    摘要: The raceway surfaces of the inner and outer rings 1 and 2 and the surfaces of the rolling elements 3 are formed with lubricating films 1a, 2a and 3a of polytetrafluoroethylene having average molecular weight of not more than 5000 {PTFE (A)}. PTFE heretofore used for rolling bearings is a polymer having average molecular weight of more than 1.times.10.sup.5 mostly 1.times.10.sup.6 -1.times.10.sup.7, but PTFE(A) is very low in shear strength and soft as compared with PTFE polymer.

    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.
