Exlar GSX Series Electric Linear Actuators

GSX Series linear actuators combine the advantages of Exlar's roller screw technology and T-LAM stator technology to create a powerful and robust linear solution. Exlar uses a specially designed roller screw mechanism for converting electric motor power into linear motion within the actuator. Planetary rollers assembled around the actuator's extending rod follow threads which are precisely machined on the inside surface of the actuator's hollow armature. Linear motion is produced in precise synchronization with the armature rotation. Because this roller screw mechanism has an inherently larger cumulative contact surface, these actuators have a much longer working life, and can handle heavier loads at higher speeds than is possible from a similarly sized unit built around a ball screw system.

• Speeds to 1016 mm/sec
• Cont. force to 51kN
• Stainless steel option

Electro-hyrostatic actuator (EHA)

The EHA converts power from electric to hydraulic to mechanical.
An electric servomotor drives a bi-directional, variable speed pump connected to the two chambers of a hydraulic cylinder. Depending on the direction of the flow, the axis extends or retracts.
In contrast to a hydraulic system, the power control is done by the pump.
Varying the speed of the pump means varying the flow or the pressure, and thus the hydraulic power.
This enables the electro-hydrostatic actuator to efficiently use energy and deliver power on demand.
Standard components for axis with power requirment up to 85 kW.
