Airtac TN Double Axis Double Rod Cylinder TN25X20S
The AirTAC Airtac TN Double Axis Double Rod Cylinder TN25X20S 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 TN25X20S
A twin-rod cylinder uses two parallel rods on a shared plate to resist bending and twisting, so the load travels without rotating. This AirTAC TN25X20S pairs a 25 mm bore with a short 20 mm stroke; at 0.5 MPa the push thrust is 490.9 N. The external bumper cushions impact and adjusts the stroke over a -5 to 0 mm range.
This is a genuine AirTAC part built to the enterprise standard with a standard magnet and magnetic-switch slots around the body. TN cylinders use PT threads only. 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.
How to choose
Choose this 25 mm bore when you need the 490.9 N push at 0.5 MPa that the twin-rod design delivers. The short 20 mm stroke suits compact stops and clamps where travel is small but thrust must stay high. TN is the enterprise-standard series with PT ports only; the TR series adds JIS mounting, higher non-rotating precision, a lengthening sliding guide, and a choice of PT, G, or NPT threads. Confirm allowable side-load with us before ordering.
Applications
Short-Stroke Clamp
Clamps a bracket against a drill jig in a 20 mm travel; the twin rods hold the clamp face parallel under cutting load so the bracket does not lift on one side.
Part Transfer Pusher
Shoves a machined part 20 mm from a fixture onto a downstream rail; the non-rotating rods keep the pusher pad flat against the part for a clean handoff.
Inline Stopper
Extends a stop pin 20 mm into a conveyor lane to halt pallets; the twin rods absorb the pallet's momentum without the pin twisting in its guide.
FAQ
What thread options does the TN25X20S offer?
TN cylinders are PT-thread only. If you need G or NPT threads, the TR series offers all three (PT, G, and NPT) along with JIS mounting and higher non-rotating precision.
How does the adjustable bumper work?
The bumper is an external front pad that cushions impact at end-of-stroke and lets you trim the effective stroke by up to 5 mm (a -5 to 0 mm range). It is not an air cushion; it is a mechanical bumper on both TN and TR models.
