Airtac TN Double Axis Double Rod Cylinder TN25X85S
The AirTAC Airtac TN Double Axis Double Rod Cylinder TN25X85S 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 TN25X85S
The AirTAC TN25X85S is a double-acting twin-rod cylinder with a 25 mm bore and an 85 mm stroke. The shared twin-rod plate resists bending and twisting so the mounted load travels in a straight line without rotation. At 0.5 MPa the push thrust is 490.9 N (pull is lower), and the external bumper absorbs impact while offering a -5 to 0 mm stroke trim.
This is a genuine AirTAC part manufactured to the enterprise standard. Each unit includes a standard magnet with sensor slots around the cylinder body. We verify 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
The 25 mm bore provides 490.9 N push thrust at 0.5 MPa; match the bore to your force need, then pick the stroke from the bore's published table. TN is the enterprise-standard twin-rod with PT thread only; for JIS fitment, greater non-rotating accuracy, a lengthening sliding guide, or G/NPT thread choices, the TR series is the alternative. Keep strokes within the bore's rated range given the short-cover design; contact us to confirm side-load limits for your setup.
Applications
Vertical Lift Gate
Raises and lowers a gate plate between pass and block positions; the twin rods keep the gate horizontal and resist the torque from an off-centre load.
Reject Pusher
Kicks a non-conforming part off a conveyor belt; the dual rods keep the pusher face square so the part exits cleanly without catching on the guide rail.
Indexing Stop
Positions a stop finger to set the workpiece against a machining fixture; the rods prevent finger rotation under cutting vibration and repeated cycling.
FAQ
What does the S in TN25X85S mean, and is the thread PT?
The S indicates the standard magnet, which is fitted on every TN-series unit. TN cylinders ship with PT thread only; if you need G or NPT thread, the TR series offers those options.
Can the twin rods replace a separate guide for high side loads?
The twin rods do resist bending and twisting, which helps prevent load rotation, but allowable side-load depends on the bore and stroke and is published as curves. We confirm the specific side-load and envelope dimensions for your mounting from the datasheet.
