(1) Lubrication (See P.132 ~ 134 and P.342.) Except for some chains of special materials or elements, most chain life can be prolonged with lubrication. A chain which requires lubrication will be shortened in life without lubrication. For example, chain elongation, corrosion and stiff joint occur due to wear of some chain parts. (2) Washing Washing If a chain is used with a material such as sand or metallic powder, the promotion of wear, stiff joint, etc. will be caused, shortening life. Wash away such harmful materials. For washing, dip the chain into kerosene, dry, and sufficiently lubricate....

Roller Chains for Power Transmission General Roller Chains for Power Transmission Dimensions and Performance of DID General Application Chains DID general application chains can be classified into two types in reference to strength; standard series chains complying with ANSI roller chains and HK series chains complying with ANSI, which have outer and inner plates thicker than those of standard chains. The standard series include two lines; standard roller chains, and HI-PWR-S chains improved in fatigue strength and shock resistance compared to the standard roller chains. You can use them as basic...

Pins support all the load acting on the chain, together with inner and outer plates, and when the chain is engaged with a sprocket, the pins slide as bearings. They are required to be high in shearing strength and bending strength, and especially wear resistance. Bushings act to prevent the shock received through rollers when the chain is engaged with a sprocket from being directly transmitted to pins, and also act as bearings, along with the pins. So, they are required to be high in shock fatigue strength and wear resistance. Rollers act to smoothly bend the chain when the chain is engaged with...
