Four-point contact ball bearings

Four point contact ball bearings are radial single row angular contact ball bearings with raceways designed to support axial loads in both directions. For a given axial load, a limited radial load (load ratio) can also be supported. The bearing is separable, i.e. the outer ring with ball and cage assembly can be installed separately from the two inner ring halves.
