0Roller 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 event
of 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 thelube-free Lambda Chain series.)
� Overload may cause Roller Chain to break.(Overload breakage can be avoided through careful selection, considering inertiaor by using identically-sized SUPER Roller Chain.)
� Unfavorable environmental conditions such as corrosion may cause eventualRoller Chain breakage.(This can be avoided by making sure the chain doesn’t come in contact with cor-rosive liquids or steam, etc. Alternatively, the Anti-Corrosive series is recommend-ed.)
� Correctly install Roller Chain to avoid misalignment or uneven wear and possiblebreakage.

Power transmission machines use chains, gears, or belts. The table below provides acomparison of typical applications. In general, chain is an economical part of powertransmission machines for low speeds and large loads. However, it is also possible touse chain in high-speed conditions like automobile engine camshaft drives. This isaccomplished by devising a method of operation and lubrication.
General Comparison ofTransmission Elements
Features1. Accommodates large speed reductions/increases (Usually up to 1 : 7)2. Chain can accommodate long shaft center distances (normally less than 4 m), and
is more 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 receives
support in short distances between the shafts.6. Standardization of chains under the American National Standards Institute (ANSI),
the International 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 theloading over 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 polygo-
nal effect of the sprockets.(Shock can be reduced under the same speed ratio, by either reducing the chainpitch or increasing the number of sprocket teeth.)
2. During transmission, a particular method of lubrication is necessary according tospeed.
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.

Explanation of Terms 1. JIS Minimum Tensile Strength (Tensile Breakage Strength)This is the Minimum Tensile Strength determined by JIS. If a roller chain breaks by atensile load below this value, then it does not surpass JIS standards. In the case ofmulti-strand roller chain, the single strand value is multiplied by the number ofstrands. (JIS B 1801-1997)
2. Average Tensile StrengthThis is a fracture load reading obtained after a long period of actual tensile strengthtesting of a large number of chain strands. Of course, when any given strand of rollerchain fractures, this value may be higher or lower, so it does not represent a guaran-teed 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 stan-dards. This value differs depending on the manufacturer.
4. Tensile Strength Testing MethodAs shown in Fig. 2, roller chain with over five links is fixed at both ends by clevisesand is stretched until fracture occurs (JIS B 1801-1997). The type of fracture is indi-cated by breakage of the roller chain or failure of its parts (Fig. 3).

5. Maximum Allowable LoadThe Maximum Allowable Load of roller chain (excluding Stainless Steel Chain andEngineering Plastic Chain*) is the value derived from the lowest fatigue limit. When aload lower than this value is repetitively applied to the roller chain, fatigue failure willnever occur.
According to JIS B 1801-1997, the Maximum Allowable Load indicates a breakageload of Pmax = (Pm + Pa) = 2.2Pa at the frequency of 5 × 106, when a new rollerchain with over five links receives a repetitive load in linear operation (Fig. 4).
However, according to TSUBAKI’s standards, the catalog shows 2Pa at a frequencyof 107 as the Maximum Allowable Load.* Stainless Steel Chain and Engineering Plastic Chain
Surface pressure between the pins and bushings is specified from the wear performance,and Maximum Allowable Load is determined.
Note that the strength of one-pitch offset links is lower than the chain itself. (Refer toSlow Speed Selection Method : becomes 65% of the Maximum Allowable Load of themain chain.) However, the strength of two-pitch offset links is identical to that of themain chain.
6. Kilowatt Ratings TableRS Roller Chain and SUPER Roller Chain kW rating tables show kW values that allow15,000 hours of operation using a two-shaft drive and 100 pitches of roller chain un-der conditions 1 ~ 5 below. The kW ratings table of LAMBDA chain is based on conditions 1 ~ 4 and shows kWrating values when LAMBDA chain is used with two shafts. Lambda Chain has morethan 14 times the wear elongation of Standard RS Roller Chain operated without lubri-cation (#120 and #140 have five times). X-LAMBDA has more then five times the wearelongation 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 properly
installed (Refer item 4 on Pg. 96).4)There is minimal fluctuation in load during transmission.5)The recommended lubrication system and lubricant shown in the kW rating tables is
used for RS Roller Chain and SUPER Roller Chain (Refer Pgs. 94 & 95).
7. Moment of Inertia (I / J / GD2)Moment of Inertia is used to show the degree of inertia in rotational movement, in oth-er words, “rotation difficulty”, or “rotation ease.” This is equivalent to the mass (weight)of the object being used for straight-line transmission.Moment of Inertia is shown in the SI units table as: I = mk2 (kg·m2 m : mass of rotating body k : turning radius)It is shown in the Gravitational units table as:
(kgf·m·s2 G : mass of rotating body G : gravitational acceleration).
Although, GD2 = 4GJ (D : diameter of rotating body) is generally being used now inplace of Moment of Inertia.

Roller ChainStructure
1. Basic Structure
• PlateThe plate is the component that bears the tension placed on the chain. Usually this isa repeated loading, sometimes accompanied by shock. Therefore, the plate musthave not only great static tensile strength, but also must hold up to the dynamicforces of load and shock.
• PinThe pin is subject to shearing and bending forces transmitted by the plate. At thesame time, it forms a load-bearing part, together with the bushing, when the chainflexes during sprocket engagement. Therefore, the pin needs high tensile and shearstrength, resistance to bending, and also must have sufficient endurance againstshock and wear.
• BushingThe bushing is subject to complex forces from all parts, especially from the repetitionof shock loads when the chain engages the sprocket. Therefore, the bushing needsextremely high shock resistance. In addition, the bushing forms a load-bearing parttogether with the pin and as such requires great wear resistance.
• RollerThe roller is subject to impact load as it strikes the sprocket teeth during the chain en-gagement with the sprocket. After engagement, the roller changes its point of contactand balance. It is held between the sprocket teeth and bushing, and moves on thetooth face while receiving a compression load. Therefore, it must be resistant to wearand still have strength against shock, fatigue and compression. RS11 / 15 / 25 / 35 donot have rollers.
• Roller LinkTwo bushings are press fit into two roller link plates and rollers are inserted to allowrotation around the outside of the bushing. This is the same for single strand and mul-ti-strand chain.
• Pin Link and Inner Plate The pin link consists of two pins that have been press fit into two pin link plates. In thecase of multi-strand roller chain, an inner plate is added to the pin link. The inner plateis slip fit for Standard RS Roller Chain and press fit for SUPER Roller Chain.
Three Basic DimensionsPitch, Roller Diameter and Widthbetween Roller Link Plates areknown as the “Three BasicDimensions of Roller Chain.”When these three dimensions areidentical, roller chain and sprock-ets are dimensionally compatible. * Slip FitWhen the shafts and holes are fit-ted together, there is a continuousloose fit. This is a fit where therange of tolerance for the hole islarger than the range of tolerancefor the shaft (pin or bushing).* Press FitWhen the shafts and holes are fit-ted together, there is a continuousinterferential fit. This is a fit wherethe range of tolerance for the holeis smaller than the range of toler-ance for the shaft (pin or bush-ing).
Spring clips, cotter pins andspring pins are the parts thatprevent the connecting linkplate from falling off the pinand are extremely importantparts for maintaining the origi-nal strength of the chain. Don’tforget to install these neces-sary parts under any circum-stances.

