RS ROLLER CHAIN RS ROLLER CHAIN IMPROVED ANSI RS Roller Chain RS ROLLER CHAIN RS RS4 Superior Impact Resistance Tsubaki chain has increased tensile strength and approximately % greater impact resistance than ANSI standard chain. The Stress-Strain Curve below illustrates how this extra Tsubaki strength provides greater protection against dangerous ultimate strength failure. Greater Fatigue Strength When you compare Tsubaki chains for fatigue strength performance, the facts put Tsubaki out in front. Compare the S-N Curve below for Tsubaki chains and see how the competition fades. Higher Horsepower Rating Tough Tsubaki chains not only last longer but stand up to higher horsepower ratings. In fact, RS5 and RS4 through RS4 withstand 5% higher horsepower ratings. The improvement comes from a Tsubaki exclusive ring coining process for the slip fit connecting link and special processing on the two-pitch offset links. That means you can choose a smaller, less costly chain yet more than fulfill your requirements.

RS ROLLER CHAIN Assurance of Greater Fatigue Strength The wider waist of Tsubaki link plates ensures greater fatigue strength for all chain sizes. Fatigue strength (max. allowable load) of each size can be found in this catalog. 5) Improved Tsubaki roller chain sizes RS8, RS, RS, and RS4 last up to % longer even without re-lubrication. A Tsubaki innovation a lube groove (patent pending) on the inner surface of the bushing retains the factory prelubricant oil. Heat Treatment Ensures Durability Chain durability depends to a great extent on the heat-treatment of the various parts. The use of the most advanced heat-treatment methods and equipment guarantees that Tsubaki roller chains are highly durable. Tsubaki Other Brands Longer Wear Life & Less Initial Adjustment ) Tsubaki has decreased initial stretch to.% and increased wear life by as much as 4% over the competition. Where initial elongation is a problem, as in precision applications or when you simply demand the best, Tsubaki roller chain is the solution. ) Our original prelubricant minimizes stretch to enable a vast increase in the chain's wear life. Elongation Lube Groove Competition Former Driving Hours Tsubaki Improved Heat Treatment Prelubrication A special lubrication is applied by Tsubaki to bearing surfaces by hot dipping to extend chain life and reduce maintenance costs. ) Tsubaki bushings are "curl formed" from high quality cold rolled alloy steel into a completely cylindrical shape with uniform wall thickness. Shot Peened Parts Link plates and rollers are shot peened for greater fatigue strength. Perfectly cylindrical inside bushing wall 4) Micron control has enabled Tsubaki to produce perfectly straight bushings and significantly reduce stretch during initial operation. Factory Preloading Tsubaki roller chains are continuously preloaded on multi-sprockets after final assembly as shown below. This results in minimum initial stretch. Prelubrication A Completely Automated Manufacturing Process The manufacture of Tsubaki roller chains employs advanced, automated techniques. The specialized equipment used in each process ensures that all parts are uniform and high quality. The photo below shows the automated positioning of bushings.

