Angular Contact Ball Bearing


The single row angular contact bearings can support the axial load in one specific direction. Its axial loading capacity depends on the contact angle

The single row angular contact bearings can support  the axial load in one specific direction. Its axial loading capacity depends on the contact angle α. The bigger the contact angle is, the higher its axial bearing capacity is. The typical contact angle is 15°, 25°, and 40°.

 This kind of bearing is divided in two types: separable and inseparable types.

 Metal solid cages are mainly used in single row angular contact ball bearings. Phenolic cloth laminated tube solid cages are usually used for high speed applications, and the maxinum temperature is 120°C.