2. 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 the need for connecting links will eventually arise. Although offset links can be used when there are an odd number oflinks in the roller chain, please use a design that requires an even number of links as much as possible.
2.1 Connecting Links
2.2 Offset Links
Note: 1. The connecting link plate fastening method for each chain size is indicated in the dimension tables and the table notes. 2. The color of F-type connecting links for RS Roller Chain and RS-HT Roller Chain marked with * is black.
1 Pitch Offset LinksWhen an OL is used, pleaseallow for a 20% reduction inkW ratings compared to thatof the main chain and a 35%reduction in MaximumAllowable Load kN (kgf).
2 Pitch Offset linksThe pin and offset link plateof a 2POL is press fit and isfastened by a rivet. They canbe used in accordance withthe kW ratings tables.Please refer to the dimension tables for roller chain types and sizes suitable for offset links.
Points to Note
• For multi-strand chain, make sure the plate with RC processingis on the outer most side when assembling.
• Operating speed is indicated by the white area in the kW ratingstable.
• Make sure to use the chain according to the specified applica-tions on page 73 and within the speed region of the coloredarea in the kW rating tables.
• Can be used in all areas of the kW ratings table for LambdaChain.
• RC processing is carried out on the connecting link plates.
• Please use the exclusive connecting links foreach chain type.
• Please use the exclusive connecting link for RS-HT Roller Chain.
• There are no connecting links, so use connectingpins for assembly.
• Refer to the dimension tables of each chain. Thechains that have RC processing on the connect-ing link plates are limited to NP Roller Chain, DPRoller Chain, WP Roller Chain, SN Roller Chainand BS Roller Chain.

What is Roller Chain Length Tolerance?
The method of testing for chain length and the allowable length tolerance is specified in JISB 1801-1997. The length tolerance of chain subjected to a measuring load specified by JISfor each chain size (Ex. RS80: 500 N (50.99 kgf)) is the standard chain length ±0 ~ 0.15%.Standard length refers to the standard chain pitch (P) × No. of links. (Applies to items shownwith a JIS number.)
How much elastic elongation is there depending on the chain load?
The diagram below shows the elastic elongation of chain subjected to load. The valuesshown are standard reference values and have been calculated using a single strand of RSRoller Chain. In actual fact there will be a slight variation. Furthermore, make sure not to sub-ject the roller chain to loads greater than the Maximum Allowable Load.

� Long life without lubricationThe most important determining factor of a chain’s life is lubrication. Even though the chain is non-lubricated, long life ispossible through the effectiveness of the special oil-impregnated bushing. And with the renewal of Lambda chain in1999 the wear life of New Generation Lambda far surpasses that of previous Lambda chain (Standard type).
• Twice the wear elongation life of previous Standard Lambda (–10°C ~ +60°C / +14°F ~ +140°F)• More than 14 times the wear elongation life of Standard RS Roller Chain
(N.B. #120 and #140 have 5 times the life of Standard RS Roller Chain)
� InterchangeabilityLambda Chain is interchangeable with Standard RS Roller Chain. However, as the pins are longer than that of StandardRS Roller Chain, please make sure that there is no interference with the machine.
� Operating Temperature–10°C ~ +150°C (+14°F ~ +302°F)
� SprocketStandard RS Roller Chain sprockets can be used. (Limited to single strand Roller Chain only)

LAMBDA CHAINNearly 15 years have now passed since Lambda Chain was introduced to the market thanks tothe continued support from all of our devoted customers. During this time, it has been used in avariety of industries and applications, and its wear resistant function has been highly regarded. With the renewal of Lambda Chain in 1999, we were able to achieve an even more highly func-tional and high quality chain than the conventional Lambda Chain (Standard type). We hope youcan make use of this chain, which reduces maintenance frequency, improves the working environ-ment and increases productivity.

� Operating Temperature: –10°C ~ +150°C (+14°F ~ +302°F)� Sprocket
Since the chain’s transverse pitch (C) differs to that of Standard RS Roller Chain, RS Standard Double-Strand Sprocketscannot be used. Exclusive sprockets must be used.
� kW Rating Capacity: (Multi-Strand Coefficient)The multi-strand coefficient of double-strand Lambda Chain is 1.4. Multiply the kilowatt rating values on pages 41 - 43when making your selection. In case of chain replacement there is a decline in kW rating capacity compared withStandard RS Roller Chain. Please confirm. In order to make the multi-strand coefficient the same as Standard RSDouble-Strand Roller Chain (1.7), it is necessary to increase the thickness of outer and middle link plates by one size.
� Offset LinkOffset links are not available. Please use an even number of links.
� Pin LengthThe plate thickness of the inner plate is thicker than that of Standard RS Roller Chain, and the pin length (L1, L2) hasbeen increased by the difference. Please check for any interference.

N� Are you satisfied with your current chain?When……
• Wear elongation occurs in a short period of time, and you are contin-ually replacing your chain;
• Wear elongation causes you to continually perform maintenance (Ex.machine positioning adjustments);
• You are already using a lube-free chain, but want to extend the peri-od of time between replacement;
……consider X-LAMBDA
� FeaturesUltra Long LifeThe inclusion of a felt seal in the construction of X-Λ has increased the anti-wear performance to more than 5 times that of Tsubaki’s LAMBDA chain. (In-house comparison at –10°C ~ +60°C (+14°F ~ +140°F))
Ambient temperature range (–10°C ~ +60°C/+14°F ~ +140°F)
Mid-Temperature Range (+150°C/+302°F)
� Operating Temperature–10°C ~ +150°C (+14°F ~ +302°F)
� SprocketStandard RS Roller Chain sprockets can be used. (Only for Single Strand Chain)

Lube-Free Roller Chain ®
The Definitive Lube-Free Roller Chain
X-LAMBDA Chain (Pat.)
Through the effectiveness of an oil impregnated “Felt Seal”, X-Λ Lambda Chain vastly outperforms the anti-wear functions of all previous Lambda specifications.

X-Lambda has no offset links.
For #80 size and above, the connecting links arecottered pin type.
� kW Rating Capacity: Pgs. 41 - 43� Operating Temperature: –10°C ~ +150°C (+14°F ~ +302°F)� Sprocket: Standard RS Roller Chain sprockets can be used. (Only for Single Strand Chain)� Attention for Use:
• Inner plate is thicker than Standard RS Roller Chain. Also, due to the insertion of the Felt Seal, the pin is now longer (L1,L2). Please check for any interference.
• Offset links are not available. Please use an even number of links.• As the Felt Seal is oil impregnated, the surface of X-Lambda has more oil on it than Standard Lambda Chain.
� Method of ConnectingWhen connecting the chain, please use an X-Lambda Chain connecting link (with a Felt Seal). As shown in Diag. 1, in-sert felt seals between the outer plate and the connecting link plate then attach the link. (Please refer to page 71 for es-sentials on cutting/connecting).

