Actuators - Rotary Actuators

Rotary Actuators come in two types: Rack and Pinion and Vane style. Rack and Pinion rotary actuators are designed to turn heavy loads and provide high torque output. Vane style rotary actuators are ideal for applications that require rotational motion less than one revolution. They 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.

Rack and Pinion

A rack-and-pinion type pneumatic rotary actuator is a rotary actuator used for turning, opening, closing, mixing, oscillating, positioning, and many more mechanical functions involving restricted rotation. It is also often used for automation of quarter-turn or half-turn motion mechanisms. The actuator works in conjunction with a cylindrical piston which is connected to a gear called a rack. From the moment the actuator starts working, the output shaft, piston and rack gear start working together in a linear motion. Rack-and-pinion pneumatic rotary actuators are available in a variety of styles and sizes providing double output torque. They are durable and offer simple installation and high force for their size. SMC offers rack-and-pinion actuators with both shaft and table connections, with rotational arc lengths of 90°, 180°, 190°, or even 270°, depending on the configuration.
