The carbon brush plays the important role of sending electrical current between motionless and rotating parts by sliding contact. Since the performance of the brush has significant impact of the performance of rotating machine, the choice of brush is a critical factor.
Toyo Tanso Group develop and produce carbon brushes for a variety of customer needs and purposes, applying the superior technology and quality assurance know-low that we have developed over our many years of research in the fields.
Carbon has self-lubricating properties and low coefficient of friction due to its layered crystal structure, making it highly abrasion resistant.
With its excellent electrical conductivity, carbon can offer a stable, optimal level of electrical resistivity, which is enhanced by appropriate selection of materials and production process.
Carbon has low coefficient of thermal expansion, which means that it hardly has changes in shape or quality even at high temperatures.