� NP Nickel-Plated Roller Chain *1
RS Roller Chain that has been plated with Nickel. NP chain has an attractive appear-ance and light corrosion resistance, so it is suitable for outdoor conditions exposed towater. There is a 15% reduction in Max. Allowable Load compared to RS Roller Chain,so please take care when making your chain selection. Working temperature range: –10°C ~ +60°C (+14°F ~ +140°F).
� WP Roller Chain *1
RS Roller Chain that has undergone a special surface treatment. (Clips are SUS301)This chain is more corrosion-resistant in wet environments than NP chain, and is alsosuitable for use in environments exposed to sea-water. The kilowatt ratings are thesame as RS Roller chain, however, it cannot be used in temperatures below –30°C(–22°F) and above +150°C (+302°F).
� DP Roller Chain (Patent Pending) *1
RS Roller Chain that has been galvanized and specially treated providing a doubleplated effect. It has superior salt-water resistance, weather resistance and other syn-thetic corrosion resistance and is extremely durable. Furthermore, this chain usesgroundbreaking surface treatment technology and the non-use of harmful chromiummakes this chain environmentally friendly. Working temperature range: –10°C ~ +60°C (+14°F ~ +140°F).
� SUS Stainless Steel Roller Chain Roller Chain composed of SUS304 (Clips are SUS301). This chain is more corrosion-resistant than RS Roller Chain, NP Roller Chain, and WP Roller Chain. It can be usedin special environments such as corrosive conditions underwater and in acids/alkalis.It can also be used in high and low temperatures (–20°C ~ +400°C/–4°F ~ +752°F).Please refer to the chain selection pages for more details on corrosion resistance.There is almost no magnetism regarding SUS304 stainless steel itself. However, theremay be slight magnetism under cold working processes.
� LS Stainless Steel Roller Chain PAT#2783750LS Chain is a roller chain in which an engineered plastic sleeve (black) has been in-serted between the pin and bushing of Stainless Steel Roller Chain (SS) (SUS304).There are two types of roller materials, SUS304 and engineering plastic (white).Corrosion resistance is almost identical to that of Stainless Steel Roller Chain (SS),however, care needs to be taken with some inorganic acids and alkalis. Please referto the chain selection pages for more details on corrosion resistance.
Working temperature range: –20°C ~ +100°C (–4°F ~ +212°F) (SUS304 rollers)–20°C ~ +80°C (–4°F ~ +176°F) (plastic rollers)
Long Life
Life comparison with SS specification
Completely Dry (No Lube)……chain wear life improved by more than 4 times
(–20°C ~ +100°C/–4°F ~ +212°F)
Realization of quiet drive and conveyance due to absence of metal on metal contact
• 7 ~ 10 dB reduction in noise compared to stainless steel rollers
• Reduction in screeching noise from direct metal contact
Reduction in mass compared to stainless steel rollers (Approx. 15%)
� Engineering Plastic Roller

� NS Stainless Steel Roller ChainThis is a roller chain composed of SUS316 stainless steel (only RS25NS clips areSUS301). This chain is suitable when corrosion resistance greater than Stainless SteelRoller Chain (SS) is required. There are no magnetic parts besides the clip. Please re-fer to the chain selection pages for more details on corrosion resistance.
� AS Powerful Stainless Steel Roller ChainThis is a roller chain which uses heat-treated precipitation hardened stainless steel(SUS600) for the pins and rollers and SUS304 stainless steel for the link plates andbushings (Clips are SUS301). Max. Allowable Load is 1.5 times that of Stainless SteelChain (SS) and corrosion resistance is slightly lower. This chain is suitable where cor-rosion and heat resistance (–20°C ~ +400°C/–4°F ~ +752°F) is required, and for pow-erful drives where chain smaller than RS Stainless Steel Roller Chain (SS) is preferred.Please refer to the chain selection pages for more details on corrosion resistance.Magnetism exists due to the use of SUS600.
� PC, PC-SY Poly Steel Chain®
PC:SUS304 is used for the pins and outer link plates (Clips are SUS301), and engi-neering plastic (white) is used for the inner link. It is a lube-free, low noise (5 dBlower than RS Roller Chain), and lightweight (50% lighter than RS Roller Chain)chain. Working temperature range: –20°C ~ +80°C (–4°F ~ +176°F). Please referto the chain selection pages for more details on corrosion resistance.
PC-SY (Super Chemical-Resistant): This chain uses titanium for the pins and outer linkplates and engineering plastic (off-white) for the inner link. It is suitable when thecorrosion resistance of Poly Steel Chain (PC) is lacking. Working temperaturerange: –20°C ~ +80°C (–4°F ~ +176°F). Please refer to the chain selection pagesfor more details on corrosion resistance.In addition, Max. Allowable Load is 60% that of Poly Steel Chain (PC).
� TI Roller ChainThis chain is composed of titanium, making it non-magnetic and highly corrosion re-sistant. Please refer to the chain selection pages for more details on corrosion resis-tance.
� KT Roller Chain (Cold-Resistant)This chain can be used in colder temperatures than RS Roller Chain. Working temper-ature range: –40°C ~ +60°C (–40°F ~ +14°F). This chain is suitable when the samekilowatt ratings as RS Roller Chain are required.

� Low Noise Benefits• Reduction of noise generated by the machines and equipment in the workplace
helps improve the overall work environment.• The low noise function is added to the machinery and equipment used for man-
ufacturing, and contributes to upgrading and improving the overall image.• Belts were considered as a countermeasure for noise, however, there are many
limitations in terms of application, strength and overall cost. Taking these fac-tors into consideration, Low Noise Chain is the perfect countermeasure.
• Recommended for applications where silence is a major concern, such asstage lifts used in theaters.
� FeaturesLow NoiseCompared with Tsubaki’s standard RS Roller Chain (pre-lubricated), noise levelsof SN Roller Chain are 6-8 dB lower.
InterchangeabilityDimensionally interchangeable with Standard Roller Chain.* Note: As there are limits to the drive power of SN Roller Chain, please check the drive power charts on Pgs. 64 - 66.
SelectionPlease select by referring to the kW ratings chart on the following page orbased on the Slow Speed Selection method (when chain speed is lessthan 50 m/min (164 ft/min)). Please refer to the selection pages for moredetails.
Operating Temperature: –10°C ~ +60°C (+14°F ~ +140°F)
Allowable Chain Speed: 200 m/min (656 ft/min)
Sprockets: RS Standard Sprockets can be used
Low Noise Roller Chain SN
SN Roller ChainTsubaki’s uniquely structured spring rollers are used for the chain rollers. When Tsubaki’s SNRoller Chain engages with the sprocket, the spring roller deforms and absorbs the force of the im-pact. The lower impact force reduces impact noise between chain and sprocket resulting in lowernoise levels. Compared with Tsubaki’s standard RS Roller Chain (pre-lubricated), noise levels ofSN Roller Chain are 6 ~ 8 dB lower. (In-house comparison testing)

