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.

The invention concerns a drive spindle () for the main drive of a rolling stand, which has: a first shaft () for transmitting torque from a drive motor () to a coupling element, especially to a multiple spline profile, and a second shaft () for transmitting the torque from the coupling element, especially the multiple spline profile, via a swivel joint () to a roll () of the rolling stand, wherein the swivel joint () has a wobbler (), which is rotationally rigidly connected with the roll (), and a second spindle head (), which is rotationally rigidly connected with the second shaft (), and wherein the rotational connection between the wobbler () and the spindle head () is produced by sliding bearings and a journal (), which is rotationally rigidly connected with the spindle head () but is supported in a way that allows an angle of inclination (&#x3b1;) between the axis of rotation () of the roll () and the axis of rotation () of the second shaft (). In order to achieve improved transmission of axial forces by the swivel joint, the invention provides that a bearing element () for absorbing forces in the direction of the axes of the second shaft () and the roll () is arranged between the wobbler () and the spindle head (), such that a push rod () for transmitting axial forces between the wobbler () and the spindle head () is arranged between the two bearing elements ().