RS ROLLER CHAIN APPLICATIONS Roller chains can be operated at speeds of up to, rpm. Even at high speeds, chain drive is quieter and smoother than a gear drive. You never have to worry about slippage as you would with a belt. Roller chains are inherently elastic. Compared with gear drives, they soften shock and absorb vibration. They can be used in machines which are subjected to great shock or which constantly move or vibrate. Both the machine's body and bearing parts are protected against damage. For accurate high speed drives... automobile engines For high speed and heavy load drives... oil-well drilling equipment For heavy shock... draw benches For long center distance drives... container straddle carriers For precision drives... marine diesel engines For severe conditions... tilting tables A- For heavy shock... crawler drills For multi-shaft drives... roller tables For high speed operation... pump drives
RS ROLLER CHAIN CONNECTION OF RS ROLLER CHAIN IMPROVED Roller chain is normally used as a continuous length with a connecting link, resulting in an even number of pitches. Connecting Links Standard connecting links are used when RS roller chain is operated under normal conditions. For severe applications, press fit connecting links are suggested. In either case, a spring clip connecting link is used for RS roller chains of sizes RS6 or smaller, a cottered connecting link for sizes RS8 to RS, and a spring pin connecting link for RS4. A cottered type connecting link is used for three to six strands of RS4 to RS6. A cottered type can be provided for single and double strands of RS4 to RS6 upon request. Standard connecting links have a slip fit cover plate. The wider waist of Tsubaki's cover plates provides higher fatigue strength. Installation of press fit connecting links may be less convenient than that of standard connecting links, but performance is better. Press fit connecting links should be used in extremely high-speed or heavy duty applications. The slip fit connecting links on improved Tsubaki chain have 5% greater fatigue strength. These connecting links are ring coined, which means improved capacity for your application. If a continuous length has an odd number of pitches, an offset link must be used. However, the use of offset links should be avoided. Offset Links Both two-pitch offset links and one-pitch offset links are available for RS roller chains. Tsubaki's redesigned link plate and improved manufacturing process make our two-pitch offset links stronger than ever. The two-pitch offset link is a combination of a roller link and an offset link connected with a riveted pin. The connecting link can be attached to either side of a two-pitch offset link. One-pitch offset links are very handy, but pin and offset link plates have to be slip-fitted. One-pitch offset links are also weaker than plain chain and two-pitch offset links. Therefore, one-pitch offset links are not suggested, especially for frequent on-and-off operation, heavy impact loads, and high-speed driving. Note: Only two-pitch offset links are available for RS5. Roller Chain A roller chain consists of roller links and pin links connected in series. Roller Link Plate Roller Link Plate Roller Link Pin Bushing Roller Pin Link Plate Pin Link Plate Pin Link A-4

Heavy Series Heavy Series roller chains differ from the ANSI standard series in the extra thickness of the link plates and the extra length of the pins. These link plates have the same thickness as the link plates of ANSI chains having the next larger pitch. The thicker link plates provide greater capacity (approximately %) for absorbing shock loads.

CHAIN DRIVE SELECTION Horsepower Rating The horsepower rating in Table IV on page A-4 is based on the following conditions: ) The chains are operated under ordinary conditions. The ambient temperature range must be between 5 F and 4 F. They should not be used in an atmosphere in which abrasive dust or corrosive gas is present or where the humidity is high. ) The two transmission shafts are in a horizontal position, and the chains are properly installed. ) The suggested lubrication system and oil are used. 4) The load does not change significantly during transmission. The Service Factor given in Table I should be taken into account when the chains are used under various operating conditions. The load conditions will affect the life of the chain. 5) The increase in the horsepower rating of multiple strand roller chain cannot be calculated simply by multiplying the horsepower rating of one strand by the number of strands, since the load on each strand is not exactly the same. In order to estimate the service life of a multiple strand chain, the Multiple Strand Factor given in Table II must be used. When the chain length is pitches and the above conditions are met, a service life of approximately 5, hours can be expected. Procedures for Selecting Roller Chain ) The following factors must be considered when selecting roller chain. a. Source of power b. Driven machine c. Horsepower to be transmitted d. RPM of driving and driven shafts e. Diameter of driving and driven shafts f. Center distance of the shafts ) Use Table I to obtain the Service Factor. ) Multiply the horsepower value by the service factor to obtain the design horsepower value. 4) Use Table IV on page A-4 and the horsepower ratings tables on pages A-6 to A-9 to obtain the appropriate chain number and the number of teeth for small sprockets. Refer to the number of revolutions of the high speed shaft (the driving shaft when the speed is reduced; the driven shaft when the speed is increased) and the design horsepower value. For smoother chain drive, a smaller pitch chain is suggested. If a single strand chain does not satisfy the transmission requirements, use a multiple strand chain. If there are space limitations, a multiple strand roller chain with a smaller pitch may be used. 5) After determining the number of teeth necessary for the small sprocket, refer to the Sprocket Dimension Table (pages A-79 to A- 8) to check if the sprocket diameter satisfies the space limitations. 6) The number of teeth for the large sprocket is determined by multiplying the number of teeth for the small sprocket by the speed ratio. More than 5 teeth on the small sprocket is suggested. The number of teeth for the large sprocket should be less than. By reducing the number of teeth for the small sprocket, the number of teeth for the large sprocket can be reduced. 7) For temperatures below 5 F, see the Environmental Temperatures and Points of Concern Table on page B-8.

