Abstract
In a deflection controlled roll (1) having a non-rotatable carrier (4), a rotatable roll jacket (7) is supported against the carrier (4) by a number of hydrostatic supporting elements (8) with adjustable pressing force. The supporting elements (8) run in corotating bearing races (9) mounted loosely in the roll jacket (7) and corotating with the roll jacket (7) but independently therefrom. These bearing races (9) are provided on both sides with flanks (15) for axial positioning, which cooperate with side bearing pockets on the supporting element (8) and form an axial guideway for the bearing race (9). Automatic positioning with maintenance of a defined bearing gap is achieved by a toroidal cross-sectional or a tapered ring-shaped construction of the running surfaces of the supporting element (8) and the bearing race (9).
