Airtac SAUD Double Rod Cylinder SAUD100X125
The AirTAC SAUD Double Rod Cylinder SAUD100X125 is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 125mm stroke, 1/2" 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 SAUD100X125
The AirTAC SAUD100X125 is a double-acting profile-type cylinder with a 100 mm bore and 125 mm stroke. A 25 mm rod exits both ends, meaning push and pull force are identical at 3681 N each way at 0.5 MPa. The extruded aluminum barrel makes it shorter than an ISO 15552 cylinder of the same bore. It features a 1/2 inch port, M20x1.5 rod thread, and 29 mm adjustable cushions at both ends.
Because this SKU lacks the -S magnet option, it cannot accept CMSG, DMSG, or EMSG sensors. The twin-rod geometry provides anti-rotation guidance and lets you drive two tools at once. For high-heat environments up to 150 C, specify the Viton H seal.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3682 N | 3682 N |
| 0.7 MPa | 5154 N | — |
| Max (@1.0 MPa) | 751 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 SAUD100X125 Is Used
Twin-Tool Stamping
Drives two synchronized forming tools from one piston, using the equal 3681 N force to press components simultaneously without rotational twist.
Heavy Pallet Lift
Raises loaded pallets vertically, leveraging the 188 kg safe lift capacity while the dual rods prevent the platform from binding or rotating.
Dual Transfer Arms
Powers opposing transfer arms on a conveyor line, ensuring perfectly timed part handoffs by pushing and pulling with identical 3681 N force.
Is the Airtac SAUD Double Rod Cylinder SAUD100X125 the Right Cylinder?
Choose this 100 mm bore if you need substantial equal force both ways. Step down to the 80 mm bore for 2268 N at 0.5 MPa, or step up if you require more than 3681 N. A double rod is the right call for anti-rotation stability or mounting twin tooling. You can use SC-series FA flange or LB foot mounts; no FB, CA, or CB brackets exist. At 125 mm stroke side loading is minimal, but always guide the load for strokes over 300 mm. Remember this non-magnet SKU cannot host a sensor. To hold a load on air loss, add an external rod lock or pilot check valve, as cushions only decelerate.
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 SAUD100X125 FAQ
The force is equal both ways because the rod exits both ends. It outputs 3681 N at 0.5 MPa, 5153 N at 0.7 MPa, and 6626 N at 0.9 MPa. The 1/2 inch port feeds the 100 mm bore to achieve this across a 30-800 mm/s speed range.
No, this specific SKU does not include a magnet, so it cannot accept CMSG, DMSG, or EMSG switches. You would need the -S option for sensing. The rear rod can still mechanically trip an external switch if needed.
