Hardware Knowledge Base: "Spherical Bearings"

Spherical spherical ball bearings are actually a variant of deep groove ball bearings. Its special feature is that its outer ring outer diameter surface is spherical and can be fitted into the corresponding concave spherical surface of the bearing block to play a role in aligning.

Although its basic performance and deep groove ball bearings should be similar, but because of this type of bearing are mostly used in relatively rough machinery, the installation position is not accurate enough, the axis of the shaft and the center of the seat hole is poor, or the shaft length and deflection In the case of large size, the accuracy of the bearing itself is not high enough, and some structures are relatively rough. Therefore, the performance of the actual performance of a deep groove ball bearing of the same specification is markedly discounted. For example, the outer spherical ball bearing with top wire is applied to the through-shaft with large difference in rigidity and deflection. This type of bearing has seals on both sides, which can prevent the intrusion of dirt strictly. When it leaves the factory, it is filled with an appropriate amount of lubricant. No cleaning is required before installation. No additional lubricant is required. When the top screw on the protruding end of the bearing inner ring is tightened on the shaft, the allowable axial load must not exceed 20% of the rated dynamic load.

The outer spherical ball bearing with eccentric sleeve has the same performance as the outer spherical bearing with top thread, but the top thread is not on the inner ring but on the eccentric sleeve. The inner bore of the tapered bore outer spherical ball bearing is a tapered bore with a 1:12 taper, which can be mounted directly on the tapered shaft or by means of a tight bushing mounted on the shaft shaft without shoulders, and can fine-tune the bearing clearance.

Outer spherical bearings are preferred for applications where equipment and components are required to be simple, such as on agricultural machinery, transportation systems or construction machinery.

Mainly used to bear the radial and axial combined load mainly radial load, generally not alone to withstand axial load, this type of bearing can be installed inside the ring (with a full set of rollers and retainers) and the outer ring. This type of bearing does not allow the shaft to tilt with respect to the housing and will generate additional axial forces when under radial load. The size of the axial clearance of the bearing has a great relationship with the normal operation of the bearing. When the axial clearance is too small, the temperature rise is high; when the axial clearance is large, the bearing is easily damaged. Therefore, during installation and operation, special attention should be paid to adjusting the axial clearance of the bearing, and if necessary, it can be installed in advance to increase the rigidity of the bearing.
