The invention contemplates a retainer ring for maintaining the angular spacing of rolling elements in an antifriction bearing, said ring being the product of a method and apparatus for precisely staked definition of element-retaining lugs prior to assembly of the rolling elements thereto. The ring material displaced by staking is limited by anvil formations which determine the precise spacing. Tolerances may be so closely set and held that rolling-element assembly to such a retainer ring involves only light radial pressure to transiently but not permanently deform the lug regions in a snap or detent action. The invention is described in application to roller-element retention and to ball-element retention, whether the retention is to be against radially inward loss (of rolling elements) or radially outward loss, or both.
