The SMC Rotary Actuator is a type of actuator with a composite rotary model combining compact linear cylinders and rotational capabilities. Combinations are also available which include the ability of the rotary gripper. When the Solenoid Actuator application for rotational motion is less than one revolution, the rotary cylinder can mount right on the joint equipment without taking up space with a long stroke length, which will be needed to do the same work with a linear cylinder. Pneumatic SMC rotary actuator units can reach arc lengths of 90 °, 180 °, 190 °, or even 270 °, depending on configuration. SMC offers electric and pneumatic rotary actuator products.
