When the shaft rotation failure happens?


The following points may cause the shaft rotation failure:

First, the lubrication failure, oil level and bearing clearance.

Second, the influence of cleanliness, debris.

Third, friction in oil seal, shaft shoulder and seal, anti-loosening sheet (solar sheet).

Forth, the concentricity of the shaft is not right, and the axial jam caused by cross positioning.

Fifth, the bearing box has low accuracy and distortion.
