Airtac TN Double Axis Double Rod Cylinder TN20X55S
The AirTAC Airtac TN Double Axis Double Rod Cylinder TN20X55S 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 TN20X55S
A twin-rod double-acting cylinder places two parallel rods on a shared plate so the load travels without rotating and resists bending and twisting. This 20mm bore, 55mm stroke model produces a theoretical push thrust of 314.2 N at 0.5 MPa. An external bumper cushions end-of-stroke impact and adjusts the effective stroke over a -5 to 0 mm range.
This is a genuine AirTAC TN-series cylinder built to the enterprise standard with PT threading. A magnet is fitted as standard, with magnetic-switch slots around the body. We 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
Bore 20mm gives a theoretical push thrust of 314.2 N at 0.5 MPa; pull is lower. TN is the enterprise standard with PT thread only. If you need JIS standard, G or NPT threads, or a precise lengthening guide for higher non-rotating accuracy, consider the TR series. Choose the 55mm stroke within the bore 20 stroke table, and avoid over-long strokes on the short-cover design. We help confirm allowable side-load from the datasheet.
Applications
Transfer Pusher
Transfers cartons between two conveyors; the twin rods keep the push face parallel so cartons feed squarely onto the receiving belt.
Press Clamp
Clamps a sheet-metal panel for a forming press; the anti-rotation twin rods hold the clamp flat so the panel does not shift during pressing.
Pallet Stop
Halts pallets at a packing station; twin rods resist the side load of an incoming pallet so the stop block stays aligned and repeatable.
FAQ
What is the difference between TN and TR twin-rod cylinders?
TN is the enterprise standard with PT thread only. TR is the JIS standard with PT, G, or NPT thread options and a precise lengthening guide for higher non-rotating accuracy. Both are magnet-fitted as standard.
How does the twin-rod design prevent rotation?
Two parallel rods on a shared plate resist bending and twisting so the load mounts and moves without rotating. We confirm allowable side-load from the datasheet for your application.
