Airtac TN Double Axis Double Rod Cylinder TN25X70S
The AirTAC Airtac TN Double Axis Double Rod Cylinder TN25X70S is a genuine TN twin-rod (double-rod) double-acting cylinder, 25 mm bore. Two parallel rods on one plate resist bending and twisting and let the load mount without rotating. It delivers about 490.9 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 TN25X70S
A twin-rod double-acting cylinder runs two parallel rods on a shared plate, giving the load resistance to bending and twisting so it advances and retracts without rotating. The AirTAC TN25X70-S combines a 25 mm bore with a 70 mm stroke; at 0.5 MPa the theoretical push thrust is roughly 491 N, with push thrust higher than pull. A front bumper pad cushions impact and trims the stroke over a -5 to 0 mm range.
This is a genuine AirTAC part built to the enterprise standard. A magnet is standard on every TN unit, with sensing slots around the body for switch mounting. We confirm dimensions, materials, and allowable side-load curves 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
Thrust scales with bore: the 25 mm bore provides roughly 491 N theoretical push at 0.5 MPa, push exceeding pull. TN follows the enterprise standard with PT threads only; the TR line adds JIS mounting, a precise lengthening guide, and ports on both sides for higher non-rotating accuracy. Select the 70 mm stroke from the bore's table - because TN uses a short cover, be cautious with over-long strokes that increase rod deflection and side load. We confirm side-load and deflection data from the datasheet on request.
Applications
Push-off diverter on a belt line
Mounts at the side of a conveyor to push cartons or trays onto a branch lane; the twin rods keep the pusher plate from tilting so every divert lands squarely.
Clamp hold-down for a machining fixture
Holds a workpiece flat against a locater pin during drilling or milling; the anti-rotation rods stop the clamp arm from twisting under vibration.
Stop-and-release gate at a pick station
Raises a stopper pin to hold totes at an operator's station, then retracts to release them; the guided twin rods keep the pin aligned with the tote pocket.
FAQ
What thread and port size does the TN25X70-S use?
The TN series uses PT threads only; TR is the line that offers PT, G, or NPT. Bore 25 carries an M5x0.8 port. We confirm thread and port details from the datasheet on request.
Why use a twin-rod cylinder instead of a single-rod one?
Two parallel rods on a shared plate resist bending and twisting, letting the load move without rotating - ideal for pushers, clamps, and stoppers where a single rod would let the tooling tilt. We confirm dimensions and allowable side-load from the datasheet on request.
