ABSTRACT:
A roll assembly for reducing rod and the like in which the rolls are secured against rotation on their arbor by force applied to the sides of the rolls in the direction of the axis of the arbor. The force is applied by an hydraulic nut or annulus having a cavity which is sealed pressure tight by a deformable membrane. An annular shoe is interposed between the membrane and the rolls. The cavity is supplied with fluid under pressure and is deflected exerting force on the shoe which is transmitted to the roll.
