ABSTRACT:
A shaft bearing for mounting the shaft ends of a rotating workpiece to be machined, especially an intaglio printing cylinder, has a rotatably mounted clamping chuck clamping the shaft end and having a hollow clamping head. The clamping head has gripping parts mounted so as to be radially adjustable relative to the longitudinal axis of the clamping head. Each gripping part is mounted rotatably about a pivot axis extending parallel to the longitudinal axis, and is guided, in a region distant from the pivot axis, along an arcuate guide track extending around the longitudinal axis. Each gripping part is configured so as to extend at a decreasing distance from the longitudinal axis and being movable relative to the guide track for the purpose of clamping the shaft end.
