Description

Single-leg carbon brush holder is a lightweight, space-saving single foot brush holder assembly used to mount one carbon brush on commutators or slip rings. Its single leg flange mounting structure greatly reduces occupied installation space, ideal for compact machinery where multi-leg holders cannot fit. The main housing adopts high-temperature insulated phenolic resin or reinforced engineering plastic, providing excellent dielectric strength and resistance to vibration and heat. Equipped with stainless steel constant force spring, it delivers consistent pressure on carbon brush during long-term running, minimizing sparking and reducing wear of commutator and slip ring. Copper or silver-plated copper terminals guarantee reliable electrical conductivity and low heat buildup. This single leg brush holder is widely applied in wind turbine shaft grounding systems, small DC motors, auxiliary generators and other rotating equipment. Custom dimensions for brush slot are available to match different carbon brush sizes. It is a popular replacement spare part for industrial motor and wind farm maintenance.
