Airtac TN Double Axis Double Rod Cylinder TN20X45S
The AirTAC Airtac TN Double Axis Double Rod Cylinder TN20X45S 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 TN20X45S
The TN20X45S is a double-acting twin-rod cylinder: two parallel rods share one plate, so the load mounts without rotating and the plate resists bending and twist. This 20 mm bore, 45 mm stroke version gives about 314.2 N of push thrust at 0.5 MPa (pull side is lower), suiting short-reach push, clamp and stop stations. An external bumper on the front both cushions impact and trims the effective stroke over -5 to 0 mm.
This is a genuine AirTAC part built to the TN enterprise standard, PT threaded only, with a magnet fitted as standard and magnetic-switch slots around the body. It mounts embedded, with three-side holes on the plate and multi-face holes on the body, and runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), -20 to 70 C, 30-500 mm/s. 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
Bore 20 delivers 314.2 N of push thrust at 0.5 MPa (pull side lower), so step up or down a bore if your force budget differs. TN is the enterprise-standard twin rod; choose TR instead if you need the JIS guide grade with higher non-rotating accuracy, low rod-end deflection and ports on both sides. Note that TN is PT thread only. Strokes come from the bore 20 table, and long strokes should be checked against the short-cover caution - confirm with us. Side-load figures are published as curves, so route your fixture loads to us for confirmation.
Applications
Conveyor line stopper
Mounted at the conveyor edge, the twin rods keep the stopper blade square to the flow, indexing cartons or totes to a fixed stop plate without rotating under repeated pushes.
Fixture clamping
Clamps workpieces in drill and assembly jigs: the shared plate spreads the clamp force evenly, the twin rods hold the jaw aligned, and the bumper eases the clamp onto the part.
Push-and-eject station
Ejects finished parts off a line into a chute or bin; with 314.2 N of push at 0.5 MPa this 20 mm bore handles lightweight assemblies, and the bumper softens the end of each stroke.
FAQ
Is the magnet optional on the TN20X45S?
No. Every TN-series cylinder, including the TN20X45S, is supplied with a magnet fitted as standard, and magnetic-switch slots run around the body. There is no non-magnetic version to choose between.
How does the stroke adjustment and cushioning work?
The external front bumper both cushions impact at the end of travel and adjusts the effective stroke over -5 to 0 mm; it is a pad, not an air cushion. Exact mounting dimensions and side-load limits for your fixture are confirmed from the datasheet on request.
