Airtac SAUD Double Rod Cylinder SAUD100X40
The AirTAC Airtac SAUD Double Rod Cylinder SAUD100X40 is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 40mm 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 SAUD100X40
The AirTAC SAUD100X40 is a double-acting double-rod profile cylinder featuring a 100mm bore and 40mm stroke. A 25mm rod exits both ends, meaning push and pull forces are identical at 3681 N each way at 0.5 MPa. The extruded hard-anodized aluminum barrel keeps the unit shorter than an ISO 15552 cylinder of the same bore. It uses a 1/2 inch port and M20x1.5 rod threads.
This twin-rod layout provides excellent anti-rotation guidance and lets you mount tooling on both faces simultaneously. This SKU lacks a magnet, so it cannot accept CMSG or DMSG sensors. For high-heat environments up to 150 C, specify the Viton H seal option.

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 SAUD100X40 Is Used
Twin-Spindle Drilling
Drives two opposing machining heads simultaneously with equal 3681 N thrust and precise anti-rotation stability.
Balanced Vertical Lift
Raises and lowers 188 kg payloads smoothly using the equal bidirectional force and adjustable 29mm cushions.
Dual-End Ejection
Pushes parts from either end of an assembly station using the synchronized 25mm rods exiting both covers.
Is the Airtac SAUD Double Rod Cylinder SAUD100X40 the Right Cylinder?
Choose this 100mm bore if your application requires the maximum equal-both-ways thrust of 3681 N at 0.5 MPa. If you need less force, step down to the 80mm bore which provides 2268 N both ways. The double-rod architecture is ideal when you need strict anti-twist control or wish to drive two tools at once. Mounting is limited to Basic, FA flange, and LB foot styles, matching the AirTAC SC series. Because this specific SKU has no internal magnet, you cannot add position switches; select a -S variant if you require sensing. At a 40mm stroke, side loading is minimal, but always support external guide rods for any stroke exceeding 300mm.
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 SAUD100X40 FAQ
The force is equal in both directions due to the double-rod design. It outputs 3681 N at 0.5 MPa, 5153 N at 0.7 MPa, and 6626 N at 0.9 MPa.
No. A plain cylinder drifts without live air, as the adjustable cushion only decelerates near stroke end. Use an external rod lock or pilot-operated check valve for held loads.
