Airtac SAUD Double Rod Cylinder SAUD80X80S
The AirTAC SAUD Double Rod Cylinder SAUD80X80S is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 80mm 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 SAUD80X80S
The AirTAC SAUD80X80S is a double-acting, double-rod profile cylinder. A Ø25 mm rod exits both ends of the hard-anodized extruded aluminum barrel, meaning both faces use the rod-side area. This yields an equal push and pull force of 2268 N each way at 0.5 MPa. The 3/8 inch port and M20x1.5 rod thread handle robust airflow and mounting. Because of the twin rods, the unit resists torsional twist and can drive two tools simultaneously.
This 80 mm bore actuator is notably shorter than a standard ISO 15552 cylinder of the same size, yet uses SC-series FA and LB mounting accessories. The integrated -S piston magnet enables CMSG, DMSG, or EMSG switch mounting along the profile slot.

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 SAUD80X80S Is Used
Twin-Spindle Drilling
Drives two synchronized machining heads from one piston, ensuring both holes are bored simultaneously without rotational drift.
Dual Transfer Pusher
Pushes a workpiece forward while the back rod retracts a return chute, using the equal force to maintain balanced cycle timing.
Cam-Operated Switching
Uses the protruding rear rod as a mechanical cam to trigger external limit switches, with the built-in magnet for internal DMSG sensors.
Is the Airtac SAUD Double Rod Cylinder SAUD80X80S the Right Cylinder?
Choose this 80 mm bore if your application requires 2268 N of equal bidirectional force at 0.5 MPa. Stepping down, the 63 mm bore provides 1402 N both ways, while the 100 mm bore offers 3681 N for heavier demands. A double-rod design is the right call when you need strict anti-rotation guidance, dual-tool driving, or a back rod to trip a sensor cam. Mounting is limited to Basic, FA, and LB styles. The included -S magnet supports electronic position sensing. For this 80 mm stroke, side loads are minimal, but any stroke over 300 mm requires external guide rails to prevent rod 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 SAUD80X80S FAQ
Because the double-rod design uses the rod-side area on both faces, 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 equally.
No, a plain double-rod cylinder drifts without live air. The adjustable 28 mm cushions only decelerate the piston near the stroke ends; they do not lock it. For secure load holding, install an external rod lock or a pilot-operated check valve.
