A gauging device for a metal working machine comprising two parallel hollow sections separated by a predetermined distance and having disposed therewith in use ball screw drives for each section having a pulley engaged with an endless belt, the endless belt (preferably a nylon covered steel core belt for example as manufactured by Breco-flex of Germany) driven by a separate servo motor having a second pulley engaged therewith, preferably the belt being engaged with an idler pulley on each side of the servo motor, whereby the one servo motor drives both ball screw drives each disposed with one of the two hollow sections. The center to center spacing of the ball drives is not as critical as with conventional known methods of linking drives, i.e. shaft and right angle gear box and drive shaft arrangements.
