In order to provide an adjustment of the roll gap under load with high positioning accuracy and regulation accuracy, a cross-rolling unit for adjusting rolls operating under load with, disposed on a force-absorbing roll stand, a mechanical setting unit for a first cross-roll setting and a hydraulic setting unit for a second cross-roll setting, wherein the mechanical setting unit includes two mutually displaceable mechanical subassemblies having a common axis of symmetry and the hydraulic setting unit includes at least two mutually displaceable hydraulic subassemblies having respectively one central axis, has the mechanical setting unit and the hydraulic setting unit disposed in the force-absorbing roll stand as a common subassembly. The axis of symmetry of at least one of the mutually displaceable mechanical subassemblies and the central axes of each of the mutually displaceable hydraulic subassemblies are the same.
