Pneumatic rotary cylinder, also called pneumatic rotary actuator. It is an actuator of a device that converts energy into mechanical motion,which uses compressed air to push the rack and pinion inside, thereby turning linear motion into rotary motion.
Rotary pneumatic actuators are generally designed for use in many motion control systems to operate, for example, pick and place handlers or grippers, or to remotely control valves.
Air rotary cylinder is a special type of air operated pneumatic actuator. The kind of rotary air cylinder that uses compressed air to actuate load rotary motion instead of linear motion. It is widely used in automated equipment that requires Fixed-angle rotation, adjustable-angle rotation, and even continuous rotational action, such as material turning, mechanical grippers, sorting arms, and rotary tables.
A rotary actuator that converts compressed air pressure into rotational motion, commonly used in machinery to achieve rotational functions.It has many features as follows:
Built-in Magnetic Ring: Equipped with an internal magnetic ring, allowing compatibility with magnetic switches for position detection.
Angle Adjustable: The rotation angle is adjustable, offering flexibility for a wide range of operational requirements.
Design Feature: The design is engineered for efficiency and ease of use, ensuring optimal performance and straightforward installation.
Aluminum Alloy Construction: The cylinder is made of durable aluminum alloy, which is resistant to corrosion, able to operate in both high and low temperature environments, and provides strong resistance to moisture and water ingress.
Large Output Force: The cylinder delivers a significant output force, making it suitable for tasks requiring substantial torque and power.
Rotary Motion:Converts the energy of compressed air into controllable rotary torque, actuating rotary motion with adjustable rotation angles.
Precise Positioning and Rotation:Capable of achieving precise angular positioning or repeated rotation in mechanical applications, such as robotic arm joints, fixture rotation, and valve actuation.
Alternative to Electric or Hydraulic Rotary Devices:Ideal for applications that require fast response, simple structure, and lower cost—serving as an efficient alternative to electric or hydraulic rotary actuators.
High Reliability and Durability:Provides consistent and stable rotary output even under harsh operating conditions.
As a special type of pneumatic cylinder that actuate rotary motion, the rotating pneumatic cylinder features a compact structural design as one of its key highlights. In addition, rotary cylinders offer several other advantages.
Simple Structure, Low Cost:Compared to electric servo motors or hydraulic systems, rotary air cylinders have a simpler structure, lower cost, and are easier to maintain.
Fast Response:Pneumatic systems respond quickly, making them ideal for automation scenarios requiring high-speed switching and rapid rotation.
Stable Torque Output:They can deliver a relatively high torque in a short time, meeting the needs of many light- to medium-load rotational applications.
Flexible Control:Precise control can be achieved through pneumatic valves or solenoid valves, and they can also be integrated with sensors for position feedback control.
Multiple Rotation Angles Available：
Fixed angles (90° / 180° / 270°)
Adjustable angles (e.g., 0°–190°)
Continuous rotation (in certain special models)
Compact Size, High Adaptability:Compact design makes them suitable for space-constrained environments and easy to integrate into various automation systems.
A pneumatic rotating actuator operates by using air pressure to move a piston or diaphragm within one or more air chambers, creating rotational motion.
In some designs, the rotary cylinder actuator initially generates linear motion, which is then converted internally into rotary motion.
This conversion typically occurs through mechanisms such as pivot arms or bearings.
The actuator's air pressure-driven motion is highly efficient, providing substantial force relative to its compact size.
Air actuator cylinders are self-contained systems, meaning their internal components are protected from contaminants and harsh environments, resulting in reduced wear and longer service life.
They are commonly used to drive rotary valves, but their design can also simplify systems that require torque generation, making them a reliable and low-maintenance solution for various industrial applications.
Pneumatic rotary actuators are widely used in industrial applications that require precise rotary positioning, such as automation systems, fixture mechanisms, valve control, and workpiece flipping.
Used for rotating valves, gates, and dampers in manufacturing and processing systems.
Employed in automated systems for rotating or positioning components, such as conveyors and robotic arms.
Used in clamping devices for secure positioning in assembly and machining processes.
Applied in the rotation of bottles, lids, labels, and other packaging tasks.
Fescolo supply pneumatic rotary cylinder types are with pinion and rack structure, actuating smoothly, and the interior is a double-cylinder structure, which can achieve double the output force. A rotary cylinder has high machining accuracy, convenient load installation and accurate positioning. There are installation holes in the middle of the worktable, which is convenient for installation and use.
Common pneumatic rotary cylinders have MSQ, CRQ2, CRA1 series. According to the buffer type, it can be divided into adjustment screw fixed buffer and hydraulic buffer. The maximum buffer energy of hydraulic buffer is 3 to 5 times that of the adjustable screw fixed buffer, and the buffer effect is much better than adjustable screw buffer.
According to the rotating angle, it can be divided into 180 degree rotary actuator and 90 degree rotary actuator.
◆ When use rotary cylinder in low temperature environments, you need to take antifreeze measures.
◆ Before using rotary actuators, please remove the debris inside.
◆ If a actuator is not used for a long time, it is necessary to pay attention to the anti-rust care of the surface, and apply anti-rust oil to the moving parts. Dust plugs should be added to the air inlet and outlet.
The following influencing factors need to be considered when using the rotary actuator：
◆ Working pressure: 0.10~0.70MPa
◆ Proof pressure: 1.50MPa
◆ Ambient temperature: 0~60℃
◆ Structure: Pinion and rack
◆ Applicable fluid medium: Filtered compressed air
◆ Rotating angle range: 0~190°
◆ Cushion types: Fixed screw cushion and Hydraulic buffer
