Pillow Block UC BearingThe UC bearing is actually a variation
of the deep groove ball bearing. The characteristic is that the
outer diameter surface of its outer ring is a sphere, which can be
fitted into the corresponding concave sphere 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 with the radial
load as the main one, so it is generally not suitable to bear the
axial load alone.The bearings can be mounted with inner ring (with
full set of rollers and retainers) and outer ring respectively.This
type of bearing does not allow the shaft to be tilted relative to
the housing and will generate additional axial forces under radial
load.The size of the axial clearance of the bearing has a great
impact on the normal operation of the bearing. When the axial
clearance is too small, the temperature rise will be 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, it can be preloaded to increase the
rigidity of the bearing. Bearing Unit No.Shaft

and reliability of rolling bearings are greatly affected by the
materials which the bearing components are made from.BXY bearing
rings and balls are made of high quality of GCr15 vacuum-degassed
bearing steel.Chemical composition of GCr15 bearing steel is
basically equivalent to some representative bearing steel as the