2. SERVICE FACTORSTsubaki offers simplex, duplex and triplex chains in RF06Bto RS40B of BS/DIN European standard. In ANSI Americanstandard, up to 6 strands are available as standard itemsfrom RS40 to RS240 and up to triplex for RS25 and RS35. Inmultiple strand chain drives, the load is unequal across thewidth of the chain, so the transmission capability of multiplestrand chain is calculated using multiple strand factorsshown in the table below.
Service factor Ks
The chain’s transmission capacity is affected if there is fre-quent load fluctuation. The appropriate service factor Ks
must be applied based on the source of power and type ofmachine as shown in the table below.Please note that the service factor is never smaller than 1.0.
Speed factor Kv and sprocket teeth factor KC
Table 3 : Speed factor, Kv and sprocket teeth factor KC
Shock factor KThis coefficient is determined by the rate of inertia betweenthe prime mover and the driven machinery (rate of I, GD2)as well as the amount of backlash in the transmissionequipment. When rate of inertia R > 10, R = 10When rate of inertia R < 0.2, R = 0.2
When I or GD2 for either the prime mover or driven machin-ery is unknown, use the value of R on table 4.
Table 4 : Shock factor K
Imbalance load factor Ku
When carrying out shuttle traction and lifting with twochains, or four chains for shuttle drive and lifting, the chaintension is not uniform. This must be accounted for by multi-plying the following imbalance load coefficient Ku to adjustthe left-and-right load imbalance.Example : For four lifting strands, the imbalance load factorfor one strand Ku = 0.6 × 0.6 = 0.36

Table 6: Provisional selection chart for RS Roller Chain (Lambda Roller Chain)
How to use this table (Table 6)1. Example: Single strand chain, de-
sign kW = 5 kW
(1) Assume that the speed of thesmall sprocket is 100 r/min.Judging from the intersectingpoint of design kW value of 5 kW(vertical axis) and the speed val-ue of 100 r/min (horizontal axis),RS80 and a sprocket with be-tween 13 and 18 teeth would beappropriate. Therefore, based onthe position of the intersection,we can see that a 14T sprocketcan be 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 tableis used for tentative selectionsonly. The kW ratings tablesshould be used to confirm thechain sizes.
(3) When the chain speed is lessthan 50 m/min., it is more eco-nomical to select your RS RollerChain by slow speed selection.
(4) Please allow for a 20% drop inthe kW rating values shown in thedesign kW ratings chart (Table 6)when 1-pitch offset links areused.
(5) A 4-pitch offset link is availablefor SUPER Roller Chain and thekW ratings are the same as inTable 7.

Procedure 4-5(1) Select the chain and the number of teeth for the small
sprocket:
The number of teeth for the small sprocket and a chainthat satisfies the number of revolutions of the highspeed shaft and design kW can be found by using theprovisional selection tables (Tables 6 & 7) or the kW rat-ing tables. When doing so, choose a chain of minimumpitch having the necessary kW rating. When there is a shortage of performance with a singlestrand, choose multi-strand chain. Further, when theoutside diameter of the sprocket has been made assmall as possible and the distance between shafts re-duced due to the space limitation, use a multi-strandroller chain with a small pitch.
(2) Select the number of teeth for the large sprocket:
If the number of teeth for the small sprocket has beendetermined, then multiply this value by the speed ratioand determine the number of teeth for the large sprock-et.It is appropriate to have more than 15 teeth for the smallsprocket. However, if the number of teeth for the largesprocket exceeds 120 as a result, then this is not favor-able. When this happens, reduce the number of teethfor the small sprocket; although, it is recommended touse more than 13 teeth.
Procedure 7 If possible, try to avoid using an offset link when using anodd number of links. Instead, try adjusting the distance be-tween the shafts until an even number of links is attained.

Procedure 2: Use Table 2 to determine the service factorService factor Ks = 1.0
Procedure 3: Obtain design kW37 kW × 1.0 = 37 kW
Procedure 4, 5: Determine the chain and the number ofteeth for the sprocket. Based on the fact that the number of revolutions of the highspeed shaft is 750 r/min and the design kW is 37 kW, wecan find the chain number and the number of teeth of thesmall sprocket.
1. According to the kilowatt rating table, the best choicewould normally be a single strand of RS80-17 teeth.Since the speed ratio is 1/3 (250/750 r/min.), the neces-sary number of sprocket teeth would be 17 for the smallsprocket and 51 for the large sprocket. However, as theoutside diameters are 151 mm for 17 teeth and 427 mmfor 51 teeth, it exceeds the space limitation of 500 mm.(151 + 427 > 500 mm) Therefore, these sprockets are notsuitable.
2. As a single strand chain is not suitable, a double-strandRS60-2, 22 and 66 teeth would be possible.But this combination is not suitable due to the space limi-tation again (144 + 411 > 500 mm).
3. For triple strand, RS60-3, 15 and 45 teeth would be pos-sible.The sprocket’s diameters are 99 mm and 284 mm re-spectively, the sum of which is less than 500 mm. Thekilowatt rating of a 15 tooth sprocket for the RS60-3should be confirmed by the kilowatt rating for the RS60.The kilowatt rating of a 15 tooth sprocket is 14.1 kW at700 r/min, and 15.9 kW at 800 r/min. The kilowatt rating at750 r/min is about 15 kW. Since 15 kW is for a singlestrand chain, the kilowatt rating must be multiplied by amulti-strand factor of 2.5 for a triple strand (refer to Table1).Therefore, the kilowatt rating of RS60-3, 15 teeth at 750r/min. is 37.5 kW (15 × 2.5 = 37.5)
4. This 37.5 kW rating satisfies the design kW rating.
Procedure 6: Confirm the shaft diameterThe shaft diameter is confirmed by the dimension table.The max. shaft diameter of RS60-15T is 45.5 mm and canbe used for the shaft diameter of 45 mm. The maximumshaft diameter for RS60-3-45T is 63 mm and so satisfies ourshaft diameter of 60 mm. The outside diameter for bothsprockets is 90 mm and 284 mm respectively and fits withinthe prescribed space.
Procedure 7: Determine the distance between shaftsIf the center distance between shafts is 220 mm, 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.
Procedure 8: Confirm the method of lubrication From the kW 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.
Procedure 1: Data required

6. SLOW SPEED SELECTION (Starting frequency-less than 5 times/day (8hrs))
Method of selection that applies for ordinary transmis-sion where the chain speed V is less than 50 m/min
(1) Applicable when making a more economical selectionfor RS and SUPER chain.
(2) Applicable when selecting RS-HT, SUPER-H and UL-TRA SUPER chain.
(3) In the case of severe conditions, such as transmissionswith lange impact, particularly from large loads and sideforces, please use F-CLs and 2-pitch offset links.
(4) When using offset and standard connecting links, allowfor the following strengths as a percentage of the max.allowable tension.M-type CL : 100%F-type CL : 100%2-pitch offset link (2POL) : 100%(Ref)1-pitch offset link (OL) : 65%
(5) The slow speed selection is an economical method ofselection that uses the complete kW rating of the rollerchain and should only be selected upon properly ascer-taining the conditions of transmission. In particular it isvital that sufficient attention be given to shock loads.
(6) Chain tension becomes large when using SUPER, RS-HT, SUPER-H and ULTRA SUPER chain, so avoid usingcommercialy available sprockets made of cast ironsince the strength of the rim and boss portions will incertain cases be insufficient. RS standard sprockets A type and B type as well as Ctype provide sufficient strength. (Materials such asSS400, S35C, SC450, etc. have to be used)
(7) For the high speed side, use a sprocket with a harden-ing process carried out on the surface of its teeth.
(8) Since the bearing pressure will be extremely large, becertain to lubricate the chain.

