The SMC 1390806 is a compact single-acting spring-return pneumatic cylinder designed for linear actuation in automated systems. It has a 1" bore and a 1.5" stroke, with air pressure providing the extend motion and a built-in spring driving retraction. This spring-return configuration simplifies circuitry by eliminating the need for continuous air to retract, making it well-suited for short-stroke actuation in fixtures and basic automation tasks.
