Airtac TN Double Axis Double Rod Cylinder TN20X20SH
The AirTAC Airtac TN Double Axis Double Rod Cylinder TN20X20SH 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 TN20X20SH
A twin-rod double-acting cylinder uses two parallel rods on a shared plate to resist bending and twisting so the load moves without rotating. This AirTAC TN20 model has a 20 mm bore and 20 mm stroke, delivering a theoretical push thrust of 314.2 N at 0.5 MPa on the higher push side. Impact is absorbed by an external bumper pad that also fine-tunes stroke length across a -5 to 0 mm adjustment range.
This is a genuine AirTAC part built to the enterprise standard with PT thread ports. A magnet is standard on every unit, and magnetic-switch slots are machined around the body. Contact us to confirm dimensions and sizing from the datasheet for your mounting arrangement.

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 the thrust you need: the 20 mm bore gives 314.2 N push at 0.5 MPa (the pull side is lower). TN is the enterprise-standard line with PT thread only; the TR line adds JIS mounting, a lengthening sliding guide for higher non-rotating precision, and a choice of PT, G, or NPT thread. The 20 mm stroke keeps rod-end deflection low, but always confirm side-load limits from the published curves. Ask us to verify your mounting arrangement against the datasheet.
Applications
Short-Stroke Clamp
Clamps a workpiece in a machining fixture with a compact 20 mm stroke; the twin rods keep the clamp jaw parallel and resist the cutting-force torsion that would twist a single-rod cylinder.
Transfer Gate
Moves a diverter gate or flap between two positions on a packaging line; the short stroke and twin-rod guide hold the gate face flat against the product path without rotation.
Pick-and-Place Stop
Acts as a programmable stop or escapement in an assembly cell, extending 20 mm to hold a part then retracting to release it; the rods keep the stop face perpendicular through every cycle.
FAQ
What thrust does the TN20X20SH deliver, and is the magnet optional?
The 20 mm bore produces a theoretical push thrust of 314.2 N at 0.5 MPa; the pull side is lower. A magnet is standard on every unit in the TN and TR series, so there is no non-magnetic option to select. Magnetic-switch slots are machined around the cylinder body for sensor installation.
How does the bumper cushion work on this short-stroke model?
The cylinder uses an external bumper pad, not an air cushion. The bumper absorbs end-of-stroke impact and lets you trim the effective stroke by -5 to 0 mm. Because the 20 mm stroke is short, side-load and deflection stay low, but we still recommend confirming limits from the datasheet curves.
