Airtac SAUD Double Rod Cylinder SAUD80X280
The AirTAC SAUD Double Rod Cylinder SAUD80X280 is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 280mm 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 SAUD80X280
The AirTAC SAUD80X280 is a double-acting, double-rod profile cylinder with an 80mm bore and 280mm stroke. A rod protrudes from both ends, meaning push and pull forces are identical at 2268N each way at 0.5MPa. The extruded aluminum barrel keeps the unit shorter than a standard ISO 15552 cylinder of the same size.
It features a 3/8 inch port, M20x1.5 rod thread, and 28mm adjustable air cushions at both ends. This non-magnet SKU cannot host reed sensors. A Viton H seal option extends operation to 150C.

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 SAUD80X280 Is Used
Twin Spindle Drilling
Drives two synchronized machining heads from one piston, ensuring perfectly balanced feed rates across both tools without torsional twist.
Dual Belt Diverter
Pushes opposing sorting guides simultaneously from a central mount, using the equal bidirectional force to reposition packages cleanly.
Is the Airtac SAUD Double Rod Cylinder SAUD80X280 the Right Cylinder?
Select this 80mm bore if your application demands equal force in both directions, yielding 2268N at 0.5MPa. Stepping down, the 63mm bore provides 1402N both ways; stepping up, the 100mm bore offers 3681N. The dual-rod design is ideal for anti-rotation guidance or driving twin tooling simultaneously. Mounting is limited to Basic, FA flange, and LB foot brackets, matching the AirTAC SC series. Since this lacks the -S magnet suffix, it cannot accept CMSG or DMSG switches. For this 280mm stroke, ensure external load guides are used to prevent side-loading damage.
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 SAUD80X280 FAQ
The force is equal in both directions due to the double-rod design. It outputs 2268N at 0.5MPa, 3175N at 0.7MPa, and 4082N at 0.9MPa. The 3/8 inch port supplies air to both chambers equally.
No. The air cushions only decelerate the piston near stroke end and do not act as a brake. For load holding on air loss, you must install an external rod lock or pilot-operated check valve.
