Dry lubricating coating composition and sliding bearing using the dry lubricating coating composition as a sliding layer

摘要

PPROBLEM TO BE SOLVED: To provide a sliding bearing further improving bearing performance, particularly, non-seizure performance, initial compatibility and cavitation resistance. PSOLUTION: This sliding bearing has a sliding layer 2 on a surface of a bearing alloy layer 1 composed of a copper-based or aluminum-based alloy. The sliding layer 2 comprises a resin binder turned into a polymer alloy by adding high shearing by adding an epoxy resin and a coupling agent by using a polyamideimide resin as a main component, and a solid lubricant of 20 to 75 mass%, and thereby, toughness and strength are imparted to the sliding layer 2, and the non-seizure performance, the initial compatibility and the cavitation resistance can also be improved.
