Types of Bearing Damage and Failures in Motors

Bearings are an essential component of electric motors. They provide shaft support, facilitate even load handling, reduce friction between the shaft and stationary parts of the motor, and increase the longevity and reliability of rotating assets. Many types of bearings are used in electric motors including sleeve bearings, sealed bearings, shielded bearings, and many other varieties.

No matter which type of bearing is used, several types of damage can occur if they are not properly installed, operated, and maintained. This eBook will explain what types of bearings electric motors use, the functions they perform, and the types of bearing damage and failure commonly seen in electric motors and generators.
