Non-separable angular contact ball bearings are composed of inner and outer rings and rolling elements, and no part can be disassembled separately.

The ring groove of this type of bearing is locked, so the two rings cannot be separated.

There are three types of contact angles:

① Contact angle α=40°, suitable for bearing large axial load;

② Contact angle α=25°, mostly used for precision spindle bearings;

③ Contact angle α=15°, which is mostly used for larger size precision bearings.

Basic use:

◆ Machine tool spindle.

◆ High frequency motor.

◆ Gas turbine.

◆ Centrifugal separator.

◆ The front wheel of a small car.

◆ Differential pinion.
