A linear actuator is a mechanical device that converts rotational motion from an electric motor into precise linear movement, typically using a ball screw or timing belt mechanism. It works by rotating the screw or pulley, which moves a nut or carriage along the actuator body in a straight line with controlled speed and position. In industrial automation, linear actuators perform tasks such as pushing, pulling, lifting, positioning, and indexing components with high repeatability and accuracy. They are controlled by servo drives or stepper controllers that receive commands from a PLC or motion controller to execute precise movements.

A ball screw linear actuator uses a threaded screw with recirculating ball bearings to achieve high thrust capacity and excellent positioning accuracy, making it ideal for heavy loads and precision applications. A belt-driven linear actuator uses a reinforced timing belt and pulleys to produce faster travel speeds and longer stroke lengths, but with lower thrust capacity and slightly less rigidity. Ball screw actuators typically offer better repeatability and are suited for machining and pressing operations, while belt-driven versions excel in high-speed pick-and-place, sorting, and assembly applications.
