A printing press having inboard cantilevered cylinder supports is disclosed. The press includes a frame with a drive side spaced from a non-drive side, and the press includes a cylinder defining an having an axis and having a drive end and a non-drive end. The drive end includes a drive aperture extending axially into the cylinder and a splined insert mounted within the drive aperture, while the non-drive end includes a non-drive aperture extending axially into the cylinder. A drive shaft is rotatably mounted to the drive side of the frame and is arranged for connection to a power source. The drive shaft includes a spline sized to engage the splined insert and is arranged to a portion of the cylinder, while a mandrel carried by the non-drive side of the frame extends into the non-drive aperture and is arranged to support another portion of the cylinder.

Inboard cantilever cylinder support for printing presses

To modify an existing printing press from its original length/cut off to a different cut off, a sub-frame may be mounted on an existing frame of a printing press. The sub-frame permits the relocation of bearing supports for various printing cylinders, such as, for example, the plate cylinders and blanket cylinders. In addition to mounting the sub-frame on the existing frame, new plate and blanket cylinders having different sizes than the plate and blanket cylinders used in the existing printing press may be mounted in the sub-frame to provide different printing lengths/cut offs. Suitable sleeves, such as the eccentric mounting sleeves may be provided as necessary in order to mount the cylinders to the sub-frame.
