecting link 100%Two-pitch offset link 100%One-pitch offset link 65%Pin2 Pitch Offset linksThe pin and offset link plate of a2POL is press fit and is fastenedby a rivet.

V-ClassRoller ChainAn introduction to V-Class ChainTsubaki “V” class roller chains are designed and manufactured for drives used in the most severe conditionswhere high speed and heavy shock load are the norm. Common applications are found in such industries asoil field, mining and logging. These chains are manufactured according to ANSI specifications and also meetAPI specification 7F, oil field chain.“V” class chain features:• Semi-Press Middle Link PlatesMiddle link plates have a shorter pitch than the pin link plates in order to maintain contact with the pin at theouter surface of its holes. This provides and easier cut and assembly without reducing the horsepowerratings of the chain.Drive Chain• Superior Impact ResistanceThe pin surface is carburized and hardened by Tsubaki heat treating techniques for superior impactresistance. This results in greater breaking strength and increased chain impact strength as compared toANSI standard chains.• Greater Fatigue StrengthLink plates are ball drifted after heat treatment for greater fatigue strength. This results in a 30% increasechain life compared to our ANSI standard chains.• Case Hardened PinsCase hardened pins extend the wear life of the chain.• High Speed DurabilityRollers are shot peened after heat treatment to provide superiorwear life and high speed durability.A-35

Energy SeriesOil Field ChainWhen Power CountsHigh productivity, high speeds, high shock loads, and high cyclic loading in the oil field put great demands on roller chain. EnergySeries Chain will keep your operation running smoothly.Drive ChainEngineered for quality and performanceTsubaki builds performance into every Energy Series chain. We start with the highest-quality steel, manufacture all parts to stringenttolerances, and provide the most effective heat- treatment processes to maximize tensile strength and shock load resistance. Thatmeans long-lasting chain in the toughest applications.Z-cotters hold tight, minimizingvibration and maximizing fatiguelife, yet allow easy assembly anddisassembly in the field.A-38

Energy SeriesOil Field ChainStronger pins for longer chain lifeDrilling applications put a lot of stress on pins, and pin wear can cause early chain failure. Energy Series pins are made of specialmaterials, 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.Pitch-compensated link plates maintain maximum strengthEnergy Series link plates have wider waists, putting more steel where you need it to handle shock loads. The addedplate strength creates a rigid link with less deflection under load. Center plates are pitch-compensated, creating acontact fit that allows easy cutting and assembly while maximizing chain strength. The plates hold tighter and sharethe load equally, creating higher fatigue resistance and longer lasting chain.Ballized holes for smoother contactFatigue cracks can start from imperfections in the plate holes. Energy Series chains are manufactured to minimize imperfections. Afterheat treatment, the pitch holes on the side plates are ball drifted to impart residual compressive stress and create extremely smoothhole surfaces, which maximizes fatigue strength.Drive ChainBuilding better bushings and rollersRoller and bushing designs play significant parts in chain life. Every Energy Series chain uses solid rollers, whichare carefully formed from high-grade steel into optimal roundness and then heat treated and shot peened fortoughness and strength. Energy Series features solid bushings for large sizes and precision-formed bushings forsmall sizes. Both types of bushings are fabricated to be the roundest in the industry for smooth, long-lastingoperations.Pre-stressed for performanceAll chains are pre-stressed to ensure uniform load distribution and to minimize initial elongation. The result is better operationimmediately following installation and throughout the life of the chain.Factory-applied hot-dip lube penetrates deeperThe final manufacturing step before chains are shipped is one of the most important. Tsubaki dips each chain in hot lubricant, so itpenetrates 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.Shot-peened link plates addfatigue resistance.Ballized holes for tighter tolerancesand a smoother fit.A-39

SpeedMasterRoller ChainSpeedMaster Chain from Tsubaki is the answer for high-speed applications. SpeedMaster features carbon through-hardened plates.The pins are made of a specially treated alloy material. The surface of the pin is extra hard – improving wear resistance. The pins arequad riveted to better resist side force impact. The chain features a greater contact area between pin and bushing which results in lesscontact wear pressure and longer wear life. Shepherd’s crook style cotter pins make for easy assembly of connecting links. Tsubaki’spatented ring coining process generates unsurpassed connecting link strength. Depending on speed of the application and operatingconditions (e.g. lubrication), users can expect between 2 and 6 times greater wear life compared to ANSI Standard RS Roller Chain.Drive Chain2POLTQuad-rivetedL1L1hHTφDφRL2WQuad-rivetedL2CL1L1PPAll dimensions in inches unless otherwise stated.PitchPRollerDia.RWidthBetweenInner LinkPlatesWThicknessTLink Plate PinHeightHHeighthDia.DLengthL 1 + L 2LengthL 1LengthL 2TransversePitchCAverageTensileStrength(lbs.)MaximumAllowableLoad(lbs.)Approx.Weight(lbs./ft.)Chain NumberSingle StrandRS60SM 0.750 0.469 0.500 0.094 0.713 0.614 0.235 1.087 0.506 0.581 - 9,900 1,980 1.03 160RS80SM 1.000 0.625 0.625 0.126 0.949 0.819 0.313 1.398 0.640 0.758 - 17,600 3,300 1.78 120RS100SM 1.250 0.750 0.750 0.157 1.185 1.024 0.376 1.677 0.778 0.900 - 27,200 5,060 2.67 96RS120SM 1.500 0.875 1.000 0.189 1.425 1.228 0.437 2.118 0.980 1.138 - 39,600 6,820 3.97 80RS140SM 1.750 1.000 1.000 0.220 1.661 1.433 0.500 2.307 1.059 1.248 - 52,800 9,020 5.02 68Double StrandRS60SM-2 0.750 0.469 0.500 0.094 0.713 0.614 0.235 1.988 0.955 1.033 0.898 19,800 3,360 2.04 160RS80SM-2 1.000 0.625 0.625 0.126 0.949 0.819 0.313 2.551 1.217 1.335 1.154 35,200 5,610 3.53 120RS100SM-2 1.250 0.750 0.750 0.157 1.185 1.024 0.376 3.091 1.484 1.606 1.409 47,400 8,602 5.26 96RS120SM-2 1.500 0.875 1.000 0.189 1.425 1.228 0.437 3.906 1.874 2.031 1.787 79,200 11,590 7.84 80RS140SM-2 1.750 1.000 1.000 0.220 1.661 1.433 0.500 4.232 2.022 2.211 1.925 105,600 15,334 9.94 68Note: Horsepower ratings for SpeedMaster chain are same as for identical size of Tsubaki RS Standard ANSI roller chainNumberof linksper10 feetA-45

Heavy Duty Roller ChainAn introduction to Heavy Duty and SUPER Series ChainDrive ChainTsubaki offers Heavy Duty and SUPER Series roller chains for applications that exceed the capabilities of Tsubaki ANSI standard RSRoller Chain. These heavy duty applications include the following:1. Severe operating conditions such as heavy shock loads.2. Where space to put the chain is limited. A Heavy Duty chain will often deliver the same tensile strength of a larger size ofStandard RS Roller Chain.3. Operating conditions that require higher horsepower ratings, maximum allowable load and tensile strength.H (Heavy) Series:H (Heavy) Series roller chain differs from ANSI (RS) standard series roller chain only in the extra thickness of the link plates. Theselink plates have the same thickness as the link plates of the next larger size of ANSI standard series. The thicker link plates provide(approximately 10%) greater capacity for absorbing shock loads. Through hardened pins are used up to size 140 chain. Above size140, the pins are case hardened. H series chains are especially suited to situations where the load is heavy and operating speeds arelow (up to 165 ft./sec.), or where operating conditions are severe.SUPER Series:The dimensions of this series are identical to those of ANSI (RS) standard series roller chain. The special design of the SUPER serieslink plates delivers exceptional performance. The pitch holes are critically formed and drifted to improve their allowable tension by25%-30%; and the pins are through hardened for greater shock resistance. SUPER series chains offer horsepower ratings 30%greater than the equivalent size ANSI standard chain. SUPER series chains can be used to replace the next larger size of ANSIstandard chain, making it ideal for applications where space is limited.HT Series:HT series chains provide a (15%-30%) greater ultimate tensile strength over ANSI standard roller chain by using through hardenedpins and link plates of the next larger ANSI standard chain sizes. HT Series chains also provide a greater shock load resistance.The dimensions of the chain are identical to the H Series (above). HT Series chains also provide a greater shock load resistance andare best suited for low operating speeds – up to 165 ft./sec.SUPER-H Series:The thickness of SUPER-H series link plates is the same as the next larger size of SUPER series chain. The pins are also throughhardened which provides a 13% greater ultimate tensile strength and 6% greater allowable tension than SUPER series chain.SUPER-H series chains can be used to replace the next largest size of ANSI standard chain, making it ideal for applications wherespace is limited. It is best suited for low speed operating conditions – up to 165 ft./sec.ULTRA SUPER Series:ULTRA SUPER series offer longer wear life, greater allowable load, higher tensile strength than any other Tsubaki roller chain. Thischain is well suited for applications where there are space limitations. The heavy duty construction of the ULTRA SUPER serieschains allows it to replace an (up to) two sizes larger ANSI standard roller chain.

