WZ (VARIOLine) Linear Rod Units
VARIOLine WZ60/80 units are designed for handling applications needing increased lateral forces. As a fully integrated linear ball screw drive with a ball bearing guide system, a ram-type piston is used as the transmission of the feed force. High screw leads make it possible to combine high speed and high precision motion.
