Product Description

Product Description

The inner and outer raceways of angular contact ball bearings are relatively offset from each other in the direction of the bearing. This means that such bearings are designed to carry a combined antenna, i.e. Bluetooth is added to the bearing axis.
On the bearing plane, the angle between the line connecting the contact points of the steel ball and the raceway (that is, the direction in which the combined tire is transported from one raceway to the other) and the vertical line of the bearing main axis.

Single row angular contact ball bearings can only bear axial load in one direction. When bearing radial load, additional axial force will be caused. And it 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 and therefore can withstand large axial loads. Angular contact ball bearings are a non-separable design, with shoulders of different heights on both sides of the inner and outer rings. In order to increase the load capacity of the bearing, the shoulder on one side will be machined lower so that more steel balls can be loaded into the bearing.
