Airtac SAUD Double Rod Cylinder SAUD80X290S
The AirTAC SAUD Double Rod Cylinder SAUD80X290S is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 290mm stroke, 3/8" air ports and adjustable end cushioning. Its hard-anodized aluminum-profile barrel is shorter than an ISO 15552 cylinder of the same bore, and it shares SC-series mounting accessories.

About the Airtac SAUD Double Rod Cylinder SAUD80X290S
The AirTAC SAUD80X290S is a double-acting, double-rod profile cylinder. A 25mm rod protrudes from both ends, meaning push and pull forces are identical at 2268N each way at 0.5MPa. The extruded aluminium barrel is shorter than an ISO 15552 unit of the same bore. This -S variant includes a piston magnet for CMSG, DMSG or EMSG switches.
With a 3/8 inch port and M20x1.5 rod thread, it delivers 3175N at 0.7MPa and 4082N at 0.9MPa. Adjustable 28mm cushions decelerate the piston at stroke ends.

Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2268 N | 2268 N |
| 0.7 MPa | 3175 N | — |
| Max (@1.0 MPa) | 463 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAUD Double Rod Cylinder SAUD80X290S Is Used
Twin-Tool Stamping
Drives two synchronized forming tools from one piston, ensuring parallel contact without rotational twist.
Dual Transfer Arms
Powers opposing pick-and-place arms that move parts simultaneously across a packaging line.
Guided Clamping Jig
Holds workpieces flat using the inherent anti-rotation property of the dual-rod assembly.
Is the Airtac SAUD Double Rod Cylinder SAUD80X290S the Right Cylinder?
Choose this 80mm bore if you need 2268N of equal bidirectional force. Step down to the 63mm bore for 1402N, or up to the 100mm bore for 3681N. A twin-rod design is ideal for anti-rotation guidance, driving twin tools, or mounting a switch cam on the back rod. Mounting fits AirTAC SC series FA and LB brackets. For the 290mm stroke, ensure external load guides are used to prevent side-load binding.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB — same as SC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAUD Double Rod Cylinder SAUD80X290S FAQ
Force is equal both ways due to the double rod. It provides 2268N at 0.5MPa, 3175N at 0.7MPa, and 4082N at 0.9MPa.
No. The cushions only decelerate near stroke ends; they do not lock the piston. Use an external rod lock or pilot-operated check valve for secure load holding.
