What is the performance of the spherical bearing insert?

Although the basic performance of the spherical bearing insert should be similar to that of the deep groove ball bearing, because this kind of spherical bearing insert is mostly used in relatively rough machinery, the installation and positioning are not accurate enough, the axis alignment between the shaft and the seat hole is poor, or the axis is long and the deflection is large, and the precision of the spherical bearing insert itself is not high enough, and some structures are also rough, Therefore, the actual performance of deep groove ball bearings of the same specification should be discounted. For example, the outer spherical ball bearing with jack screw is applied to the through shaft with large stiffness difference and deflection. The two sides of the bearing are equipped with sealing rings, which can tightly prevent dirt from invading. It has been filled when leaving the factory

An appropriate amount of lubricant is not required to be cleaned or supplemented before installation. When the jacking screw on the protruding end of the spherical bearing insert inner ring is fastened on the shaft, the allowable axial load shall not exceed 20% of the rated dynamic load.

The performance of the spherical bearing insert with eccentric sleeve is basically the same as that of the spherical bearing with jackscrew, except that the jackscrew is not on the inner ring, but on the eccentric sleeve. The inner hole of the spherical bearing insert is a tapered hole with a taper of 1:12, which can be directly installed on the tapered shaft or installed on the shoulderless optical shaft with the help of a set bushing, and the bearing clearance can be fine adjusted.

The spherical bearing insert is preferentially applicable to situations where simple equipment and parts are required, such as agricultural machinery, transportation system or construction machinery.

The spherical bearing insert is mainly used to bear the combined radial and axial load mainly consisting of radial load. Generally, it is not suitable to bear the axial load alone. This kind of bearing can be installed with inner ring (with full set of rollers and retainers) and outer ring respectively. This kind of bearing does not allow the shaft to tilt relative to the housing, and will generate additional axial force under the radial load. The size of the axial clearance of the bearing has a great influence on whether the bearing can work normally. When the axial clearance is too small, the temperature rise is high; When the axial clearance is large, the bearing is easy to be damaged. Therefore, pay special attention to adjusting the axial clearance of the bearing during installation and operation. If necessary, pre interference installation can be carried out to increase the rigidity of the bearing.
