What are the characteristics of uc bearings?

UC bearing refers to the outer spherical bearing.

The UC bearing is actually a variant of the deep groove ball bearing, which is characterized in that the outer diameter surface of the outer ring is a spherical surface, which can be fitted into the corresponding concave spherical surface of the bearing seat to play the role of centering. Although its basic performance should be similar to that of deep groove ball bearings, because these bearings are mostly used in relatively rough machinery, the installation and positioning are not accurate enough, the axis alignment between the shaft and the seat hole is poor, or the shaft is long and the deflection is large.

In other cases, and the accuracy of the UC bearing itself is not high enough, and some structures are relatively rough, so the actual performance of the deep groove ball bearing of the same specification should be marked with a considerable discount. Therefore, UC bearings are generally used in applications where equipment and components are relatively simple and less demanding, such as agricultural machinery, transportation systems or construction machinery.

UC bearings are mainly used to bear combined radial and axial loads mainly based on radial loads. Generally, it is not suitable to bear axial loads alone. Such UC bearings can be installed with inner rings (with a full set of rollers and cages) and outer rings. lock up. This kind of bearing does not allow the shaft to be inclined relative to the housing, and additional axial force will be generated under the radial load. The size of the axial clearance of this kind of UC bearing has a great relationship with whether the bearing can work normally. When the axial clearance is too small, the temperature rise is high; when the axial clearance is large, the bearing is easily damaged. Therefore, special attention should be paid to adjusting the axial clearance of the bearing during installation and operation. If necessary, pre-interference installation can be performed to increase the rigidity of the bearing.
