CHROME STEEL Pillow Ball Bearing
Product introduction
It is mainly used to bear radial and axial combined load based on
radial load, generally not suitable to bear axial load alone, such
bearings can be installed respectively inner ring (with a full set
of rollers and retainers) and outer ring. This type of bearing does not allow the shaft to tilt relative to
the housing, resulting in additional axial forces under radial
load. The size of the axial clearance of the bearing has a great
relationship with 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 damage. Therefore, special attention should be paid to adjusting the axial
clearance of the bearing during installation and operation, and
pre-interference installation can be performed if necessary to
increase the rigidity of the bearing
