302 flat collar bearing khurmi
Collar bearings are also called as Thrust bearings
UNIFORM WEAR
the rate of wear depends upon the intensity of pressure (p) and
the velocity of rubbing surfaces (v). It is assumed that the rate of wear is proportional to the product
of intensity of pressure and the velocity of rubbing surfaces (i.e. p.v..). Since the velocity of rubbing
surfaces increases with the distance (i.e. radius r) from the axis of the bearing, therefore for uniform
wear
