SMC manufactures both Rack and Pinion and Vane style pneumatic rotary actuator products. Combination rotary models combine compact linear cylinders and rotational capability. Combinations are also available that include rotary gripper capabilities. When the application calls for rotational motion less than one revolution, rotary cylinders can mount right at the equipment joint without taking up space with long stroke lengths, which would be required to do the same job with a linear cylinder. SMC’s pneumatic rotary actuator units can achieve arc lengths of 90°, 180°, 190°, or even 270°, depending on the configuration. SMC offers both electric and pneumatic rotary actuator products.
