ABSTRACT:
There is provided a method of forming a coat on an inner surface of a bearing, in which a jig13is attached to a rotor2while holding four bearings12for example, so as to form those in a cylinder shape. Then, while the rotor2is rotated at a circumferential speed of 0.3 m/sec, a nozzle8for airless spraying is inserted into the rotor2, so that the nozzle8injects a coating material30from the inside of the bearings12toward an inner surfaces of the bearings12to apply the coating material thereon. Because the coating material30is injected from the nozzle8without using compressed air, the fly amount of the coating material is made less as compared to air spray painting.
