Overview

Quick Data

GSM Series

GSM Series electric linear actuators are a superior and cost effective alternative to traditional electric, hydraulic and ball screw systems. The compact design is the culmination of advanced roller screw technology and an integral brushless servo motor. This robust electric linear actuator is ideal for a variety of medium- to high-performance applications. With GSM actuators, everything from food and beverage packaging, to multi-axis turning centers, to aircraft assembly can be done cleaner, faster, and more accurately and efficiently.

 

More Torque and Greater Flexibility

The powerful T-LAM motor design generates 35% more torque from the same size package. These innovative actuators can be driven by almost any brand of brushless servo motor amplifier. This flexible and programmable motion control system has the capability to provide position feedback from resolvers, encoders or internally mounted sensors. It is a power dense solution that accommodates greater loads, extends travel life and minimizes maintenance. GSM by Exlar® is the new standard of excellence in standard capacity all-electric actuators.

 

Other Advantages

  • Integrated motor and actuator in a single compact unit
  • Designed for closed loop servo systems
  • Sealed housing for long life and minimum maintenance
  • Compatible with nearly any servo amplifier
  • Maximum slot fill for maximum motor performance
  • 100% continuous duty cycles
