What is the difference between red, green, purple or blue paint marks on the friction facings?
Nexen offers a variety of friction materials; this means the torque of Nexen products can be tailored to the application needs. Each material has a specific friction coefficient. The higher this friction coefficient, the higher the torque your unit will produce but also the higher the wear on the disc and the friction lining. Lower friction coefficients will reduce the wear in a very significant way and will also reduce the noise levels. Our catalogues and web site only post the static torque of the component fitted with standard facings (unless otherwise specified) to calculate the torque of the other versions please see the graph and the table below.
