An apparatus for use in a press machine eliminates the free clearances present between the threaded portions of a screw and adjustment nut assembled in a shutheight adjustment mechanism. A hydraulic assembly directs a pressurized fluid against an outer periphery of the adjustment nut to effectively compress the adjustment nut and cause its threaded portion to be displaced into interlocking engagement with the threaded portion of the screw. Alternatively, the hydraulic assembly may be arranged to hydraulically pressurize an interior space of the screw to effectively expand the screw and cause its threaded portion to be displaced into interlocking engagement with the threaded portion of the adjustment nut.

A drive disk assembly for use in a press machine is segmented into a plurality of discrete drive disk segments each having a friction pad attached thereto. The segmented drive disk permits individual disk segments and friction pads to be removed after installation without disassembling the entire arrangement. The disk segments may grow thermally without causing the flex disk being utilized to shift axially or radially. A slot formed throughout the disk segment acts as an effective heat barrier to protect sensitive parts from undue thermal exposure.
