Angular contact ball bearings are designed for combination radial and axial loading. Single-row bearings have high thrust capacity in one direction. These bearings have contact angles between the rings and balls. The standard angles are 15°.25°.and 40°.The greater the angle, the higher the axial load carrying capacity of the bearing. However, the smaller contact angle, the higher the rotating speed. Angular contact ball bearings are applied for high speed and high precision rotating condiations. These bearings are mainly applied in the machine tool spindles,high-frequency motors, gas turbines, oil pumps,air compressors, printing machines and other installations.....
