In a rolling stand (), especially a plate rolling stand, with a right housing column (), a left housing column (), an upper column crosshead () that connects them, at least one pair of work rolls and one pair of backup rolls and associated chocks, a balancing device with brackets () and a piston rod () that extends upward through the column crosshead () beyond the upper surface () of the column crosshead (), the piston rod () has a yoke () at its outer end (), which yoke () is oriented in the rolling direction and engages the brackets () of the balancing device, and a rotating sleeve (), which encloses the piston rod (), is arranged between the upper edge () of the balancing cylinder () and the lower edge () of the yoke (), is supported on the column crosshead (), and has at least one open slot () into which the yoke () can drop.

An overload safety coupling, especially for the main drivetrains on rolling stands, which bridges a toothed spindle section and a spindle section with a permanent seat. The coupling includes a rotating-and-sliding sleeve, which has internal toothing at one end to hold the spindle section in a way that allows axial displacement. At the other end, the sleeve holds an inner sleeve, which is permanently seated on the spindle section. A pressure sleeve and a pressure gap pretensioned with pressure fluid produce a nonrotatable connection between the rear sleeve-like extension and the inner sleeve, which frictional connection gives way in the event of an overload.
