Airtac SAUD Double Rod Cylinder SAUD80X800S
The AirTAC SAUD Double Rod Cylinder SAUD80X800S is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 800mm 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 SAUD80X800S
The AirTAC SAUD80X800S is a double-acting, double-rod profile cylinder. A piston rod exits both ends, meaning both faces use the rod-side area and the output force is equal in both directions. This 80mm bore unit delivers 2268 N each way at 0.5 MPa. It features a 3/8 inch port and an M20x1.5 rod thread. The extruded aluminum profile barrel makes it shorter than a standard ISO 15552 cylinder of the same bore.
Because the rear rod protrudes from the back cap, it is ideal for driving a sensor cam or tripping a switch. The -S suffix indicates a built-in 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 SAUD80X800S Is Used
Twin-Tool Stamping
Drives two identical punches from one piston, ensuring synchronized contact on both ends of the workpiece.
Anti-Rotation Diverter
Uses the dual rods to prevent twist during long 800mm travel, keeping the diverter arm perfectly aligned.
Cam-Triggered Sorting
Uses the rear protruding rod to physically trip a limit switch, confirming full retraction without internal magnets.
Is the Airtac SAUD Double Rod Cylinder SAUD80X800S 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 yields 3681 N. Choose this 80mm model when you need 2268 N of equal push and pull force. It is the right call for anti-rotation guidance, twin-tool driving, or back-end sensing. Mounting is limited to Basic, FA flange, and LB foot styles, compatible with the AirTAC SC series. The -S magnet allows solid switch mounting. Because the stroke is 800mm, you must support the load with external guides to prevent rod bending and side-load damage.
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 SAUD80X800S FAQ
The force is equal both ways because of the double-rod design. It provides 2268 N at 0.5 MPa, 3175 N at 0.7 MPa, and 4082 N at 0.9 MPa. It never outputs a larger single-rod push value.
No, a plain cylinder drifts on air loss. The adjustable air cushion only decelerates the piston near the stroke end. For a held load, you must add an external rod lock or a pilot-operated check valve.