0Roller Chain Selection for Lifting Applications(1) When making your selection, calculate the tension from the load and from the motor and apply the greater of the
two. As a rule of thumb, if the greater value is lower than the Max. Allowable Load of the chain you are thinking ofchoosing, then it may be selected.
(2) If there are any laws or guidelines for chain selection, check and calculate accordingly. Make sure to follow themanufacturer’s selections and select the safer of the two selections.
(3) The chain speed should be less than 50m/min.(4) Use F-Type (Semi Press-fit) connecting links. Offset links cannot be used.(5) Lubricate the chain joints as much as possible after you reduce the loads. Sufficient lubrication is also required at
end fittings (end bolts and connecting links, etc.) and connecting parts, etc.

(Conclusion)
It is possible to use SUPER 120 for lifting applications and SUPER 100 for drive applications. However, if operational restrictions occur
due to overload, the chains will be subjected to the following loads: Drive chain: Fd = 0.073 × 1000 × 60 × 2 = 61.4 kN (6266 kgf) (per
strand), Fd × Ku = 61.4 kN × 0.6 = 36.8 kN (3757 kgf), Lifting chain: Fd × 303.75 = 65.3 kN (6657 kgf).
In this case, since there is a possibility of chain plastic deformation, increase the chain size by selecting SUPER 120-2 for lifting
transmission and SUPER 120 for drive transmission, just to be safe.

Accordingly, tooth-jumping will not occur if a 39 kg weight is used. However,
this will change depending on the layout and amount of wear on the Roller
Chain and sprocket teeth. Please use the above as a reference.
When comparing the calculated design chain tensions in Steps q, w, and e, note that Fb in Step e is the greatest.

9. Selection by Temperature
9.1 RS Roller Chain Selection by Temperature
Method of selection that allows for a decrease in strength depending on temperature. Additionally, lubrication should becarried out using a suitable lubricant according to the operating temperature.1) Problems of roller chain transmission at high temperatures
1) Increase in wear from a decrease in hardness2) Increase in elongation from softening3) Poor articulation and an increase in wear from depletion/carbonization of oil4) Increase in wear and poor articulation from scaling
2) Problems of roller chain transmission at low temperatures1) Decrease in shock resistance from brittleness at low temperatures2) Solidification of lubricant3) Poor articulation from frost and water adhesion

9.2 Method of selection of SS / NS Stainless Steel Roller Chain for high temperatures (+400°C / +752°F and above)Chain strength falls as the temperature of the chain becomes high. The temperature limit for use is decided by the tempera-ture of the chain itself. If your operation runs at temperatures higher than +400°C (+752°F), consult the manufacturer beforemaking your chain selection. Note that the chain cannot be used in temperatures in excess of +700°C (+1,292°F). Thechain speed should be less than 50 m/min for selections 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 bechanged.
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 50 m/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 formula

USE CARE TO PREVENT INJURY
• Do not carry out any rework on the chain under any circumstances.· Do not anneal any parts of the roller chain.· Do not wash roller chain with acidic or alkaline solutions. This may result in cracking.· Avoid electroplating of the roller chain and its parts since it may lead to cracking caused by hydrogen em-
brittlement.· Avoid welding on the chain. This will decrease the strength of the chain and cause cracking.· If parts are heated or cut by a torch, the links beside the affected part should be removed and discarded.
• Avoid replacing only parts that are partially worn or damaged with new parts. The whole chain should be re-placed in such cases.
• Install barriers and clear the area of all personnel below the items being lifted when using roller chain in liftingapplications.
• Install safety devices (safety covers, etc.) on all roller chain and sprockets.
• When connecting, disconnecting, maintaining & inspecting and lubricating,· Carry out all steps according to our catalog or manual. · Always lock out the power switch and prevent accidental activation of power in advance.· Connect the chain firmly to prevent unexpected movement of chain and parts.· Correctly use pressing equipment and other exclusive tools for disconnecting / connecting.· Make sure to wear suitable work clothes and protective equipment (safety glasses, gloves and safety
shoes).· Ensure that only skilled people carry out chain replacement.
Comply with the following to avoid serious personal injury.
0 WARNING
• Only handle chain after understanding its construction and specifications.
• Please inspect in advance whether any damage was caused during transportation when installing the chain.
• Make sure to carry out periodical maintenance and inspection of the chain and sprockets.
• Chain strength differs depending on the manufacturer. Ensure that TSUBAKI products are used when selec-tion is carried out based on TSUBAKI’s catalog.
• The minimum tensile strength is the minimum load that will cause the chain to fail when such a load is appliedonce to the chain. This is not an allowable load.
Comply with the following to prevent accidents.

1.2 Using a chain breaker1)For riveted type roller chain, grind down one end of the
outer link plate’s two pins(same side) to the surfaceof the link plate. (Same as1.1) Remove the cotterpin for cotter pin typeroller 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.Then make sure not touse this part if it has comeloose or deformed.
1.3 How to cut Poly Steel Chain1)Support the outer link plate of the chain in the cradle and
push down on the pinhead with the exclusive punch.Then lightly hit the head of the punch using a hammer.
2)Avoid using excess force on the engineering plastic part,as there is a possibility of causing damage.
1. How to Cut Roller ChainIf the chain you purchased is either a unit length (3,048mm) or on a reel, it is necessary for you to cut the chain tothe necessary length.
How to cut Roller Chain
1.1 Using a chain vice and punch1)For riveted type roller chain, grind down one end of the
outer link plate’s two pins (same side) to the surface ofthe link plate. Be careful of the chain overheating duringthe grinding process. In the case of Lambda Chain,grinding should be carried out slowly so as not to over-heat the bushings in particular. This process is unneces-sary for Poly Steel Chain as there are no rivets.
2)Remove the cotter pin for cotter pin type roller chain.
3)As shown in the photo, put the roller chain into the grooveof the chain vice (refer to Peripheral Tools section) andtighten the vice to secure the roller to be disassembled.(1) Please follow 1.3 and 1.4 for Poly Steel Chain and
Lambda Chain.(2) For multi-strand SUPER Roller Chain, put the far end
roller into the groove of the chain vice.
4)Place the appropriate pri-mary punch (refer toPeripheral Tools section),according to chain size,on the head of the groundpin, and then hit the headof the primary punch witha hammer. Make sure tohit the pins alternatively toensure the pins are re-moved evenly and at thesame time. Continue totap the pin until just be-fore the pin is removedfrom the outer link plate.
5)Use the secondary punch (refer Pg. 71) to remove thepin completely from the outer link plate. Check to makesure that the bushing where the pin was removed has notcome loose or deformed. Then make sure not to use thispart if it has come loose or deformed.

