Persons installing, maintaining, and using the chain or sprocket should thoroughly familiarize themselves with the points outlined in this instruction manual to ensure no mistakes occur. Obey the following points in order to prevent hazardous situations. Do not use chains and accessories (accessories and parts) for anything other than their original purpose. Never perform additional processing on the chain. . Do not anneal the various parts of the chain. . Do not clean the chain with either acid or alkali, as they may cause cracking. . Do not electroplate the chain or its parts, as it may cause...

Roller Chain & Sprocket Maintenance 1.Before Use NOTE With the exception of endless chains, the transmission power tables in this catalog are based on use with connecting parts (connecting links or offset links). This drive chain catalog explains how to select, install and maintain all listed Tsubaki Roller Chains. Numerical figures are indicated in both SI and gravimetric units. Read through this catalog before use to ensure proper selection and usage. Also, carefully inform persons involved in installation and maintenance of all pertinent matters.

1. Basic Structure (Photo: RS Roller Chain) Outer link Width between inner link plates Roller diameter Inner plate Outer plate Connecting link plate Spring clip Offset link Connecting link Middle plate Inner link Basic Three Dimensions The pitch, roller diameter, and width between inner link plates are considered the basic three dimensions of a roller chain. When these dimensions are identical, a roller chain and sprocket are dimensionally compatible. *1Slip Fit When the shafts (pins and bushes) and holes are fitted together, there is a continuous loose fit. This is a fit where the range of tolerance...

Roller 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 of links in the roller chain, please use a design that requires an even number of links as much as possible. Please note that connecting links and offset links are normally coated with an anti-rust agent only. Always thoroughly lubricate pin and bush when assembling.

4.Handling 1. How to Cut Roller Chain If the chain you purchased is either a unit length (3,048 mm) or on a reel, it is necessary for you to cut the chain to the necessary length. How to cut a roller chain removed has not come loose or deformed. Do not use if loose or deformed. Safety precautions Using a chain vise and punch 1) Make sure to use a grinder when grinding the riveted portion of one end of the rivet-type pin. If it is extracted without being ground first, more time and effort will be spent, and will damage the chain. 2) Do not reuse any removed parts. Using a chain breaker 1. 1 Using...

Using RS-CS-B Chain Breakers 1) Ensure the tommy bar and grip are on the same side. Grip them so that they touch to spread the jaws. (See Fig. 8.) 2) With the side of the chain with the ground pins (or cotter pins) facing up, clamp the roller between the two jaws and support the roller chain. (See Fig. 9.) 3) Then, follow steps 2 – 4 for using RS-CS-A chain breakers. 1. 3 How to cut Poly Steel Chain 1) Support the outer 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...

(Fig. 14) With large roller chains, pull the ends of the roller chains with wire to prevent the chain from falling off. 2) Insert a connecting pin-sashi into the inner links on both ends. Insert two middle plates if using a multistrand chain, then insert the inner...
