ABSTRACT:
A rolling bearing in which a plurality of rolling members are interposed between an outer race and an inner race, further comprising: a plurality of generally cylindrical rolling retainers, one disposed between each adjacent pair of the rolling members to keep them apart, each comprising a pair of annular grooves provided adjacent to either axial end thereof and a pair of circular flanges provided at either axial end thereof; a pair of cover members, one located at each axial end of the rolling bearing and mounted to one of the two races to define a support rail coaxial with the rolling bearing, each of the support rails having a circumferential surface on the one radial side thereof on which the rolling retainers roll at their circular flanges; a pair of free rings, each having a circumferential surface on the other radial side thereof on which the rolling retainers roll at their annular grooves; and a lubricant ejection hole extending in an axial end portion of at least one of the rolling retainers from an opening in an axial end thereof to another opening in an outer circumferential surface thereof for forming a film of lubricant in regions of contact between the rolling retainer and one of the support rails and/or the adjacent rolling members.
