ABSTRACT A roll is provided comprising a rotating hollow roll forming a working circumference and having a stationary crosshead extending therethrough to form a clearance gap therebetween. The entire clearance gap is filled with pressurized fluid. In the crosshead cylinder-like bores are provided with piston-like sealing elements displaceable therein to rest against the inner circumference of the hollow roll. The elements optionally may exert against the inner circumference of the hollow roll a higher or lower pressure relative to the pressure in the gap to create a line pressure or lifting force for shifting the hollow roll in the effective plane.
