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 rolling bearing which is capable of preventing the rolling elements from dropping out from between the inner and the outer rings even when the separators have been worn to an advanced stage. A rolling bearing includes: a plurality of rolling elements arranged between an inner and an outer rings; and a plurality of prismatic separators disposed in a circumferential direction between the rolling elements. The separator includes integrally therewith a metal band on at least one of its outer surfaces including those which face the inner or the outer ring, or at least one of its axial side surfaces, excluding however, surfaces which face the circumferential direction and make contact with the rolling elements. The metal band has a narrower width than a width of the separator in the circumferential direction, and prevents wear of the separator from advancing beyond a certain extent.
