WZ (VarioLine) Linear Rod Units (Legacy)

VARIOLine WZ60/80 (Legacy) 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.
