Generally dry-running clutches and brakes use a pair of plates consisting of "organic" friction lining on one plate and a counterplate of steel or special cast iron. Although this friction combination is subject to wear, it has become a standard due to its hard wearing capabilities. Sintered, metallic friction linings are also used for particular applications. The friction linings described here are riveted or bonded to the plates in the form of rings or segments or are applied by a sintering process.
