To provide a sliding member that improves seizure resistance by restraining any exposure of the porous layer and improves abrasion resistance and load resistance. The sliding member 1 constitutes a bearing having a cylindrical shape, an inner circumferential surface of which is a sliding layer 5 with an axis. In the sliding member 1, a porous layer 3 made of alloy material is formed on a surface of a metal base 2 and this porous layer 3 is covered by resin material 4 so that the sliding layer 5 is formed. In the sliding member 1, a particle size of metal powder 30 forming the porous layer 3 is within a range of 15 through 60 .mu.m, preferably, about 25 through 45 .mu.m. Further, in the sliding member 1, a thickness of the porous layer 3 is within a range of 0.06 through 0.1 mm and a thickness of the sliding layer 5 is within a range of 0.08 through 0.16 mm The thickness of the sliding layer 5 is set to be thicker on average than the thickness of the porous layer 3 so that the porous layer 3 is not exposed.

Sliding member and bearing

A sliding bearing having excellent initial conformability and seizure resistance as well as high durability and heat resistance is provided. A sliding bearing comprising a coating layer containing a resin and a solid lubricant formed on a bearing alloy layer, characterized in that the resin of said coating layer is a resin having a glass transition temperature of from 150.degree. C. to 250.degree. C. which has a great elongation at high temperatures.

Sliding bearing

Provided are that a cage for a rolling bearing in which seizure or break is not generated under a condition of a high temperature and a high speed in which a dmn value is not less than 80.times.10.sup.4, and a rolling bearing using the cage. The rolling bearing 1 is provided with an inner ring 2, an outer ring 3, a plurality of rolling elements 4 interposed between the inner ring and the outer ring and a cage 5 which retains the rolling elements 4. The cage 5 is formed by injection molding a resin composition. The resin composition comprises polyamide resin made from a dicarboxylic acid component and a diamine component as a base resin and a fiber reinforcing member added. The dicarboxylic acid component contains terephthalic acid as a main component. The diamine component contains 1,10-diaminodecane as a main component. The fiber reinforcing member contains 15 to 50 mass % of glass fibers or 10 to 35 mass % of carbon fibers based on the whole resin composition.
