Linear actuators and screw jacks move objects along a straight path and are used in systems and applications requiring lifting, lowering, shifting, or tilting movement. They are easier to install, maintain, and operate than pneumatic or hydraulic actuation systems. Linear actuators integrate with motors to provide precise control and positioning. Actuated linear motion systems are used in automated applications for straight-line movement. Motorized linear lead screw actuator systems are self-contained units with a motor providing linear motion as it traverses along the lead screw. Actuator accessories expand the capabilities of specific brand and series linear actuators.