made 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.
93
1.4 How to cut Lambda Chain1)Support the chain with a chain vice or something similar,
and grind down one end of the outer link plate’s two pins(same side) to the surface of the link plate. Be careful ofthe chain overheating during the grinding process.Grinding should be carried out slowly so as not to over-heat the bushings in particular.
2)The chain is then cut using an exclusive cradle (refer toPeripheral Tools section) and an RS Roller Chain punch.Important points for cutting are outlined in 4) and 5) in1.1. However, please use an exclusive cradle instead ofa vice.
3)Hit the pins alternatively when removing the pins with apunch. Take extra care not to remove or cause any dam-age to the bushing. Make sure not to use this part if thebushing has come loose or been damaged.
2. How to Connect Roller Chain
2.1 When connecting chain on sprocket teethWhen connecting or disconnecting roller chain, it is conve-nient to use the sprocket teeth. Please carry out the follow-ing steps.1)Wind the chain around one of the sprockets such that
both ends of the chain are facing each other on thesprocket.
2)Apply oil and grease to the connecting link.3) Insert the connecting link in the two end links of the
chain.4) Insert the connecting link plate of the connecting link and
fasten the plate using the clips/cotter pins or spring pinssupplied.
5)When using a press-fit connecting link or F-Type (SemiPress-fit) connecting link, insert the connecting link plateby tapping it with a hammer until it moves into position.Then fasten it usingthe clips/cotter pinsor spring pins sup-plied.
6)When using thesprocket teeth to con-nect the chain, takecare not to damagethe teeth, particularlywhen using a castiron sprocket.
2.2 When connecting between shaftsIf the sprocket cannot be used due to the layout, pleasecarry out the following steps.1)Wind the chain around the sprockets and pull the chain
ends together using a chain puller (refer to PeripheralTools section) or wire.
2)Apply oil and greaseto the connecting link.
3) Insert the connectinglink in the two endlinks of the chain.
4) Insert the connecting link plate of the connecting link andfasten the plate using the clips/cotter pins or spring pinssupplied.
2.3 Clips and Cotter Pins1)Clips
Clips are used for small size roller chain (under RS60)connecting links. When connecting the chain, the clipshould be inserted securely into the slot of the pin on theconnecting link after the connecting plate has been in-serted on the pin. If the legs of the clips are spread toofar they will not catch properly and will fall of during oper-ation of the chain causing acci-dents. Care should be takenwhen inserting them. The direc-tion in which the clip is installedis generally opposite to the di-rection of travel for the chain asshown in Fig.10.
2)Cotter PinsTSUBAKI’s cotter pins are heat treated. The legs of thecotter pins should be bent to an angle of approx. 60 de-grees. Cotter pins should not be reused, and commer-cially available cotter pins other than those produced byTSUBAKI should be avoided.

0Safety Precautions(1) Avoid using offset links wherever possible by varying the
center distance between shafts or using an idler. (2) In the case of pins and connecting link plate holes being
press-fit type with F-type or other connecting links, pleaseavoid widening the connecting link plate hole or narrowingthe pin diameter to make connecting easier, as this willresult in a reduction in roller chain strength causing anaccident.
(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, as the detachment results in a reduction instrength.

3. RS Roller Chain LubricationOne of the most important factors in getting the best possible performance from your roller chain is proper lubrication.Particularly when performance requirements become more severe, the need for lubrication becomes more and more impor-tant. No matter how well a transmission system is designed, if it is not properly lubricated its service life will be reduced. Sinceservice life may be completely used up in such a short period of time, depending on the operating conditions, please payparticular attention to lubrication.1)The main purpose of lubricating and greasing is to limit wear elongation and prevent corrosion of the chain. Wear elonga-
tion arises from wear between the pin and bushing when the chain articulates. 2)TSUBAKI roller chain is pre-lubricated before packing. Since high-grade oil with a rust protection and lubricating effect is
used, it limits the amount of wear elongation during the initial operation and ensures wear resistance. 3)Lubrication on the supplied chain should not be wiped off with a cloth or washed off with solvents such as detergents.
3.1 Lubrication Position1)Since wear elongation is caused by wear between the pins and bushings, lubrication must be carried out on these parts. 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. The clearance between the bushing and the roller should also be done at the same time.
3.2 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 for corrosion preventive purposes. The end fit-
ting connection should also be 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, some protective
cover should be attached the chain. If this occurs, moisture must be completely removed and the chain must be well lu-bricated and covered with thick grease.
3.3 Recommended Lubrication1)SAE No. (Table 1)
2)Lubrication in high or low temperature environments.Please consult Tsubaki.

LubricationSystem Quantity of Oil
A
I
Oil is applied with an oilfiller or brush in the gapbetween the pin link andinner link clearances onthe slack side of thechain.
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.
II
A simple case can beused. Oil from the oilcup is supplied by dripfeeding.
Apply about 5 - 20 drops of oil per minute forevery strand of chain. Actual quantity depends onthe chain speed.
B
The chain is installed ina leak-free casing.
Chain should be submerged in oil 6 to 12 mm. 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.
Install the slinger disc ina leak-free oil casing. Oilis splashed on thechain. The circumfer-ence speed should beat least 200 m/min. If thewidth of the chain isgreater than 125 mm,attach slinger discs toboth sides.
The bottom of the slinger disc should be loweredto a position 25 mm from the surface of the oil.The chain should not pass through the oil.
C
Use a leak-free casing.A pump is used tocirculate the oil, which isthen cooled. Thenumber of supply holesshould equal Z+1,where Z is the umber ofstrands of chain.

In the following cases, the slack should be about 2% of thespan.
(1) Vertical drive or close to vertical drive (tensioner is re-quired)
(2) Center distance between two shafts is greater than 1m.
(3) Chain is operated under heavy load and frequentstarts.
(4) Chain drive is suddenly reversed.
3)Roller chain tends to slightly elongate (about 0.05%) aftera few dozen hours following commencement of use. Thisis caused by all the contact surfaces trying to become fa-miliar with each other. This elongation causes excessslack, so the amount of slack needs to be adjusted ac-cordingly. Please use a tensioner if the system has beendesigned for it. If, on the other hand, a tensioner is un-suitable, adjustment of the slack is achieved by movingthe shafts. The chain will have now been used well, soelongation will significantly decrease.
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 following important points cor-rectly. 1)Check the horizontal specification with a level. Adjust the
shafts so that they are horizontal to within ± .
2)Check the parallelism with a scale. Adjust the shafts sothat they are parallel to within ± = ( ).A – B

4. RS Roller Chain Installation and Layout
4.1 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 is possible if the speed is very slow. Chain lap on thesmall sprocket must be at least 120° and at least 90° in thecase of lifting chain.
4.2 Distance between shaftsSprockets can be separated by any distance as long astheir teeth do not touch. Optimum distance is 30 to 50 timesthe pitch of the chain. However, the distance should be upto 20 times the pitch of the chain when there is a fluctuatingload.
4.3 Amount of Slack1) It is not necessary to apply initial tension to roller chain
like V/horizontal belt drives. In general, roller chain isused with a suitable amount of slack. If roller chain isstretched too much, the oil film between the pin andbushing will be torn and damage to the roller chain andshafts will be accelerated. On the other hand, too muchslack will cause the roller chain to vibrate, or ride up onthe sprocket teeth resulting in damage to both the rollerchain and the sprocket.
2)Generally, the slack of roller chain should be on the lowerside. Adequate slack is calculated by moving the chainby hand in a downward direction from the center. Thechain slack that you move by hand (SS’) should be about4% of the span (AB) (Ex. The amount of slack when spanlength is 800 mm would be 800 mm × 0.04 = 32 mm).

