Outer sphere bearingUC320 UC322 UC324 UC326 UC328

External spherical bearings are preferred for applications that require simple equipment and components, such as agricultural machinery, transportation systems or construction machinery.

It is mainly used to bear radial and axial combined load based on radial load, generally not suitable to bear axial load alone, such bearings can be installed respectively inner ring (with a full set of rollers and retainers) and outer ring. This type of bearing does not allow the shaft to tilt relative to the housing, resulting in additional axial forces under radial load. The size of the axial clearance of the bearing has a great relationship with whether the bearing can work normally. When the axial clearance is too small, the temperature rise is higher. When the axial clearance is large, the bearing is easy to damage. Therefore, special attention should be paid to adjusting the axial clearance of the bearing during installation and operation, and pre-interference installation can be performed if necessary to increase the rigidity of the bearing.
