An adjusting cylinder for long, rapid lifting movements in rolling stands, includes vertical edging stands, wherein each cylinder has at least one piston, which acts through the bearing chocks of at least one work roll or of an interposed roll to adjust a work roll on both sides, wherein each adjusting cylinder has a piston that is equipped with two oppositely directed piston rods, and each piston is inserted in a recess in the cylinder base or cylinder cover, such that the base and cover have coaxially arranged bores through which the piston rods pass. The surface formed by one piston and the piston rod is smaller than the surface formed by another piston and the piston rod.
