A support for a cylinder of a rotary printing press comprising:
- a cylinder barrel having a cylinder barrel length and a cylinder barrel diameter and a lateral barrel face and with a cylinder journal extending from said lateral barrel face:
- a lateral frame having an inner frame face;
- and
- a bearing having a bearing inner diameter, a bearing outer diameter and a bearing length defined by bearing inner and outer end faces, said bearing being arranged completely outside of said lateral frame and receiving said cylinder journal, said bearing inner end face being spaced from said lateral frame inner face by a first distance and at a second distance from an adjacent lateral barrel face wherein said first distance is less than said bearing inner diameter and further wherein a ratio of said cylinder barrel diameter to said second distance is greater than or equal to 15 and wherein a ratio of said cylinder barrel length to said barrel diameter is between 8.5 to 9.5.
