Device for the axial shifting of rolling rolls in a rolling mill stand of a four-high type for the production of strip and/or plate, the stand being equipped with means for the reciprocal cross-over displacement of the processing rolls (10) on a plane parallel to the rolling plane, each roll (10) being borne on relative chocks (11) associated with stationary housings (12), a shifting jack (24) being included and being anchored at one end to a stationary housing (12) and at the other end to an erection element (31), jaw means (15) being included for the temporary clamping of the erection element (31) to a chock (11), the engagement surfaces of the jaw means (15) cooperating in the engagement position (15a) with engagement means included at least on the sides of the chock (11), these latter engagement means being conformed as a sliding element (28) having at least a first position and a second position in relation to the engagement surfaces (29, 30) of the jaw means (15), these first and second positions depending on the aligned and/or inclined position of the roll (10) in relation to its initial longitudinal axis (19), the engagement surfaces (29, 30) of the jaw means (15) being conformed as an arc of a circumference the centre of which (32) lies on the median plane of the relative rolling roll (10).
