Miniature UC 201 Insert ball bearing, bore size 12 mm, 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. For example, the insert ball bearing with jackscrew is applied to the through shaft with large rigidity difference and deflection. Both sides of the bearing are provided with sealing rings, which can prevent the invasion of dirt and have been filled before leaving the factory.

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. Generally, it is not suitable to bear the axial load alone. This kind of bearing can be installed with inner ring (with full set of rollers and retainers) and outer ring respectively. This kind of bearing does not allow the shaft to tilt relative to the shell, and will generate additional axial force under the radial load. The axial clearance of this kind of bearing has a great influence on the normal operation of the bearing. When the axial clearance is too small, the temperature rise is high; when the axial clearance is large, the bearing is easy to be damaged. Therefore, special attention shall be paid to adjusting the axial clearance of the bearing during installation and operation, and pre interference installation can be conducted if necessary to increase the rigidity of the bearing.
