Abstract: In a hydraulically supported roll including a rotatable hollow cylinder and a stationary crosshead, transverse end seals are provided to seal a longitudinal chamber formed in the clearance space between the crosshead and the hollow cylinder. Each transverse end seal includes a roller bearing having a first bearing ring rotatable with the hollow cylinder and a second bearing ring mounted on the crosshead. The first bearing ring includes a first surface, which along with a second surface formed on a ring secured to the crosshead, defines a clearance gap. The gap has a width of less than 0.1 mm. The first bearing ring seals the longitudinal chamber at the inner circumference of the hollow cylinder and the first and second gap defining surfaces are located on parts that are axially restrained with respect to the crosshead.
