Profile: Exlar Corporation manufactures roller screw linear actuators, rotary servo motors, and electronic products for motion control applications. We provide an efficient electro-mechanical replacement for hydraulic/pneumatic cylinders. Our GSX series linear actuators combine the advantages of our roller screw technology and T-LAM stator technology to create a powerful & robust linear solution. We design roller screw mechanism for converting electric motor power into linear motion within the actuator. Our 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.
