FAQ - What is a Self-lubriing Bearing? | GGB

Self-lubriing bearings work by having lubricant impregnated within the sliding layer of the bearing. This lubricant can either be liquid (oil) or solid (graphite, MoS2, lead) based on the requirements of the appliion (such as operating temperature). As the bearing operates, the lubricant is released through pores in the sliding layer
