Exlar GSX and GSM linear actuators

Exlar’s GSX and GSM linear actuators now offer Class I, Division 2 certification. Suitable for process control valve and damper applications, the linear actuators provide continuous hold on the position of the valve stem or shaft. This allows for a fast response to small command signal changes without overshoot - even when friction is present. This design results in improved loop performance and reduced process variability.

To meet application requirements, the Class I, Division 2 linear actuators are also available with resolver feedback and handwheel options. Additional features include T-Lam segmented lamination stator technology, providing increased, continuous motor torque; up to 83 cm/s linear speeds; and a terminal box with NPT ports.

GSX series actuators combine a brushless servomotor, an inverted roller screw and an encoder/resolver feedback source into a single compact assembly, eliminating the cost and complexity of a system’s engineering approach. This design allows these actuators to be used in closed loop servo systems, where electronic control of positioning and velocity is required.

The GSM series of linear actuators provides a cost-effective solution for replacing ball screw actuators, offering up to five times the travel life in a completely integrated actuator. Incorporating the company’s roller screw technology with an integral brushless servo motor, the GSM series delivers a smaller package with higher speed and load capacity for medium- to high-performance motion control applications.
