Insert bearing with housing

Outer spherical ball bearing is actually a variant of deep groove ball bearing, which is characterized in that the outer diameter surface of its outer ring is spherical and can be matched into the corresponding concave spherical surface of the bearing seat to play the role of centering. The outer spherical bearing is mainly used to bear the combined radial and axial load dominated by radial load. Generally, it is not suitable to bear the axial load alone.
Although its basic performance should be similar to that of deep groove ball bearing, because this kind of bearing is mostly used in rough machinery, the installation and positioning is not accurate enough, the axis alignment between shaft and seat hole is poor, or the shaft is long and the deflection is large, and the accuracy of the bearing itself is not high enough, and some structures are also rough, Therefore, the actual performance of the deep groove ball bearing with the same specification is quite discounted. For example, the outer spherical ball bearing with jacking wire is applied to the through shaft with poor stiffness and large deflection. The bearing has sealing rings on both sides, which can strictly prevent the invasion of dirt and has been filled when leaving the factory.
An appropriate amount of lubricant does not need to be cleaned or added before installation. When the jacking screw on the protruding end of the bearing inner ring is fastened on the shaft, the allowable axial load shall not exceed 20% of the rated dynamic load.
The performance of the outer spherical ball bearing with eccentric sleeve is basically the same as that of the outer spherical bearing with jacking wire, except that the jacking wire is not on the inner ring, but on the eccentric sleeve. The inner hole of the outer spherical ball bearing with conical hole is a conical hole with 1:12 taper, which can be directly installed on the conical shaft, or installed on the shoulder free optical shaft with the help of a tightening bushing, and the bearing clearance can be fine tuned.
Outer spherical bearings are preferred for occasions requiring simple equipment and parts, such as agricultural machinery, transportation system or construction machinery.
It is mainly used to bear the combined radial and axial load dominated by 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 retainer) and outer ring respectively. This kind of bearing does not allow the shaft to tilt relative to the housing, and additional axial force will be generated under the appointment of radial load. The axial clearance of this kind of bearing has a great relationship with 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, during installation and operation, special attention should be paid to adjusting the axial clearance of the bearing. If necessary, pre interference installation can be carried out to increase the rigidity of the bearing.
