The slide bearing elements are provided with hydraulic fluid feeding means for loading the slide bearing elements with a hydraulic fluid. The roll is intended to form a nip together with a counter roll. The hydraulic fluid feeding device is provided with control elements, whereby the slide bearing elements ( ) acting in the direction of a nip load (F) are loadable in such a way that the roll shell ( ) is able to perform a stroke relative to the roll shaft ( ) radially of the roll or to remain substantially immobilized relative to the roll shaft ( ).
