Airtac SAUD Double Rod Cylinder SAUD80X65S
The AirTAC SAUD Double Rod Cylinder SAUD80X65S is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 65mm 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 SAUD80X65S
The AirTAC SAUD80X65S is a double-acting, double-rod profile cylinder. A Ø25 mm rod protrudes from both ends of the hard-anodized aluminum barrel, meaning both faces use the rod-side area. Output is equal in both directions at 2268 N each way at 0.5 MPa. The 3/8 inch port supplies air, while the M20x1.5 rod threads handle mounting. This extruded profile body is noticeably shorter than an ISO 15552 unit of the same bore.
Because the rod exits both ends, you gain anti-rotation guidance and can mount a sensor cam on the back rod. This -S variant includes a piston magnet for CMSG, DMSG or EMSG switches. A high-temperature Viton H seal option extends operation 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 SAUD80X65S Is Used
Twin-Tool Synchronization
Drives two opposing grippers or forming tools simultaneously from one piston, ensuring perfectly matched timing and equal force during clamping.
Back-End Switch Cam
Uses the protruding rear rod as a mechanical cam to trip CMSG or DMSG sensors, providing precise end-of-stroke confirmation in tight spaces.
Anti-Rotation Lifting
Lifts and lowers heavy chucks or pallets up to 116 kg without twisting, relying on the dual rods for strict linear guidance.
Is the Airtac SAUD Double Rod Cylinder SAUD80X65S the Right Cylinder?
Select this 80 mm bore if your application requires non-rotating accuracy or twin tooling driven from one piston. The equal push and pull force of 2268 N at 0.5 MPa sits between the 63 mm bore (1402 N) and the 100 mm bore (3681 N). Mounting is limited to Basic, FA flange, and LB foot styles, matching the AirTAC SC series. The built-in magnet allows direct switch mounting. For this 65 mm stroke side loads are minimal, but any stroke over 300 mm requires external guide rails 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 SAUD80X65S FAQ
Because it is a double-rod cylinder, 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 and 28 mm adjustable cushions ensure smooth operation.
No. The air cushions only decelerate the piston near the stroke ends; they do not lock the load. If air is lost, the piston will drift. For secure load holding, install an external rod lock or a pilot-operated check valve.
