If the chain that need lubrication has been kept long time unlubricated, the life of chain is shorter than Due to the difference of operating enviroment, expected. condition, teeth of sprocket, status of lubricating and so on, the life span of chains is different even if the chains are the same type and same size. If new chain is used with old sprocket with worn teeth, or if new sprocket is used with old chain that has already been elongated, the life of chain and sprocket gets shorter. 4 ROLLER CHAIN N AI H C R E ROLLER CHAIN DIMENSIONS H LL O R UNIT Upper:inch ANSI standard roller chain Beneath:mm Average Max.

Both sides of the hole are parallel, better increase fatigue strength. A FE bearing between pins and holes. This process increases fatigue strength. 3. Oil Port oriented + Solid Bush These holes, located on the inner side of the bushings away from bearing area, function as a reservoir for extra lubricant. This feature reduces chain wear and extend the chain’s operating life. Oil port Oriented 4. Cylindrical roundness of Solid Bush The advantage of solid bush, cylindrical roundness, making a large bearing area and oil port as an oil reservoir, improves the chain wear resistance and minimize an initial chain elongation. 5. Preloading OCM roller chain is preloaded automatically after assembly to minimize initial elongation. 6 FEATURES OF OCM ROLLER CHAIN N AI H C R E ROLLER CHAIN L L O R M C O F CONSTRUCTION OF ROLLER CHAIN O S E Roller chain is made up of roller links and pin links. UR T Roller link consists of two bushings press-fitted into roller link plates with two free rotating rollers over the A E F bushings. Pin link consists of two pin link plates into which two pins are press-fitted. There are two types of pins. Rivet and cotter types.
