The code of Bearing insert UC203 with set screw is UC200 series (light series), UC300 series (heavy series) and UB (sb) 200 series. If the application environment is small, UC200 series is usually selected on the applications,, otherwise uc300 series is selected. Generally, there are two jackscrews on the spherical surface ball bearing, with an included angle of 120 °. The characteristic is that the jackscrew is used to Jack the shaft when cooperating with the shaft, and then it has a fixed effect. However, the cooperation environment needs to have a small oscillation scale. It is widely used in textile machinery, ceramic machinery and other manufacturing industries.

UC203 Bearing insert With eccentric sleeve, its code is: UEL200 series, UEL300 series, SA200 series. The main feature of this kind of ball bearing is that there is a certain eccentricity at the upper end of the bearing, and the eccentric sleeve with the same eccentricity cooperates with it. This kind of bearing can also be said to be a special bearing. Because it is mainly used in agricultural machinery (harvester, straw returning machine, thresher, etc.), this kind of spherical ball bearing is mainly used in the layout with strong beating, and the cooperation with the layout with bias can effectively reduce the strong jumping.
