Abstract
A roll stand for the rolling of rolling stock, especially metal products. The roll stand includes at least two chocks for mounting at least one roll, the roll being rotatably mounted in the chocks by its two cylindrical roll necks. A cylindrical neck bushing is arranged on the roll neck with radial play. A rotationally fixed annual axial bearing is axially offset from the neck bushing. The bearing arrangement for the roll necks in the chocks is formed as a plain bearing, preferably a hydrodynamic oil film bearing. When subjected to a load in a rolling process, the neck bushing moves and deforms not only in the radial direction, but also in the axial direction.
