Lubrication of the transmission chain is also very important

Chains (silent, roller or single-link chains) must be lubricated wherever they are used. The transmission chain requires lubricating oil to have good oiliness and penetrating ability. It can be firmly adsorbed on the inner and outer surfaces of the chain and can penetrate into all friction links of the chain links without being thrown off by the centrifugal force of the chain or squeezed out of the friction surface. For general low-speed chains, No. 30 mechanical oil can be used. Low-speed chains used in heavy equipment may also be treated with open gear oil or grease.
