Abstract: An installation for levelling a metal strip (3) by advancing it along an undulating path in a levelling stand (10) associated with a plurality of rolls (2, 15, 16, 18) with narrowed ends which may be displaced axially in opposite directions. Narrowed sections (25) are provided at opposite ends of two active levelling rolls (23) (24), and the levelling unit (4) (5) formed by each active roll and associated carrying rollers is mounted on two horizontal beams sliding vertically and associated with jacks (39) (64) for adjusting the axial and vertical position of each levelling unit (4) (5).

Abstract: A device for axially supporting a rotating roller (1) resting axially on a fixed frame, at each end, by a contact ball bearing (3). According to the invention, the contact ball bearing (3) is mounted on the end of a support piece (5) consisting of a cylindrical insert (51) extended, on the roller side, by an enlarged base piece (52), fitting inside a recess (6) and bearing, in the axial direction, against the end wall (62) of the recess (6), by an axial bearing (66) and, in the radial direction, against the side wall (61) of the recess (6), by a rolling bearing (65) centering the insert (51) about the axis of rotation (10), the assembly being held in position by a cap (7) closing the recess (6).
