Ultimate high speed angular contact ball bearings that can bear radial loads and axial loads, can also be subjected to purely axial load, the axial load carrying capacity determined by the contact angle and contact angle increases.
Single row angular contact ball bearings can accommodate axial loads in one direction, when subjected to radial load, will cause additional axial force must be applied to the corresponding back-loading and, therefore, this type of bearings are generally used in pairs.
Double row angular contact ball bearings can withstand greater radial load of radial, axial joint bi-directional loads and moment loads, it can limit the shaft or housing bidirectional axial displacement of the contact angle is 30 degrees.
Paired angular contact ball bearings can withstand radial load of radial, axial joint bi-directional load or under purely radial load. Tandem configuration can only take a single direction axial load, other configurations can bear axial loads in either direction.
This type of bearings are generally submitted by the manufacturers matching into the user after installation and preloading interference, rings and balls in axial preload condition, improving the whole group as a single bearing stiffness and running accuracy of the bearing.
