Three/Four Points Angular Contact Bearings-Ktaiballbearing

Three/Four Points Angular Contact Bearings are a type of single row angular contact ball bearing, they can support radial load and axial load in both directions.

The inner ring is split, and the bearings are separable, i.e. the inner ring halves and the outer ring with ball and cage assembly can be mounted individually.
