Lubrication

Proper lubrication of roller chain is essential for peak performance and full chain life. In particular, the greater the level of performance demanded of the chain, the more the need for lubrication increases.

  • (1)The purpose of lubrication is to reduce wear on chainparts, prevent corrosion (rust), and economize on powerdemands.
  • (2)Lubricate the chain periodically (about once a week) so that the chain always remains damp with oil. Drip lubricate (using lube listed below) or apply lube with a brush.
  • (3)Lubrication locations
    Since wear between pins and bushes causes chain elongation, lubrication must be maintained on all contact surfaces. Also, areas where chain parts (plates, etc.) come into contact with guide rails must be lubricated (see Figure 26).
