Bearing Wear And Fit Failure Of Mill

The thermal expansion of the inner ring will lead to the looseness of its fit with the journal, while the thermal expansion of the outer ring will lead to the tightening of its fit with the shell hole, which will lead to bearing heating.

The wear of ore milling plant bearing is the most important fault in the use of ore milling plant bearing. Continuous wear will change the size of inner ring, outer ring, rolling element and cage of ore milling plant bearing, and even produce pitting or peeling.

The matching clearance of ore milling plant bearing will increase and the surface roughness of running elements will increase, which will reduce the running accuracy of ore milling plant bearing and therefore the running accuracy of machine, Thus, the temperature, vibration and noise of the bearing will increase. In serious cases, it will lead to heating, vibration, bearing burning and even shaft bending.
