China UC203-11 Insert ball bearing

The insert ball bearing is a variant of the deep groove ball bearing. the outer diameter surface of the outer ring is spherical, which can be fitted into the corresponding concave spherical surface of the bearing housing to play the role of centering. The insert ball bearing is mainly used to bear the combined radial and axial load, which is mainly the radial load. Generally, it is not suitable to bear the axial load alone

Although its basic performance is similar to that of deep groove ball bearing, most of the bearings are used in relatively rough machinery, the installation and positioning are not accurate enough, the axis of the shaft and the seat hole is neutral, or the shaft is long and the deflection is large, and the accuracy of the bearing itself is not high enough, and some structures are relatively rough, so the actual performance of the bearing is relatively the same specification Deep groove ball bearings are subject to considerable discount.

The code of Insert ball bearing 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 °.

Insert ball bearings are preferred for applications requiring simple equipment and components, such as agricultural machinery, transportation systems, or construction machinery.

It is mainly used to bear the combined radial and axial load mainly based on the radial load.

Insert ball bearing 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.

Proper amount of lubricant is not required to be cleaned before installation, and lubricant is not required to be added. When the jacking screw on the protruding end of the bearing inner ring is fastened on the shaft, the allowable axial load shall not exceed 20% of the rated dynamic load.
