A high-precision slide bearing is provided which includes a substrate of sintered metal and a synthetic resin layer. This bearing can be used e.g. for rotary shafts in compressors of room air-conditioners or in transmissions of motor vehicles and construction machines to support relatively large radial and axial loads. The resin layer is integrally superposed on the radially inner surface of the sintered metal substrate of the slide bearing, which is a cylindrical member. The resin layer is made of a resin composition of an aromatic polyetherketone resin containing a fibrous filler. The fibrous filler are made up of fibers dispersed in the resin layer and oriented such that their length directions intersect the rotational direction of the bearing at angles of 45 to 90 degrees. The resin layer has a thickness of 0.1 to 0.7 mm.
A composite slide bearing comprising a substrate made of a sintered metal, and a resin layer fixedly superposed on the substrate, wherein the resin layer comprises a resin composition comprising an aromatic polyetherketone resin and a fibrous filler dispersed in the aromatic polyetherketone resin, wherein the fibrous filler comprises fibers which are oriented such that a length direction of each of the fibers intersects a rotational direction of the bearing at an angle of 45 to 90 degree, and wherein the resin layer has a thickness of 0.1 to 0.7 mm.
