In an apparatus for fixing a roll ring 4 on a roll shaft 2 mounted in two parallel roll stands 1a, 1b on both sides of the roll ring, by means of a tensioning means 18 and an axially tensionable conical sleeve 8 a radial tension is generated in the roll ring 4. In addition, the conical sleeve 8 carries the roll shaft bearing 3a. To enable the axial and radial tensioning of the roll ring 4 to be adjusted simply and accurately in spite of the additional roll shaft bearing 3a, the tensioning means 18 acts on the one hand on the conical sleeve 8 via a first thrust transmitting means passing through the roll stand 1a and on the other hand on the roll ring 4 clamped between two thrust rings 22, 23 via a second thrust transmitting means passing through the roll stand, one of the two thrust transmitting means also receiving the roll shaft bearing 3a. |
