Product Description

Angular contact ball bearing has a high limit speed, can bear radial load and axial load at the same time, and can also bear pure axial load. Its axial load capacity is determined by the contact angle. The higher the bearing capacity, the smaller the contact angle and the smaller the axial load.

Conversely, the smaller the contact angle, the greater the ability to withstand radial loads, and the more suitable for high-speed applications. Single row angular contact ball bearings can only bear axial load in one direction.

Angular Contact Ball Bearings

When bearing radial load, it will cause additional axial force and can only limit the axial displacement of the shaft or housing in one direction. Angular contact ball bearings have a contact angle of 40 degrees, so they can withstand large axial loads.

Angular contact ball bearings are of non-separable design, with shoulders at different heights on both sides of the inner and outer rings. To increase the load capacity of the bearing, one of the shoulders is machined lower, allowing the bearing to fit more balls.