RS ROLLER CHAIN A- Example Step Data Required. Type of application: Centrifugal Blower. Shock Load: Small load fluctuation. Source of Power: Motor 4. HP to be transmitted: 4 hp 5. Drive shaft: Diameter inches, 75 rpm Driven shaft: Diameter inches, 5 rpm 6. Center distance: Less than 9 inches 7. Space limitation: Less than inches Step Use Table I to determine the service factor. Service Factor SF =. Step Obtain Design HP Design HP = (HP to be transmitted) SF = 4 hp. = 4 hp Step 4 Obtain the chain number and the number of teeth on the small sprocket from the Roller Chain Selection Table (page A-4) referring to the above 4 hp and 75 rpm. Then check it by referring to the Horsepower Rating Tables (pages A-6 to A-9).. According to the horsepower rating, the best choice would normally be a single strand of RS8-7 teeth. Since the speed ratio is / (5/75 rpm), the necessary number of sprocket teeth would be 7 for the small sprocket and 5 for the large sprocket. But, as the outside diameters are 5.94 inches for 7 teeth and 6.8 inches for 5 teeth (refer to sprocket dimensions on pages A-79 to A-8), it exceeds the space limitation of inches (5.94 + 6.8 > inches). Therefore, these sprockets are not suitable.. As a single strand chain is not suitable, a multiple-strand RS6-, and 66 teeth would be possible. But this combination is not suitable due to the space limitation again (5.67 + 6.8 > inches).. For triple strand, RS6-, 5 and 45 teeth would be possible. The sprockets diameters are.9 inches and.8 inches respectively, the sum of which is less than inches. The horsepower rating of a 5- tooth sprocket for the RS6- should be confirmed by the horsepower rating for the RS6 (see page A-). The horsepower rating of a 5 tooth sprocket is 5. hp at 7 rpm and 7 hp at 8 rpm. So the horsepower rating at 75 rpm is about 6 hp. Since 6 hp is for a single strand chain, the horsepower rating must be multiplied by a multiple strand factor of.5 for a triple strand (see page A-). Therefore, the horsepower rating of RS6-, 5 teeth at 75 rpm is 4 hp (6.5 = 4). Step 5 Refer to Sprocket Section (C) in this catalog to check the diameter of the bore. A 45-tooth sprocket meets the necessary requirement, but since the maximum bore diameter (.87 inches) of a 5-tooth sprocket is smaller than the drive shaft diameter of inches, it can t be used. A 6-tooth sprocket with a maximum bore diameter of inches must be used. Check again that the outside diameter, 4. inches for 6 teeth and.89 inches for 48 teeth, is less than the space limitation (4. +.89 < ). A combination of RS6-, 6 and 48 teeth must be used to fulfill all the necessary requirements. Selection for Slow Speed When the chain speed (S) is less than 6 ft./min., select the RS roller chain that is one size smaller than the chain chosen from the horsepower rating method mentioned above.. Tentatively select the chain and sprocket from Table IV (page A-4) and proceed by using a one-sizesmaller chain and its sprocket with the number of teeth close to the sprocket selected above. Be sure to confirm that the sprocket meets the application requirements such as bore diameter and space limitation, etc.. Calculate the chain speed from the number of teeth on the driving sprocket using equation (A). Also check that the speed is less than 6 ft./min.. Calculate the chain tension for the above drive from equation (B). 4. Select the service factor and the chain speed coefficient from Table I (page A-) and Table III. 5. Verify that the chain has maximum allowable load which satisfies equation (C).

Note: Please use press fit connecting links for slow speed chain selection. Table III: Chain Speed Coefficient Chain Speed Less than 5 ft./min. 5 to ft./min. to 6 ft./min.

