<p>PROBLEM TO BE SOLVED: To provide a slide bearing which uses sintered metal as a base material and has a synthetic resin bearing layer, can provide precise and stable rotational torque, the slide bearing being high-precision and usable as a slide bearing capable of bearing a comparatively large radial load and an axial load such as, for example, rotary shafts of a compressor for a room air conditioner and a compressor for a car air conditioner and transmissions of an automobile and a construction machine.SOLUTION: There is provided the compound slide bearing in which a resin layer 2 is laminated on the internal diameter face side of a sintered metal-made base material 1 of a cylindrical slide bearing and formed integrally with the base material 1, the resin layer 2 is composed of a resin composition which is obtained by blending a fibrous filler into an aromatic polyether ketone resin, the fibrous filler 3 is dispersed into the resin layer in such a way that the longitudinal direction of a fiber is oriented so as to cross the rotation direction of the bearing at angles of 45° to 90°, and the resin layer 2 has a layer thickness of 0.1 to 0.7 mm. Wear damage to a mating member caused by edges of both ends of the fiber is reduced, and a friction coefficient is stabilized. This achieves the compound slide bearing which uses sintered metal as the base material and has the synthetic resin bearing layer 2, and can provide precise and stable rotational torque.</p> |