British Standard/DINRoller ChainDrive ChainIntroduction to Tsubaki British Standard/DIN Roller ChainTsubaki British Standard/DIN roller chains are manufactured to the following standards: International Standards Organization(ISO 606), British Standards Institution (BS 228) and Deutsches Institut für Normung (DIN 8187).Tsubaki produces British Standard/DIN roller chain in a variety of sizes (now including RS05B and RS48B) and materials(carbon steel, lube-free Lambda, stainless steel and nickel plated). These chains are ideal for use on equipment that has beenimported into Canada or on new machinery that is made in Canada but destined for export.Features of Tsubaki British Standard/DIN roller chain include:• Easy disassembly (cutting) on sizes RS08B to RS16B. Users can easily extract the pin on-site, with a standard screwtype chain cutter.• Ring coining - a process unique to Tsubaki whereby the connecting link is made as strong as the rest of the links in thechain. The ring coining process creates plastic deformation around the pinhole on the link plates of the chain. Thisgenerates residual stress around the deformed area, which boosts the transmission capacity of the connecting links to thesame level as the chain itself.• Solid rollers, bushes and link plates, all of which are shot-peened - a process that work hardens the surface of thesecomponents, improving their durability at high speed and increasing fatigue strength.• Center sink design of the rivet head - the result of years of experience in manufacturing marine diesel chain atTsubaki. The benefit of the center sink pin design is that notches on the rivet head indicate line of riveting and easyidentification in the case of pin rotation caused by overload conditions.• Wider link plate design - improving the fatigue strength.• Chain is pre-stressed after manufacture to ensure that all components are properly seated. This reduces the need forinitial chain adjustment and has also improved the length tolerance.A-61

British Standard/DIN ChainDrive SelectionSELECTION PROCEDURENumber of Pitches of ChainDrive Chain1) The following factors must be considered when selecting rollerchains for transmission needs.• The power to be transmitted.• The speed and the diameters of the driving shaft and thedriven shaft.• The distance between the centers of the shafts.2) Use Table I to obtain the “service factor”.(The “Service Factor” table refers to the type of machine andsource of power.)3) Multiply the HP value by the service factor to obtain the designHP value.4) Use Table III page A-67 to obtain the appropriate chain numberand the number of teeth of the small sprocket by referring tothe number of revolutions of the high speed shaft (the drivingshaft when the speed is reduced; the driven shaft when thespeed is increased) and the design HP value. For a smootherchain drive, a smaller pitch chain is suggested. If a singlestrand chain does not satisfy the transmission requirements,use a multi-strand chain. If the distance between the shafts andthe diameter of the sprockets must be relatively small due tospace considerations, a multiple strand roller chain with asmaller pitch may be used.5) After determining the number of teeth for the small sprockets,confirm if the sprocket will meet the shaft diameterrequirements.N 2 –N 1L=N 1 +N 2+2C+6.282 CAny fraction of L is counted as one pitchCenter Distance in Pitches√18C= 2L–N 1 –N 2( ) 2+ (2L–N 1 –N 2 ) 2 – (N 2 –N 1 ) 2L: Number of pitches of chainN1: Number of teeth (small sprocket)N2: Number of teeth (large sprocket)C: Center distance in pitchesChain SpeedS=P • N • n(ft./min.)12S: Chain speed (ft./min.)P: Chain pitch (inch)N: Number of teeth of sprocketn: rpm of the sprocketChain Tension from HP{89.86}6) The number of teeth for the large sprocket is determined bymultiplying the number of teeth for the small sprocket by thespeed ratio. While it is preferable that the number of teeth forthe small sprocket be greater than 15, it is suggested that thenumber of teeth for the large sprocket not exceed 120. Byreducing the number of teeth for the small sprocket the numberof teeth for the large sprocket can also be reduced.T=33,000 X HP(lbs.)ST: Chain tension (lbs.)Table II: Multiple Strand FactorNumber of RollerChain StrandMultiple-StrandFactorDouble Strand 1.7Triple Strand2.5Table I: Service FactorType of ImpactSmoothMachinesBelt conveyors with small load fluctuation, chain conveyors,centrifugal blowers, ordinary textile machines, ordinary machineswith small load fluctuation.ElectricMotor orTurbine1.0Source of PowerInternal Combustion EngineWith hydraulic Without hydraulicdrivedrive1.01.2Some impactCentrifugal compressors, marine engines, conveyors with some loadfluctuation, automatic furnaces, dryers, pulverizers, general machinetools, compressors, general work machines, general paper mills.1.31.21.4Large impactPresses, construction or mining machines, vibration machines, oil wellrigs, rubber mixers, general machines with reverse or impact load.1.51.41.7A-66

The ambient temperature range isbetween 15°F and 140°F. They are not to beused in an atmosphere where abrasive dust orcorrosive gas is present or when the humidity isexceptionally high.2) The two transmission shafts are in a horizontalposition and the chains are properly installed.3) The suggested lubrication system shown onTable IV is used.4) The load does not change significantly duringtransmission.The “Service Factors” given in Table I are usedwhen the chains are used under variousoperating conditions. The load conditions willaffect the life of the chain. The increase in thehorsepower rating of multiple-strand rollerchains cannot be calculated simply bymultiplying the horse-power rating of one strandby the total number of strands, since the loadon each strand is not exactly the same. In orderChain Speed (ft./min.)Table IV: Chain Speed andLubrication SystemChain No.to estimate the service life of a multiplestrandchain, the “Multiple-StrandFactor” given in Table II must be used.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 (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 inches24 inches).Step 4 Use Table IV and determine thelubrication method.Chain speed (S) = P • N • n12= 1 X 600 X 17 = 850 ft./min.12System B is suggested.Step 5 Obtain the number of pitches ofchain (L).N 2 - N 2(1)= N1 + N2 + 2C +6.282 C251 - 17( )= 51 + 17 + 2 X 19 +6.282 1 191= 73.35 74 linksA-67

