It is analytic to import the importance that the antifriction bearing cooperates


28th February 2011 Bearing Technology 0 Comments
In order to make optimal operational performance from importing the bearing, the cooperation between inner circle and axle, outer lane and bearing seat hole must be correct. If cooperate with the surface to joint insufficiently, the bearing ring may do the circular motion on the axle or in importing the seat hole of bearing. This kind of phenomenon is called wriggling. Once cooperate with the surface to begin to wriggle, the bearing ring will begin to wear excessively, and can damage axle and pedestal, abrasive chip may enter the bearing, cause abnormal generating heat or vibration. It often ...
