Airtac TN Double Axis Double Rod Cylinder TN20X40SH
The AirTAC Airtac TN Double Axis Double Rod Cylinder TN20X40SH 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 TN20X40SH
The TN20X40SH is a double-acting twin-rod cylinder: two parallel rods on one shared plate carry the load without rotating, resisting bending and twisting in push, clamp and stopper applications. At 20 mm bore and 40 mm stroke it gives a theoretical push thrust of 314.2 N at 0.5 MPa, while the external front bumper cushions impact and adjusts the effective stroke over -5 to 0 mm.
This is a genuine AirTAC part built to the TN enterprise standard with a position magnet fitted as standard and magnetic-switch slots around the body. It operates on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), -20 to 70 C, and 30-500 mm/s. The trailing H is not part of the standard TN20X40S decode, so confirm the exact variant, thread and dimensions from the datasheet or with us 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
Bore sets the force: this 20 mm bore provides 314.2 N push at 0.5 MPa (the pull side is lower), with 25 and 32 mm bores for heavier duty and 10 or 16 mm for tighter spaces. TN is the enterprise-standard twin-rod series, PT ported as a series; G and NPT threads are only available on the JIS-standard TR series, which also adds higher non-rotating precision and two groups of ports on both sides. The 40 mm stroke is within the bore's stroke table, and over-long strokes should be treated with caution against rod deflection. Confirm the H suffix, side-load capability and final dimensions from the datasheet or with us.
Applications
Indexing-table stopper
Stops and holds a rotary indexing table at each station. The twin rods keep the stop plate from rotating, and the adjustable bumper absorbs the table's arrival impact.
Assembly-station clamp
Clamps brackets or housings during screwdriving and welding. With 314.2 N push at 0.5 MPa from the 20 mm bore, the flat twin-rod plate holds parts square without twisting.
Vertical lift module
Lifts small pallets or fixtures in a compact lifting module. The two parallel rods share the bending load, keeping the mounting plate level through the 40 mm stroke.
FAQ
What does the H suffix in TN20X40SH mean, and which thread does it use?
The TN series is a PT-port series, so G and NPT threads are not offered on it. The trailing H is not part of the standard TN20X40S decode, so confirm the exact variant and its port detail from the datasheet or with us before ordering.
How much thrust does the TN20X40SH produce, and how is the stroke trimmed?
At 0.5 MPa the 20 mm bore gives a theoretical push thrust of 314.2 N, with the pull side lower. The external bumper is not an air cushion: it cushions impact and adjusts the effective stroke over -5 to 0 mm, so you can shorten the travel slightly at setup.
