The Use Of Vertical Roller Mill Bearing

In the use of vertical roller mill bearing with tight sleeve, due to improper maintenance methods, the bearing fit is too tight or loose while tight, which will also cause bearing heating and bearing wear. The bearing with a set sleeve is characterized in that the clearance of the bearing can be adjusted through the set sleeve, but improper adjustment will cause the rupture of the set sleeve or loose fit.

The tightening of the bearing with the tightening sleeve is generally judged by measuring the reduction of the radial clearance of the bearing, because after the interference fit is formed during tightening, the radial clearance of the bearing will be reduced on the basis of the original clearance, and the reserved radial clearance shall consider the influence of the temperature difference between the inner and outer rings when the bearing is working.
