Electric servo-cylinder GSX series

roller screw linear

High Capacity Roller Screw Actuator for Long Life! 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.
