Paired angular contact ball bearings can bear radial

Paired angular contact ball bearings can Hydrodynamic Bearing radial load mainly radial and axial joint load can also be subject to pure radial loads. Tandem configuration can only bear axial load in one direction, the other two configurations can withstand axial load in either direction. This type of bearing is generally matching pairs by the manufacturer to submit a user after installation preload interference, rings and balls in the axial pre-load condition, thereby enhancing the entire group as a single bearing support stiffness and rotation accuracy.
