The offset press comprises a frame, at least one plate cylinder, a press cylinder, and a blanket cylinder interposed between the plate cylinder and the press cylinder, together with bearing assemblies carried by the frame and receiving the longitudinal ends of the cylinders so that each cylinder is rotatable relative to the frame about a respective longitudinal central axis. Each of the longitudinal ends of at least a first cylinder are received in a first bearing assembly and a second bearing assembly, the second bearing assembly being spaced apart from the first bearing assembly along the longitudinal axis of the first cylinder.
