Hi,
I have had a bearing failure on the NDE of a motor (fixed speed) - after the motor was extremely noisy and vibrating. The bearing was well lubricated, with the correct lubricant and the alignment checked. There were no signs of water ingress, corrosion or additional signs of failure mechanisms i.e. excessive temp.
The bearing has large ridges on the inside of the outer race that span half way round as seen in the photos. There are 5 screw pumps in the station - and this is the only one with repeated bearing failures. Any suggestions for the cause of failure?
Thanks in advance
