FIELD: process engineering.
SUBSTANCE: invention relates to metallurgy. Proposed stand comprises solid body with three openings and three rolls that make pass with individual drives fitted on sleeve fitted on hollow shaft, two radial rolling bearings and one bearing taking up axial loads, as well as tie rod arranged inside hollow shaft and engaged therewith by toothed coupling with nut, on one side, and face washer, on opposite side. Extra radial bearings are fitted in sleeves on radial bearing outer side. Through cylindrical holes are made in stand body parallel with pass axis to receive wedges interacting with outer surface of extra radial bearings. Tie rods are provided with plate springs on toothed coupling side and, on opposite side, they are provided with hammer heads to be fitted in cylindrical and oval grooves made in face washers. Sleeves with radial rolling bearings taking up axial loads and extra radial bearings are fitted on hollow shaft.
EFFECT: higher rigidity of pass and precision of its processing.
