ABSTRACT OF THE DISCLOSURE A sealing arrangement for a roll having a stationary crosshead extending through a rotating hollow roll, which forms an outer working roll circumference, includes longitudinal seals and transverse end seals disposed against the inside circumference of the hollow roll. The seals form at least one longitudinal chamber in the annular clearance space between the crosshead and hollow roll. The longitudinal chamber may be filled with pressure liquid for supporting the hollow roll. Each transverse end seal has a relief chamber formed by a recess in the side of the transverse end seal facing away from the longitudinal chamber and a shoulder of a circumferential slot in the crosshead in which the transverse end seal is disposed. A pressure chamber is formed between the bottom of the circumferential slot and the bottom side of the transverse end seal. Both chambers are in fluid communication with the longitudinal chamber.