2) When chain speed is fast and load fluctuatesThe natural vibration frequency of roller chain and theshock cycle of pumping machinery, or chordal action(up and down movement) of roller chain may attune,causing the roller chain to vibrate. In this case, aguide shoe (made of NBR or EPDM), etc. is used inorder to stop the shaking and prevent vibration.
3) When the center line is verticalInstall a tensioner that can automatically eliminate theextra chain slack. If the driving shaft is on the bottom,a tensioner must be installed.
4.6 Installation of Lambda Curved Chain1)Guide Installation
Lambda Curved Chain has a greater degree of freedomwith regard to the clearance between the pins and bush-ings compared to standard chain. Therefore, a chainguide should be installed to ensure that the chain directlyengages with the sprocket.
2)Minimum Radius (r)The R dimension of the guide should be greater than theminimum radii shown in the following table.
3)Correct the parallelism of the sprockets using a straightedge (or scale). Align the sprocket faces within the toler-ances shown below according to distance betweensprockets.
4)Sprockets are fixed to shafts using Power Locks, LockSprockets, and keys (colors and bolt sets, etc. if re-quired).
4.5 Layouts ( used in the figures below denotes thedrive side)
1)General LayoutsWhen designing the roller chain drive, the centerline ofboth sprockets should be close to horizontal. If installa-tion is close to vertical, it is desirable to install an idler ora guide shoe because even slight elongation can causethe chain to come off the sprocket. The angle of inclina-tion should be kept within 60°.
2)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 thechain feels tense.
When the center distance is long, chain slack is ad-justed by installing an idler, which supports the rollerchain.
Clearance between chain and guide should be 2 to 4 mm

5. 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.
If you notice any of these conditions, do not begin operation. Correct any problems before proceeding any further.
6. Roller Chain Inspection1)In general, life of roller chain is said to be used up when parts are damaged or when there has been 1.5% wear elonga-
tion. (Refer to 6) of point 5) in 6.3) Try to replace the chain before this kind of situation occurs.2) If roller chain selection and operating conditions are suitable, you can expect rather long life and unexpected trouble
from the chain. However, wear will progress between the pins and bushings after a long period of time, so we have de-scribed some matters below, which should be noted and inspected.
6.1 Inspection Checklist (Table 3)
Procedures Method Inspection Items Reference pagefor details
Step IVisually check the chainduring operation and lookfor any abnormalities.
1. 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 the
sprockets.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.
Inspectionpoints are onthe followingpages andon thetroubleshooting andproblem-solvingpages
Step II
Stop the chain andcarefully inspect eachpart of the chain andsprocket.
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 of
the end bolts and the wear of the connecting link plate pins. Also checkfor proper installation at the same time.
Step III
In order to investigate inmore detail, remove theroller chain and inspect itvisually or check it withmeasuring instruments.
1. The inspection items are identical to those in Step II, however,everything is checked in more detail.
99
6.2 Inspection IntervalsRegular inspection of roller chain is recommend at one-month intervals. Inspection should be carried out at shorterintervals in the following cases.1. Special or corrosive environments2. High speeds with sudden stoppage3. Lifting or indexing operations
6.3 Inspection requirements for ordinary transmission1) Inspecting condition of lubrication
1) While the chain is driving, check to see if there is lu-brication in the clearance between the outer link plateand inner link plate. Also check if the chain or rotatingdisc is 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 betweenthe link plates.
3) When the chain is removed, connecting link pins andthe edge of the inside of the bushings should bechecked. If there 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 put on the chain, there is a strong possibility of fa-tigue breakage of the link plate. It is difficult to noticeinitial cracking from fatigue breakage simply from ex-ternal observation.
2) Usually, a crack develops at the edge of a hole or atthe side of the link plate, as shown in the illustrationsbelow. The presence of cracks should be checkedcarefully. Fatigue breakage progresses little by little,so it can be noticed if close attention is paid.
3) When wear occurs from sliding between the edges ofthe plates and the guides, it is necessary to adjust theposition of either the chain or the guides. The allow-able wear on the link plates is limited to 5% of theirheight.
3) Inspection of pinsWhen the pins rotate, the roller chain must be completelyreplaced with new chain. This also applies to the connect-ing pins. By removing the connecting parts it is possible tosee the conditions of wear and rust on the surfaces of thepins.
4) Inspection of the rollers1) As with the link plates, if rollers are also subjected to
loads over the maximum allowable load, the repeatedimpact load between the chain and the sprocketsmay cause fatigue breakage to occur. The rollershould be checked in the 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 paidto the above.Furthermore, with high-speed operations, even if for-eign objects do not interfere with engagement, cracksmay appear from the impact with the sprocket teeth.
3) Chains damaged from fatigue breakage of the rollersmust be completely replaced, because each part hasreceived the same amount of repeated load.
4) Also check if the roller rotation is poor.
5) Inspection of the sprockets1) Chain and sprocket engagement can be checked by
observing the roller and surface of the teeth. Properengagement is when the contact area is uniform withpoint A in the illustration. If the contact area is lop-sided or the sides of the teeth are wearing away(point B), this may have been caused from improperinstallation of the sprockets or twisting of the rollerchain. In this case, rechecking/readjustment is neces-sary.
2) The normal point of impact is slightly up from thetooth bottom. However, when initial tension is appliedto the chain and tension remains on the slack side,the roller will slightly touch the tooth bottom. However,point A receives the strongest impact.

