In fact, it is a variant of deep groove ball bearing. Its characteristic is that the outer diameter surface of its outer ring is spherical, which can be fitted into the corresponding concave spherical surface of the bearing seat to achieve alignment. Outer spherical bearings are mainly used to bear the combined radial and axial loads, which are mainly radial loads. Generally, they are not suitable to bear the axial load alone.

Outer spherical bearings are mainly used to bear the combined radial and axial loads, which are mainly radial loads. Generally, they are not suitable to bear the axial load alone. This kind of bearing can be installed with an inner ring (with a full set of rollers and retainers) and an outer ring respectively. lock up. This kind of bearing does not allow the shaft to tilt relative to the housing, and will generate additional axial force under any radial load. The size of 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 will be high; when the axial clearance is large, the bearing will be easily damaged. Therefore, special attention should be paid to adjusting the axial clearance of the bearing during installation and operation. If necessary, pre-interference installation can be performed to increase the rigidity of the bearing.
