TN series twin rod pneumatic cylinder is a compact double-acting pneumatic actuator with two parallel piston rods. Unlike standard single-rod cylinders, its integrated dual-rod design delivers double thrust and built-in anti-rotation performance without extra external guides. The optional built-in magnet supports magnetic switches for stroke position detection. Widely used for clamping, positioning, pick-and-place and material handling in automated machinery, packaging equipment and 3C automation lines.

A major advantage of a double-rod cylinder is its ability to maintain the orientation of the moving load. The two rods work together to reduce rotation during linear movement.
The dual-rod structure distributes the load more evenly, which can improve the stability of the moving mechanism.
For automated machinery with limited installation space, a compact twin-rod cylinder can provide stable movement without requiring a large external guiding mechanism.
The TN Series is designed for repetitive reciprocating motion, making it suitable for automated production lines operating continuously.
Choosing the correct cylinder depends on the mechanical requirements of the application.
Requirement | Standard Single-Rod Cylinder | TN Double Rod Cylinder |
|---|---|---|
Basic pushing/pulling | ★★★★★ | ★★★★★ |
Compact installation | ★★★★☆ | ★★★★☆ |
Anti-rotation | ★★☆☆☆ | ★★★★★ |
Load stability | ★★★☆☆ | ★★★★★ |
Guided movement | ★★★☆☆ | ★★★★★ |
Repetitive positioning | ★★★★☆ | ★★★★★ |
Lateral-load applications | ★★☆☆☆ | ★★★★☆ |
Choose a TN Series cylinder when the application requires more stable and controlled linear movement.
For applications where the cylinder only needs to provide simple pushing or pulling force, a conventional single-rod cylinder may be sufficient.
Before selecting a TN Series cylinder, several parameters should be confirmed.
The bore diameter determines the theoretical pneumatic force.
Larger bore sizes generally provide greater output force at the same operating pressure.
The stroke should correspond to the required travel distance of the moving mechanism.
For example:
Required movement = 100 mm → Select a cylinder with an appropriate 100 mm stroke.
Consider both the weight of the moving load and any external resistance.
For horizontal applications, friction and acceleration should also be considered.
Confirm the available compressed-air pressure before selecting the cylinder.
Check the cylinder's overall dimensions, port position and mounting configuration to ensure sufficient installation space.
If high-speed reciprocating movement is required, the air supply, flow-control valves, tubing and cushioning configuration should all be considered.
A typical TN Series pneumatic actuator system can include:
Air Compressor → Air Filter → Regulator → Solenoid Valve → Flow Control Valve → TN Cylinder
The air preparation unit removes contaminants and regulates the air pressure, while the solenoid valve controls the cylinder's forward and backward movement.
Flow-control valves can be used to adjust the cylinder's operating speed.
To achieve stable and long-term operation:
Make sure the cylinder is correctly aligned with the driven mechanism.
Avoid excessive lateral loads.
Select the appropriate bore and stroke according to the application.
Use clean and properly regulated compressed air.
Adjust the operating speed using suitable flow-control valves.
Check the mounting screws and connections regularly.
Avoid exceeding the recommended operating pressure and load.
Proper installation can significantly improve the service life and operating stability of the pneumatic actuator.
A TN double rod pneumatic cylinder is a double-acting pneumatic actuator equipped with two piston rods. Its twin-rod structure provides more stable linear movement and better resistance to rotation.
The main advantages include better anti-rotation performance, improved load stability, balanced movement and reliable linear positioning.
Yes. The TN Series is generally used as a double-acting pneumatic cylinder, with compressed air controlling both extension and retraction.
The required bore depends mainly on the load, operating pressure, required force and safety factor. A larger bore provides greater theoretical output force.
It can be used for repetitive automated movement, but the actual achievable speed depends on the cylinder specification, load, operating pressure, tubing, valves and flow-control settings.
