Airtac SAUD Double Rod Cylinder SAUD100X240S
The AirTAC Airtac SAUD Double Rod Cylinder SAUD100X240S is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 240mm 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 SAUD100X240S
The AirTAC SAUD100X240S 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 use the rod-side piston area. This yields perfectly equal push and pull force of 3681 N each way at 0.5 MPa. The unit is shorter than an ISO 15552 cylinder of the same 100mm bore.
Because the rear rod extends outward, it serves as an excellent cam to trip external switches or carry a sensor bracket. This specific SKU includes the -S magnet for internal CMSG, DMSG or EMSG switches. The 1/2" port drives the 30-800 mm/s speed range.

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 SAUD100X240S Is Used
Twin-Spindle Machining
Drives two opposing machining heads with perfectly synchronized 3681 N force, using the rigid 25mm dual rods to prevent spindle twist.
Dual-End Transfer Pusher
Pushes a workpiece forward on the main stroke while the rearward rod simultaneously retracts a diverter gate on the return.
Vertical Lift Fixture
Lifts a balanced 188 kg payload vertically using the equal bidirectional force, relying on the back rod cam to trigger limit sensors.
Is the Airtac SAUD Double Rod Cylinder SAUD100X240S the Right Cylinder?
Select this 100mm bore when your application demands identical force in both directions, which here is 3681 N at 0.5 MPa. If you need less force, the 80mm bore provides 2268 N. If you need more, you are at the top of the range. The double-rod architecture is the right call for anti-rotation guidance, driving twin tooling, or using the back rod for position sensing. Mounting is limited to Basic, FA flange, or LB foot styles, matching the AirTAC SC series. At 240mm stroke, side loads are minimal, but always guide the load externally on longer strokes. For high heat up to 150 C, specify the Viton H seal. Remember that air cushions only decelerate; use a pilot-operated check valve for load holding.
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 SAUD100X240S FAQ
The force is equal both ways because a 25mm rod exits both ends. It generates 3681 N at 0.5 MPa, 5153 N at 0.7 MPa, and 6626 N at 0.9 MPa. The 1/2" port feeds this power at speeds of 30-800 mm/s.
No. The adjustable 29mm air cushions only decelerate the piston near stroke end. If air is lost, the load drifts. You must add an external rod lock or pilot-operated check valve for secure load holding.
