A stable cage for the balls of a ball bearing in which the annular body of the cage having radially extending cylindrical ball pockets therein is provided with spaced annular grooves in its inner or outer surface which grooves run through the pockets at locations along which the bearing balls normally would contact the edge of the pocket cage. The construction simulates square ball pockets thus to reduce the tendency of the cage to vibrate and to operate in an unstable mode.
