Three (four) points contact ball bearing is a single row angular contact ball bearing with one split inner ring or one split outer ring. It can carry axial load and can limit the axial displacement in both directions. It takes up less axial space than a double-row bearing. The split inner ring permits the incorporation of a large number of balls and, as a consequence the load carrying capacity is high. The bearing is separable, so that the inner ring and the outer ring with ball and cage assembly can be mounted individually.
