Maintenance technicians should be aware of this and know the common causes of, and remedies for, bearing overheating. Electric Motors The ball bearings used in most electric motors are pregreased, shielded ball bearings. Normal motor bearing operating temperatures range from 140°F (60°C) to 160°F (71°C).

Units are lubricated via oil or grease and can be open, closed, radial or contact ball bearings. 1. Lack of Lubrication. Lack of lubrication causes the internal ball bearings to scrape against each other rather than glide. As these are metal, heat quickly builds leading to rapid failure of the bearing. 2.

Ball bearings are the most critical components of rotating machinery in oil and gas companies. Typical research has focused on bearing failure detection based on bearing failure frequencies derived from the velocity spectrum. However, most bearing failures are caused by improper or insufficient lubrication. The current research utilizes a case study demonstrating when ball bearings must be ...
