Abstract
A rolling unit for a rolling mill for rolling or sizing metal pipes, bars or wires has at least three rolls arranged in a star arrangement. Each roll has a separate drive mechanism and is rotatably mounted on bearings on both sides of it. The rolls are adjustable radially together with the bearings. The improved rolling unit has smaller outside dimensions but can take a higher load. The number of individual rolling unit parts is also reduced as well as manufacturing and assembly expenses. For this purpose the bearings of the roll shafts are mounted in respective eccentric sleeves, whose rotational position may be adjusted manually and in a stepwise manner between several rotational positions.
