Airtac SAUD Double Rod Cylinder SAUD80X90S
The AirTAC SAUD Double Rod Cylinder SAUD80X90S is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 90mm 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 SAUD80X90S
The AirTAC SAUD80X90S is a double-acting, double-rod profile cylinder. A Ø25 mm rod protrudes from both ends of the hard-anodized extruded aluminum barrel, meaning both faces use the rod-side piston area. This yields exactly 2268 N of output force in both directions at 0.5 MPa. The 3/8 inch port supplies air, while the M20x1.5 rod threads and 28 mm adjustable cushions manage heavy loads.
Because it is a profile-type design, the body is noticeably shorter than a standard ISO 15552 cylinder of the same bore. The built-in magnet (-S) allows CMSG, DMSG, or EMSG switches to track piston position.

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 SAUD80X90S Is Used
Synchronized Gripper Transfer
Drives opposing grippers simultaneously from a single compact body, ensuring parts are centered without torsional twist during high-speed transfers.
Twin-Tool Stamping Station
Mounts two separate forming tools on opposite rod ends to cycle sequentially or mirror each other, doubling output in a tight footprint.
Rear-Cam Position Verification
Uses the extended back rod to physically trip a limit switch or carry a magnetic sensor cam, providing a hard mechanical backup for primary stroke confirmation.
Is the Airtac SAUD Double Rod Cylinder SAUD80X90S the Right Cylinder?
When sizing this 80 mm bore, step down to the 63 mm version (1402 N both ways at 0.5 MPa) for lighter duty, or up to the 100 mm bore (3681 N both ways) if you need more thrust. Choose the SAUD80X90S twin-rod format when your mechanism requires strict anti-rotation guidance, needs to drive two tools in parallel, or when you must mount a sensor cam on the back rod. Mounting is limited to Basic, FA flange, and LB foot brackets, matching the AirTAC SC series. The -S magnet enables electronic or reed sensing. For any stroke over 300 mm, add external guide rails to prevent side-load 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 SAUD80X90S FAQ
The force is equal in both directions because of the double-rod design. It generates 2268 N at 0.5 MPa, 3175 N at 0.7 MPa, and 4082 N at 0.9 MPa. The 3/8 inch port feeds both chambers equally.
The -S suffix denotes a built-in piston magnet for CMSG, DMSG, or EMSG switches. It does not hold a load on air loss; the cushions only decelerate near stroke end. For load holding, install an external rod lock or pilot-operated check valve.
