Airtac SAUD Double Rod Cylinder SAUD80X240S
The AirTAC SAUD Double Rod Cylinder SAUD80X240S is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 240mm 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 SAUD80X240S
The AirTAC SAUD80X240S is a double-acting, double-rod profile cylinder. A Ø25 mm rod protrudes from both ends of the hard-anodized extruded aluminum barrel, meaning both faces use the rod-side area. This yields exactly 2268 N of thrust and pull at 0.5 MPa, 3175 N at 0.7 MPa, and 4082 N at 0.9 MPa. The 3/8" port and M20x1.5 rod thread match the 80 mm bore standard.
Because the piston travels on two rods, it resists torsional twist for synchronized tool driving. The extruded profile is shorter than a standard ISO 15552 unit of the same bore, saving machine space. The -S suffix adds a piston magnet for CMSG, DMSG, or EMSG switches.

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 SAUD80X240S Is Used
Twin-Spindle Drilling
Drives two synchronized machining heads from one piston, using the equal force and torsional stability of the dual rods.
Dual Transfer Pusher
Pushes alternating parts on parallel lanes, with the back rod carrying a cam to trigger a remote reed switch.
Is the Airtac SAUD Double Rod Cylinder SAUD80X240S the Right Cylinder?
Choose this 80 mm bore if your application needs 2268 N each way at 0.5 MPa. Stepping down, the 63 mm bore provides 1402 N both ways; stepping up, the 100 mm bore offers 3681 N. A double-rod design is the right call when you need anti-rotation stability, twin tooling on one axis, or a back rod to trip a switch. Mounting is limited to Basic, FA flange, and LB foot styles, matching the AirTAC SC series. The -S magnet enables position sensing. For this 240 mm stroke, ensure external guide rails carry side 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 SAUD80X240S FAQ
Because the 25 mm rod exits both ends, the push and pull forces are identical: 2268 N at 0.5 MPa, 3175 N at 0.7 MPa, and 4082 N at 0.9 MPa. It never produces a larger single-rod push value.
No, a plain SAUD cylinder drifts without live air. The adjustable 28 mm cushions only decelerate the piston near the stroke ends. For locked load holding on valve center, install an external rod lock or pilot-operated check valve.
