Linqing XINRI Precision bearing CO.,LTD.

The outer spherical ball bearing is actually a variant of the deep groove ball bearing. Its characteristic is that its outer ring outer diameter surface is spherical, which can be fitted into the corresponding concave spherical surface of the bearing seat to play the role of centering. 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 comparable 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, which can strictly prevent the intrusion of dirt. The factory is loaded 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.
