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.

PRECISION PICK & PLACE SYSTEM
Actuators Offer Positional Accuracy and Repeatability
THE CHALLENGE:
The application is a manually intensive process that requires precision placement of component parts into multiple receptacle profiles. They require significant force to insert and are repetitive in nature. There are three main universal components that need to be assembled to form the push fit connector. First, the ‘O’ ring seal is inserted into the receptacle base, followed by a cartridge and finally the collet. Once assembled, these components form the push fit pipe-fitting. The high demand for the products has further added to the company’s drive to increase production.
