Double Row Angular Contact Ball Bearing

Product Description

Angular contact ball bearings have high speed limits and are able to support both radial load and axial load. It can afford pure axial load, and its load capacity is decided by its contact angular, which will increase, when the contact angular is larger. Single row angular contact ball bearings could only afford the axial load in one direction, so we should use them in pairs. Two rows angular contact ball bearings could afford large two-way joint load and moment load, and it could limit the bi-directional axial displacement of the shell and shaft with a 30°contact angular. Angular contact ball bearings installed in pairs could withstand two-way co-axial load and pure radial load. . Series configuration can only afford a single direction axial load, and the other two configurations can withstand axial load in either direction. This type of bearings is generally submitted in pairs by the manufacturers to match combination of users, which will increase the entire group as single bearing support stiffness and rotation accuracy.
