Ball Bearings Ball bearings use a spherical rolling element (or a ball). They have an inner race and an outer race with a cage holding the rolling elements. The cage keeps the elements uniformly spaced. The inner and outer races have grooves in which the balls roll. Ball bearings support radial loads and a much lower thrust load.
