Angular contact ball bearings are a type of ball bearing whose contact angle determines its characteristics and application range. Contact angle refers to the angle between the connection between the steel ball and the raceway contact point and the radial plane of the bearing. Usually, the contact angle range of angular contact ball bearings is between 15 ° and 40 °.

Features of angular contact ball bearings:

It can withstand combined axial and radial loads.

High speed performance, suitable for high-speed operation.

Widely used angular contact ball bearings:

Machine tool spindle: It can provide high-precision rotation support to ensure the accuracy and surface quality of machining. In the spindle system of numerical control machine tools, angular contact ball bearings can effectively bear the axial and radial loads generated by cutting forces, ensuring high-precision and high-speed operation of the spindle.

The transmission of a car bears complex loads to ensure the stable transmission of power.

In aero-engines, angular contact ball bearings are also commonly used to support rotating components because they can operate reliably under harsh conditions of high temperatures, high speeds, and high loads.

In addition, angular contact ball bearings can also be combined in series, face-to-face or back-to-back to meet different load and accuracy requirements. For example, series combinations can withstand greater axial loads, while back-to-back combinations can withstand two-way axial loads.
