Brake Linings and Carbon Brushes
Lubricity in friction linings need not be a contradiction in terms. With its lubricating properties, graphite modulates the braking effect of friction linings and makes an essential contribution to braking comfort and noise reduction. The outstanding thermal conductivity properties of graphite also play an important role in friction linings.
As electrical sliding contacts in an electric motor, carbon brushes have to deliver on the highest demands when it comes to resistance to wear and oxidation, electric and thermal conductivity as well as lubricity. In this context, graphite plays a central role as an important component in many carbon brush formulas.
