Sliding bearing with polybenzimidazole

摘要

A sliding bearing includes a bearing alloy layer (3) having a sliding surface and a resin surface layer (4) formed on the sliding surface of the bearing alloy layer (3) and containing polybenzimidazole and a solid lubricant. In manufacturing the sliding bearing, a resin surface layer composition is applied to a roughened surface of the bearing alloy layer (3). The resin surface layer composition contains polybenzimidazole and a solid lubricant. The resin surface layer composition is heated so as to be hardened to be formed into the resin surface layer (4). A thermosetting bonding layer 11 may be provided. The solid lubricant can be MoS2, PTFE or graphite. The surface layer can have Si3N4 or Cu particle. The bonding layer can be PAI, PI, EP or a phenol resin. The bearing alloy layer can be of Cu or Al.
