Imports of spherical ball bearings is actually a variant of deep groove ball bearings, is characterized by a spherical surface of the outer ring outside diameter, can be equipped with the imported bearing concave spherical play a role in the self-aligning.

    Although its basic properties and deep groove ball bearings should be similar, but due to this bearing is mostly applied in the relatively coarse mechanical installed orientation is not precise enough, the axis of the shaft and housing bore of the neutral differential, or shaft length and deflection the big case, and bearing its own accuracy is not high enough, some structures are more rough, so a considerable discount on the total performance of the actual performance of the same specifications as deep groove ball bearings fight. For example, with the top wire of the outer spherical ball bearings used in stiffness differential deflection through shaft bearings on both sides with seals tight to prevent dirt intrusion, Pat filling the right amount of lubricant in the factory, and need not be washed before installation without additional lubricant, bearing inner ring on the protruding end of the top wire screw shaft fastening. Allowable axial load shall not exceed *0% of the rated dynamic load.

    With eccentric sleeve insert ball bearings and spherical bearings performance with the top wire is basically the same, just the top wire, not on the inner ring, but in the eccentric sleeve. Bore tapered bore spherical ball bearings with 1:*2 taper tapered bore can be directly installed on the cone axis, or through a tight set of bushings installed without shaft shoulder on the optical axis, and can fine-tune the bearing clearance.
