Angular Contact Ball Bearing
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
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.
