In the organization operation, installation is allowed to the parts of the bearing FAG a certain temperature, when the hand over institutions shell, should not feel hot as normal, and indicates that taper roller bearings temperature was too high.

Bearing the temperature too high reasons: oil quality requirements or to deteriorate, high viscosity lubricating oil; Institutions tight assembly (gap deficiency); Tapered roller bearing assembly too tightly; The circle in the bearing shaft or shell and rotation; Overload; FAG or roller bearing maintains a fractured, etc.

The rolling bearing in the work to allow a slight operation noise, if too abnormal noise or noise or knocking, indicates that the bearing is a failure.

The cause of the rolling bearing produce noise is more complicated, one is bearing inner and outer surface with wear. Because of this wear, damaged and shell bearing, tapered roller bearing and the shaft with relations, lead to axis deviated from the correct position, in the shaft in high-speed motion produce different ring. When bearing fatigue, the metal surface spalling, also can make FAG bearing radial clearance increase abnormal sound produced. In addition, bearing insufficient lubrication, form of dry friction, and bearing, etc, will be broken cause abnormal sound. Tapered roller bearings wear loose after desert, maintains a looseness damage, also can produce different ring.
