Airtac TN Double Axis Double Rod Cylinder TN20X30SH
The AirTAC Airtac TN Double Axis Double Rod Cylinder TN20X30SH 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 TN20X30SH
TN20X30SH is a double-acting twin-rod cylinder: two parallel rods move one shared plate that mounts the load without rotating, giving resistance to bending and twisting. The 20 mm bore with 30 mm stroke produces a theoretical push thrust of 314.2 N at 0.5 MPa, well matched to short, repeatable push and clamp motions. An external front bumper cushions the end of stroke and adjusts the effective stroke over -5 to 0 mm, so final position can be trimmed on the machine.
It is a genuine AirTAC part from the TN series, built to the ENTERPRISE standard for twin-rod cylinders, with PT port threads. A magnet is fitted as standard on every unit and magnetic-switch slots run around the body. Operating medium is air filtered to 40 um, media temperature -20 to 70 C, proof pressure 1.5 MPa (215 psi). We confirm exact 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 is chosen for thrust: at 20 mm this model gives 314.2 N theoretical push at 0.5 MPa, with the 16-32 mm bore operating range of 0.15-1.0 MPa (22-145 psi). Stroke 30 mm is one of the standard steps in the 20 mm bore table; keep the selected stroke close to what the application needs rather than oversizing, because the cylinder body lengthens with stroke.
As a TN-series cylinder this model is ENTERPRISE standard and PT-thread only; the TN range offers no G or NPT option. If your circuit needs those threads, or you want TR's precise guide grade with its lengthening sliding-support guide, move to the TR series. For allowable side load on the rods, send us the application details and we will confirm from the published curves.
Applications
Part hold-down on a dial table
Holds a stamped part flat in its nest while a press or punch cycles above. The twin-rod plate presses without rotating so the part orientation is preserved, and the bumper adjusts contact timing over the last 5 mm.
Package divert pusher
Kicks packages from a main conveyor onto a spur. The plate stays square to the carton through the push, and the -5 to 0 mm bumper trim keeps the divert point consistent as belt speed changes.
Tote stop and locate
Stops and locates a tote at a pick station in a small warehouse module. The twin rods resist the twisting the tote applies as it arrives off-center, and the magnet signals the stopped position from the body slots.
FAQ
What port thread does the TN20X30SH use, and can I get NPT?
The whole TN series, including the TN20X30SH, is supplied with PT port threads only. NPT and G ports are not offered on TN; they are available on the TR twin-rod series, which is the JIS-standard counterpart.
How does the bumper work at the end of stroke?
It is an external bumper pad on the front of the cylinder, not an air cushion. It cushions the impact of the plate reaching the end of stroke and can adjust the effective stroke over -5 to 0 mm, letting you fine-tune the stopping position.
