Spherical ball bearings is actually a variant of deep groove ball bearings, is characterized by its outer diameter surface of the sphere, it can be equipped into play within corresponding concave spherical bearing self-aligning effect.
Spherical ball bearings, although its basic properties and deep groove ball bearings should be similar, but because most of the bearings used in the rough mechanical, the installation location is not precise enough, the axis of the shaft and housing bore neutral difference, or long axis and large deflection under the circumstances, and bearing itself precision is not high enough, some structures are more rough, so the actual performance comparison of total performance of the same size deep groove ball bearings play on a considerable discount. For example with the top wire spherical ball bearings used large deflection stiffness difference through shaft, the bearings on both sides with a ring, to tight to prevent dirt intrusion, Pat factory filled with the right amount of lubricant before installation without cleaning, no additional lubrication agents, the top end of wire protruding screws on the bearing inner ring in the shaft when tightened. permissible axial load shall not exceed 20% of the dynamic load rating.
With eccentric outer spherical ball bearings and spherical bearing performance with the top wire of the same, but not on top of the inner wire, but in the eccentric sleeve bore tapered bore spherical ball bearing is with 1: 12 taper tapered bore, can be installed directly on the tapered shaft, or by means of adapter bushing mounted on the optical axis without shaft shoulder, and fine-tune the bearing clearance.
Spherical bearings priority for applications that require simple equipment and spare parts occasions, such as for agricultural machinery, transportation systems or construction machinery.
Mainly used to bear radial load mainly radial and axial load, generally should not alone bear the axial load, can install such a bearing inner ring (with the whole group of roller and cage) and the outer ring. The kind of bearing tilt axis relative to housing is not allowed, under the radial load appointments will produce additional axial force. This kind of bearing axial clearance of the size of the bearing can work in it when the axial clearance is too small , high temperature; axial clearance is large, bearing easily damaged so pay special attention to adjust the bearing axial clearance in the installation and operation, if necessary, and preloaded mounting to increase the bearing stiffness.
