The basic structure of Angular contact ball bearings is composed of inner ring, the outer ring, a group of ball, a Cage composition. At normal work state,contact angular is called a angular that line of the the contact point of the ball and inner ring or outer ring in the rayway form Included angle through vertical plane of axis line. The size of contact angle decide radial force and axis force at operation. The smaller the contact angle, the greater the load bearing axial.mainly for the radial load to bear, but it also can withstand axial load, high-speed operation and ultimate low noise devices.
Except the basic types of Angular contact ball bearings, there are separated type(four point contact ball bearing), Paired double-angular contact, Stamping Bowl angular contact, With Shield angular contact ball bearings ect.
