Overview

The PSD Precision Screw Driven actuator is a linear motion system that combines Hepco’s Herculane® wheel technology with a lead or ball screw drive for excellent accuracy and performance in a cost effective package. This off-the-shelf solution reduces design and installation costs by easily integrating into machine configurations that require accurate positioning in a compact environment. The PSD is ideal for single or multi-axis applications and is particularly useful in Z-axis applications. PSD comes in two sizes, 80mm and 120mm, and is available in a large range of stock lengths. An assortment of options and accessories are available including Z-axis mounting plates, tubular flange screws, and a wide variety of motor connection kits and screw pitches.
