Airtac SAUD Double Rod Cylinder SAUD80X75S
The AirTAC SAUD Double Rod Cylinder SAUD80X75S is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 75mm 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 SAUD80X75S
The AirTAC SAUD80X75S is a double-acting, double-rod profile cylinder. A 25mm rod exits both ends, meaning both faces use the rod-side area. This yields equal push and pull force of 2268 N each way at 0.5 MPa. The extruded aluminium barrel is shorter than an ISO 15552 cylinder of the same 80mm bore. It features a 3/8 inch port and M20x1.5 rod thread.
With the built-in magnet (-S suffix), this model supports CMSG, DMSG, and EMSG switches. The rear protruding rod is perfect for mounting a sensor cam or tripping a switch. A Viton H seal option 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 SAUD80X75S Is Used
Twin-Tool Stamping
Drives two matched forming tools simultaneously from opposite rod ends, ensuring perfectly synchronized contact on the workpiece.
Anti-Rotation Diverter
Pushes a sorting flap on a packaging line while the second rod prevents mechanical twist under high lateral load.
Cam-Triggered Clamping
Actuates a machining fixture while the rear protruding rod carries a cam to trip an external limit switch.
Is the Airtac SAUD Double Rod Cylinder SAUD80X75S the Right Cylinder?
Select this 80mm bore if you need 2268 N of equal force in both directions. Stepping down to a 63mm bore provides 1402 N, while a 100mm bore offers 3681 N. A double rod is the right call for anti-rotation guidance, driving twin tooling, or back-end sensing. Mounting is limited to Basic, FA flange, and LB foot, matching the AirTAC SC series. The -S magnet enables position sensing. For any stroke over 300mm, always use external guides to prevent side-load wear.
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 SAUD80X75S FAQ
Because the 25mm rod exits both ends, the force is equal in both directions. It outputs 2268 N at 0.5 MPa, 3175 N at 0.7 MPa, and 4082 N at 0.9 MPa.
No. A plain cylinder drifts without live air, as the adjustable 28mm cushion only decelerates near stroke end. Use an external rod lock or pilot-operated check valve for secure load holding.
