Airtac SAUD Double Rod Cylinder SAUD80X700S
The AirTAC SAUD Double Rod Cylinder SAUD80X700S is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 700mm 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 SAUD80X700S
The AirTAC SAUD80X700S is a double-acting, double-rod profile cylinder. A 25mm rod exits both ends of the hard-anodized aluminum barrel, meaning both faces use the rod-side piston area. This yields equal push and pull force of 2268 N each way at 0.5 MPa. The extruded profile body is noticeably shorter than a standard ISO 15552 unit of the same bore. It features a 3/8 inch port, M20x1.5 rod thread, and adjustable air cushions of 28mm at each end.
Because this SKU includes the -S magnet option, it directly supports CMSG, DMSG, and EMSG switches for position detection. The twin-rod design is ideal for anti-rotation guidance or driving two tools at once, and the protruding back rod serves as a perfect cam for rear-mounted sensors. For high-temperature environments up to 150 C, specify the Viton H seal option.

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 SAUD80X700S Is Used
Dual-Tool Transfer
Simultaneously drives two gripping jaws on a wide conveyor line, keeping the payload perfectly synchronized without twisting.
Anti-Rotation Lift
Raises and lowers a 100 kg machining fixture with equal force both ways, using the twin rods to prevent platform rotation.
Rear-Cam Sensing
Uses the protruding back rod as a mechanical cam to trigger rear-mounted CMSG switches in a tight automation cell.
Is the Airtac SAUD Double Rod Cylinder SAUD80X700S the Right Cylinder?
Choose this 80mm bore when an application demands 2268 N of equal force in both directions. If you need less thrust, step down to the 63mm bore which provides 1402 N both ways; if you need more, the 100mm bore offers 3681 N. A double-rod configuration is the right call when you need anti-twist stability, synchronized twin-tool driving, or rear-end switch actuation. Mounting is limited to Basic, FA flange, and LB foot styles, matching the AirTAC SC series. Because the 700mm stroke is quite long, always use external guide rails to prevent rod bending and absorb side loads. The included -S magnet enables electronic or reed sensing.
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 SAUD80X700S FAQ
The force is equal in both directions because the double-rod design uses the rod-side area on both faces. It outputs 2268 N at 0.5 MPa, 3175 N at 0.7 MPa, and 4082 N at 0.9 MPa. The bore is 80mm with a 3/8 inch port.
No, a plain double-rod cylinder will drift if air is lost or the valve is centered. The adjustable 28mm cushions only decelerate the piston near the stroke ends. To hold a load securely, install an external rod lock or a pilot-operated check valve.
