A carbon brush transmits current between a stationary part and a rotating part by sliding contact. As the performance of carbon brush has a significant impact on the performance of rotating machines, so the choice of carbon brush is a crucial factor. At Huayu Carbon, we develop and produce carbon brushes for a variety of customer needs and uses, applying superior technology and quality assurance know-how that we have developed over the years in our research fields. Our products have minimal environmental impact and can be used in many different applications.
The carbon brush series exhibits excellent reversing performance, minimal sparking, high wear resistance, effective anti-electromagnetic interference capabilities, exceptional braking performance, and other notable characteristics. It finds extensive applications in various DIY and professional power tools. Particularly, the market highly regards the safe carbon brush (with automatic stop) for its outstanding reputation.
