The outer spherical ball bearing is actually a variant of the deep groove ball bearing. Its characteristic is that its outer ring outer diameter surface is a spherical surface, which can be fitted 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 based on the radial load, and it is generally not suitable to bear the axial load alone.
It is mainly used to bear the combined radial and axial load, which is mainly the radial load. Generally, it is not suitable to bear the axial load alone. This type of bearing can be installed with an inner ring (with a full set of rollers and retainers) and an outer ring separately. This kind of bearing does not allow the shaft to be tilted relative to the housing, and additional axial force will be generated when the radial load is used. The size of the axial clearance of this kind of bearing has a great influence on whether the bearing can work normally. When the axial clearance is too small, the temperature rise is higher; when the axial clearance is large, the bearing is easy to be 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 used to increase the rigidity of the bearing.
