Abstract

A cutting roller has an axle (2), on which a cutting ring (4) is rotatably guided by a bearing device (10, 12). The bearing device is sealed against the environment by a sealing device (28, 30). By a compensating device (40), any differential pressure between the bearing device (10, 12) and the environment is compensable.
