Abstract
A multi-layer sliding bearing having an excellent anti-fretting property, comprises a back steel layer, and a bearing alloy layer formed on the back steel layer. A film of phosphate having a thickness of 0.1-15 .mu.m is formed on a back surface of the back steel layer, thereby enhancing the anti-fretting property of the bearing. The provision of the phosphate film well compatible with a mating material overcomes damage to the bearing due to fretting in a high-speed range. Therefore, the bearing can fully exhibit a bearing performance even under severe conditions of use in a high-speed, high-temperature and high-load range as typically experienced in a high-performance engine.
