Q: What is a UC bearing and why is it called so?

A： UC bearings are spherical bearing.

The outer spherical ball 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 spherical and can be fitted into the corresponding concave spherical surface of the bearing seat to play a self-aligning role. Although its basic performance should be similar to that of deep groove ball bearings, but because these bearings are mostly used in relatively rough machinery, the installation and positioning are not accurate enough, the axis of the shaft and the seat hole is poorly aligned, or the shaft is long and deflected. In the case of large grades, and the accuracy of the bearing itself is not high enough, and some structures are relatively rough, the actual performance of the performance is relatively discounted for deep groove ball bearings of the same specifications. Therefore, spherical bearings are generally used in places where the equipment and parts are relatively simple and less demanding, such as in agricultural machinery, transportation systems or construction machinery.
