摘要: The raceway surfaces of inner ring 1 and outer rings 2 and the surfaces of rolling elements are respectively formed with solid lubricating films 1a, 2a and 3a of PTFE whose average molecular weight is not more than 5,000.These solid lubricating films each have a continuous island distribution comprising island film portions 5 and connective film portions 6 interconnecting the island film portions 5.

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.
