摘要：
The grease-sealed bearing is formed on rolling surfaces (4) of rings (2, 2) of the bearing (1) with oxide layers (5) having a thickness of 0.1-2.5 microns, the development of peculiar peeling on the rolling surfaces of the bearing can be prevented. If it is used as a bearing for an alternator or the like, its duration can be increased.
