Airtac TN Double Axis Double Rod Cylinder TN20X40S
The AirTAC Airtac TN Double Axis Double Rod Cylinder TN20X40S 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 TN20X40S
The TN20X40S is a double-acting twin-rod cylinder: two parallel rods on one shared plate guide the load without rotating, giving resistance to bending and twisting in push, clamp and transfer motions. At 20 mm bore and 40 mm stroke it produces 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 built to the TN enterprise standard with PT ports and a position magnet fitted as standard, plus magnetic-switch slots around the body. It runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), -20 to 70 C, and 30-500 mm/s. Overall dimensions depend on the stroke, so confirm final 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
Choose the bore for the thrust you need: this 20 mm bore gives 314.2 N push at 0.5 MPa (pull side is lower), while 25 and 32 mm bores raise the force and 10 or 16 mm suit compact stations. TN is the enterprise-standard twin-rod series with PT ports only; pick the TR series for the JIS standard's higher non-rotating accuracy, G or NPT threads, or ports on both sides of the body. The 40 mm stroke sits within the bore's stroke table, and over-long strokes should be treated with caution against rod deflection. Route side-load questions to us or the datasheet.
Applications
Machine-tool part ejector
Ejects finished parts from a jig or nest after a machining cycle. The twin rods hold the ejector plate parallel so the part is pushed straight, and the bumper softens the return-side impact.
Tray transfer station
Transfers trays or PCB carriers between two conveyor lanes. Because the plate mounts the load without rotating, the tray arrives square at the next station without external guides.
Light press and clamp
Applies a straight-line press or clamp force in assembly fixtures. With 314.2 N push at 0.5 MPa from the 20 mm bore, it suits light staking, seating and hold-down jobs.
FAQ
Should I choose TN20X40S or a TR twin-rod cylinder?
TN20X40S is the enterprise-standard TN series with PT ports only. The TR series follows the JIS standard and adds higher non-rotating precision, low rod-end deflection, a lengthening sliding-support guide that needs no added lubricant, two groups of ports on both sides, and a choice of PT, G or NPT threads. Choose TR when guide precision or thread options matter.
What does the front bumper on the TN20X40S do?
It is an external bumper pad, not an air cushion. It cushions impact at the end of travel and at the same time adjusts the effective stroke over -5 to 0 mm, letting you trim the plate position without changing the cylinder.
