Rotary Actuators

What are Rotary Actuators?
Pneumatic rotary actuators are a device that produces a rotary motion via a shaft to control the speed and rotation of attached equipment.
How do they work?
Compressed air is connected into the pneumatic connection on the rotary actuator which drives a cylinder stroke into an oscillating rotary motion. Rotary actuators have the potential to improve and simplify applications that typically use pneumatic cylinders because they are self-contained and support loads due to the internal bearing sets.
Where would you use on?
Rotary actuators are commonly used in industrial applications such as conveying, clamping, transferring parts, positioning, and controlling valves. Like other pneumatic components, they are durable, offer simplicity and high force for their size, and can operate in hazardous environments.
