ABSTRACT:
A sealing element for a hydrostatically supported roll having bending control is disclosed in which a row of sealing elements is provided in a stationary crosshead for supporting a rotatable hollow cylinder arranged around the crosshead. Each of the sealing elements has a contact surface, including an enclosed circular rim, for abutting the inner circumference of the hollow cylinder. First ducts having a large cross sectional area are connected with a fluid supply line for supplying hydraulic fluid to a hydrostatic pressure chamber formed inside the rim. A cylinder volume is formed in the sealing element between the end of a longitudinal bore in the sealing element and a piston, which includes a central passageway connected with a second, separate fluid supply line. The piston is fixedly mounted to the crosshead and arranged in the cylinder volume. The cylinder volume is connected via second restricted ducts with respective rim chambers, which may be formed in the enclosed rim or radially outside same, for throttling fluid supplied to the rim chambers. The hydraulic fluid in the rim chambers forms a liquid film on the inner circumference on the hollow cylinder over which the sealing element uniformly abuts the inner circumference.