When exposed to high temperatures, the mechanical properties of the heat treated chain components are lost.. The hardness, and therefore the wear resistance of pins and bushings, is reduced.. At temperatures above 9 F, the rollers and plates lose their hardness and strength. Standard roller chains can be used in temperatures up to 5 F with the following adjustments: Temperature Up to 4 F 9 F 5 F Percentage of Catalog Capacity Rating % 75% 5% For temperatures below 5 F, see the Environmental Temperatures and Points of Concern Table on page B-8.
Table IV: RS Roller Chain Selection Table How to use this table:. Example... Design horsepower 7 hp a) Assume that the RPM of the small sprocket is. Judging from the intersection point of the design horsepower s value of 7 hp and the RPM value of, RS8 and a sprocket with either 7 teeth or 8 teeth can be selected. Sprockets with 7 teeth are more economical than those with 8 teeth. b) Assume that the RPM of the small sprocket is. An RS6, 5-tooth sprocket is appropriate from the intersection point in the same manner as above. The line for RS5-4 teeth can also be seen near the intersection of 7 hp and rpm. Therefore, either RS6-5 teeth or RS5-4 teeth can be selected. This table is used to make a tentative selection. The Horsepower Rating Tables should be used to determine the most appropriate chain and sprocket.. Horsepower lines of, 4 and -tooth sprockets are shown only in the high speed range on the right hand side of the above chart. When checking the horsepower line of these sprockets, make a line parallel to the other lines on the left hand side of the dotted line for RS5-4 teeth.. When using a chain in the white part on the right side of the table, please consult with Tsubaki. 4. When the chain speed is less than 6 ft./min., it is more economical to select your RS roller chain by the selection method for slow speed drives (see page A-). A-4

V CLASS CHAIN V Class Chain for Maximum Fatigue Resistance Tsubaki V Class roller chain is designed for high speed and high shock load applications. V Class chain is designed to withstand the heavy loads found in oil field, mining, logging, and ball mill applications. Pump Drive A- Ball Mill
Benefits Semi-Press Middle Link Plates Middle link plates have a shorter pitch than the pin link plates creating a contact fit. This allows for easier cutting and assembly of the chain without sacrificing its horsepower rating. Meets API 7F Specification Tsubaki V Class chain is manufactured according to the API specification 7F, Oil Field Chain. Heat-Treatment ball-drift shot-peening Superior Impact Resistance The pin surface is carburized and hardened by Tsubaki heat-treating techniques for superior impact resistance. This results in greater breaking strength and increased chain wear life compared to ANSI standard chains. Greater Fatigue Strength Link plates are ball drifted after heat-treatment for greater fatigue strength. This results in a % increase in chain life compared to our ANSI standard chains. High Speed Durability Rollers, precisely manufactured, are shotpeened after heat-treatment to give them superior fatigue life and high speed durability. A-
V CLASS CHAIN Note: Shepherd s crook type cotter ( ) will be supplied unless otherwise specified. Cotter Pin Type Connecting Link (The pin and link plate are press-fitted.) Four-pitch Offset Link BCL (bushed type connecting links) are employed for multiple strand chain. The cover plate is designed for a snug press-fit on the pins for use on drives that are subjected to high speeds and heavy shock loads. Removal of the press-fitted pin may be less convenient than that of ordinary connecting links but better fatigue strength is provided. Press fit offset link plates are used. It is suggested that offset links be used only when an odd number of links cannot be avoided. A-

