INVENTORS: EUGEN SCHNYDER and ROBERT LEU INVENTION: GUIDE BEARING ARRANGEMENT FOR THE SHELL OF A PRESS ROLL ABSTRACT OF THE DISCLOSURE The press roll comprises a roll shell which is rotatably arranged about a stationary beam and is movable relative to the latter by means of pressure adjusting elements provided therebetween, the movement being effected over the entire length of the roll shell and along the pressure or rolling plane. In order not to veer from this pressure or rolling plane, there is provided a guide bearing arrangement which comprises, between the roll shell and the stationary beam, a bearing having an inner ring and an outer ring, guide elements being assigned to this outer ring for guiding the latter in a direction which is essentially parallel to the pressure or rolling plane. The inner ring of the bearing is fixedly mounted at the outer surface of a substantially ring-shaped or annular portion or sector of the roll shell. The outer ring of the bearing supports two gibs - 1 - or rails which are arranged substantially parallel to a plane of the axis of the outer ring and which form therebetween guiding surfaces of an elongated guide cam. At the stationary beam there are provided two guide surfaces, the spacing between the two guiding surfaces of the elongated guide cam being adapted for sliding play fit or clearance seating to the distance between the two guide surfaces provided at the stationary beam. In this manner, it is ensured that the outer ring of the bearing is nonrotatable. However, along with the outer ring of the bearing, the roll shell rotatable relative to the outer ring is displaceably guided in a direction substantially parallel to the pressure or rolling plane. - 2 -
