Introduction of outer spherical bearing series

The outer spherical ball bearing is actually a variant of the deep groove ball bearing, which is characterized in that the outer diameter outer surface of the outer ring ball is spherical, and can be fitted into the corresponding concave spherical surface of the bearing seat to serve as a centering function.

    Although its basic performance should be similar to that of deep groove ball bearings, most of these bearings are used in relatively rough machines, the mounting position is not accurate enough, the axis of the shaft and the seat hole is poorly centered, or the shaft length is deflected. In the case of a large class, and the accuracy of the bearing itself is not high enough, and some structures are also rough, so the actual performance of the common performance is relatively discounted compared to the deep groove ball bearing of the same specification. For example, the outer spherical ball bearing with top wire is applied to the through shaft with large difference in deflection. The bearing has sealing ring on both sides to prevent the intrusion of dirt. The factory is filled with a proper amount of lubricant, and it does not need to be cleaned before installation. No need to add lubricant, the top wire screw on the protruding end of the inner ring of the bearing is fastened on the shaft. The permissible axial load must not exceed 20% of the rated dynamic load.

    The outer spherical ball bearing with the eccentric sleeve has the same performance as the outer spherical bearing with the top wire, except that the top wire is not on the inner ring but on the eccentric sleeve. The inner hole of the tapered spherical outer spherical ball bearing is a tapered hole with a 1:12 taper. It can be mounted directly on the tapered shaft or mounted on the shaft without the shoulder by means of a tight bushing, and the bearing clearance can be fine-tuned.