Anti-CorrosiveRoller ChainAn Introduction toTsubaki Anti-Corrosive Roller ChainsDrive ChainNP Nickel Plated Roller ChainNP is an RS Roller chain that has been plated with nickel. NP Chain has an attractive appearance and light corrosion resistance thatmakes it suitable for outdoor conditions where it is exposed to water. The maximum allowable load of nickel plated chain is 15% lessthan the equivalent RS roller chain.Nickel plated roller chain should not be used where the chain comes into direct contact with food products. Nor should it be usedwhere the nickel plated coating flakes may mix with and or contaminate food products. In non-food applications, a cover should beused where the coating flakes or wear dust may pose a problem.Nickel plated roller chain has magnetic properties.Working temperature range: +14˚F ˜ +140˚F.Ultra WP Roller ChainUltra WP is an RS Roller Chain that has undergone a special surface treatment (clips are type 301 stainless steel). This chain is morecorrosion-resistant in wet environments than NP chain, and is suitable for use in environments exposed to salt-water. The horsepowerratings are the same as RS Roller chain. Ultra WP roller chain has magnetic properties.Working temperature range: -22˚F ˜ +302˚FNeptune Roller ChainNeptune is RS Roller Chain that has been both zinc galvanized and specially treated on the surface with a coating that togetherprovide a double plated effect. (The surface treatment is applied to each individual part of the chain before it is assembled). Thishighly durable chain has superior corrosion resistance to salt-water and all types of weather. Tensile strength and maximum allowableload are identical to carbon steel RS Roller Chain.Neptune roller chain should not be used where the chain comes into direct contact with food products. In non-food applications, acover should be used where the coating flakes or where dust may pose a problem.Working temperature range: +14˚F ˜ +140˚F.SS Stainless Steel Roller ChainStainless Roller Chain is composed of type 304 stainless steel (clips are type 301). This chain is more corrosion resistant than RSRoller Chain, NP Roller Chain and Ultra WP Roller Chain. It can be used in special environments such as corrosive conditionsunderwater and in acids/alkalis. It is non-magnetic, though it may have some magnetic properties at low operating temperatures.Working temperature range: -4˚F ˜ +752˚F.NS Stainless Steel Roller ChainThis is a roller chain made from type 316 stainless steel (note that clips on the RS25NS size use type 301). The NS Stainless SteelRoller chain has the greatest corrosion resistant properties of all of Tsubaki’s stainless steel roller chain products. It has the highestresistance to extreme temperatures and has very low magnetic permeability.Working temperature range: -4˚F ˜ +752˚FA-68

Anti-CorrosiveRoller ChainAn Introduction toTsubaki Anti-Corrosive Roller ChainsAS Stainless Steel Roller ChainThis roller chain uses heat-treated hardened stainless steel (type 600) for the pins and rollers. The link plates and bushings aremade from type 304 stainless steel (clips are type 301). AS series chains are an excellent choice for drives requiring both corrosionresistance and high load capacity. Maximum allowable load is 50% greater than “SS” series Stainless Steel Roller Chain. Note thattype 600 stainless steel has magnetic properties.Working temperature range: -4˚F ˜ +752˚FPC Poly Steel ChainPoly-steel chain requires no lubrication, has greater wear resistance and is about 50% lighter than RS Roller Chain. This chain issuitable for maintenance free and sanitary environments. Poly-steel chain consists of an engineering plastic inner link and 304 typestainless steel pins and outer link plates. This chain can be used for both conveying and driving applications. It can accommodatestandard attachments.Working temperature range: -10˚F ˜ +176˚FFor more details on poly steel chains - including diagrams and specifications - please refer to the separate Plastic Roller Chainssection in this catalogue.Drive ChainTI Titanium Roller ChainTI chains are extremely lightweight (50% of the weight of carbon steel) and are made completely of titanium, making it both nonmagneticand highly corrosion resistant.Working temperature range: -4˚F ˜ +752˚FA-69

Leaf ChainDrive ChainAn Introduction to Tsubaki Leaf ChainLeaf Chain is the most simple of steel chains, consisting only of link plates and pins. This chain generally has greater tensilestrength than roller chains and runs over sheaves rather than sprockets. They are suitable for hanging, balancing or motiontransmitting applications. Leaf chains are often used as counterweight chains for machine tools, elevator and oven doors, forklift truck masts, spinning frames and similar lifting or balancing applications. Plates are connected by pins and hold the tensionloaded onto the chain. The pins are designed to resist the shear force from tension loading applied by the link plates. The pinsare also designed to withstand abrasion from the middle plate holes when the chain articulates.AL type: Plate configuration and thickness are the same as ANSI Standard RS Roller Chain. Pin diameter is almost the sameas ANSI Standard RS Roller Chain.BL type: The outside dimensions of the plates are the same as ANSI Standard RS Roller Chain inner plates of the same pitch.The plate thickness is the same as one size up Tsubaki RS Roller Chain. BL series can in most instances replace the older ALseries leaf chains – consult Tsubaki Technical Support for interchange information.A-78

Leaf ChainLEAF CHAIN SELECTION GUIDELINES1. Obtain the following factors that are specific to your application:• Chain Speed (Operation Speed)• Number of operations (reciprocations) per day• Working load (Including: attachment weight, inertia force and impact force)When the chain speed exceeds 100 ft./min, and/or, the number of operations (reciprocations) exceeds 1,000 times/day, wearproblems may happen. In these cases, Tsubaki RS Roller Chain is recommended - not leaf chain.Drive Chain2. Determine leaf chain type.• BL type is generally recommended.• AL type can be used when the application has no impact load and wear problem.(Number of strokes does not exceed 100 times/day)3. Determine Chain Size:Working load X Service Factor X Safety Factor < Minimum Tensile Strength(Table 1) (Table 2)4. If the chain is operated with a lesser safety factor than the one shown in Table 2, the pin may rotate and lead to chain breakage.Even if the chain is operated with the proper safety factor, the lack of lubricant may cause pin rotation, so the chain must beperiodically lubricated.5. In case the safety factor and/or chain selection are subject to some official law and/or regulation, compare the outcomes of boththe specified selection and this selection, and select the safer of the two.Table 1 Service factorImpact Applications Service FactorSmooth TransitionStart and stop are smooth.Load fluctuation is low (eg. suspension of counterweights).1.0Small Impact Frequent start, stop, load fluctuation and reversing (eg. fork lift). 1.3Heavy ImpactHeavy and rapid start, stop and load fluctuations are required.(eg.

Specialty ChainAn Introduction to Tsubaki Specialty ChainTsubaki is the world’s leader in providing specialty chains for the most demanding applications. In addition toindustry leading Made-to-Order capabilities, Tsubaki offers a number of “standard” specialty chains.Drive Chain• Low Noise (SN) Chain — Uses uniquely structured spring rollers which absorbs the force of impact betweenchain and sprocket. The result is lower noise levels.• FX Chain — Increased clearance between pins and bushings allows for added chain flexibility with excellentdurability.• Rollerless Chain — Designed and manufactured to withstand continued wearing.• Wrench Chain — Extra long pins serve as tension linkages to provide a secure hold for pipe wrenches.• Laminated Block Chain — Manufactured with 304 stainless steel, it directly replaces solid block chain in lightload, low speed applications.• KT Cold Resistant Chain — This chain can be used in colder temperatures than RS Roller Chain while offeringidentical horsepower ratings.A-84

Specialty ChainLow Noise (SN)Specialty ChainTsubaki’s uniquely structured spring rollers are used for the chain rollers. When Tsubaki’s SN Roller Chain engages with the sprocket,the spring roller deforms and absorbs the force of the impact. The lower impact force reduces impact noise between chain andsprocket resulting in lower noise levels. Compared with Tsubaki’s standard RS Roller Chain (pre-lubricated), noise levels of SN RollerChain are 6 - 8 dB lower. (In-house comparison testing).

Service FactorsTsubaki offers simplex, duplex and triplex chains in RF06B toRS40B of BS/DIN European standard. In ANSI standard, up to6 strands are available as standard items from RS40 to RS240and up to triplex for RS25 and RS35. In multiple strand chaindrives, the load is unequal across the width of the chain, so thetransmission capability of multiple strand chain is calculatedusing multiple strand factors shown in the table below.Table 1 : Multi-strand factorNo. of strands2 strands3 strands4 strands5 strands6 strandsService factor K sThe chain’s transmission capacity is affected if there is frequentload fluctuation.

