Patent ID: 8511905

Claim:
A printing press, comprising: a roller having a first antifriction bearing and a second antifriction bearing; said first antifriction bearing having rolling bodies, a first ring and a second ring, one of said rings forming an outer ring and the other of said rings forming an inner ring, said inner ring and said outer ring each having a respective rolling body running face; said first antifriction bearing being configured as an axial floating bearing with a considerable axial movement play of said rolling bodies between said rolling bodies and one of said rings; said second antifriction bearing being configured as an axial locating bearing with a negligible axial movement play; roller sockets configured as quick action changing devices for receiving said first antifriction bearing and said second antifriction bearing during insertion of said roller into the printing press, said roller sockets having a basic body, said basic body having only two contact faces; a centering device for centering one of said rings, relative to the other of said rings, said centering device having at least one centering element, said centering element for displacing one said respective rolling body running face relative to another said respective rolling body running face into an aligned position in which said rolling body running faces are aligned on a common radial alignment line; and a clamping element for clamping said first antifriction bearing into said one roller socket, said clamping element being a clamping lever having only one contact face; said at least one centering element being formed on one of said roller sockets or said clamping element; in a clamped position of said clamping element, said one contact face of said clamping lever pressing said outer ring of said first antifriction bearing against said two contact faces of said basic body for holding said outer ring by bearing only against said two contact faces of the basic body and said one contact face of said clamping element.
