At least one group of cylinders includes a printing block cylinder. The cylinders are connected to a train of drive wheels. The printing block cylinder drive wheel (21) is pivot mounted on a support (31) positioned on the steering stub axle (30) of the printing block cylinder via a first angular ball bearing (32). A support ring (33) supporting a first crown gear (38) is connected to a printing block cylinder drive wheel by means of a second angular ball bearing (34). An inner piston (37) is connected to the outer ring of the first angular ball bearing and is axially movable on the support between the angular ball bearings. An axially movable outer piston (39) supporting a second crown gear (40) is positioned on the inner piston. A circular ring cylinder (41) is formed connected to a pressurized medium source. The outer piston is joined to the support by an annular membrane (42). Springs (43) supported against the membrane are axially active in the inner piston.
