Airtac SAUD Double Rod Cylinder SAUD80X40
The AirTAC SAUD Double Rod Cylinder SAUD80X40 is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 40mm 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 SAUD80X40
The AirTAC SAUD80X40 is a double-acting, double-rod profile cylinder featuring a 80mm bore and 40mm stroke. A rod exits both ends, meaning push and pull forces are identical at 2268 N each way at 0.5 MPa. The extruded aluminum barrel keeps the body shorter than an ISO 15552 unit of the same bore.
This model uses a 3/8 inch port and a M20x1.5 rod thread. Since this SKU lacks the -S magnet suffix, it cannot accept magnetic sensors. For high heat up to 150 C, specify the Viton H seal option.

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 SAUD80X40 Is Used
Twin-Spindle Drilling
Drives two synchronized machining spindles from one piston, utilizing the equal force to push both tools into a workpiece simultaneously.
Dual Transfer Pushers
Mounts a pusher on the front rod and a cam on the back rod to trip a mechanical limit switch, sequencing a conveyor line without electronics.
Is the Airtac SAUD Double Rod Cylinder SAUD80X40 the Right Cylinder?
Choose this 80mm bore delivering 2268 N both ways when you need strict anti-rotation guidance or twin tooling. Stepping down, the 63mm bore provides 1402 N, while stepping up to the 100mm bore yields 3681 N. Mounting is limited to Basic, FA flange, and LB foot styles matching the AirTAC SC series. Because this stroke is only 40mm, side-load stress is minimal, but always guide external loads. Remember this specific SKU has no magnet, so sensing is unsupported.
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 SAUD80X40 FAQ
Because it is a double-rod cylinder, 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. The 3/8 inch port feeds both chambers equally.
No, a plain SAUD cylinder drifts without live air; the adjustable 28mm cushions only decelerate near stroke end. For vertical load holding, install an external rod lock or pilot-operated check valve.
