SMC Corporation MSZB20A Pneumatic Rotary Actuator

SMC MSZB20A is a 20 mm bore, 3-position rotary actuator (MSZ series) that delivers precise rotary indexing over a 0 to 190-degree arc. It provides up to 2 Nm of torque and is rated for a maximum operating pressure of 1 MPa. As a basic rotary table, MSZB20A is actuated by an external 3-position, 5-port valve to select left, center, or right stop positions within its 190° travel, enabling deterministic positioning in automated systems. With a compact 20-size body, it is commonly used for pneumatic indexing, part alignment, and positioning tasks in automated equipment, assembly lines, and packaging systems where compact rotary actuation is required.
