TN25×20 Twin-Rod Pneumatic Cylinder – 25mm Bore × 20mm Stroke – Double Acting
The TN25×20 Twin-Rod Pneumatic Cylinder is a compact double-acting pneumatic actuator designed for accurate, stable and repeatable linear movement in industrial automation, packaging machinery, positioning systems, clamping equipment and compact production machinery.
Featuring a 25 mm bore and 20 mm stroke, the TN25×20 uses two Ø12 mm guide rods to provide high rigidity and improved resistance to rotation. The twin-rod configuration helps maintain accurate alignment of the moving plate, making it suitable for short-stroke applications requiring controlled linear motion and good load stability.
The cylinder operates using compressed air for both extension and retraction, providing positive movement in both directions.

Double-Acting Operation
The TN25×20 uses two pneumatic ports. Compressed air supplied to one side causes the actuator to extend, while air supplied to the opposite side causes it to retract.
A suitable pneumatic directional or solenoid valve can be used to control movement. Flow-control fittings may also be installed to regulate speed.
Installation Notes
Use clean, filtered compressed air and correctly sized pneumatic fittings and tubing. Ensure the actuator is aligned with the moving load and avoid unnecessary side loading.
