摘要:
An inventive ball bearing retainer (4) is entirely composed of a resin composition, and has pocket surfaces (6) for retaining balls (5) and projections (8) provided on the pocket surfaces (6) and containing a solid lubricant (CB). A ball bearing (1) incorporates the ball bearing retainer (4). By the effect of the solid lubricant (CB), the projections (8) are less liable to be worn out in a short period particularly when the ball bearing (1) is used in a higher temperature environment. The projections (8) define clearances between the balls (5) and the pocket surfaces (6), making it possible to maintain the effect of preventing noise, increase in the torque of the ball bearing (1), reduction of the service life of a lubricant and the like for a longer period of time.
