Airtac SAUD Double Rod Cylinder SAUD80X350
The AirTAC SAUD Double Rod Cylinder SAUD80X350 is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 350mm 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 SAUD80X350
The AirTAC SAUD80X350 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 area. This gives an equal output of 2268 N each way at 0.5 MPa. The unit is shorter than a standard ISO 15552 cylinder of the same bore and uses a 3/8" port.
With a 350mm stroke, external guides are recommended to prevent rod bending under side loads. This SKU has no magnet, so it cannot take a sensor switch. For high heat up to 150 C, specify the Viton H seal.

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 SAUD80X350 Is Used
Twin-Tool Stamping
Drives two synchronized forming tools from opposite rod ends with identical 2268 N force.
Anti-Rotation Diverter
Uses the dual rods to prevent twist while pushing heavy packages on a sorting line.
Is the Airtac SAUD Double Rod Cylinder SAUD80X350 the Right Cylinder?
Choose this 80mm bore when you need 2268 N of equal force in both directions. If you need less, the 63mm bore provides 1402 N both ways; if you need more, the 100mm bore gives 3681 N. A double rod is the right call for anti-rotation guidance or driving twin tools. Mounting is limited to Basic, FA, and LB types, matching the AirTAC SC series. Because the stroke is 350mm, add external side-load support. This SKU lacks the -S magnet, so magnetic sensing is impossible. Note that air cushions only decelerate; use an external rod lock to hold 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 SAUD80X350 FAQ
Because it is a double-rod cylinder, the force is equal in both directions. It provides 2268 N at 0.5 MPa, 3175 N at 0.7 MPa, and 4082 N at 0.9 MPa. The 3/8 inch port supplies air to both chambers.
No. This specific SKU does not include the -S magnet option, so it cannot operate magnetic switches like CMSG or DMSG. You would need external mechanical or proximity sensors.
