ABSTRACT:
A ball-bearing retainer in which rigid members support a soft, flexible, highly porous annular body having ball pockets for receiving bearing balls. The annular body is made of a porous foamlike material capable of absorbing between 40 and 80% by volume of a liquid lubricant such as oil, and being capable of supplying 60 to 80% of the stored lubricant to the bearing. Because of its flexibility, the annular body may be of one-piece construction with spherical ball pockets, and may be closely fitted to the bearing races and balls.