Example: Single strand chain,design kW = 5 kW (6.7 hp)(1) Assume that the speed of thesmall sprocket is 100 r/min.Judging from the intersecting pointof design kW value of 5 kW or 6.7hp (vertical axis) and the speedvalue of 100 r/min (horizontalaxis), RS80 and a sprocket withbetween 13 and 18 teeth would beappropriate. Therefore, based onthe position of the intersection, wecan see that a 14T sprocket canbe used.(2) Assume that the speed of thesmall sprocket is 300 r/min.Following the same procedureshown in the above example,RS60 and a sprocket with lessthan 13 teeth or RS50 and asprocket with more than 18 teethwould be appropriate. This table isused for tentative selections only.The power ratings tables shouldbe used to confirm the chainsizes.(3) When the chain speed is less than164 ft./min., it is more economicalto select your RS Roller Chain byslow speed selection.(4) Allow for a 20% drop in the powerrating values shown in the designpower ratings chart (Table 6) when1-pitch offset links are used.(5) A 4-pitch offset link is available forSUPER Roller Chain and thepower ratings are the same as inTable 7.

However, if the number ofteeth for the large sprocket exceeds 120 as aresult, then this is not favorable. When thishappens, reduce the number of teeth for the smallsprocket; although, it is recommended to usemore than 13 teeth.Procedure 7If possible, try to avoid using an offset link whenusing an odd number of links. Instead, try adjustingthe distance between the shafts until an even numberof links is attained.Procedure 7Calculate the chain length L(number of links)Procedure 8Determine the method oflubrication from number ofrevolutions of the smallsprocketEndA-96

Drive Chain SelectionExample based on the general selectionProcedure 1: Data requiredMachine used: AgitatorType of shock: Smooth transmissionSource of power: MotorRated power: 50 HPHigh speed shaft: Shaft diameter 1 7/8” 750 r/min.Low speed shaft: Shaft diameter 2 3/8” 250 r/min.Distance between shafts : 9”Space limitation : 20”MotorAgitatorDrive ChainProcedure 2: Use Table 2 to determine the service factorService factor K s = 1.0Procedure 3: Obtain design power 50 HP x 1.0 = 50 HPProcedure 4, 5: Determine the chain and the number ofteeth for the sprocket. Based on the fact that the number ofrevolutions of the high speed shaft is 750 r/min and thedesign HP is 50 HP, we can find the chain number and thenumber of teeth of the small sprocket.1. According to the power rating table, the best choice wouldnormally be a single strand of RS80-17 teeth. Since thespeed ratio is 1/3 (250/750 r/min.), the necessary numberof sprocket teeth would be 17 for the small sprocket and51 for the large sprocket. However, as the outsidediameters are 5.9” for 17 teeth and 16.8” for 51 teeth, itexceeds the space limitation of 20”. (5.9” + 16.8” > 20”)Therefore, these sprockets are not suitable.2. As a single strand chain is not suitable, a double-strandRS60-2, 22 and 66 teeth would be possible. But thiscombination is not suitable due to the space limitationagain (5.7” + 16.2” > 20”).3. For triple strand, RS60-3, 15 and 45 teeth would bepossible. The sprocket’s diameters are 3.9” and 11.2”respectively, the sum of which is less than 20”. The HPrating of a 15 tooth sprocket for the RS60-3 should beconfirmed by the HP rating for the RS60. The HP rating ofa 15 tooth sprocket is 18.9 HP at 700 r/min, and 21.3 HPat 800 r/min. The HP rating at 750 r/min is about 20 HP.Since 20 HP is for a single strand chain, the horsepowerrating must be multiplied by a multi-strand factor of 2.5 fora triple strand (refer to Table 1). Therefore, the HP ratingof RS60-3, 15 teeth at 750 r/min. is 50 HP (20 x 2.5 = 50)4. This 50 hp rating satisfies the design HP rating.Procedure 6: Confirm the shaft diameter.The shaft diameter is confirmed by the dimension table. Themax. shaft diameter of RS60-15T is 1 7/8” and can be usedfor the shaft diameter of 1 7/8”. The maximum shaft diameterfor RS60-3-45T is 2.5” and so satisfies our shaft diameter of2.36”. The outside diameter for both sprockets is 3.5” and11.2” respectively and fits within the prescribed space.Procedure 7: Determine the distance between shaftsIf the center distance between shafts is 8.66”, from theformula the chain length of L is as follows:In order to have an even number of links, we raise the valuebelow the decimal point to an integer and get 56 links.L =((45 +15 + 2 ×920.75(Procedure 8: Confirm the method of lubricationFrom the power rating table, lubrication method B is selectedfor the small sprocket of size RS60-3-15 T at 750 r/min.Lubrication is necessary by oil bath lubrication or by slingerdisc.(+(( ) 245 – 156.2890.75(= 55.9A-97

The temperature limit for use is decided by the temperature of thechain itself. If your operation runs at temperatures higher than +400°C (+752°F), consult the manufacturer before making your chainselection. Note that the chain cannot be used in temperatures in excess of +700°C (+1,292°F). The chain speed should be less than160 ft/min for selection by temperature.Changes and important points regarding high temperature environments:1) In order to prevent poor articulation and poor roller rotation from heat expansion, clearances in each part need to be changed.2) It is possible that the chain will break (creep rupture) at lower loads when the temperature becomes higher.10. Special Selection Method for Corrosion-Resistant Roller ChainSlow speed selection (selection by max. allowable load) is employed for Corrosion-Resistant Roller Chain Selection.1) The maximum allowable load of some Corrosion-Resistant Roller Chain is lower than that of Standard RS Roller Chain.2) Avoid using offset links wherever possible.3) The chain speed should be less than 160 ft/min for selections made in “Special Selection Method.”4) Refer to the following page when substances such as acids, alkalis or chemicals come into contact with the chain.5) Selection formulaMax. chain working load×Service factorK s×Speed factor Sprocket teeth factor×

Roller ChainInstallation & Maintenance1. How to Cut Roller ChainIf the chain you purchased is either a unit length (10 ft.) or on areel, it is necessary for you to cut the chain to the necessarylength.How to cut Roller Chain1.1 Using a chain vice and punch1) For riveted type roller chain, grind down one end of the outerlink plate’s two pins (same side) to the surface of the link plate.Be careful of the chain overheating during the grindingprocess. In the case of Lambda Chain, grinding should becarried out slowly so as not to overheat the bushings. PolySteel Chain has no rivets and so this process is not necessary.2) Remove the cotter pin for cotter pin type roller chain.The riveted portion of the pin is ground( down to the surface of the link plate. )Fig. 1 Rivet-type roller chain3) As shown in the photo, put the roller chain into the groove ofthe chain vice (refer to Chain Tools section) and tighten thevice to secure the roller to be disassembled.(1) Please follow steps 1.3 and 1.4 for Poly Steel Chain andLambda Chain.(2) For multi-strand SUPER Roller Chain, put the far end rollerinto the groove of the chain vice.Fig. 3 Setting the roller chainin the chain vice.Using a chain vice and punchUsing a chain breakerFig. 2 Grinding the pin endsSetting SUPER RollerChain0Safety Precautions(1) Make sure to use a grinder when grinding the rivetedportion of one end of the rivet-type pin. If it is extractedwithout being ground first, more time and effort will bespent, or the chain will be damaged.(2) Do not reuse any removed parts.1.2 Using a chain breaker1) For riveted type roller chain, grind down one end of the outerlink plate’s two pins (same side) to the surface of the link plate.(Same as 1.1) Remove thecotter pin for cotter pintype roller chain.2) Remove the two pins fromthe same outer link plate.Check to make sure thatthe bushing where the pinwas removed has notcome loose or deformed.Do not use loose ordeformed parts.1.3 How to cut Poly SteelFig. 5 Cutting chain using achain breaker0Safety Precautions(1) A chain breaker (see the chain tools section) is a toolmade for cutting chain, and can cut roller chain that is seton a machine. In this case, it is necessary beforehand tosupport the load on the roller chain and the weight of theroller chain itself to prevent it from falling after being cut.(2) Do not reuse any removed parts.Chain1) Support the outer link plate of the chain in the cradle and pushdown on the pinhead with the exclusive punch. Then lightly hitthe head of the punch using a hammer.2) Avoid using excess force on the engineering plastic part, asthere is a possibility of causing damage.Drive Chain4) Place the appropriate primary punch (refer to Chain Toolssection), according to chain size, on the head of the groundpin, and then hit the head ofthe primary punch with ahammer. Make sure to hit thepins alternately to ensure thepins are removed evenly andat the same time. Continue totap the pin until just beforethe pin is removed from theouter link plate.5) Use the secondary punch toremove the pin completelyfrom the outer link plate.Check to make sure that thebushing where the pin wasPrimary punchOuter link plateFig. 4 Tapping the pin withthe primary punch.removed has not come loose or been deformed. Do not useloose or deformed parts.ViceCradleFig. 6 Poly Steel Chain set in the cradleExclusivepunchCradleFig. 7 Cutting Poly Steel ChainA-107

