Airtac SAUD Double Rod Cylinder SAUD100X140S
The AirTAC SAUD Double Rod Cylinder SAUD100X140S is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 140mm 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 SAUD100X140S
The AirTAC SAUD100X140S is a double-acting, double-rod profile cylinder. A Ø25 mm rod exits both ends of the hard-anodized extruded aluminum barrel, meaning both faces use the identical rod-side area. This yields an equal output of 3681 N each way at 0.5 MPa. The 1/2" port and M20x1.5 rod thread handle high flow, while the 29 mm adjustable air cushions absorb end-of-stroke impact.
Because the body is a profile extrusion rather than a standard format, it is noticeably shorter than an ISO 15552 cylinder of the same 100 mm bore. The -S suffix indicates a built-in piston magnet for CMSG, DMSG or EMSG switches.

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 SAUD100X140S Is Used
Twin-Spindle Machining
Drives two synchronized machining heads from one piston, ensuring perfectly matched feed rates on both faces.
Dual-Action Transfer
Pushes a workpiece forward on the extend stroke and retracts a second fixture simultaneously for continuous flow.
Rear-Cam Sensing
Uses the protruding back rod to trip a CMSG or DMSG magnetic switch directly, freeing the front rod for tooling.
Is the Airtac SAUD Double Rod Cylinder SAUD100X140S the Right Cylinder?
Choose this 100 mm bore when your application demands 3681 N of thrust and retraction simultaneously, or when you need to mount a sensor cam on the back rod. If your load is lighter, the 80 mm bore offers 2268 N both ways; if you need more power, note that 100 mm is the largest available SAUD size. Mounting is limited to Basic, FA flange, and LB foot styles, matching the AirTAC SC series. At a 140 mm stroke, side loads are minimal, but always guide the load externally for longer travels. Remember that standard air cushions only decelerate the piston; they do not lock the load. For holding a load vertically without live air, add an external rod lock or pilot-operated check valve.
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 SAUD100X140S FAQ
The force is equal in both directions because the Ø25 mm rod exits both ends. It produces 3681 N at 0.5 MPa, 5153 N at 0.7 MPa, and 6626 N at 0.9 MPa on both extend and retract strokes.
The twin-rod design prevents rotation and provides identical force both ways, making it ideal for synchronized twin tooling. The extruded profile is shorter than an ISO 15552 cylinder, and the rear rod can carry a switch cam.
