TN20×20 Twin-Rod Pneumatic Cylinder – 20mm Bore × 20mm Stroke – Double Acting
The TN20×20 Twin-Rod Pneumatic Cylinder is a compact double-acting pneumatic actuator designed for precise and stable linear movement in industrial automation, packaging machinery, positioning systems, clamping equipment and compact production machinery.
Featuring a 20 mm bore and 20 mm stroke, the TN20×20 uses two Ø10 mm guide rods to provide increased rigidity and resistance to rotation. The twin-rod configuration helps maintain accurate alignment of the moving plate, making it suitable for applications requiring short, repeatable and controlled linear motion.
Its compact aluminium body and short 20 mm stroke make the TN20×20 particularly suitable where installation space is limited.

Double-Acting Operation
The TN20×20 uses compressed air to control movement in both directions. Air supplied to one pneumatic port causes the actuator to extend, while air supplied to the opposite port causes it to retract.
A suitable pneumatic directional or solenoid valve can be used to control the cylinder. Flow-control fittings may also be installed where movement speed needs to be adjusted.
Theoretical Output Force
At 0.5 MPa, the supplied TN20×20 specification indicates approximately 25 kgf theoretical thrust.
Actual usable force may be lower due to internal friction, operating pressure variation, load alignment and other installation conditions.
Note: Dimensions and specifications above are based on the supplied TN20×20 reference image. Verify critical dimensions on the actual product before fabrication or permanent machine installation.