Roller ChainInstallation & MaintenanceDrive Chain1.4 How to cut Lambda Chain1) Support the chain with a chain vice or something similar, andgrind down one end of the outer link plate’s two pins (sameside) to the surface of the link plate. Be careful that the chaindoes not overheat during the grinding process. Grinding shouldbe carried out slowly so as not to overheat the bushings.2) The chain is then cut using an exclusive cradle (refer to ChainTools section) and an RS Roller Chain punch. Important pointsfor cutting are outlined in 4) and 5) in 1.1. However, please usean exclusive cradle instead of a vice.3) When removing the pins with a punch, alternately hit the pins.Take extra care not to remove or cause any damage to thebushing. Make sure not to use this part if the bushing has comeloose or been damaged.2. How to Connect Roller Chain2.1 When connecting chain on sprocket teethWhen connecting or disconnecting roller chain, it is convenient touse the sprocket teeth. Carry out the following steps.1) Wind the chain around one of the sprockets such that both endsof the chain are facing each other on the sprocket.2) Apply oil and grease to the connecting link.3) Insert the connecting link into the two end links of the chain.4) Insert the connecting link plate of the connecting link and fastenthe plate using the clips/cotter pins or spring clips supplied.5) When using a press-fit connecting link or semi-press-fitconnecting link, insertthe connecting linkplate by tapping it witha hammer until itmoves into position.Then fasten it usingthe clips/cotter pins orspring clips supplied.6) When using thesprocket teeth toconnect the chain,take care not todamage the teeth, Fig. 8 Connecting on a sprocketparticularly whenusing a cast iron sprocket.2.2 When connecting between shaftsIf the sprocket cannot be used due to the layout, please carry outthe following steps.1) Wind the chainaround the sprocketsand pull the chainends together using achain puller (refer toChain Tools section)or wire.2) Apply oil and greaseto the connecting link.3) Insert the connectinglink into the two endlinks of the chain. Fig. 9 Connecting between shafts4) Insert the connecting link plate of the connecting link andfasten the plate using the clips/cotter pins or spring pinssupplied.2.3 Spring Clips and Cotter Pins1) Spring ClipsSpring Clips are used for small size roller chain (under RS60)connecting links. When connecting the chain, the clip shouldbe inserted securely into the slot ofthe pin on the connecting link afterthe connecting plate has beeninserted on the pin. If the legs ofthe clips are spread too far theywill not catch properly and will falloff during operation of the chain.Care should be taken when insertingthem. The direction in which the clipis installed is generally opposite tothe direction of travel for the chain asshown in Fig.10.Directionof travelFig. 10 Direction inwhich the clipis installed2) Cotter PinsTSUBAKI’s cotter pins are heat treated. The legs of the cotterpins should be bent to an angle of approx. 60 degrees. Cotterpins should not be reused, and commercially available cotterpins other than those produced by TSUBAKI should beavoided.Cotter pinT-pinZ-pinFig. 11 Angle of legs for cotter pins0Safety Precautions(1) Avoid using offset links wherever possible by varying thecenter distance between shafts or using an idler.(2) In the case of pins and connecting link plate holes beingpress-fit or semi-press-fit type connecting links, avoidwidening the connecting link plate hole or narrowing thepin diameter. Doing so will result in a reduction in rollerchain strength.(3) The outer link of cotter pin type roller chain can be usedas a substitute for the connecting link. However, due tothe press fit connection, the outer link plate must becarefully driven onto the pin parallel to the connecting link.If the connecting link plate is installed without due care toparallelism, chain damage or increased wear may result.(4) Do not reuse press fit type link plates that have beendetached.A-108

Roller ChainInstallation & Maintenance3. RS Roller Chain LubricationOne of the most important factors in getting the best possible performance from your roller chain is proper lubrication.Following are some important points to remember:1) The main purpose of lubricating and greasing is to limit wear elongation and prevent corrosion of the chain. Wear elongation arisesfrom wear between the pin and bushing when the chain articulates.2) TSUBAKI roller chain is pre-lubricated before packing. This helps to limit the amount of wear elongation during startup.3) Use of detergents or solvents to clean chain will remove lubricant.3.1 Lubrication Position1) Since chain elongation is caused by wear between the pins and bushings, these parts must be well lubricated.2) The clearance between the outer link plate and the inner link plate on the slack side of the chain should be lubricated with oil. Theclearance between the bushing and the roller should also be done at the same time.Drive ChainFig. 12 Lubrication Position3.2 Lubrication for Lifting chain1) Although there is generally no slack side, lubrication must be done while the chain is not loaded.2) For roller chain that does not articulate, grease should be applied thickly to prevent corrosion. The end fitting connection should alsobe well lubricated, even if there is no movement.3) Since there is a possibility that rain or snow may cause loss of lubrication or corrosion from outdoor use, a protective cover shouldbe attached to the chain.3.3 Recommended Lubrication1) SAE No.Table 1Lubricating SystemA I · A II · BAmbient Temperature –10°C - 0°C 0°C - +40°C +40°C - +50°C +50°C - +60°CChain No.(+14°F - +32°F) (+32°F - +104°F) (+104°F - +122°F) (+122°F - +140°F)RS50 and under SAE10W SAE20 SAE30 SAE40RS60 · 80RS100SAE20 SAE30 SAE40RS120 and over SAE30 SAE40 SAE50–10°C - 0°C(+14°F - +32°F)0°C - +40°C(+32°F - +104°F)+40°C - +50°C(+104°F - +122°F)2) Lubrication in high or low temperature conditions.Please consult Tsubaki Technical Support for more information on lubrication in high or low temperature conditions.SAE50+50°C - +60°C(+122°F - +140°F)SAE10W SAE20 SAE30 SAE40SAE20 SAE30 SAE40CSAE50A-109

Oil from the oilcup is supplied by dripfeeding.Oil should be applied at fixed intervals, usuallyabout every eight hours, or as often as necessaryto prevent the bearing areas from becoming dry.* An automatic lubricator is also available for yourconvenience. Please consult Tsubaki for moredetails.Apply about 5 - 20 drops of oil per minute forevery strand of chain. Actual quantity depends onthe chain speed.IIOil Bath LubricationThe chain is installed ina leak-free casing.Chain should be submerged in oil 1/4” to 1/2”. Ifthe oil depth “h” is too large, the composition ofthe oil may change due to heat generated (morethan +80°C/+176°F) and lose some of itseffectiveness.BLubrication by Slinger DiscInstall the slinger disc in aleak-free oil casing. Oil issplashed on the chain.The circumference speedshould be at least 656ft./min If the width of thechain is greater than 4.9”,attach slinger discs toboth sides.The bottom of the slinger disc should be loweredto a position 1” from the surface of the oil. Thechain should not pass through the oil.CLubrication using a PumpUse a leak-free casing.A pump is used tocirculate the oil, which isthen cooled.

