Airtac SAUD Double Rod Cylinder SAUD80X550S
The AirTAC SAUD Double Rod Cylinder SAUD80X550S is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 550mm 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 SAUD80X550S
The AirTAC SAUD80X550S is a double-acting, double-rod profile cylinder. A rod exits both ends, meaning both faces use the rod-side area and push or pull force is equal at 2268 N each way at 0.5 MPa. The 3/8 inch port and M20x1.5 rod thread handle robust flow. An extruded aluminium barrel keeps the unit shorter than a standard ISO 15552 type of the same bore.
This -S variant includes a piston magnet for CMSG, DMSG or EMSG switches. The second rod provides anti-rotation guidance and can carry a sensor cam. A Viton H seal option raises the operating ceiling 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 SAUD80X550S Is Used
Dual-Tool Transfer
Drives two synchronized workpieces from opposite rod ends on a 550 mm conveyor indexing station.
Anti-Rotation Gripper
Uses the twin rods to prevent twist during heavy clamping operations requiring strict parallelism.
Cam-Trip Limiting
Mounts a switch cam on the back rod to mechanically trip external proximity sensors.
Is the Airtac SAUD Double Rod Cylinder SAUD80X550S the Right Cylinder?
Choose this 80 mm bore delivering 2268 N both ways when your mechanism needs synchronized motion or anti-twist guidance over 550 mm. If you need less force, step down to the 63 mm bore for 1402 N. If you need more, the 100 mm bore provides 3681 N. Mounting is limited to Basic, FA and LB types matching the AirTAC SC series. Because the stroke is 550 mm, fit external guides to prevent rod bending under side loads. The -S magnet enables position sensing, while a plain SKU cannot take a sensor.
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 SAUD80X550S FAQ
The force is equal in both directions because it is a double-rod cylinder. It outputs 2268 N at 0.5 MPa, 3175 N at 0.7 MPa, and 4082 N at 0.9 MPa.
No, the air cushion only decelerates the piston near stroke end. For load holding on air loss, you must fit an external rod lock or pilot-operated check valve.
