Description: Angular contact ball bearing can withstand radial load and axial load simultaneously, as well as the pure axle loads. They have higher limit speed. High precision and high speed bearings usually take 15 degrees contact Angle. The contact angle decide the capacity of axial load. Retainers are made of brass, synthetic resins or others subject to individual bearing features and application conditions.
Single-row angular contact ball bearings can accommodate axial load in one direction, if enduring radial load, it will raise additional axial force. And only limited axial displacement of the shaft or housing in one direction. The contact angle of angular contact ball bearings is 40, so you can afford a large axial load. Design of angular contact ball bearing is non-separable, shoulder height on both sides of the inners and outer rings are different. In order to increase the bearing load capacity, lower one side of the shoulder, so that the bearing can be mounted into more balls.
Pairs of angular contact ball bearings can accommodate radial loads as the principal combined radial and axial bi-directional load or under purely radial load. Tandem configuration can only take a single direction axial load, other configurations can be subjected to either direction of axial loads. This type of bearings are generally submitted by manufacturers combine matching users, pre-loading interference after installation, rings and balls of steel in the axial pre-load state, thus improving the supporting stiffness and running accuracy of bearing the whole group as a single.
