<p>A shutheight adjustment mechanism of a mechanical press including a piston member restrained from moving vertically by a sealed liquid-filled chamber of relatively short height. The chamber acts as a stiff liquid-spring that limits deflection and movement of the piston member and ultimately the slide or bolster. Seals define the chamber to assure that the chamber is filled with liquid. The liquid-filled chamber damps free movement between parts thereby helping to resist changes in shutheight. Liquid also is injected between the piston member and both the adjustment nut and the housing. This liquid reduces torque requirements for shutheight adjustment.</p>
