    摘要： To provide an improved rolling bearing assembly having an improved resistance to electric corrosion, which can provide a proper performance and can be assembled at a reduced cost, the rolling bearing assembly includes an inner race (1), an outer race (2) and a circumferential of rolling elements (3) rollingly interposed between the inner and outer races (1) and (2). An electrically insulating layer (4) is formed on a surface of one of the inner and outer races (1) and (2), which is held in contact with a housing or a shaft when the rolling bearing assembly is mounted. This electrically insulating layer (4) is made of a gray alumina containing Al2O3 mixed with TiO2 in a quantity chosen to be equal to or smaller than 1 wt % relative to the total weight of the gray alumina.

    摘要： A pair of parts rotatable relative to each other about an axis are relatively supported by a roller bearing having a radially directed and angularly extending annular track unitarily formed on one of the parts and centered on the axis. The other of the parts is formed with a groove open toward the track and holding a track ring centered on the axis and formed with an annular track radially confronting the track of the one part and a cushion ring supporting the track ring in the groove on the other of the parts. An annular array of roller elements is provided between and engaging both of the tracks.

    摘要： A rolling bearing provided with measures to suppress a rise in temperature. The rolling bearing comprises inner and outer races, a plurality of rolling elements 16 interposed between the inner and outer races, and a cage for retaining the rolling elements 16. On the use conditions that the direction of load is stationary to the outer/inner race and rotational with respect to the inner/outer race of the two races, the cage 17 is guided for rotation with outer/inner regions of its pocket surfaces in contact with the rolling elements 16. It is also intended to facilitate satisfactory lubrication by means of grease and to enhance the durability and life of the bearing. For that purpose, a bearing 21 incorporated into a main motor is arranged with both end faces adjoining end members 24 and 25 that have grease pockets 22 and 23 formed therein, respectively. The bearing 21 includes an outer race 27 whose bore surfaces 33 and 34 on its ribs 31 and 32 are flush with the inner peripheries 35 and 36 of the grease pockets 22 and 23 in the end members 24 and 25, respectively.
