Description

Double-leg carbon brush holder is a robust brush holder assembly designed with dual mounting legs for fixed installation of single carbon brush. The double flange mounting structure greatly improves stability, making it suitable for equipment operating under strong vibration conditions. The holder housing is constructed from high-temperature phenolic resin or reinforced engineering plastic, featuring excellent insulation, heat resistance and mechanical strength. Equipped with stainless steel constant force spring, it keeps uniform pressure on carbon brush during long continuous operation, reducing electrical sparking and minimizing wear of commutator and slip ring. Copper or silver-plated copper terminals ensure outstanding electrical conductivity and low heat generation. This double leg brush holder is commonly used for generator slip rings, large DC industrial motors and wind turbine shaft grounding systems. Custom brush slot sizes are available to match various carbon brush specifications. It serves as a reliable replacement spare part for heavy-duty rotating machinery maintenance.
