Airtac SAUD Double Rod Cylinder SAUD80X25S
The AirTAC SAUD Double Rod Cylinder SAUD80X25S is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 25mm 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 SAUD80X25S
The AirTAC SAUD80X25S is a double-acting, double-rod profile cylinder. A rod exits both ends on one piston, meaning both faces use the rod-side area and the output force is equal in both directions. This 80mm bore delivers 2268 N each way at 0.5 MPa, utilizing a 3/8 inch port and M20x1.5 rod threads.
Because both chambers carry a rod, you get identical push and pull power for non-rotating or synchronized tasks. The extruded aluminum profile is shorter than an ISO 15552 cylinder of the same bore. This -S variant includes a piston magnet for CMSG, DMSG, or EMSG switches.

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 SAUD80X25S Is Used
Twin-Spindle Machining
Drives two synchronized machining heads from one piston, ensuring perfectly matched feed rates via the dual rod outputs.
Dual Transfer Pushers
Pushes a workpiece forward while simultaneously retracting a return tool on the back side, halving cycle time.
Cam-Triggered Sorting
Uses the protruding back rod as a mechanical cam to trip an external limit switch, confirming stroke completion.
Is the Airtac SAUD Double Rod Cylinder SAUD80X25S the Right Cylinder?
When sizing this double-rod unit, compare both ways: the 63mm bore yields 1402 N at 0.5 MPa, while the 100mm bore provides 3681 N. Choose this 80mm model when you need 2268 N of equal bidirectional force for anti-rotation guidance, twin tooling, or mounting a switch cam on the back rod. Mounting is limited to Basic, FA flange, and LB foot options, matching the AirTAC SC series. At a 25mm stroke, side-load stress is minimal, but always guide external loads on longer strokes. Note that a plain cylinder drifts without live air; use an external rod lock for load holding.
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 SAUD80X25S FAQ
The force is equal both ways because a rod exits both ends. It outputs 2268 N at 0.5 MPa, 3175 N at 0.7 MPa, and 4082 N at 0.9 MPa. We never quote a larger single-rod push value for this double-acting profile cylinder.
No, a plain cylinder drifts without live air. The adjustable 28mm air cushions only decelerate the piston near stroke end; they do not lock the load. For secure holding, install an external rod lock or a pilot-operated check valve.
