[Problem] To exchange the roller bearing that has been used in a scroll compressor mounted in an automobile with a m slide bearing. To provide a slide bearing having a performance that is at least equivalent to that of a roller bearing. [Solution] The slide bearing results from baking onto a back metal a sliding layer of 5-60 wt% graphite having an average diameter of 5-50 µm and a graphitization degree of at least 0.6, the remainder comprising a polyimide resin and/or a polyamide-imide resin. The form of the graphite has: (a) an average shape factor (YAVE) as defined of 1-4 for the particles excluding the minute particles that are no greater than 0.5 times the average diameter, and there being at least 70% by number of particles having a shape factor (Y) in the range of 1-1.5; or (b) graphite particles having a particle ratio of at least 0.5 being at least 50% of the total by number.

(Task) A PTFE-based sliding material, wherein the porous sintered layer on the surface of backing metal is impregnated with baked PTFE, and occasionally, with one or both of the solid lubricant and wear-resistant additive together with fibrous PTFE, is used for a bearing of air-conditioner. Resistance of the bearing for local wear is required. Such wear resistance is to be enhanced. (Solution Means) Carbides of oligomer or polymer 2 are incorporated in the entangled structure of fibrous PTFE 1.

Bearing 11 has base material 110 and coating layer 111. Base material 110 contains crank shaft 13 on an inner circumferential surface side. The inner circumferential surface of base material 110 is coated with coating layer 111. The inner circumferential surface side of base material 110 is coated with resin with thickness t, the resin is dried, and thereafter surface treatment is carried out such that multiple grooves C are provided on the surface of the resin so as to intersect with the direction of crank shaft 13, whereby coating layer 111 is formed. Peak portions B formed between adjacent grooves C come into contact with the outer circumferential surface of crank shaft 13 to support crank shaft 13. With bearing 11, the thickness of peak portions B at the center in the direction of the crank shaft 13 differs from the thickness of peak portions B at the end.
