Airtac TN Double Axis Double Rod Cylinder TN20X170S
The AirTAC Airtac TN Double Axis Double Rod Cylinder TN20X170S is a genuine TN twin-rod (double-rod) double-acting cylinder, 20 mm bore. Two parallel rods on one plate resist bending and twisting and let the load mount without rotating. It delivers about 314.2 N of push at 0.5 MPa. A front bumper cushions the impact and adjusts the stroke over a -5 to 0 mm range.

About the Airtac TN Double Axis Double Rod Cylinder TN20X170S
The TN20X170S is a double-acting twin-rod cylinder with two parallel rods on one shared plate, so the plate resists bending and twisting and your load mounts without rotating. With a 20 mm bore and a 170 mm stroke, it delivers a theoretical push thrust of about 314.2 N at 0.5 MPa - enough for medium-duty pushers, clamps and transfer plates. The external front bumper cushions impact and lets you trim the effective stroke over -5 to 0 mm, so you can fine-tune the end position without shims.
This is a genuine AirTAC part from the ENTERPRISE-standard TN series, fitted with a magnet as standard and magnetic-switch slots around the body for position sensing. It operates on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, temperature -20 to 70 C. Dimensions for this stroke and sizing help are confirmed from the datasheet on request.

Specifications follow the official AirTAC TN/TR twin-rod data. Operating pressure is set by bore (0.2 MPa minimum on the 6 and 10 mm bores). The front cover and piston are short, so avoid an over-long stroke. Overall dimensions vary per stroke and allowable side-load is published as curves — ask us and we confirm from the datasheet.
How to choose
Choose the bore for thrust: at 0.5 MPa this 20 mm bore gives about 314.2 N on the push side (the pull side is lower), so step up to bore 25 or 32 if you need more force, or down to 16 for lighter loads. The TN series is the ENTERPRISE standard with PT threads only; if you need higher non-rotating precision, a lengthening sliding-support guide, or G/NPT ports, look at the TR series instead. Stroke 170 mm sits within the bore 20 table - avoid strokes well beyond the table, as over-long twin-rod strokes can uncover the short cover. Side-load capacity is published as curves, so confirm it with us before sizing marginal loads.
Applications
Lateral pusher on a packaging line
Mount the product plate directly to the twin-rod plate and push cartons sideways into a lane. The two rods keep the plate square, so the carton does not rotate or skew as it travels the 170 mm stroke.
Clamp fixture for machined parts
Use the plate as a wide clamp pad on a drilling or assembly fixture. Twin rods resist the twisting reaction of the clamp force, and the adjustable bumper lets you cushion the clamp's contact with the part.
Stopper gate on a roller conveyor
Raise and lower a stop blade between rollers to release parts one at a time. The shared plate keeps the blade level without extra guides, and the magnet feeds a sensor to confirm the stop position.
FAQ
What does the code TN20X170S mean?
TN is the ENTERPRISE-standard twin-rod series (PT thread only), 20 is the bore in mm, 170 is the stroke in mm, and S confirms the magnet is fitted. Magnet is standard on the whole series - there is no non-magnetic version to choose between.
Do I need external guides to stop the load rotating?
Usually no. The two parallel rods share one plate, which resists bending and twisting, so most pusher, clamp and stopper loads mount straight to the plate. For off-center or side-loaded applications, confirm the allowable side-load curves with us or from the datasheet before relying on the cylinder alone.
