Airtac TN Double Axis Double Rod Cylinder TN20X50S
The AirTAC Airtac TN Double Axis Double Rod Cylinder TN20X50S 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 TN20X50S
The TN20X50S is a double-acting twin-rod cylinder whose two parallel rods share one plate, so the load mounts without rotating and the plate resists bending and twist. With a 20 mm bore and 50 mm stroke it delivers about 314.2 N of push thrust at 0.5 MPa (pull side is lower), making it a fit for mid-range push, clamp and transfer duties. The external front bumper cushions impact and also adjusts the effective stroke over -5 to 0 mm.
This is a genuine AirTAC part built to the TN enterprise standard, PT thread only, with the magnet fitted as standard and magnetic-switch slots around the body. It uses embedded fixed mounting with three-side plate holes and multi-face body holes, and operates 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 gives 314.2 N of push thrust at 0.5 MPa (pull side lower), so size the bore to your force requirement rather than to the stroke. The TN is the enterprise-standard twin rod with PT threads only; for G or NPT ports, or the JIS guide grade with higher non-rotating accuracy, low rod-end deflection and ports on both sides, choose the TR series. Stroke options come from the bore 20 table, and long strokes should be checked against the short-cover caution - route your stroke and side-load questions to us for confirmation against the datasheet.
Applications
Assembly-line part pusher
Positions or pushes housings into a nest at a manual or automated station; the twin-rod plate gives a stable, non-rotating pushing face, and the bumper absorbs the end-of-stroke impact.
Press-fit assist station
Applies a light pressing action to seat plugs or bearings in plastic housings; at 0.5 MPa the bore 20 twin rods supply about 314.2 N of push, and the bumper limits the shock at full compression.
Tote diverting on sortation conveyors
Kicks totes off a sortation lane onto a takeaway spur; the shared plate keeps the pusher paddle square to the tote through the 50 mm stroke without rotating under off-centre contact.
FAQ
What operating pressure and thrust should I design the TN20X50S around?
This bore 20 model runs at 0.15-1.0 MPa (22-145 psi). At 0.5 MPa the theoretical push thrust is 314.2 N, with the pull side lower because the rods reduce the pull area. Confirm the exact force you need at your working pressure before selecting the bore.
Can the bumper replace an air cushion on this cylinder?
The TN20X50S uses an external front bumper rather than an air cushion. It both cushions the impact at end of travel and adjusts the effective stroke over -5 to 0 mm. Full dimensions and mounting details for your layout are confirmed from the datasheet on request.
