Airtac TN Double Axis Double Rod Cylinder TN20X85S
The AirTAC Airtac TN Double Axis Double Rod Cylinder TN20X85S 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 TN20X85S
The TN20X85S is a double-acting twin-rod cylinder whose two parallel rods carry a single shared plate. Because the plate rides on both rods, it resists rotation, bending and twisting, so the load can be mounted directly on it. The 20 mm bore with an 85 mm stroke gives a theoretical push thrust of 314.2 N at 0.5 MPa, and the external front bumper cushions impact while adjusting the effective stroke over -5 to 0 mm.
This is a genuine AirTAC part meeting the ENTERPRISE-standard TN series, with PT threaded ports only. The magnet comes as standard on the whole series, with magnetic-switch slots around the body, and this bore runs at 0.15-1.0 MPa (22-145 psi). Overall dimensions change with the stroke, so contact us and we will confirm dimensions and sizing 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
Match the bore to your thrust: this 20 mm bore provides 314.2 N of theoretical push at 0.5 MPa, with the pull side lower than the push side. TN is the ENTERPRISE-standard twin-rod series limited to PT ports; the JIS-standard TR series is the alternative if you want G or NPT threads or TR's precise guide with higher non-rotating accuracy, low rod-end deflection and two groups of ports on both sides. The 85 mm stroke is selected from this bore's stroke table. Be cautious with strokes that are long relative to the bore: route any long-stroke or side-load case to us for confirmation from the datasheet.
Applications
Assembly station stopper
The plate rises between conveyor product stops to halt parts at an assembly station and hold them square, with the twin rods keeping the plate from twisting as it stops the load.
Eject and discharge pusher
At the discharge end of a machine, the cylinder pushes finished parts off a nest or fixture into a bin or the next conveyor, maintaining a flat, non-rotating push face.
Wide clamp actuator
Where a single rod would cantilever, the twin rods carry a wide clamping plate that presses lids, covers or panels down evenly on a packing or testing fixture.
FAQ
What thrust does the TN20X85S produce at 0.5 MPa?
At 0.5 MPa the 20 mm bore gives a theoretical push thrust of 314.2 N. The pull side is lower than the push side, so check your return-force requirement too; operating pressure for this bore is 0.15-1.0 MPa (22-145 psi).
Is the magnet on the TN20X85S an add-on I need to order separately?
No. The entire TN series is supplied with the magnet fitted as standard, so there is no non-magnetic option to choose. Magnetic-switch slots are machined around the body for direct switch mounting; compatible switch part numbers are listed in the AirTAC catalogue.