SUPER CHAIN Super Chain Proven Performance ANSI standard roller chains are widely used in various industries. To meet the insistent demands of heavy industry, construction and agriculture, stronger and higher performing chains which can replace the corresponding ANSI standard chains are necessary. Tsubaki offers a line-up of Super and Ultra Super Chains which will solve your specific driving and conveying problems relating to heavy shock load and/or space limitations. SUPER ROLLER CHAIN SUPER 8 4 High fatigue and tensile strength allow the selection of a chain one size smaller than would be required with standard chain. Pins constructed of high toughness steel give this chain exceptional ability to absorb shock loads. The link plate holes are ball drifted to obtain high fatigue strength. A-5
If you have a problem like breakage of pins due to heavy shock loads, we suggest that you use either the T Series or the HT Series. If you have problems such as fatigue breakage of link plates, generally poor performance, or a space limitation, we suggest that you use the Super Series, Super-H Series or Ultra Super Series. You may be able to use the next smaller size chain or even a chain two sizes smaller. T Series T Series chains have greater shock load resistance and higher ultimate tensile strength than comparable ANSI standard roller chains. This is accomplished by using thru hardened pins. The dimensions of the chains are identical to ANSI standard roller chains. HT Series HT Series chains have a greater ultimate tensile strength (plus 5-%) than ANSI standard roller chains by using thru hardened pins and link plates of the next larger chain size. These chains also provide greater shock load resistance. The dimensions of the chains are identical to those of the ANSI Heavy Series standard roller chains. Super Series The dimensions of Super Series Chain are identical to those of ANSI standard roller chain. Super Series Chain has a wider waist link plate than our standard chain and special manufacturing techniques are used to produce the pitch holes. After heat treatment, the holes are then ball drifted for greater fatigue strength. The pins are thru hardened for greater shock resistance. Because of this, Super Series Chain has a Maximum Allowable Load 5-% higher than our standard RS roller chain. Super-H Series Super-H Series Chain has the same wide waist as Super Series. The link plate thickness is identical to those of the ANSI Heavy Series roller chains. The same special manufacturing techniques used in Super Series Chain are used to produce the pitch holes. The pins are thru hardened. Because of this, Super-H Series Chain has an even higher Maximum Allowable Load than the Super Series. Ultra Super Series Tsubaki Ultra Super Series has a greater ultimate tensile strength and allowable load than any other roller chain we manufacture. With the Ultra Super Series, a chain up to two sizes smaller than standard can be selected. A-6

S= P N n (ft./min.)..........(a) T=, HP (lbs.)..........(b) S T Service Factor Chain Speed Coefficient Maximum Allowable Load..................... (C) S: chain speed (ft./min.) P: chain pitch (inch) N: number of teeth of driving sprocket n: RPM of driving sprocket T: chain tension (lbs.) HP: horsepower to be transmitted (HP) The following three lubricating systems are suggested: System A System B System C Manual lubrication The oil is applied with an oil can or brush in the gap between the pin and roller link on the slack side of the chain. It should be applied about every eight hours or as often as necessary to prevent the bearing areas from becoming dry. Suitable chain speed is to be below 5 ft./min. Drip lubrication A simple casing can be used. The oil is supplied by a drip feed. Each strand of chain should ordinarily receive 5 to drops of oil per minute. The amount is increased as the speed increases. Suitable chain speed is from 5 to ft./min. Oil bath lubrication The chain is installed in a leak-free casing. The oil depth of h should be /4 to / inch deep. If the oil is too deep, it will be adversely affected by the heat generated. Suitable chain speed is from to 6 ft./min.

BS/DIN ROLLER CHAIN CHAIN DRIVE SELECTION SELECTION PROCEDURE ) The following factors must be considered when selecting roller chains for transmission needs. The power to be transmitted. The speed and the diameters of the driving shaft and the driven shaft. The distance between the centers of the shafts. ) Use Table I to obtain the service factor. (The Service Factor table refers to the type of machine and source of power.) ) Multiply the HP value by the service factor to obtain the design HP value. 4) Use Table III page A-5 to obtain the appropriate chain number and the number of teeth for the small sprocket by referring to the number of revolutions of the high speed shaft (the driving shaft when the speed is reduced; the driven shaft when the speed is increased) and the design HP value. For a smoother chain drive, a smaller pitch chain is suggested. If a single strand chain does not satisfy the transmission requirements, use a multi-strand chain. If the distance between the shafts and the diameter of the sprockets must be relatively small due to space considerations, a multiple strand roller chain with a smaller pitch may be used. 5) After determining the number of teeth for the small sprockets, confirm if the sprocket will meet the shaft diameter requirements. 6) The number of teeth for the large sprocket is determined by multiplying the number of teeth for the small sprocket by the speed ratio. While it is preferable that the number of teeth for the small sprocket be greater than 5, it is suggested that the number of teeth for the large sprocket not exceed. By reducing the number of teeth for the small sprocket, the number of teeth for the large sprocket can also be reduced.

