Airtac SAUD Double Rod Cylinder SAUD80X400S
The AirTAC SAUD Double Rod Cylinder SAUD80X400S is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 400mm 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 SAUD80X400S
The AirTAC SAUD80X400S is a double-acting, double-rod profile cylinder. A 25 mm rod protrudes from both ends, meaning push and pull forces are identical at 2268 N each way at 0.5 MPa. The extruded aluminum barrel is more compact than a standard ISO 15552 unit of the same bore. It features a 3/8 inch port and an M20x1.5 rod thread.
This unit includes the -S magnet option for CMSG, DMSG or EMSG switches. The twin-rod geometry prevents rotation and lets you mount a sensor cam on the back rod. Viton H seals can raise the operating temperature to 150 C.

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 SAUD80X400S Is Used
Twin-Tool Stamping
Drives two synchronized forming tools from one piston, utilizing the equal force on both strokes for balanced metalworking.
Anti-Rotation Diverter
Pushes a lane-guiding gate on a packaging line without twisting, relying on the dual rods for mechanical stability.
Dual-End Pallet Stop
Uses the front rod as a pallet hard-stop while the rear rod trips a physical limit switch to confirm position.
Is the Airtac SAUD Double Rod Cylinder SAUD80X400S the Right Cylinder?
Choose this 80 mm bore if you need 2268 N of equal bidirectional force. Stepping down to the 63 mm bore yields 1402 N, while moving up to the 100 mm bore provides 3681 N, both equal in both directions. A double rod is the right call for anti-rotation guidance, driving twin tools, or rear-rod sensing. Mounting is limited to Basic, FA flange, and LB foot styles, matching the AirTAC SC series. The -S suffix enables solid-state or reed sensing. Because the stroke is 400 mm, use external guides to prevent rod bending under side loads.
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 SAUD80X400S FAQ
The force is equal in both directions because of the 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 inch port feeds both chambers equally.
No, the air cushions only decelerate the piston near the end caps and do not lock the load. To prevent drifting on air loss, you must add an external rod lock or a pilot-operated check valve.
