Airtac SAUD Double Rod Cylinder SAUD80X450S
The AirTAC SAUD Double Rod Cylinder SAUD80X450S is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 450mm 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 SAUD80X450S
The AirTAC SAUD80X450S is a double-acting, double-rod profile cylinder. A rod exits both ends, so the push and pull force is equal at 2268 N each way at 0.5 MPa. The extruded aluminum barrel is shorter than an ISO 15552 cylinder of the same 80 mm bore. It uses a 3/8 inch port and an M20x1.5 rod thread.
This unit includes the -S magnet option for CMSG, DMSG, or EMSG switches. The second rod provides anti-rotation guidance and can carry a sensor cam. Standard seals handle -20 to +70 C, while a Viton H option extends this to 0-150 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 SAUD80X450S Is Used
Twin-Tool Machining
Drives two opposing spindles simultaneously with identical 2268 N force, ensuring balanced material removal on both faces.
Anti-Rotation Diverter
Uses the dual rods to prevent twist during a 450 mm sweep, keeping the diverter paddle perfectly aligned on the belt line.
Cam-Trip Switching
Uses the protruding back rod as a mechanical cam to trigger external CMSG reed switches at mid-stroke positions.
Is the Airtac SAUD Double Rod Cylinder SAUD80X450S the Right Cylinder?
Choose this 80 mm bore when you need 2268 N of equal force in both directions over a 450 mm stroke. Stepping down, the 63 mm bore provides 1402 N both ways; stepping up, the 100 mm bore yields 3681 N. A double rod is the right call for anti-rotation tasks, driving twin tooling, or mounting a switch cam on the back end. Mounting is limited to Basic, FA flange, and LB foot styles, matching the AirTAC SC series. Because the stroke is 450 mm, add external guide rails to prevent rod bending under side loads. The -S suffix enables position sensing.
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 SAUD80X450S 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 bore is 80 mm with a 3/8 inch port.
No, a plain SAUD cylinder will drift 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.
