Although its basic performance and deep groove ball bearings should be similar, but because most of the bearings used in rough machinery, installation and positioning is not accurate enough, the axial axis of the hole with the seat of the neutral difference, or axial length and deflection Large and so on, and the accuracy of the bearing itself is not high enough, some structures are relatively rough, so the performance of the actual performance of the same specifications of the deep groove ball bearings to play a considerable discount. For example: with the top wire of the spherical ball bearings used in poor rigidity of the large deflection through the shaft, this bearing on both sides with a seal, to prevent dirt intrusion, the factory has been filled
The amount of lubricant, no cleaning before installation, without additional lubricant, bearing inner ring protruding top of the top wire screw fastening in the shaft. The permissible axial load shall not exceed 20% of the rated dynamic load.
With the eccentric sleeve of the spherical ball bearing with the top wire of the spherical bearing performance is basically the same, but the top wire is not on the inner ring, but in the eccentric sleeve. Tapered bore ball bearings with a 1:12 taper hole, can be directly installed in the cone-shaped shaft, or through the adapter sleeve installed in the absence of shoulder optical axis, and can fine-tune the bearing clearance.
Spherical spherical bearings are preferred for applications requiring simple equipment and components, such as for agricultural machinery, transport systems or construction machinery.
Mainly used to bear the radial load mainly radial and axial load, generally should not alone bear axial load, such bearings can be installed inner ring (with the whole group of rollers and retainer) and the outer ring. This type of bearing does not allow the shaft to be tilted with respect to the housing, resulting in additional axial forces under radial load. The kind of bearing axial clearance of the size of the bearing can work properly, when the axial clearance is too small, the higher the temperature rise; axial clearance is large, the bearing is easy to damage. Therefore, in the installation and operation to pay special attention to adjust the axial bearing clearance, if necessary, pre-installed surplus to increase the rigidity of the bearing.
