Slip Ring Brushes (An electrical slip ring is a rotary continuity device to transfer electrical power, control, and data from a stationary to rotating member. Brushes ride on the slip ring as the rotor rotates.) The electrical connection to the rotor is made by connections to the brushes. We also make brushes with inserts for cleaning action to minimize the slip ring wear. Brush impregnations and treatments can also done to protect the slip ring surface from contaminated environments.
