    The invention concerns a press roll having adjustable sag capability, principally for use in paper making machinery, or the like. The press roll includes a hollow, rotatable shell supported by a non-rotatable yoke and hydraulic support elements between the shell and the yoke transfer the press forces from the shell to the yoke. Each end region of the yoke is supported by a stationary support block. The connection between the yoke and the stationary support block is at a particular location. A mating roll cooperating with the press roll is supported by bearings longitudinally positioned approximately at the location of the connection between the support block and the yoke. An additional hydraulic supporting element is defined between the roll shell and the yoke and the longitudinal location of the yoke support piece and the mating roll bearing. The roll shell is supported on a stationary guide element with respect to which the roll shell rotates. The guide element permits the yoke to shift under the pressure, but prevents the yoke from rotating. The length of the roll shell is sufficient to extend into the region where it can be supported by the supporting element. The particular yoke support provided comprises a stationary support block and a tubular cantilever member that extends between the roll shell and the yoke. The yoke bears against the inside of the cantilever member while the roll shell bears against the outside. Packings are provided for sealing the roll shell on the support block. Finally, a planetary gear arrangement located inside the roll shell serves to drive the roll shell to rotate with respect to the yoke.
