Abstract: There is provided a method of forming a coat on an inner surface of a bearing, in which a jig 13 is attached to a rotor 2 while holding four bearings 12 for example, so as to form those in a cylinder shape. Then, while the rotor 2 is rotated at a circumferential speed of 0.3 m/sec, a nozzle 8 for airless spraying is inserted into the rotor 2, so that the nozzle 8 injects a coating material 30 from the inside of the bearings 12 toward an inner surfaces of the bearings 12 to apply the coating material thereon. Because the coating material 30 is injected from the nozzle 8 without using compressed air, the fly amount of the coating material is made less as compared to air spray painting.

Abstract: An object of the present invention is to provide a sliding member which can slide for a longer period of time even in a dry state. In the present invention, sliding layers 3 are provided on the surfaces of a base material 2, and the sliding layer 3 contains polybenzimidazole (PBI) and 1 to 70 vol % of a solid lubricant. Since PBI, which is a thermoplastic resin, has higher heat resistance and also has higher material strength than PAI, PI, and EP, which are the conventionally used thermosetting resins, the wear resistance and the anti-seizure property can be improved and a decrease in material strength caused by high-temperature atmosphere, heat generation at the time of sliding, etc. can be restrained. Furthermore, the initial conformability can be improved because of high elongation percentage. Also, since the sliding layer contains the solid lubricant, the coefficient of friction can be decreased, and hence the anti-seizure property can be enhanced.
