Angular Contact Ball Bearing
The angular contact ball bearing consists of the balls, inner ring, and outer ring that connect at an angle with a radial angle. The contact angle is divided into 15 degree, 30 degree and 40 degree.
Features and materials
The angular contact ball bearings mainly bear a larger one-way axial load; the greater contact angle has greater load capacity. Materials can be steel, brass, or engineering plastics
The angular contact ball bearings can bear both radial and axial load, and also can work at higher speed. 15-degree contact angle is usually used in high-precision and high-speed bearings. In the Axial force, the contact angle will increase.
-Depends on the bearing form or use of different conditions.
There are single row angular contact ball bearings, double row angular contact ball bearings and four-point contact ball bearings.
Single row angular contact ball bearings can only bear one direction of axial load. Also can only limit the axial displacement of the shaft or the housing in one direction.
