Abstract
Pressure processing roll with a roll jacket, the roll jacket rotatably mounted on a carrier by a bearing arrangement. The bearing arrangement has at least one hydrostatically supported bearing surface, which forms a gap with an opposing surface. A normal to the hydrostatically supported bearing surface, and therefore a normal force, has at least one axially oriented component. The bearing arrangement is acted upon by a predefined axially oriented force which substantially completely closes the gap in the absence of hydrostatic pressure in the hydrostatically supported bearing.
