Patent ID: 7699000

Claim:
A device for mounting a cylinder on a side frame of a printing unit comprising: a radial bearing supporting a journal of said cylinder for rotation about a cylinder axis of rotation; a bearing block supporting said radial bearing; linear bearings supporting said bearing block for movement along a direction of adjustment of said cylinder toward and away from an adjacent cylinder having an adjacent cylinder axis of rotation, which direction of adjustment is perpendicular to said cylinder axis of rotation, which direction of adjustment forms an acute angle of not greater than 15° with respect to a plane defined by said cylinder axis of rotation and said adjacent cylinder axis of rotation; a bearing unit including said radial bearing, said bearing block and said linear bearings, said bearing unit forming a complete structural unit; a bearing unit support, at least one of said linear bearings being stationarily fixed to said bearing unit support and wherein said side frame has at least a partial overlap with an end surface of said cylinder when said cylinder is supported by said bearing unit in said side frame; a fluid pressure operated actuator in engagement with said bearing block and usable to move said bearing block in said bearing unit along an adjustment path in said direction of adjustment into a print-on position in contact with said adjacent cylinder in response to an application of a fluid pressure medium to said actuator; and a bearing block travel limitation device in said bearing unit support and usable to limit a length of said adjustment path in said direction of adjustment toward said adjacent cylinder, said travel limitation device being operable independently of said fluid pressure operated actuator.
