The AirTAC Airtac TR Twin-Rod Cylinders TR25X40S is a genuine TR 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. As the JIS guide-grade series it adds high non-rotating precision, a lengthening sliding guide (no added lubricant) and two-side ports.
A twin-rod cylinder uses two parallel rods on one shared plate to resist bending and twisting, so the load moves without rotating. The TR25X40S has a 25mm bore and 40mm stroke; at 0.5 MPa it delivers 490.9 N push thrust, and the adjustable bumper cushions impact over a -5 to 0 mm range.
This is a genuine AirTAC part built to JIS standard with the precise guide-grade design: higher non-rotating accuracy, low rod-end deflection, a lengthening sliding-support guide that needs no added lubricant, and two port groups on both sides. A magnet is standard on every model, and we confirm 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.
For thrust, the 25mm bore gives 490.9 N push at 0.5 MPa. TN is the enterprise standard with PT thread only, while TR is JIS with PT, G, or NPT threads and the precise guide for higher anti-rotation accuracy. A 40mm stroke sits within the bore's standard range; keep stroke reasonable for the cover length to avoid over-travel. We confirm allowable side-load from the datasheet curves on request.
Mounts on a conveyor line to push product from the main belt onto a side chute; the twin rods keep the pusher plate flat so items divert cleanly without skewing.
Holds a workpiece against a machining stop; anti-rotation keeps the clamp face parallel to the part so clamping force stays even across the full contact area.
Shifts a palletized load between two stations on a guide rail; the twin-rod design resists the bending moment from the off-center mass during the traverse.
At 0.5 MPa the 25mm bore gives 490.9 N push thrust (pull side is lower). The full thrust-pressure curve is in the datasheet, which we can confirm on request.
The bumper is an external front pad that cushions impact and lets you trim the effective stroke by -5 to 0 mm. It is not an air cushion; the bumper absorbs the end-of-stroke hit mechanically.