Any scratches or reddish-brown color appearing on theirsurfaces indicates that the system is not being adequately lubricated.A-110

Roller ChainInstallation & Maintenance4. RS Roller Chain Installation and Layout4.1 Speed Ratio and Chain LapThe speed ratio of roller chain can range up to 7 : 1 undernormal operating conditions. However, a speed ratio of 10 : 1 ispossible if the speed is very slow. Chain lap on the smallsprocket must be at least 120° and at least 90° in the case oflifting chain.˚˚In the following cases, the slack should be about 2% of thespan.(1) Vertical drive or close to vertical drive (tensioner isrequired)(2) Center distance between two shafts is greater than 1 m.Drive ChainFig. 14 Amount of chain slack˚4.2 Distance between shaftsSprockets can be separated by any distance as long as theirteeth do not touch. Optimum distance is 30 to 50 times the pitchof the chain. However, the distance should be up to 20 times thepitch of the chain when there is a fluctuating load.4.3 Amount of Slack1) It is not necessary to apply initial tension to roller chain likeV/horizontal belt drives. In general, roller chain is used with asuitable amount of slack. If roller chain is stretched too much,the oil film between the pin and bushing will be torn anddamage to the roller chain and shafts will be accelerated. Onthe other hand, too much slack will cause the roller chain tovibrate, or ride up on the sprocket teeth resulting in damage toboth the roller chain and the sprocket.˚Fig. 13 Chain Lap(3) Chain is operated under heavy load and frequent starts.(4) Chain drive is suddenly reversed.3) Roller chain tends to slightly elongate (about 0.05%) in thefirst few dozen hours of use. This elongation causesexcess slack, so the amount of slack needs to beadjusted. Use a tensioner if the system has been designedfor it. If a tensioner is unsuitable, adjust the slack bymoving the shafts.4.4 Horizontal Precision and Parallelism of the ShaftsInstallation accuracy of the sprockets greatly affects thesmoothness of the roller chain drive and also influences thewear life of the roller chain. Make sure to carry out the followingimportant steps correctly.1) Check the horizontal specification with a level. Adjust theshafts so that they are horizontal to within ± 13002) Check the parallelism with a scale. Adjust the shafts so thatthey are parallel to within ± 1 A– B300= ( ).LFig. 15 Horizontal positioning of the shafts2) Generally, the slack of roller chain should be on the lowerside. Adequate slack is calculated by moving the chain byhand in a downward direction from the center. The chain slackthat you move by hand (SS’) should be about 4% of the span(A-B) (Ex. The amount of slack when span length is 31.5”would be 31.5” × 0.04 = 1 1/4”). See figure 14.Fig. 16 Parallelism of the shaftsA-111

Roller ChainInstallation & MaintenanceDrive Chain3) Correct the parallelism of the sprockets using a straight edge(or scale). Align the sprocket faces within the tolerancesshown below according to distance between sprockets.Up to 3.2 ft. + .04”3.2 ft. to 32 ft.:Over 32 ft.: + 0.4”Distance between shafts (ft.)122) When chain speed is fast and load fluctuates:The natural vibration frequency of roller chain and theshock cycle of pumping machinery, or chordal action (upand down movement) of roller chain may attune, causingthe roller chain to vibrate. In this case, a guide shoe(made of NBR or EPDM), etc. is used in order to stop theshaking and prevent vibration.3) When the center line is vertical:Install a tensioner that can automatically eliminate theextra chain slack. If the driving shaft is on the bottom, atensioner must be installed.Fig. 17 Alignment of sprockets4) Sprockets are fixed to shafts using Power Locks, LockSprockets, and keys (colors and bolt sets, etc. if required).4.5 Layouts ( used in the figures below denotes the driveside)1) General LayoutsWhen designing the roller chain drive, the centerline of bothsprockets should be close to horizontal. If installation is closeto vertical, it is desirable to install an idler or a guide shoebecause even slight elongation can cause the chain to comeoff the sprocket. The angle of inclination should be kept within60°.Fig. 21 Vibration preventive guide shoe4.6 Installation of Lambda Curved Chain1)Guide InstallationLambda Curved Chain has a greater degree of freedom withregard to the clearance between the pins and bushingscompared to standard chain. Therefore, a chain guide shouldbe installed to ensure that the chain directly engages with thesprocket.Fig. 18 General layouts2) Layouts Requiring Attention1) When the slack is on top:When the center distance is short, move the shafts toadjust the center distance of the sprockets until the chainfeels tight.Fig. 22 Vertical drives2) Minimum Radius (r)The R dimension of the guide should be greater than theminimum radii shown in the following table.Fig. 19 Layout when the center distance is shortIllustration of guideWhen the center distance is long, chain slack is adjustedby installing an idler, which supports the roller chain.RSC40CU-LambdaRSC50CU-LambdaRSC60CU-LambdaMinimum Radius (r)15.75”19.70”23.60”A-112Fig.20 Layout when center distance is long.

Roller ChainInstallation & Maintenance5. Chain Test RunAfter installing the chain, carry out a test run and check the following items before you actually start running the chain.5.1 Pre-Test Run1) Connecting link plates, clips, and cotter pins are installed correctly.2) Chain slack has been properly adjusted.3) Adequate lubrication is available.4) The chain isn’t touching any objects, such as chain cases, etc.5) There are no obstacles in the chain operating area, and all is clean.5.2 Test-Run1) Sound. There should be no strange noises. Make sure the chain doesn’t touch the case.2) Vibration. Look for excessive chain vibration.3) Sprocket-chain interaction. Make sure the chain doesn’t climb over the sprockets.4) Sprockets. Ensure that the chain separates smoothly from the sprocket.5) Chain articulation. The chain should articulate smoothly.Drive ChainIf you notice any of these conditions, do not begin operation. Correct any problems before proceeding any further.6. Roller Chain Inspection1) Roller chain needs to be replaced when parts are damaged or when there has been 1.5% wear elongation. Try to replacethe chain before this kind of situation occurs.2) If roller chain selection and operating conditions are suitable, you can expect long life and low chain maintenance.Eventually the pins and bushings will wear; and the chain will need to be replaced. Listed below is an inspection check list.6.1 Inspection ChecklistTable 3ProceduresStep IStep IIStep IIIMethodVisually check the chainduring operation and lookfor any abnormalities.Stop the chain andcarefully inspect each partof the chain and sprocket.In order to investigate inmore detail, remove theroller chain and inspect itvisually or check it withmeasuring instruments.Inspection Items1. Sound. There should be no strange noises.2. Vibration. Look for excessive chain vibration.3. Sprocket-chain interaction. Make sure the chain doesn’t climb over thesprockets.4. The chain isn’t jammed in 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 link plate side and edgesurfaces, pin edges, and roller surfaces.2. Inspect for pin rotation and the clearance between the link plate and thepins.3. Inspect the sprocket teeth surfaces and teeth side surfaces forscratches 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 a terminating device for lift applications, inspect the wear ofthe end bolts and the wear of the connecting link plate pins. Also checkfor proper installation at the same time.1. The inspection items are identical to those in Step II, however,everything is checked in more detail.Reference page fordetailsInspection pointsare on thefollowing pagesand on thetroubleshootingand problemsolvingpagesA-113