3) When idlers or tensioners are used, the contact areawill be the center of the tooth bottom.
4) When wear on the teeth reaches the values in the fol-lowing table, lifespan of the sprocket has beenreached. For a sprocket with induction hardenedteeth, the lifespan is reached when the hardened lay-er has been removed.
5) If a new roller chain is run on a worn sprocket, thechain will wear at a faster rate than normal. In thiscase, when replacing the chain, replacement of thesprocket is also recommended.
6) Inspection of chain elongation1) Chain elongation is caused not by deformation of the
link plate, but by wear on the pin and bushing.Therefore, the remaining chain life can be estimatedby periodically measuring the chain elongation.
2) Measuring chain elongation(1) The chain should be measured whilst stretching it
slightly to eliminate any slack.(2) Measure the distance of the inside (L1) and outside
(L2) of the rollers at both ends of the measured linksusing a vernier, to get a measurement (L).
(3) When measuring, use at least 6 to 10 links to helpkeep any measuring error down to a minimum.
(4) Finding the chain elongation
(5) For multi-strand roller chain, the measurement iscarried out in the same way as for single strandroller chain of the same pitch.
(6) The limit of usage based on roller chain elongationfor a smooth transmission is as follows.
Chain elongation (%) = Measured length – Standard length × 100Standard length
Standard length = Chain pitch × Number of links
L = L1 + L2

(7) Dimensions for evaluating standard length (chainpitch × number of links) and 1.5% elongation areshown in Table 6 below.
(8) When the length of the roller chain cannot be mea-sured with a vernier, a tape measure may be used;however, measurements need to be taken over asmany links as possible to reduce measuring error.
(9) Lifespan of Lambda (Λ) / X-Lambda (X-Λ) rollerchain. When chain elongation of Lambda RollerChain reaches about 0.5% it may be losing its lubri-cating properties. This may be determined by theadhesion of red wear particles between the platesand the occurrence of articulation stiffness. Whenthis occurs, the life of the chain has been reached.
6.4 Inspection of lifting and shuttle traction1)This should be carried out with the same requirements as
for ordinary transmission shown in item 6.3.2)It is important to check the lubrication of the connecting
parts between the roller chain and end brackets whereend brackets are installed, as well as the parts where theroller chain winds around the sprocket. (Refer item 3.2 onpage 94)
3)The parts where the roller chain bends around thesprocket should be checked when inspecting the wearelongation of the roller chain.

4) Inspection of twisting and side bending of the rollerchain.If partial twisting or side bending of the chain occurs, thecomplete roller chain should be replaced. (Fig. 29)
5)End bracketsCheck for damage by deformation of the hole due towear. If the hole is damaged or deformed, replace the endbracket immediately. The clearance on the pinhole of thebracket affects the life of the roller chain and should bekept to a minimum.
6.5 StorageAvoid storing spare parts, such as a roller chain, sprockets,and end brackets, in high temperature/high humidity anddusty environments. Also, when storing roller chain that hasbeen removed, wash the roller chain and then apply lubri-cation. After the roller chain clearances have been suppliedwith a sufficient amount of lubricant, wrap the chain ingrease paper completely before storing away.

7. Cautions on Use in Special EnvironmentsAs a general rule, roller chain should be used in a clean air flow; however, when used in a special atmosphere, referenceshould be made to the various items that follow.
7.1 Use in wet conditionsIf the chain is used in a sterilizing machine or water screen, for example, where the chain is splashed with water or goesthrough heated vapor, the following problems may occur.1)An increase in abrasive stretch due to improper or insufficient lubrication.2)Decrease in fatigue strength from rust and corrosion (pitting) of the chain.
1) Countermeasures(1) Reduce bearing pressure using a larger sized chain to improve wear resistance.(2) Use corrosion resistant roller chain for rust prevention.
7.2 Use in acidic or alkaline conditionsIf roller chain is exposed to acids or alkaline conditions, such as battery acidand liquid 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-
chemical corrosion may occur.6)There are also circumstances where even stainless steel roller chain will cor-
rode. Fig. 31 shows an example of chain that was used in a plating appara-tus. The chain fell to pieces within one month due to the affect of the acid.1) Countermeasures for embrittlement fractures (Stress corrosion cracking)
(1) Adopt a brittleness countermeasure that lowers crack susceptibility.(2) Install a cover or casing to prevent acids or alkalis from contacting the
chain.(3) Adopt a high-grade material with anti-corrosive properties.
2) Countermeasures for corrosion(1) Use surface-treated chain.(2) Install a cover or casing to prevent acids or alkalis from contacting the
chain.(3) Adopt a high-grade material with anti-corrosive properties.
In general, embrittlement fractures (stress corrosion cracking) occur around thelink plate holes. This is the area where the pin and bushing are press-fitted tothe link plate having the highest concentration of stress. Cracks are generatedeven when there is no tension on the chain. Roller chain in general is more sus-ceptible to acids than alkalis, and in special cases, embrittlement fractures(stress corrosion cracking) are generated by seawater or pit water.
7.3 Use under conditions where abrasion is a problemIf the chain is exposed to strong abrasive materials that promote wear such as sand, coke and metal particles, the followingproblems may occur.1)When the abrasive materials penetrate between the pins and bushings, chain wear is promoted and poor articulation oc-
curs.2)When the abrasive materials penetrate between the bushings and rollers, chain wear is promoted and poor roller rotation
occurs.3)When the abrasive materials penetrate between the link plates, poor articulation occurs.
1) Countermeasure(1) Apply a dust-protection casing.(2) Remove foreign particles by regularly washing the roller chain.(3) Reduce bearing pressure using a larger sized chain to improve wear resistance.(4) Increase abrasion resistance by applying special processing to the parts of the chain where abrasion is a problem.

8.2 Link Plate Related
Symptom Possible Causes Remedy
Excessively large shock load. Reduce shock loads by making the start-up, stopping, andother actions smoother (installing a shock absorber, etc.).Increase the size or number of chains.
Vibrations in the chain. Install an anti-vibration device (for example, tensioner oridler). Refer to “Excessive vibration in chain” page.
Large inertia in the driven machine(excessive load).
Increase the size or number of chains.
Corrosion. Replace with a new chain. Install a casing to protect thechain. Otherwise, periodically clean the chain.
Cracks in the linkplates (fatigue), whichare perpendicular tothe direction of pull.
Loads are greater than allowable. Remove all large or excessively repeating loads. Otherwise,increase the size or number of chains. Replace with a newchain.
Deformation of link plateholes.
Excessive load. Remove the cause of the excessive load. Replace with a newchain.
The chain is being used in an acidic oralkaline environment. (This is notcaused by a repetitive load).
• Replace with a new chain. Install a casing to protect thechain from the environment.
• Consider a chain with a high resistance to corrosion stresscracks. (Please consult Tsubaki.)
Breakage of link plate.
Corrosion stress cracksappear, usually asbow-shaped cracks inthe link plate.
(1) Static fracture.Stretching the link plate witha tensile load beyond itsbreaking load will cause itto stretch 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.

Replace with new chain. Improve the lubrication or loadingconditions.
(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. Re-check the 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 whenthe surface of the pin has corroded. This type ofphenomenon occurs quite easily.

6) When ordering a replacement chain.1) When the roller chain size is unknown.
(1) Roller chain specification. (It is important to confirmthe specifications such as powerful series type andmaterial. Please confirm with the equipment maker.)
(2) Since the roller chain link plates have been markedwith the roller chain size and specification, pleaseconfirm this information.
(3) Please measure the roller chain pitch, roller diameter,width between inner links and plate thickness.
2) When the sprocket number is unknown.(1) Chain No. and number of strands.(2) Sprocket type(3) Shaft hole diameter (Not required when shaft hole
processing is carried out in your company)(4) Number of teeth(5) Boss diameter and boss length (Only for special
types).(6) Whether or not the teeth ends have been hardened.(7) Marking
Additionally, when the roller chain number is also un-known, please provide the following data in addition to(1) ~ (7) above:(8) Width of teeth (T)(9) Tooth bottom diameter (DB) (DC for an odd number of
teeth)
