Single row angular contact ball bearings can support very high radial forces and axial forces in one direction. They are fitted and delivered as a bearing pair in an O or X arrangement. In order to ensure safe function of the bearing supports it is important to correctly adjust the bearings to facilitate thermal expansion of the shaft during operation.
Single row angular contact ball bearings are available in sealed and unsealed versions. Suitable materials for the cage are steel, brass or plastic depending on the application. Angular contact ball bearings are used particularly if a very high freedom from clearance is required, for example, on simple spindles. Angular contact ball bearings are commonly fitted in large motors with a vertical shaft position.
