Airtac SAUD Double Rod Cylinder SAUD80X185S
The AirTAC SAUD Double Rod Cylinder SAUD80X185S is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 185mm 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 SAUD80X185S
The AirTAC SAUD80X185S is a double-acting, double-rod profile cylinder. Because a rod exits both ends, the push and pull forces are identical at 2268 N each way at 0.5 MPa. The extruded aluminum barrel keeps the unit shorter than an ISO 15552 cylinder of the same bore. It features a 3/8 inch port and an M20x1.5 rod thread.
This model includes a built-in piston magnet for CMSG, DMSG, or EMSG switches. The dual-rod design provides anti-rotation guidance and lets you mount a sensor cam on the back rod. Viton H seals can raise the operating temperature 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 SAUD80X185S Is Used
Twin-Tool Stamping
Drives two synchronized forming tools from one piston, using the equal 2268 N force to deliver matched impact pressure on both ends.
Anti-Rotation Lift
Lifts vertical loads up to 116 kg without twisting, relying on the dual rods for geometric stability during elevation changes.
Cam-Triggered Sorting
Uses the protruding back rod to trip an external CMSG reed switch, confirming full extension while the front rod pushes packages.
Is the Airtac SAUD Double Rod Cylinder SAUD80X185S the Right Cylinder?
Choose this 80 mm bore when your application needs equal force both ways, measuring 2268 N at 0.5 MPa. Stepping down to a 63 mm bore yields 1402 N, while a 100 mm bore provides 3681 N. A double rod is the right call for anti-rotation stability, driving twin tooling, or back-end switch actuation. Mounting is limited to Basic, FA flange, and LB foot brackets, matching the AirTAC SC series. The -S suffix enables electronic position sensing. For this 185 mm stroke, ensure external guides support any side loads 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 SAUD80X185S FAQ
The force is equal in both directions because it is a double-rod design. It outputs 2268 N at 0.5 MPa, 3175 N at 0.7 MPa, and 4082 N at 0.9 MPa.
No, a plain cylinder drifts without live air; the adjustable 28 mm cushions only decelerate near stroke end. Use an external rod lock or pilot-operated check valve for load holding.
