Abstract

A bearing control system for a roll with hydrostatic bearings which is mounted by its axle on a bearing block or other equivalent frame member by hydraulically loaded hydrostatic bearing elements. A principal bearing element acts in a principal loading direction and another bearing element is a backup bearing element which acts in a direction opposite to the principal loading direction. The bearing elements include bearing shoes positioned freely around the axle in order to support the axle so that the roll revolves freely in relation to the bearing block or other frame member. The control system feeds a hydraulic pressure medium to the hydrostatic bearing elements so that the roll is displaceable in the principal loading direction, e.g., in the direction of the nip plane, by displacing the axle via the bearing elements.
