Airtac SAUD Double Rod Cylinder SAUD80X15S
The AirTAC SAUD Double Rod Cylinder SAUD80X15S is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 15mm 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 SAUD80X15S
The AirTAC SAUD80X15S is a double-acting, double-rod profile cylinder. A Ø25 mm rod exits both ends, meaning the push and pull forces are identical at 2268 N each way when operating at 0.5 MPa. The extruded hard-anodized aluminum barrel makes it shorter than a standard ISO 15552 unit of the same bore. This -S variant includes a piston magnet for position sensing.
With a 15 mm stroke and 3/8" port, it provides stable anti-rotation guidance. You can fit CMSG, DMSG or EMSG switches to the slot. For high-temperature environments up to 150 C, specify the Viton H seal option.

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 SAUD80X15S Is Used
Gripping Clamp
Applies 2268 N of equal clamping and release force to hold a workpiece securely during machining.
Twin Tool Drive
Drives two opposing forming tools simultaneously from one piston, keeping timing perfectly synchronized.
Rear Cam Sensing
Uses the protruding back rod as a mechanical cam to trigger an external limit switch for cycle validation.
Is the Airtac SAUD Double Rod Cylinder SAUD80X15S the Right Cylinder?
Choose this 80 mm bore if your application requires 2268 N of equal force in both directions over a very short 15 mm travel. Stepping down to the 63 mm bore drops the equal force to 1402 N, while moving up to the 100 mm bore increases it to 3681 N at 0.5 MPa. The double-rod architecture is ideal when you need precise anti-rotation resistance, twin tooling on one axis, or a rear rod to trip a switch. Mounting is limited to Basic, FA flange, and LB foot styles, matching the AirTAC SC series. Because the stroke is only 15 mm, side-load risks are minimal, but always guide external loads. The built-in magnet allows seamless sensor integration.
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 SAUD80X15S FAQ
Because the double rod occupies area on both faces, the force is equal in both directions: 2268 N at 0.5 MPa, 3175 N at 0.7 MPa, and 4082 N at 0.9 MPa. The 3/8" port feeds both chambers.
No, the air cushions only decelerate the piston near the stroke ends; they do not lock the load. To prevent drift on air loss, you must install an external rod lock or a pilot-operated check valve.
