In a variable crown roll for a rolling mill, an annular cavity of a predetermined depth is formed between an arbor (1) and a sleeve (2), a pressure transmitting medium, e.g. oil or water, is forced into the cavity through a passage in the arbor, and the pressure of the medium is adjusted to control the value of crowning of the roll. The cavity has an inlet at one end and an outlet at the other, and is of a radial depth greater than the maximum expected deflection of the sleeve. <IMAGE> |
