Electric actuator has power to oust
hydraulics
The popular Electro-Thrust electric linear actuator range now includes a new high-power version.
Unimatic Engineers has added a high-power version to its popular Electro-Thrust electric linear actuator range The 125mm frame size version is now available in ballscrew diameters up to 50mm (10mm larger than the standard product), enabling it to produce thrust forces up to 44.5kN

Actuators take on harsh environments
The Electro-Thrust range of electric linear actuators now includes IP65 rated versions for use in harsh operating conditions, such as applications where frequent washdowns are required.
Electric actuators challenge hydraulics
With the launch of a new electric linear actuator offering thrust forces up to 44,500N, hydraulic cylinders now have direct competition in high power applications.
This makes it a ready alternative to hydraulic power in a host of applications where the compact size, ease of integration and programmable functionality of the electric actuator are significant advantages.
The ET125 electric cylinder provides stroke lengths from 100 to 2000mm, and can operate at speeds up to 1m/s.
Maximum acceleration is 10mm/s2, and typical positioning accuracy is +/-0.013mm.
Electro-Thrust cylinders are built around high quality C7 class ballscrews, and provide a high mechanical efficiency of up to 90%.
The long cylinder rod bearing allows high side load forces to be applied with less bearing deflection, and the angular contact bearings at the drive end are designed to accommodate high axial and radial forces.
A polymer bearing supports the front end of the ballscrew, eliminating vibration and run-out, so improving the positioning accuracy and extending screw life.
A precision anti-rotate mechanism virtually eliminates rod endplay and noise, and ensures smooth operation.
All standard Electro-Thrust electric cylinders are equipped with a permanent magnet, which is integrated in one of the screw nuts.
The cylinder body features two T-grooves, which allow limit and home sensors to be freely positioned along the entire length of the casing.
Both Hall-effect sensors and reed contact switches are available. Request a free brochure from Unimatic Engineers ...
