Airtac SAUD Double Rod Cylinder SAUD80X35S
The AirTAC SAUD Double Rod Cylinder SAUD80X35S is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 35mm 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 SAUD80X35S
The AirTAC SAUD80X35S is a double-acting, double-rod profile cylinder. A Ø25 mm rod exits both ends of the hard-anodized extruded aluminum barrel, making the push and pull force equal at 2268 N each way at 0.5 MPa. This compact body is shorter than a standard ISO 15552 unit of the same bore. It features a 3/8 inch port and an integrated magnet for switch mounting.
Because both faces use the rod-side area, output is perfectly symmetrical. The rear rod is ideal for carrying a sensor cam. High-temperature Viton H seals can extend operation from -20 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 SAUD80X35S Is Used
Twin-Tool Stamping
Drives two synchronized forming tools from one piston, ensuring parallel contact without rotational twist on the workpiece.
Dual-End Diverting
Uses the rear rod to trip a mechanical flag while the front rod pushes a package, keeping control logic simple.
Guided Lift Stops
Lifts and lowers a 100 kg pallet stopper gate where equal push and pull force prevents sagging during travel.
Is the Airtac SAUD Double Rod Cylinder SAUD80X35S the Right Cylinder?
Choose this 80 mm bore when you need 2268 N of equal force in both directions over a 35 mm stroke. If your application requires less thrust, the 63 mm bore provides 1402 N both ways; if you need more, the 100 mm bore offers 3681 N. The twin rods prevent rotation and support twin tooling. Mounting is limited to Basic, FA flange, and LB foot styles, matching the AirTAC SC series. The -S suffix means a magnet is installed for CMSG, DMSG, or EMSG switches. For this 35 mm stroke, side loads are minimal, but always guide the external load to prevent binding.
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 SAUD80X35S 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 supplies air to both chambers equally.
No, a plain double-rod cylinder drifts without live air. The adjustable 28 mm cushions only decelerate the piston near the stroke ends. Use an external rod lock or pilot-operated check valve for secure load holding.
