Patent ID: 7661360

Claim:
A device for supporting a cylinder of a printing unit including cooperating cylinders comprising: a printing unit frame a bearing unit mountable as a modular unit on said printing unit frame and having a bearing unit length; linear bearing elements in said modular bearing unit, and including a pair of spaced, fixed linear bearing elements securable to said printing unit frame and movable linear bearing elements which are movable in said fixed linear bearing elements and with respect to said printing unit frame; a bearing block supported directly by said movable linear bearing elements and being supported between, and movable with respect to said pair of fixed spaced linear bearing elements in said bearing unit in an actuating direction, which actuating direction coincides with a plane defined by axes of rotation of said cooperating cylinders; a rotary bearing positioned in said bearing block and between said pair of spaced fixed linear bearing elements, said rotary bearing being adapted to receive an end journal of said cylinder to be supported by said modular bearing unit; a drive in said modular bearing unit and usable to provide relative linear movement between said bearing block, which is supported between said fixed linear bearing elements of said modular bearing unit which are fixed on said frame, and said movable linear guide elements of said modular bearing unit and which directly support said bearing block and which are movable with respect to said frame; and a diameter of said cylinder, said length of said modular bearing unit in said plane being not greater than said diameter of said cylinder.
