Numatics MJ3 Pneumatic Cylinder Actuator Unit

The Numatics MJ3 Pneumatic Cylinder Actuator Unit is a compact linear pneumatic actuator that converts filtered compressed air into controlled linear motion for industrial automation and machine control applications. Commonly installed in packaging machinery, conveyors, automated assembly stations, and machine guarding systems, it is well-suited to OEM equipment and retrofit projects where space is limited. The actuator features a machine-mount configuration and a typical aluminum alloy body, designed for rugged manufacturing environments. It operates on filtered compressed air, with a maximum typical operating pressure of up to 150 PSI for Numatics actuators, delivering repeatable linear reciprocating motion. This unit serves as a repair and replacement component in industrial systems and is compatible with pneumatic automation equipment. As a legacy actuator, published specifications are limited, and it is often referenced alongside replacement options such as Numatics NFPA Pneumatic Cylinders and the Emerson ASCO Numatics Pneumatic Actuator Series.
