The outer spherical ball bearing is actually a variant of deep groove ball bearing. The characteristic of bearing 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 adjust the center. Although its basic performance should be similar to that of deep groove ball bearings, due to the fact that this type of bearing is mostly used in relatively rough machinery, the installation and positioning are not precise enough, the axis alignment between the shaft and the seat hole is poor, or the shaft is long and has a large deflection, and the accuracy of the bearing itself is not high enough, some structures are also relatively rough, so the actual performance of deep groove ball bearings of the same specifications is significantly discounted.

The outer spherical ball bearing with top thread is used for shafts with large stiffness and deflection differences. This type of bearing has sealing rings on both sides to tightly prevent dirt from entering. It is filled with an appropriate amount of lubricant before leaving the factory and does not need to be cleaned or lubricated before installation. When the top thread screw on the protruding end of the bearing inner ring is fastened to the shaft, the allowable axial load shall not exceed 20% of the rated dynamic load.
The performance of the outer spherical ball bearing with eccentric sleeve is basically the same as that of the outer spherical ball bearing with top wire, except that the top wire is not on the inner ring, but on the eccentric sleeve. The inner hole of the conical bore outer spherical ball bearing is a conical bore with a 1:12 taper, which can be directly installed on the conical shaft or installed on the shoulder free optical axis with the help of a tightening sleeve, and the bearing clearance can be adjusted.
