Abstract

A roller for a rolling mill with a casing, a left half pivot, and a right half pivot. The half pivots in the region surrounded by the casing are constructed as a truncated cone and form a left surface on the left half pivot and a right surface on the right half pivot. The left half pivot and the right half pivot have boreholes and corresponding grooves formed on the surfaces. The half pivots are inserted in the casing and are braced with one another by at least one tie rod. An hydraulic oil in boreholes and grooves is passed into or onto the left half pivot and the right half pivot. The hydraulic oil exerts a pressure on the casing to expand the casing. With the casing expanded, the stop surfaces and the face surfaces of the casing are pressed onto one another by the tie rod.
