angular-contactsteel

Characteristics and Uses of angular contact ball bearing: the limit speed or angular contact ball bearing is high, which can bear both radial load and axial load, which can also bear pure axial load, its axial load capacity is determined by the contact angle, and which will be increased with the increase of contact angle. Single row angular contact ball bearing can only bear one direction of the axial load, in the radial load, will cause additional axial force, the corresponding reverse load must be applied to , therefore, the bearing of this kind is generally used in pairs.Pairs of mounted angular contact ball bearings can bear radial and axial bidirectional joint load and mainly bear radial load, and also can bear pure radial load.The series configuration can only bear axial load in one direction, while the other two configurations can bear axial load in either direction.This type of bearing is generally selected and combined by the manufacturer in pairs and submitted to the user. With preload interference after installation, and the rings and steel balls are in the axial preload state, therefore improving the stiffness and rotation accuracy of the whole group of bearings as a single support.
