Abstract
Sliding bearings for chocks (11) in back-up rolls (12) under load, the back-up rolls (12) cooperating with the respective working rolls (112) and being able to perform crossed displacement in a four-high rolling mill stand for the hot rolling of sheet and/or large plate, the chocks (11) cooperating on the outside with organs to transmit the load from the rolls to the stationary housing (21) and organs to regulate the gap between the working rolls (112), these organs comprising millscrews, hydraulic capsules (13), spacers, etc., the bearings comprising a revolving bearing with conical, truncated cone or barrel-shaped rollers arranged in an intermediate contact position between a lower sliding element, attached to the chock, and an upper sliding element solid with the relative organs to transmit the load, the top or the smaller base of the rollers facing the chock opposite the one with which they are associated, the rollers being disposed radially to define a circular section the center of which is defined by the vertical projection of the center of rotation of the relative back-up roll.
