Four point contact ball bearing

The four point contact bearing is a single row angular contact ball bearing, so the space required in the axial direction is much smaller than that in the double row design.
The bearing consists of a solid outer ring, a split inner ring, and a ball and cage assembly with a brass or polyamide cage. The two-piece inner ring can accommodate a large number of balls. The inner race half matches the specific bearing and must not be interchanged with other bearings of the same size. The outer ring with ball and cage assembly can be installed separately from the two inner ring halves.
