Influence of angular contact ball bearing check
Apr 22, 2016

Shaft for machine tools, especially the main shaft, generally with thrust ball bearings are assembled into a whole, and rotating at very high speeds, sometimes very high heat is generated. This phenomenon, if not excluded, will result in angular contact ball bearings to overheat and the corresponding parts of machine tools thermal deformation of boundary lubricating bearing temperature rise, severely high range when the spindle and tailstock, which not only affects the precision and accuracy of the machine itself and the bearing burned out.

Rating fatigue life, refers to a set of bearings of the same type, under the same conditions of operation, 90% du composite sleeve not appear angular contact ball bearing rolling fatigue spalling caused by the total number of go. Speed constant, represented by total running time rating fatigue life.
