What’s the features of uc bearings?

The uc bearings is actually a variant of the deep groove ball bearing. Its characteristic is that its outer ring outer diameter surface is a spherical surface, which can be fitted into the corresponding concave spherical surface of the bearing seat to play the role of alignment. The uc bearings is mainly used to bear the combined radial and axial load based on the radial load, and it is generally not suitable to bear the axial load alone.

Introduction of uc bearings
Although its basic performance should be similar to that of deep groove ball bearings, because this type of bearing is mostly used in rougher machinery, the installation and positioning are not accurate enough, the axis of the shaft and the seat hole are poorly aligned, or the shaft is long and deflection In the case of large-scale bearings, the accuracy of the 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 will be discounted. For example: the uc bearings with top wire is used in the through shaft with large rigidity difference and large deflection. This kind of bearing has sealing rings on both sides to prevent the intrusion of dirt. The appropriate amount of lubricant has been filled at the factory and does not need to be cleaned before installation. , No need to add lubricant, when the jack screw on the protruding end of the uc bearings inner ring is tightened on the shaft. The allowable axial load shall not exceed 20% of the rated dynamic load.

UC bearings refer to rolling bearings, which are a kind of precision mechanical components that change the sliding friction between the rotating shaft and the shaft seat into rolling friction, thereby reducing friction loss.

Due to the characteristics of the rolling bearing's own motion, the friction force is much smaller than that of the sliding bearing, which can reduce the power consumption in frictional resistance, so the energy saving effect is significant. From theoretical analysis and production practice, general small ball mills with rolling bearings as main bearings can save energy up to 30%~35%, medium-sized ball mills can save up to 15%~20%, and large-scale ball mills can save up to 10%~20%.
