main reason of increasing vibration in ball mill pinion

Prosig Noise & Vibration Blog

The ball bearings used in most electric motors are pre-greased, shielded ball bearings. Normal motor bearing operating temperatures range from 140 to 160 F. As in all bearing applications, this measurement should be taken at the bearing outer ring.
