Outline of spherical bearing

The outer spherical ball bearing is actually a variant of the deep groove ball bearing, which is characterized by the spherical outer diameter surface of its outer ring, which can be fitted into the corresponding concave spherical surface of the bearing seat to play the role of self-aligning.

1、 Outer spherical ball bearing with top screw

Its code name is uc200 series (light series), uc300 series (heavy series), and deformation product UB (sb) 200 series. If the application environment is small, uc200 series is usually selected, otherwise uc300 series is selected.

Usually, there are two top screws on the outer spherical ball bearing, and the included angle is 120 °， Its feature is that when cooperating with the shaft, the top wire is used to push on the shaft, and then it has a fixed effect. However, the environmental demand of cooperation is necessary to be small. This kind of spherical ball bearing is widely used in textile machinery, ceramic machinery and other manufacturing professions.

2、 Tapered outer spherical ball bearing

The codes are uk200 series and uk300 series. The taper bore with inner diameter of 1:12 share of this kind of outer spherical ball bearing should be used in cooperation with the tightening sleeve. The characteristic of this kind of outer spherical ball bearing is that it can accept more load than the outer spherical ball bearing with top screw.

3、 Outer spherical ball bearing with eccentric sleeve

Its code name is: uel200 series, uel300 series, sa200 series. The main feature of this kind of spherical ball bearing is that the upper end of the bearing has a certain eccentricity, 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 jumping, and the cooperation of eccentric layout can effectively reduce the strong jumping.
