Angular contact ball bearings have two types.

Double row angular contact ball bearing can bear radial and axial load joint load, limit shaft on both sides of the axial displacement.

Single row angular contact ball bearing only carry a direction of the axial load, when in bear radial load, can cause additional axial force must be applied to the corresponding reverse load, therefore, the bearings are generally used in pairs.


Angular contact ball bearings can be widely used in home appliances, machine tool spindles, high-frequency motors, gas turbines, small automobile front wheels, fitness equipment, medical devices, motorbikes, textile machines, autos and other areas.
