Angular contact ball bearings has contact Angle, which can bear both radial load and unidirectional large axial load. In addition, it is generally used to combine several bearings, such as two, three, four and so on
Single row angular contact ball bearings have contact angles and are therefore suitable for bearings axial or composite loads in one direction .In structure, axial separation occurs after bearings radial load. Therefore, two bearings are used in pairs, or more than two bearings are used in a pair. Single-row angular contact ball bearings, which can be preloaded to improve rigidity, are therefore suitable for high-precision machine tool spindles, etc.In general, angular contact Angle bearings retainers with contact angles of 30 degrees (code A) and 40 degrees (code B), according to table 1.However, synthetic resin cage or polyamide cage are also used according to different conditions
Single row angular contact ball bearings back-to-back double, inner ring, outer ring into a single structure .It can bear axial load in two directions and has torque load capacity. It can be used as fixed end bearings. Use a press cage
Point contact ball inner ring is divided into two, with a bearing can bear two directions of axial load. Contact Angle of 35 degrees axial load capacity, suitable for the pure axial load, or large axial load composite load .The cage is made of copper alloy
