To permit slight tilting adjustment of a bearer ring with respect to the shaft of an associated printing cylinder upon interposition of a layer of resilient, shock-absorbent, wear-resistant material between the shaft and the shaft-receiving opening of the bearer ring, and to allow for inaccuracies of fit due to this elastic insert, the bearer ring is formed with openings therethrough in alignment with similar openings formed in the end face of the associated cylinder, exact positioned alignment between the bearer ring and the printing cylinder being obtained by introducing adjustment pins through these openings, the adjustment pins having relatively eccentrically offset sections in the bores of the bearer ring and the printing cylinder so that, upon rotation of the eccenter pins, exact concentricity of the bearer ring and the printing cylinder can be obtained.
