Abstract
A cylinder device includes a deflection-controllable cylinder having a rotating hollow cylinder which is longitudinally traversed by a crosshead. Crosshead sags when subjected to a load. The ends of the crosshead, which protrude from the hollow cylinder, are supported by bearings in the cylinder housing that include flat slide surfaces which interact, are hydraulically relieved of load, and absorb the elongation of the crosshead. Also, where applicable, spherical surfaces which interact, are hydraulically relieved of load, and absorb the deflection of the crosshead.
