An electric linear actuator is used primarily where an intermittent axial movement and positioning is needed. It is a good alternative to hydraulic and pneumatic cylinders due to the simple connection to electrical operational systems and the hygiene benefits. Electric Linear actuators we offer is based on a worm gear drive. Such actuator is simple and of a sturdy construction. It is based on our worm gearboxes on which a set of cylindrical aluminum tubes and an inner threaded spindle are mounted.