Table III: BS Roller Chain Selection Table Example Data:. Type of application: Centrifugal Blowers. Source of power: Electric Motor. HP to be transmitted: 4 hp 4. Driving shaft: 6 rpm 5. Driven shaft: rpm 6. Center distance: 9 inches 7. Space limit: Max. 4 inches Step Use Table I and determine the service factor. Service factor (SF):. Step Obtain design HP Design HP= HP to be transmitted SF = 4 hp. = 4 hp Step Obtain the chain size and the number of teeth of the small sprocket from the selection table for 4 hp and 6 rpm. The selection table is based on the following conditions: ) The chains are operated under ordinary conditions. The ambient temperature range is between 5 F and 4 F. They are not to be used in an atmosphere where abrasive dust or corrosive gas is present or when the humidity is exceptionally high. ) The two transmission shafts are in a horizontal position and the chains are properly installed. ) The suggested lubrication system shown on Table IV is used. 4) The load does not change significantly during transmission. The Service Factors given in Table I are used when the chains are used under various operating conditions. The load conditions will affect the life of the chain. The increase in the horsepower rating of multiple-strand roller chains cannot be calculated simply by multiplying the horsepower rating of one strand by the total number of strands, since the load on each strand is not exactly the same. In order to estimate the service life of a multiple-strand chain, the Multiple-Strand Factor given in Table II must be used. Note: Refer to page A-77 for details of lubrication system. * * * According to the selection table, the selected chain and sprocket rpms are: (a) RSB- chain and 5-tooth sprocket (b) RS6B- chain and 7-tooth sprocket (c) RS6B- chain and 5-tooth sprocket For (a), the necessary number of teeth for both small and large sprockets are 5 teeth and 75 teeth respectively, since the speed ratio is / (/6 rpm). But the outside diameter of both sprockets, 6. inches for 5 teeth and 8. inches for 75 teeth, exceeds the limitation (6. inches + 8. inches > 4 inches). Therefore, these sprockets cannot be installed. For (c), the necessary number of teeth for both small and large sprockets are 5 teeth (outside dia. 8.4 inches) and 75 teeth (outside dia. 4.4 inches), respectively. It exceeds the space limitation again (8.4 inches + 4.4 inches > 4 inches). For (b), the necessary number of teeth for both the small and large sprockets are 7 (outside dia: 5.9 inches) and 5 (outside dia: 6.8 inches). It satisfies the space limitation (5.9 inches + 6.8 inches < 4 inches). A combination of RS6B-, and 7 teeth and 5 teeth must be used to fulfill all the necessary requirements. Step 4 Use Table IV to determine the lubrication method. Chain speed (S) = P N n = 6 7 = 85 ft./min. System B is suggested. Step 5 Obtain the number of pitches of chain (L). N - N ( ) = N + N + C + 6.8 C 5-7 ( ) = 7 + 5 + 9 + 6.8 9 = 7.5 74 links A-5
ANTI-CORROSIVE / HEAT RESISTANT CHAIN Anti-Corrosive Heat Resistant Chain ULTRA WP CHAIN ULTRA WP chain resists corrosion when exposed to harsh outdoor environments, including seawater. The exclusive ULTRA WP surface treatment process gives the chain its unique matte grey color and provides a protective finish that is more corrosion resistant than Nickel-Plated chains. ULTRA WP chain has the same high maximum allowable load as our standard carbon steel roller chain. NICKEL-PLATED CHAIN Nickel-Plated chains provide acceptable performance where equipment must operate in mildly corrosive environments. 6 AS SERIES AS Series chains are an excellent choice for drives requiring both corrosion resistance and high load capacity. Link plates are made of 4 stainless steel and the round parts are made of hardened 6 series stainless steel. Of all the stainless steel chains offered by Tsubaki, AS Series has the highest load capacity. Use where stainless steel is required by FDA regulations. 4 SS SERIES SS Series chains are made completely of 4 stainless steel. SS Series has an excellent resistance to corrosion & temperature extremes. It is generally considered non-magnetic, although some permeability can be found in these chains. This is caused by the cold working of the components during the manufacturing process. If more complete non-magnetic permeability is required, we suggest our NS Series. 6 NS SERIES NS Series chains are made completely of 6 stainless steel. It is the most corrosion resistant standard stainless steel chain offered by Tsubaki. It also has the highest resistance to temperature extremes, and is sometimes referred to as our non-magnetic series because of its extremely low magnetic permeability. The load capacity of 6 NS Series is equal to that of our 4 SS Series. LS SERIES CHAIN LS chain features stainless steel construction plus an engineered plastic sleeve between the pin and the bushing to make the chain self-lubricating. It is ideal when lubrication is difficult or impossible or in operations that require frequent washdowns. LS chain offers the corrosion resistance of stainless steel in a lube-free chain that will operate well even under water, especially when used in combination with an engineered plastic roller. POLY-STEEL CHAIN Poly-Steel chain is made of molded engineered plastic with 4 stainless steel pin links. This combination effectively incorporates the advantages of both materials into one chain. Poly-Steel chain from Tsubaki has superior wear life, excellent corrosion resistance, and requires no lubrication. This design provides a quiet, lightweight chain for economical solutions to difficult application problems. TITANIUM TI SERIES TI Series chains are made completely of Titanium. Available in sizes RS5TI - RS6TI, TI Series brings the unique properties of Titanium to roller chain applications, specifically extreme corrosion resistance in a lightweight chain. Available on a made-to-order basis in the same dimensions as the 4 SS Series. Call Tsubaki for further details. A-5

