Carbon brushes conduct electricity between stationary and rotating components through sliding contact. The selection of carbon brushes is critical because their performance significantly impacts the functionality of rotating machinery.
Huayu Carbon's vacuum cleaner carbon brushes are highly praised by customers and currently supplied to renowned international brands such as Midea and LEXY.
Huayu Carbon ensures quality assurance through advanced technology and years of research, tailored to different customer needs and applications. Our products have minimal environmental impact and are suitable for a wide range of applications.
I do not recommend using alternative versions of carbon brushes in these precise and expensive machines. Inferior or low-quality carbon brushes can cause intense sparking, which may damage the commutator and lead to further serious issues. This is why using genuine carbon brushes is essential, as they not only ensure longer replacement intervals but also extend the lifespan of power tools.
Huayu Carbon's vacuum cleaner carbon brushes are characterized by their low contact pressure, low resistivity, minimal friction, and capability to handle a wide range of current densities. These brushes are engineered to compress within the GT plane to precise dimensions, making them an ideal choice for cost-effective appliances operating at voltages up to 120V.
