ABSTRACT:
The elements of an axially-aligning, eccentrically-adjustable, three-ring anti-friction roller bearing are arranged to compensate for inevitable small deformation and bore alignment errors for the journals of blanket cylinders of printing presses. Rows of rolling elements are disposed between the three bearing rings, the outer one of which has an arcuating curved swing surface. For the purposes of increasing the radial rigidity of the anti-friction mounting and for taking radial forces, the roller bearing rows include cylindrical roller bearings. In addition, there are provided, at least at one axial end, ball bearings or cross-roller axial bearings to resist axial forces. The three bearings rings are braced relative to one another axially and/or radially by a lock nut or the like threaded on the journal for urging the inner bearing ring against the bias of a spring engaging a shoulder on the journal on the other side of the bearing.
