The segments (2) have clamping shoulders (5) which extend around the front faces, the segments (2) being releasably fastened at each front face to the roller core (1) by means of at least one fastening ring (6). Said fastening ring fits over the clamping shoulders (5) of the segments (2). The fastening ring (6) is or can be clamped against the segments (2) by means of axially parallel clamping bolts (7). Each segment has at least one axially parallel opening for the clamping bolts which, relative to the extension in the circumferential direction, is arranged between the two lateral faces (3) of the segment (2).