Roller ChainInstallation & MaintenanceDrive Chain6.2 Inspection IntervalsRegular inspection of roller chain is recommend at one-monthintervals. Inspection should be carried out at shorter intervals inthe following cases.1. Special or corrosive environments2. High speeds with sudden stoppage3. Lifting or indexing operations6.3 Inspection requirements for ordinary transmission1) Inspecting condition of lubrication1) While the chain is driving, check to see if there islubrication in the clearance between the outer link plateand inner link plate. Also check if the chain or rotating discis immersed in lubricating oil.2) When the chain is stationary, the chain surface willgenerally appear dirty from wear dust if lubrication isunsatisfactory. This is especially the case between the linkplates.3) When the chain is removed, connecting link pins and theedge of the inside of the bushings should be checked. Ifthere are any scratches, red or reddish-brown color,lubrication is improper or insufficient.2) Inspection of link plates1) If repeated loads over the maximum allowable load are puton the chain, there is a strong possibility of fatiguebreakage of the link plate. It is difficult to notice initialcracking from fatigue breakage simply from externalobservation.3) Inspection of pinsWhen the pins rotate, the roller chain must be completelyreplaced with new chain. This also applies to the connectingpins. By removing the connecting parts it is possible to see theconditions of wear and rust on the surfaces of the pins.Fig. 25 Rotation of the pins4) Inspection of the rollers1) As with the link plates, if rollers are also subjected to loadsover the maximum allowable load, the repeated impactload between the chain and the sprockets may causefatigue breakage to occur. The roller should be checked inthe same way as the link plate.2) If foreign objects interfere with the engagement of theroller and sprocket, the roller may be damaged and acrack may develop. Careful attention should be paid to theabove. In high-speed operations, even if foreign objectsdo not interfere with engagement, cracks may appear fromthe impact with the sprocket teeth.3) Chains damaged from fatigue breakage of the rollers mustbe completely replaced, because each part has receivedthe same amount of repeated load.2) Usually, a crack develops at the edge of a hole or at theside of the link plate, as shown in the illustrations below.The presence of cracks should be checked carefully.Fatigue breakage progresses little by little, so it can benoticed if close attention is paid.HFig. 23 Cracks on the link platesH × 5%Example of a crackFig. 24 Wear on the edges of the link plates3) When wear occurs from sliding between the edges of theplates and the guides, it is necessary to adjust the positionof either the chain or the guides. The allowable wear onthe link plates is limited to 5% of their height.Fig. 26 Cracks on the rollers4) Also check if the roller rotation is poor.5) Inspection of the sprockets1) Chain and sprocket engagement can be checked byobserving the roller and surface of the teeth. Properengagement is when the contact area is uniform with pointA in the illustration (figure 27). If the contact area islopsided or the sides of the teeth are wearing away (pointB in figure 27), this may have been caused from improperinstallation of the sprockets or twisting of the roller chain.In this case, rechecking/readjustment is necessary.2) The normal point of impact is slightly up from the toothbottom. However, when initial tension is applied to thechain and tension remains on the slack side, the roller willslightly touch the tooth bottom. However, point A (figure27) receives the strongest impact.A-114

Roller ChainInstallation & Maintenance3) When idlers or tensioners are used, the contact area willbe the center of the tooth bottom.ImproperinstallationImproper installation causesthe surface of the teeth tobecome ground down.Fig. 27 Contact area of the sprocket teeth4) Sprockets generally need to be replaced when tooth wear(shown in table 4) has been reached. Sprockets withinduction hardened teeth need to be replaced when thehardening layer is worn.6) Inspection of chain elongation1) Chain elongation is caused not by deformation of the linkplate, but by wear on the pin and bushing. Therefore, theremaining chain life can be estimated by periodicallymeasuring the chain elongation.2) Measuring chain elongation(1) The chain should be measured while stretching itslightly to eliminate any slack.(2) Measure the distance of the inside (L 1 ) and outside (L 2 )of the rollers at both ends of the measured links using acaliper, to get a measurement (L).L= L 1 + L 22(3) When measuring, use at least 6 to 10 links to help keepany measuring error down to a minimum.Drive ChainSprocket Replacement Guide(Based on Tooth Thickness/Dimension B)Table 4All dimensions in inches unless otherwise stated.Size of RS Dimension BRoller Chain Normal Pin-GearRS 11 0.024 —RS 15 0.043 —RS 25 0.059 —RS 35 0.098 —RS 41 0.102—RS 40 0.0980.106RS 50 0.1140.134RS 60 0.1460.169RS 80 0.1970.228RS100 0.2720.307RS120 0.3430.390RS140 0.4170.469RS160 0.4880.559RS180 0.4450.535RS200 0.4960.591RS240 0.5940.713RF320T 0.7830.957RF400T 0.980Size of BSRoller ChainDimension BNormalRS05B 0.063RF06BRS08BRS10BRS12BRS16BRS20BRS24BRS28BRS32BRS40B0.0630.0830.1140.1420.1970.2680.2830.3390.4690.500Note: Pin-Gear tooththicknesses are all 18T.5) If a new roller chain is run on a worn sprocket, the chainwill wear at a faster rate than normal. In this case, whenreplacing the chain, replacement of the sprocket is alsorecommended.Fig. 28 Measurement of length(4) Finding the chain elongationChain elongation (%) = Measured length – Standard length × 100Standard lengthStandard length = Chain pitch × Number of links(5) For multi-strand roller chain, the measurement is carriedout in the same way as for single strand roller chain ofthe same pitch.(6) The limit of usage based on roller chain elongation for asmooth transmission is as follows.Table 5Maximum allowable elongationLarge sprocket with up to 60 teeth Chain elongation 1.5%Large sprocket with between 61 - 80 teeth Chain elongation 1.2%Large sprocket with between 81 - 100 teeth Chain elongation 1.0%Large sprocket with between 101 - 110 teeth Chain elongation 0.8%A-115

Roller ChainInstallation & MaintenanceDrive Chain(7) Dimensions for evaluating standard length (chain pitch ×number of links) and 1.5% elongation are shown inTable 6 below.(8) When the length of the roller chain cannot be measuredwith a vernier, a tape measure may be used; however,measurements need to be taken over as many links aspossible to reduce measuring error.(9) Lifespan of Lambda and X-Lambda roller chain. Whenchain elongation of Lambda Roller Chain reaches about0.5% it may be losing its lubricating properties. This maybe determined by the adhesion of red wear particlesbetween the plates and the occurrence of articulationstiffness. When this occurs, the life of the chain hasbeen reached.4) Inspection of twisting and side bending of the roller chain.If partial twisting or side bending of the chain occurs, thecomplete roller chain should be replaced.

(Refer item 3.2 on page A-109)3) The parts where the roller chain bends around the sprocketshould be checked when inspecting the wear elongation ofthe roller chain.Fig. 29 Roller Chain Twisting5) End bracketsCheck for damage by deformation of the hole due to wear.If the hole is damaged or deformed, replace the end bracketimmediately. The clearance on the pinhole of the bracketaffects the life of the roller chain and should be kept to aminimum.Fig. 30 Wear on the end bracket hole6.5 StorageAvoid storing spare parts, such as a roller chain, sprockets, andend brackets in high temperature/high humidity and dustyenvironments. Also, when storing roller chain that has beenremoved, wash the roller chain and then apply lubrication. Afterthe roller chain clearances have been supplied with a sufficientamount of lubricant, wrap the chain in grease paper beforestoring away.A-116

Roller ChainInstallation & Maintenance7. Precautions for Use in Damp, Corrosive and AbrasiveEnvironmentsWhere possible, roller chain should be used in clean environments. When roller chain is used in damp, corrosive or abrasiveenvironments follow these precautions:7.1 Use in damp conditionsIf the chain is exposed to water or steam 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.A) Countermeasures(I) Reduce bearing pressure using a larger sized chain to improve wearresistance.(II) Use corrosion resistant roller chain for rust prevention.Drive Chain7.2 Use in corrosive conditionsIf roller chain is exposed to acids or alkaline conditions, such as battery acid andliquid used in plating processes, 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), electro-chemicalcorrosion may occur.6) There are also circumstances where even stainless steel roller chain will corrode.Fig. 31 shows an example of chain that was used in a plating apparatus. The chainfell to pieces within one month due to the affect of the acid.A) Countermeasures for embrittlement fractures (stress corrosion cracking):(I) Adopt a brittleness countermeasure that lowers crack susceptibility.(II) Install a cover or casing to prevent acids or alkalis from contacting the chain.(III) Adopt a high-grade material with anti-corrosive properties.B) Countermeasures for corrosion:(I) Use surface-treated chain.(II) Install a cover or casing to prevent acids or alkalis from contacting the chain.(III) Adopt a high-grade material with anti-corrosive properties.Fig. 31 Corrosion of stainless steelroller chainFig. 32 Hydrogen embrittlementcrackingIn general, embrittlement fractures (stress corrosion cracking) occur around the link plate holes. This is the area where the pin andbushing are press-fitted to the link plate. This area has the highest concentration of stress. Cracks are generated even when there isno tension on the chain. Roller chain in general is more susceptible to acids than alkalis, and in special cases, embrittlement fractures(stress corrosion cracking) are generated by seawater or pit water.7.3 Use in abrasive conditions where abrasion is a problemIf the chain is exposed to strong abrasive materials (eg. sand and metal particles), the following problems may occur:1) When the abrasive materials penetrate between the pins and bushings, chain wear is accelerated and poor articulation results.2) When the abrasive materials penetrate between the bushings and rollers, chain wear is accelerated and poor roller rotation results.3) When the abrasive materials penetrate between the link plates, poor articulation results.A) How to prevent abrasion.(I) Apply a dust-cover.(II) Remove foreign particles by regularly washing the roller chain.(III) Reduce bearing pressure by using a larger sized chain to improve wear resistance.(IV) Increase abrasion resistance by applying special processing to the parts of the chain where abrasion is a problem.A-117

