ABSTRACT:
A shutheight adjustment mechanism of a press including a male threaded member threadedly engaged to a female threaded member with a clearance space therebetween is flooded with a liquid to reduce undamped free movement between the threaded members. Liquid injected in the clearance space causes a squeeze-film to be created, capable of supporting high impulse working loads. Seals define the clearance space to assure that the entire clearance space is filled with liquid. In one embodiment, the shutheight adjustment mechanism is included in the press slide.
