Abstract
A bearing assembly retainer ring has pockets for holding cylindrical rollers in arcuately spaced relationship about a central axis of the retainer ring. Each pocket has two end faces that are spaced axially of the retainer ring and two side faces that are spaced laterally of the axial spacing between the two end faces. The pocket extends radially through inner and outer peripheral edges of the retainer ring to receive a roller therein having a diameter which is greater than the radial span of the pocket end faces so that the roller extends beyond the inner and outer peripheral edges of the retainer ring. The axial spacing between the pocket end faces is slightly greater than the axial length of the roller to provide restricted clearances between the ends of the roller and the end faces of the pocket when the roller is centered within the pocket. Chamfers are provided on the end faces of the pockets at the inner and outer peripheral edges thereof. These chamfers enable the roller to pivot within the pocket from a position wherein the roller is aligned axially between the pocket end faces to a cocked position wherein both end faces of the pocket contact the roller and/or the side faces of the pocket contact the roller to resist further pivotal movement.
