Airtac SAUD Double Rod Cylinder SAUD80X290
The AirTAC SAUD Double Rod Cylinder SAUD80X290 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 SAUD80X290
The AirTAC SAUD80X290 is a double-acting, double-rod profile cylinder. A Ø25 mm rod exits both ends of the hard-anodized extruded aluminum barrel, meaning both faces use the rod-side area. The output is perfectly symmetrical, delivering 2268 N of force each way at 0.5 MPa. The unit features a 3/8" port, M20x1.5 rod threads, and 28 mm adjustable air cushions at both ends.
Because the rod protrudes at the rear, you can mount a sensor cam directly onto it, though this specific SKU lacks a magnet so it cannot take CMSG or DMSG switches. The profile design is notably shorter than a standard ISO 15552 cylinder of the same 80 mm bore.

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 SAUD80X290 Is Used
Twin-Tool Transfer
Drives two synchronized gripping jaws from opposite rod ends to transfer heavy castings between machining centers.
Anti-Rotation Press
Uses the dual rods to prevent piston twist during a 290 mm downward pressing stroke on aluminum housings.
Rear-Cam Tripping
Uses the back rod extension to mechanically trip a physical limit switch at mid-stroke for tool validation.
Is the Airtac SAUD Double Rod Cylinder SAUD80X290 the Right Cylinder?
Choose this 80 mm bore when your application requires equal push and pull forces, such as anti-rotation guidance or driving two tools at once. Stepping down, the 63 mm bore provides 1402 N each way at 0.5 MPa; stepping up, the 100 mm bore yields 3681 N. Mounting is limited to Basic, FA, and LB styles, matching the AirTAC SC series. At 290 mm stroke, external side-load guidance is recommended to prevent rod binding. Remember this SKU has no magnet, so magnetic sensing is impossible without a different variant.
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 SAUD80X290 FAQ
The force is equal in both directions because it is a double-rod design. It outputs 2268 N at 0.5 MPa, 3175 N at 0.7 MPa, and 4082 N at 0.9 MPa. The 3/8" port and 28 mm cushions handle the flow for these loads.
No, a plain double-rod cylinder drifts without live air; the cushions only decelerate near the stroke ends. For secure load holding, install an external rod lock or a pilot-operated check valve.
