Angular contact ball bearings are: 7000C type (angle = 15 °)、  7000AC (angle = 25 °)  And 7000B (angle = 40 °).
The bearing cage can be made of copper, steel and nylon.

Angular contact ball bearings can bear both radial and axial loads. It can work at high speed. 

Single row angular contact ball bearings are mainly used for machine tool spindle, high frequency motor, gas turbine, centrifugal separator, small car front wheel, differential pinion shaft, booster pump, drilling platform, food machinery, dividing head, repair welding machine, low noise cooling tower, electromechanical equipment, coating equipment, machine tool slot plate, arc welding machine, etc.

Main applications of double row angular contact ball bearings: oil pump, air compressor, various transmissions, fuel injection pump, printing machinery, planetary reducer, extraction equipment, cycloid reducer, food packaging machinery, electric welding machine, electric soldering iron, inspection and analysis equipment, fine chemical machinery, etc.
