Carbon brush for power tools 6.5×7.5×13.5 100A angle grinder
Product Details
Carbon brushes transmit electric current through sliding contact between stationary and rotating components. The efficiency of rotating machinery is significantly impacted by the performance of carbon brushes, making the choice of appropriate carbon brushes crucial. Motors in power tools, compared to those in vacuum cleaners, require more durable carbon brushes. Therefore, our company has developed the RB series graphite materials tailored to the specific requirements of power tool motors. The RB series graphite carbon blocks exhibit superior wear-resistant properties, making them ideal for various power tool carbon brushes. The RB series graphite materials are highly regarded and professionally recognized in the industry, preferred by both Chinese and international power tool companies.
At Huayu Carbon, we employ advanced technology and years of quality assurance expertise in our research field to develop and manufacture carbon brushes for various customer needs and applications. Our products are environmentally friendly and suitable for a wide range of applications.
Advantages
These carbon brushes in this series exhibit superior commutation performance, minimal sparking, high durability, electromagnetic interference resistance, and excellent braking capabilities. They find extensive application in both DIY and professional electric tools, with the safety brushes (automatic shutdown) particularly well-regarded in the market.
