Airtac SAUD Double Rod Cylinder SAUD80X140S
The AirTAC SAUD Double Rod Cylinder SAUD80X140S is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 140mm 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 SAUD80X140S
The AirTAC SAUD80X140S is a double-acting, double-rod profile cylinder. A 25 mm rod exits both ends of the hard-anodized aluminum barrel, meaning both faces use the rod-side piston area. This yields identical push and pull thrust of 2268 N each way at 0.5 MPa. The extruded profile makes it shorter than an ISO 15552 unit of the same bore.
Because the rear rod protrudes, it readily carries a switch cam or drives a second tool. This -S variant includes a piston magnet for CMSG, DMSG or EMSG sensors. The 3/8 inch port and 28 mm adjustable cushions handle 30-800 mm/s speeds.

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 SAUD80X140S Is Used
Twin-Tool Stamping
Drives two identical punches simultaneously from opposite rod ends, ensuring perfectly synchronized forming operations.
Anti-Rotation Diverter
Pushes a sorting gate across a belt without twisting, using the inherent torsional resistance of the dual-rod assembly.
Cam-Trip Sequencing
Uses the extended rear rod to physically trigger an external limit switch, confirming full stroke completion.
Is the Airtac SAUD Double Rod Cylinder SAUD80X140S the Right Cylinder?
Select this 80 mm bore when you need 2268 N of equal bidirectional force at 0.5 MPa. If your application requires less thrust, step down to the 63 mm bore delivering 1402 N both ways. If you need more power, the 100 mm bore offers 3681 N in each direction. A double-rod design is the right call for anti-rotation guidance, twin-tool driving, or back-end switch tripping. Mounting is limited to Basic, FA flange, and LB foot styles, matching the AirTAC SC series. The included -S magnet allows solid-state or reed sensing. For any stroke at or over 300 mm, always use 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 SAUD80X140S FAQ
The double-rod design provides equal thrust in both directions. It delivers 2268 N at 0.5 MPa, 3175 N at 0.7 MPa, and 4082 N at 0.9 MPa. There is no larger single-rod push value.
No. The air cushions only decelerate the piston near the end caps; they do not act as a brake. For secure load holding on air loss, install an external rod lock or pilot-operated check valve.
