Abstract
A sliding bearing includes a bearing alloy layer having a sliding surface and a resin surface layer formed on the sliding surface of the bearing alloy layer and containing polybenzimidazole and a solid lubricant. In manufacturing the sliding bearing, a resin surface layer composition is applied to a roughened surface of a bearing alloy layer. 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 a resin surface layer.
Claims9
A sliding bearing comprising:
- a bearing alloy layer having a sliding surface;
- a bonding layer comprising a thermosetting resin and further comprising one or more of polyamide-imide, epoxy resin and phenol resin, and provided on the sliding surface of the bearing alloy layer;
- and
- a resin surface layer provided on the bonding layer and containing 20 to 95% by volume of polybenzimidazole as a base resin, and 5 to 80% by volume of a solid lubricant, the bonding layer being provided for improving a bonding strength between the bearing alloy layer and the resin surface layer.
