A printing unit for a web-fed rotary printing machine is provided having at least one carrying wall, a plurality of cylinders mounted on the carrying wall, a drive motor corresponding to each cylinder and a slide corresponding to each cylinder. Each slide carries its corresponding cylinder and receives the corresponding drive motor. A drive means is provided for driving the slides and a plurality of guide elements are mounted on the carrying wall and arranged laterally next to the adjacent end faces of the cylinders for guiding the slides along the wall. The guide elements are arranged opposite and parallel to one another on the carrying wall. Optionally, the carrying wall includes panels defining an orifice to allow cylinders, journals and sleeves of the printing machine of varying sizes to be changed readily.