Roller ChainInstallation & Maintenance8. Drive System (Roller Chain and Sprockets) Troubleshooting Guide8.1 GeneralProblemPossible CausesSolutionDrive ChainChain is riding up onthe sprocket.The roller chain and sprocket do notmatch.Excessive load.Elongation of the chain due to wear orexcessively worn sprocket teeth.Replace the chain or sprocket with the correct size.Decrease the load, or increase the number of strands or sizeof the chain.Replace with new chain and sprockets.Improper installation of the sprocket orshaft.Inspect and correct.Chain casing or bearings are loose.Tighten all bolts and nuts.Unusual noises.Excessive or insufficient slack in thechain.Adjust the distance between shafts to obtain the properamount of slack.Excessively worn chain or sprocket.Replace the chain and sprocket with new chain and sprocket.Lack of or unsuitable lubrication.Provide proper lubrication according to the operatingconditions.Excessive vibrations inchain.Chain is resonating with periodicexternal force.Change the chain’s mode of vibration.1. Preventing resonance.a. To change the natural frequency of the chain.• Alter the effective tension either by applying an initialtension or adjusting the existing one.• Install a tensioner to change the chain span.• Replace the chain. Choose a different quality and springcoefficient.b. Change the vibration frequency.• Change the speed of rotation of the sprocket.• Re-evaluate the device set-up.2. Mechanically reducing the vibrations.• Install a guideshoe.• Install a selfadjustingtensioner on theslack side.Load fluctuations are excessively large.Reduce fluctuations with fluid coupling or similar technique.Span between shafts is too large.Install an idler.The chain winds ontothe sprocket(Poor separation fromthe sprocket teeth)Excessive slack in chain.Elongation of the chain due to chainwear or excessively worn sprocket teeth.Adjust the chain length or distance between shafts. Install atensioner.Replace with new chain and sprocket.A-118

Roller ChainInstallation & MaintenanceProblemPossible CausesSolutionRusting of the chainImproper lubrication or poorenvironment.Replace chain and protect it from the environment with chaincasing or proper lubrication.Excessive wear on theinside surface of thelink plates and sides ofthe sprocket teeth.Excessive wear on thelink plate side surfacesand pin heads.Improper installation.Improper installationof guides, etc.Correct sprocket and shaft installation.Check the condition of the guides, and increase the gapbetween the guides and the chain.Drive ChainChain is not installed correctly.Inspect the installation and correct as necessary.Contamination from metal dust or dirtbecause of improper lubrication.Remove the chain, wash it thoroughly, and provide properlubrication.Excessive load or bent pin.Reduce the load or increase the number of or size of chains.Replace chain with a larger size.Corrosion or rusting.Install a chain casing to protect the chain.Improper flex orbending of chain, tightjoints.Seizing from improper lubrication.Provide proper lubrication according to the operatingconditions.Seizing of pin and bushing.Provide the proper operating conditions.Pin and bushing seized from high-speedoperation. This causes improperbending and can lead to chainbreakage.Uneven or excessive loading caused byimproper installation.Replace with new chain and correct installation.Spreading of linkplates.A-119

Roller ChainInstallation & Maintenance8.2 Link Plate RelatedProblemBreakage of link plate.Possible CausesExcessively large shock load.SolutionReduce shock loads by making the start-up, stopping, andother actions smoother (installing a shock absorber, etc.).Increase the size or number of chains.Drive ChainVibrations in the chain.Large inertia in the driven machine(excessive load).Install an anti-vibration device (for example, tensioner oridler). Refer to “Excessive vibration in chain” page (foundearlier in this section).Increase the size or number of chains.Corrosion.Replace with a new chain. Install a casing to protect thechain. Periodically clean the chain.(1) Static fracture.Stretching the link plate witha tensile load beyond itsbreaking load will cause it tostretch and then break.(2) Fatigue fracture.By repeatedly applying aload past its fatigue limit(fatigue strength), thefatigue will start at holesand then suddenly break.(3) Offset link plate fatigue.Offset link plates are bent atthe center, and the resultingconcentration of stress at thebend can cause a fatiguebreak. Avoid using offset linksin high-stress applications.Cracks in the linkplates (fatigue), whichare perpendicular tothe direction of pull.Loads are greater than the maximumallowable load. And this excessive loadis repeating.Remove all large loads. If it is not possible to remove theexcess load, then increase the size or number of chains.Replace with a new chain.Deformation of link plateholes.Excessive load.Remove excessive load. Replace with a new chain.Corrosion stress cracksappear, usually as bowshapedcracks in thelink plate.The chain is being used in corrosive(acidic or alkaline) conditions. (This isnot caused by a repetitive load).• Replace with a new chain. Install a casing to protect thechain from the corrosive conditions.• Or use an anti-corrosive chain. (See anti-corrosive rollerchain section in this catalogue).A-120

Roller ChainInstallation & Maintenance8.3 Pin RelatedProblemsBreakage of pin.Possible CausesExcessively large shock loads.Subject to a repetitive load greater thanthe fatigue limit of the pin.Corrosion.SolutionReduce shock loads by making the start-up, stopping, andother actions smoother.Remove the large repetitive load or increase the size ornumber of chains.Install a casing to protect the chain. Periodically clean andlubricate the chains.Drive Chain(1) Static fracture.The type of fracture found when subjectingthe chain to the breakage test. Occurswhen chain is subjected to a load greaterthan its breakage strength.(2) Fatigue fracture.Occurs when the pin isrepetitively subjected to loadsgreater than its fatigue limit. Recheckthe size of the peak loadand formulate a countermeasure.(3) Shock-induced bending fracture.The 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 when thesurface of the pin has corroded.Pin rotates or begins tostick out.Wear or rust occursonly at the connectingpin in a liftingapplication or similaroperation.Excessive load or improper lubrication.Operating a chain at high load withoutproper lubrication can create frictionbetween the pin and bushing, causingthe pin to rotate. In this condition, thepin may come out, leading to chainbreakage.Improper initial lubrication at installation.Replace with new chain. Improve the lubrication or loadingconditions.Replace with new chain immediately. Do not weld or reusethe pins. If the pin head or link plate surface is worn, checkthe installation.Replace the connecting link. If pin wear is excessive, alsoreplace the chain. Properly install the connecting section fordevices such as end brackets used for lifting applications,etc.A-121

When revisions of thesestandards are published, the updated edition shall apply.Drive Chain2. Always lock out the power switch before installing, removing, lubricating or servicing a chain system.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 directionfor pin/rivet removal or insertion.e. Do not attempt to rework damaged chains by replacing only the components obviously faulty. The entire chain may becompromised, and it should be discarded.4. Other cautions:a. Alterations and Repairs to chains should be made only by qualified personnel with parts and components authorizedby Tsubaki.b. Electroplating of Assembled Chains is not recommended. Plating of assembled chains could result in failure fromhydrogen embrittlement.c. Inspect Chains for shipment damage before installation. During operation, all chain systems should be inspected on aregular schedule. Visually check for worn, damaged and broken parts caused by improper installation or maintenance,abnormal stress, temperature, humidity, abrasion or corrosion, possible interference with other system components andimproper lubrication. (For correct lubrication procedures and systems, see the Installation and Maintenance section.)d. Heating Chain with a cutting torch is not suggested unless absolutely necessary for removal. If cut in such a manner,it should not be reused.e. Welding should not be performed on any chain or component.f. Average Tensile Strength of a chain means the average load at which it will break when subjected to a destructivetensile test. It does not mean working load.