LEAF CHAIN Leaf Chain Leaf chains generally have greater tensile strength than roller chains, and run over sheaves rather than sprockets. They are most often used as counterweight chains for machine tools, elevator and oven doors, fork lift truck masts, spinning frames and similar lifting or balancing applications. BL series can, in most instances, replace the older AL series Leaf chains; consult Tsubaki for interchange information. These chains are supplied with male or female terminations to allow addition of various clevises as desired. A-6

GENERAL CAUTIONS. Use lengths of factory assembled chain. Do not build lengths from individual components.. Do not attempt to rework damaged chains by replacing only the components obviously faulty. The entire chain may be compromised and should be discarded.. Never electroplate assembled Leaf chain or its components. Plating could result in failure from hydrogen embrittlement. 4. Welding should not be performed on any chain or component. Welding spatter should never be allowed to come in contact with chain or components. 5. Leaf chains are manufactured exclusively from heat treated steels and, therefore, must not be annealed. If heating a chain with a cutting torch is absolutely necessary for removal, the chain should not be reused. 6. Joining chains together should only be done by the chain manufacturer. 7. The Minimum Ultimate Strength of a chain means the minimum load at which it will break when subjected to a destructive tensile test. It does not mean working load. 8. Chains from different manufacturers should not be used in the same application. A-

Wrench chain Extra long pins serve as tension linkages to provide a secure hold for pipe wrenches. Laminated Block chain Manufactured with 4 stainless steel, it directly replaces solid block chain in light load, low speed applications. Agriculture chain With higher tensile strength, longer life, and smoother operation than malleable chains, Tsubaki offers MR and RF types for agriculture applications. A-69
Lube-Free Chain For use where normal lubrication is not practical, i.e., food processing equipment, packaging machines, printing and binding equipment, and textile machines. High quality lubricant is impregnated into the sintered metal bushings. Joint movement between the pin and bushing releases the necessary volume of oil to the pin surface and other parts, thereby minimizing chain elongation and eliminating the risk of chain seizure from insufficient lubrication. See our Drive Series LAMBDA (page A-5) and Conveyor Series LAMBDA chains (page B-) for additional specifications on other lube-free chains. Pitch Bushing Width Pin Link Plate Average Approx.

Agriculture Chain Tsubaki offers both MR type and RF type steel roller chains for agricultural applications. MR type steel roller chains have been designed to replace malleable chains. These chains can be used with the existing sprockets for malleable chains. They have higher tensile strength, longer life, and provide smoother operation for drives and conveyors than malleable chains. Tsubaki MR type steel roller chains with various attachments can also be used for material handling operations. Tsubaki RF type steel roller chains have greater wear resistance and higher tensile strength than MR type steel roller chains. Pitch Roller Width Pin Link Plate Min. Approx.
