Airtac SAUD Double Rod Cylinder SAUD80X40S
The AirTAC SAUD Double Rod Cylinder SAUD80X40S is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 40mm 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 SAUD80X40S
The AirTAC SAUD80X40S is a double-acting, double-rod profile cylinder. A 25mm rod protrudes from both ends of the hard-anodized aluminum extruded barrel, meaning both faces lose rod area. This yields perfectly equal push and pull force of 2268 N each way at 0.5 MPa. The 3/8 inch port feeds the chambers, and the unit is noticeably shorter than a standard ISO 15552 cylinder of the same 80mm bore.
Because this SKU includes the -S suffix, it has a built-in piston magnet for CMSG, DMSG or EMSG switches. You can also specify Viton H seals to raise the operating temperature from 70 C up 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 SAUD80X40S Is Used
Twin-Tool Transfer
Drives two opposing grippers simultaneously from one piston, utilizing the equal force on both rod ends to pick and place parts evenly.
Cam-Operated Sensing
Uses the extended back rod to physically trip a limit switch or carry a sensor cam, providing precise end-of-stroke confirmation in tight spaces.
Anti-Rotation Pressing
Applies 2268 N of balanced clamping pressure without twisting, ideal for pressing bearings where a single rod might bind under offset loads.
Is the Airtac SAUD Double Rod Cylinder SAUD80X40S the Right Cylinder?
Choose this 80mm bore delivering 2268 N both ways when your mechanism needs anti-rotation guidance or twin tooling driven from one piston. Stepping down, the 63mm bore provides 1402 N both ways; stepping up, the 100mm bore yields 3681 N. Mounting is limited to Basic, FA flange, and LB foot, matching the AirTAC SC series. The -S magnet allows solid rear-rod switch cam sensing. Since the 40mm stroke is short, side-load risks are minimal, but always guide external loads 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 SAUD80X40S FAQ
The force is equal in both directions because a 25mm rod exits both ends. It produces 2268 N at 0.5 MPa, 3175 N at 0.7 MPa, and 4082 N at 0.9 MPa.
No, the adjustable 28mm air cushions only decelerate the piston near stroke end. For load holding on air loss, you must fit an external rod lock or pilot-operated check valve.
