Airtac TN Double Axis Double Rod Cylinder TN20X25S
The AirTAC Airtac TN Double Axis Double Rod Cylinder TN20X25S 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 TN20X25S
The AirTAC TN20X25S is a double-acting twin-rod cylinder with a 20 mm bore and a 25 mm stroke. Two parallel rods share one plate, giving the body resistance to bending and twisting so the load mounts without rotating. At 0.5 MPa the push-side thrust is 314.2 N; the bumper pad on the front both cushions impact and trims the effective stroke across a -5 to 0 mm range.
This is a genuine AirTAC TN-series part built to the enterprise standard with PT thread ports. The magnet is standard on every model, and magnetic-switch slots run around the body. 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
Choose this 20 mm bore when you need about 314 N of push thrust at 0.5 MPa. The TN series follows the enterprise standard and offers PT thread only; if you need G or NPT threads or higher non-rotating precision, the TR series is the alternative. Keep the 25 mm stroke within the bore's rated table and avoid over-long strokes that increase rod-end deflection beyond the short-cover design capacity. We help confirm the allowable side load from the datasheet curves.
Applications
Product Push-Off Station
Pushes items off a conveyor belt at the end of a packaging line. The twin rods keep the pusher plate flat and prevent rotation so each item is deflected squarely to the divert chute.
Clamp and Hold Fixture
Holds a workpiece flat against a machining fixture. Two parallel rods resist the bending moment from the clamping load and keep the clamp face from twisting during the cut.
Short-Travel Lift Stop
Raises a small pallet stop pin 25 mm to halt a passing pallet on a transfer line, then retracts flush. Anti-rotation keeps the pin vertical each cycle.
FAQ
How does the TN series differ from the TR series?
The TN series follows the enterprise standard and offers PT thread ports only. The TR series follows the JIS standard, offers PT, G, and NPT threads, and adds a lengthening sliding guide for higher non-rotating precision and lower rod-end deflection, with two groups of ports on both sides.
Does the bumper replace an air cushion?
Yes. Both TN and TR use an external bumper pad on the front that cushions impact and adjusts the effective stroke over a -5 to 0 mm range. There is no air cushion on these twin-rod cylinders.
