Four-point contact ball bearings are radial single row angular contact ball bearings with raceways that are designed to support two-directional axial loading. Four-point contact ball bearing requires a minimum amount of space and can carry either pure axial loading or combined loading. Four-point contact ball bearing can be separated, i.e. the outer ring with ball and cage assembly can be mounted separately from the two inner ring halves. The split inner ring leads to easier mounting and dismounting of the bearing. A large number of balls are incorporated, giving the bearing its high load carrying capacity.
