摘要： Disclosed is a sliding bearing in which a heat emission property of the sliding bearing is improved without affecting the original function of an overlay layer. An overlay layer is formed on a higher load-side bearing half, and extends circumferentially from a central portion thereof toward each of opposite ends thereof. Any overlay layer is not formed on a lower load-side bearing half, so that a bearing alloy remains exposed to the surface of this bearing half.

摘要： A multilayer sliding member is provided that contains no lead but has superior friction and abrasion properties under the conditions of high PV values and can be used suitably in dry lubrication environments. The multilayer sliding member includes: a porous metal layer that is formed on a back metal; and a sliding layer that is formed by impregnating and coating the porous metal layer, wherein the sliding layer includes 1 to 25% by volume of an oxybenzoyl polyester resin, 1 to 15% by volume of a phosphate, 1 to 20% by volume of barium sulfate, and polytetrafluoroethylene resin. The oxybenzoyl polyester resin (POB) improves the strength and abrasion resistance of the sliding material, and the synergistic effect of the phosphate and barium sulfate facilitates the transfer of PTFE to a counter material during sliding, so that the coefficient of friction can be decreased and the abrasion resistance can be improved.

摘要： 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.
