There is. In this way, for example, if the bearing is operated for a considerable period of time under abnormal conditions without lubricating oil, and the surface layer is worn out as a result, the anodic oxide film will be exposed on the sliding surface. Become. As a result, the aluminum or aluminum alloy base material, which tends to cause agglomeration, is not exposed in the sliding motion, resulting in excellent seizure resistance.
