Linear actuators (screws, nuts, electric actuators)

Linear actuators (screws, nuts, electric actuators) include mechanical and electromechanical components designed to convert rotary motion into linear displacement. The category covers basic design principles based on screw drives and complete electric actuators.

Screws and nuts form a mechanical transmission where the relative motion between the screw thread and the nut generates linear movement. This solution is used for precise positioning and provides repeatability of motion depending on the design implementation.

Electric linear actuators combine an electric motor with a mechanical transmission into compact units; such assemblies allow controlled linear displacement and integration into control systems without a separate external drive.
