Bearings • Electric Motor Bearings

An electric motor bearings consists of an inner race, an outer race, bearing balls lubricated with oil, and a cage that evenly distributes the balls. During motor operation, the oil is compressed and moved by the rough ball bearing surfaces.Types of electric motor bearings include deep groove radial-, angular contact ball-, and cartridge-type bearings, and they are available with contact or non-contact seals or shields. The most common type is the AFBMA-7 C-3 rated bearing, which provides a 3- to 5-mil clearance in which lubrication flows in order to reduce friction.Leading manufacturers: SMB Bearings, VNC Bearing, Bearing Kinetics, EMB&B, Bartlett Bearing Company.
