<p>In a roller (1), in particular a working or support roll for a rolling mill such as a plate rolling mill, flat rolling mill or the like; comprising - a sleeve (2); - a left half-pin (3); and - a right half-pin (4); - wherein in the region surrounded by the sleeve (2), the half-pins (3, 4) are configured as truncated-cone-shaped and form a left surface (12) on the left half-pin (3) and a right surface (13) on the right half-pin (4), the left half-pin (3) and the right half-pin (4) is configured with holes (24) and grooves (11) corresponding therewith, wherein the grooves (11) are formed on the surfaces (12, 13). The invention also relates to a method for producing a roller (1), in particular a working or support roll, whereby - the left half-pin (3) and the right half-pin (4) are inserted in the sleeve (2); - the right half-pin (3) and the left half-pin (4) are braced with respect to one another by means of at least one tie rod (5); - hydraulic oil in holes (22) and grooves (11) is guided into or onto the left half-pin (3) and the right half-pin (4); - the hydraulic oil exerts a pressure on the sleeve (2), by which means the sleeve (2) is expanded; and - when the sleeve (2) is expanded, the stop faces (18, 19) with the front faces (20, 21) of the sleeve (2) are pressed onto one another by means of the tie rod (5).</p> |
