A bearing particularly suitable for high-speed operation is provided and includes inner and outer races, a plurality of spherical elements disposed between the races and in rolling contact therewith, and a retainer disposed between the races and maintaining the elements in annularly spaced relation. The retainer is of molded one-piece construction and embodies first and second ringlike sections disposed in axially spaced concentric relation. The ringlike sections are interconnected by a plurality of annularly spaced struts. Corresponding segments of the ringlike sections, disposed between a pair of struts, have oppositely disposed, spherically contoured surfaces in contact with a spherical element positioned therebetween.
