PDP alternative to ballscrews is made of two ground WMH pinions connected through a preload system to reduce rack and pinion mesh backlash. When mounted at the output flange of SRP, a high-tech planetary gearhead, PDP offers four different modules with straight or helical teeth, eight reduction ratios, angle drive versions, two-output pinion diameters for each size and an input interface in-line flange or with a 90° angle.
