A carbon brush is an electrical contact that conducts electrical current between the stationary and moving parts of a motor. Our premium carbon brushes are guaranteed to be equal in fit, form, and function. We stock thousands of Carbon Generators, Slip Rings, and AC Motor Brushes for a variety of popular applications. Our brushes can be custom designed and manufactured to meet the requirements of your specific motor or generator. Finding the proper brush design for the operating conditions of the motor is key to maximizing brush and contact life. Improper selection of brushes can cause rapid brush wear and damage to the contact surfaces.
