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.
Equipped with an internal magnetic ring, allowing compatibility with magnetic switches for position detection.
The rotation angle is adjustable, offering flexibility for a wide range of operational requirements.
The design is engineered for efficiency and ease of use, ensuring optimal performance and straightforward installation.
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.
The cylinder delivers a significant output force, making it suitable for tasks requiring substantial torque and power.
A pneumatic rotary 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 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.
Pneumatic rotary actuators 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.
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.
Powers rotational movement in robotic arms for various tasks like assembly, inspection, and packaging.
Provides precise rotational motion for accurate positioning in automated systems and CNC machines.
Used in testing rigs, simulation equipment, and angular motion applications.
Employed in testing, simulation, and development applications requiring rotary motion.
Utilized in inspection systems that require rotational movements for precise measurements and analysis.
Fk pneumatic rotary cylinders are with pinion and rack structure, running 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 rotary actuators are 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 pneumatic actuators in low temperature environment, need to take antifreeze measures.
◆ Before using pneumatic rotary actuators, please remove the debris inside
◆ If a pneumatic rotary cylinder 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 cylinder 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
