Types of motor bearings Bearing-related failures account for 51% of all motor failures. The more you know about the types of motor bearings, their failure modes, and how to maintain them, the better prepared you will be to take steps to help extend the life of motor bearings.     Rolling Bearings Rolling bearings, also known as friction-reducing bearings, are an indispensable component of most electric motors. They allow shafts and axles to rotate at incredible speeds with minimal power loss, and they do so by greatly reducing friction by replacing sliding motion with rolling motion. Rolling bearings are usually classified by the type of element used, the most common being ball bearings and cylindrical bearings. Ball Bearings In a ball bearing, rolling motion is provided by balls that are held in place by raceways and cages. Ball bearings support high speeds and very low friction, and they can handle light to medium loads. Motor ball bearings are typically used in direct-coupled applic
