A roll with rotating shell comprising a fixed support beam (2), a tubular shell (1) rotatably mounted on the support beam (2) about an axis, a plurality of shoes for holding the shell distributed side by side along the length of the beam in an axial bearing plane (P), each shoe (3) being slideably mounted radially between the shell (1) and the support beam (2) and connected to an arrangement (21, 33) of regulating thrust and to an arrangement (51, 55) of introducing continuously a lubricant into the gap (52) between the bearing face (31) of the shoe and the internal face (13) of the shell. Each shoe (3) is provided, on the part (36) of its bearing face (31) which is turned upstream with respect to the direction of rotation of the shell (1), with an arrangement (6) of centering by lateral bearing on the internal face (13) of the shell in a radial direction (D) inclined with respect to the bearing plane (P) and under sufficient pressure to cause a transverse shift in the shoe and to create the effect of a wedge at the downstream end of the latter. The invention applies in particular to rolling mills used in the metallurgy industry to produce sheets or sheet metal.
