Friction discs with special design

The friction material mainly consists of cellulose, resins, carbon and other components. It is designed to have a very high coefficient of friction and lower compressibility. The special disc design improves oil flow and thus supports more efficient work. In conjunction with the material, the construction contributes to the stability of the pads and to consistent operation even under demanding operating conditions.
