The speed limit of angular contact ball bearings is higher,can bear both radial and axial loads,also be subjected to purely axial loads.Its axial load capacity is determined by the contact angle, and increases as the contact angle increases.
Single row angular contact ball bearings can only withstand axial load in one direction, and the radial load will cause additional axial force, must be applied to the appropriate reverse load, therefore the type of bearings are generally used in pairs. Double row angular contact ball bearings can withstand greater radial load as the principal of radial, axial joint bi-directional load and moment loads.It can limit axis or shell bidirectional displacements,which contact angle is 30 degrees.
Pairs of angular contact ball bearings can withstand the radial load,axial joint bi-directional load or under purely radial load. Tandem configuration can only take a single direction axial loads, other two configurations can accommodate axial loads in either direction.
This type of bearings are generally matching by manufacturers into the user, preloading of interference after installation, rings and balls are in axial preload condition, that improves stiffness and running accuracy of bearing the entire group as a single bearing.
