Abstract
In a sliding bearing in which a bearing metal layer is covered with a coating layer, the coating layer comprises a thermosetting resin as a base resin and soft metal particles dispersed in the base resin in an amount of 0.1 to 10% by volume based on the volume of the coating layer. The soft metal is harder than the base resin and has a higher thermal conductivity than the base resin, so that the wear resistance and anti-seizure property of the sliding bearing are improved. In particular, when the soft metal particles are of copper, silver, tin, zinc or the like, the soft metal particles react with the sulfur contained in a lubricating oil to form a thin metal sulfide film excellent in lubricity on the surface of the particles, whereby the coefficient of friction is made smaller.
