ABSTRACT:
An adjustable bearing arrangement for the cylinder of a rotary printing press provides a fine adjustment in which a step-down in the angle of rotation of the adjusting movement of an eccentric bushing relative to the rotation of a radially slotted cylinder mounting bracket is ensured. The locating pin of the cylinder mounting is rotatably mounted in the eccentric bushing and rotation-inhibiting means for the pin is formed by a groove in which one end of a rotation-inhibiting lever is guided after the fashion of a prismatic joint, the other end of the lever being so mounted fixedly to the frame that the lever can pivot around a knuckle joint disposed parallel to the pin. The anti-friction bearings of the cylinder are disposed on the journal of the cylinder with their outer race received in a totally enclosed bearing ring having a guide pin beveled to form two flat sides, the guide pin being introduced into a slot S of the cylinder mounting and being locked therein by a spring biased detent.
