The Insert ball bearing 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 centering. The outer spherical bearing 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.

Although its basic performance should be similar to that of deep groove ball bearings, because most of these bearings are 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 and deflection In the case of large-scale bearings, the accuracy of the bearing its 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 insert ball bearing with top wire is used in the through shaft with large rigidity difference and large deflection.

This kind of bearing has seal rings on both sides to prevent the intrusion of dirt. The appropriate amount of has been filled at the factory and does not need to be cleaned before installation. , No need to add , when the screw on the protruding end of the bearing inner ring is tightened on the shaft. The allowable axial load shall not exceed 20% of the rated dynamic load.

The performance of the insert ball bearing with eccentric sleeve and the outer spherical bearing with top thread is basically the same, except that the top thread is not on the inner ring, but on the eccentric sleeve. The inner hole of the tapered outer spherical ball bearing is a tapered hole with a taper of 1:12, which can be directly installed on a tapered shaft or on a shoulderle optical shaft with the of a tightening bushing, and the bearing clearance can be fine-tuned.The insert ball bearings are preferentially suitable for ocns that require simple equipment and parts, such as agritural machinery, nsportation syst or construction machinery.

It is mainly used to bear the combined radial and axial load based on the radial load. Generally, it is not suitable to bear the axial load alone. This type of bearing can be installed with an inner ring (with a full set of rollers and retainers) and an outer ring. This kind of bearing does not allow the shaft to be inclined relative to the housing, and additional axial force will be generated under the radial load. The size of the axial clearance of this kind of bearing is very ant to the normal operation of the bearing. When the axial clearance is too small, the temperature rise is higher; when the axial clearance is large, the bearing is easy to be damaged. Therefore, special attention should be p to adjusting the axial clearance of the bearing during installation and operation. If neceary, pre-interference installation can be used to increase the rigidity of the bearing.
