Abstract: A ball-bearing retainer for suppressing gross oscillations of the retainer, balls, and raceways of high speed bearings. The retainer has a generally cylindrical shape and has a plurality of ball pockets. It is designed for insertion between two relatively rotating members which have confronting coaxial cylindrical surfaces. These surfaces may be formed integrally with the rotating members themselves or may be raceways placed between the rotating members for accommodating the balls held in the retainer. Formed upon a surface of the retainer and extending toward one or the other of the relatively rotating members is a plurality of lands or portions extending radially from the retainer. The lands are three in number symmetrically disposed about the inner or outer peripheral walls of the retainer. The centers of the lands are a nominal 120* apart and each land subtends an angle of 30* or less. Clearence between the surface of the lands and the confronting surface of one of the rotating members is typically of the order of tens of thousandths of an inch.
