According to the invention, the bearing assembly has a supporting device, by means of which the bearing assembly can be axially supported in the roll stand.

Roll stand

An adjustment device for adjusting a roll in a roll support () of a roll stand includes a cylinder housing () that can be secured to a roll support (), and a piston () guided to move translationally in and across the roll support. The position of the piston () can be determined via a travel measurement device () connected to a coupling rod () secured directly to the piston (). The piston () has a guide element () extending from the piston head () into a bore in the roll rack and in the direction toward the travel measurement device (). The coupling rod () is secured to the guide element (). To reduce the sensitivity of the adjustment device to a tipping, the guide element () is guided in a guide opening () of the cylinder housing (). A sliding guide () is provided for the coupling rod (), which can be arranged on an end of a borehole () in the roll rack facing the travel measurement device ().
