FIELD: technological processes.
SUBSTANCE: invention relates to rolling, specifically working roll stands of hot and cold rolling mills. Roll includes a bearing profiled axis with a limiting collar shifted relative to the roll axis of rotation, and a mate of mating shape conjugated to it with interference fit. Shaped axis is made of two axially symmetric sections joined without benches, one of which adjoins the limiting collar, and the other is spaced from it. Both sections of the bearing axis have a single axis of symmetry, the section adjoining the limit collar is made cylindrical, and distant – in the form of a truncated cone, the generatrix of which is inclined to the axis of the roll at an angle determined by a mathematical expression.
EFFECT: easier machining of the roll and low cost thereof.
