High output force

Rotary Cylinder: Basic Parameters for Selection

A rotary cylinder is a pneumatic actuator that converts the pressure energy of compressed air into the rotary or oscillating motion of an output shaft.

Unlike standard linear cylinders—which only perform linear extension and retraction—this type of cylinder produces rotary output.

It is commonly used in automation equipment for tasks requiring actions such as rotating through an angle, flipping over, or clamping followed by tightening.

Rotary Cylinder: Frequently Asked Questions

MYFEQD offers a comprehensive range of Rotary Cylinder solutions.

Our pneumatic actuators comply with the technical standards of major global brands,

providing quick solutions for model selection across various industrial

pneumatic systems.

Model Selection & Technical Usage FAQ
Can it rotate continuously 360°?

No, only swing within preset angle. Choose air motor for endless rotation.

Equipped with adjustable stopper for fine angle tuning.

Yes, install flow control valve to adjust swing speed.

Overload torque, unclean compressed air, impact without buffer.

Not recommended. Extra support structure needed for heavy radial load.

Calculate load torque from workpiece weight & rotation radius, add safety margin (1.5~2 times).

Suitable for intermittent automation cycle; continuous high-frequency operation needs derating.

NBR nitrile rubber, for general air environment.

FAQ Before Placing a Preliminary Order
Can we customize the rotation angle?

Non-standard swing angle available, please send your requirement for quotation.

Positioning error increases, internal parts wear rapidly, even cause permanent damage.

Can be installed horizontally, vertically or upside down, keep load within specification.

Yes, use synchronous air circuit or proportional valve for synchronization control.

Align shaft concentricity, avoid forced assembly, reserve buffer space.

Double vane delivers higher torque within same size; single vane has larger swing angle range.

Heavy dust will accelerate seal wear, protective cover is recommended.

Pick rack-pinion for high precision; choose vane if compact dimension is priority.
