Angular contact ball bearings are with high speed limit, can support radial load and axial load ,can also be subject to pure axial load, the axial load capacity determined by the contact angle, with the contact angle increase,the capacity increases,too. 

Single row angular contact ball bearings only can withstand axial load in one direction, when burden the radial load, will cause additional axial force,and it must be applied to the corresponding reverse load, so the types of bearings are generally used in pairs.

Double row angular contact ball bearings can withstand greater radial load,mainly consisting of radial and axial combined load and torque load, it limits bi-axial displacement of shaft or housing.

Angular Contact Ball Bearing is mainly applied on high speed, high precision and little axial load occasions, such as airplane engine main shaft, machine tool main shaft and main shafts of other high speed precision machine. It can also be applied on high frequency motor, steam turbine, oil pump, air compressor and printing machine etc. It is one of the bearings most widely used in machinery industry.
