Angular contact ball bearing has a high limit speed, which can withstand both radial and axial loads, and can also withstand pure axial loads. Its axial load capacity is determined by the contact Angle, and increases with the increase of the contact Angle.

Single row angular contact ball bearings can only bear one direction of axial load, when bearing radial load, will cause additional axial force, must be applied to the corresponding reverse load, therefore, the bearing is generally used in pairs. Double row angular contact ball bearing can bear large radial load, axial bidirectional combined load and torque load, which is mainly radial load. It can limit the axial displacement of the shaft or shell, and the contact Angle is 30 degrees.

Angular contact ball bearings mounted in pairs can withstand radial and axial bidirectional combined loads, mainly radial loads, and can also withstand pure radial loads. The series configuration can only withstand axial loads in one direction, while the other two configurations can withstand axial loads in either direction. This type of bearing is generally selected and combined by the manufacturer and submitted to the user in pairs. After installation, the ring and the steel ball are in the state of axial preloading, thus improving the stiffness and rotation accuracy of the whole set of bearings as a single support.
