Airtac SAUD Double Rod Cylinder SAUD100X25S
The AirTAC Airtac SAUD Double Rod Cylinder SAUD100X25S is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 25mm 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 SAUD100X25S
The AirTAC SAUD100X25S is a double-acting, double-rod profile cylinder. A 25mm rod exits both ends of the hard-anodized aluminum extruded barrel, meaning both faces use the identical rod-side piston area. This yields an equal push and pull force of 3681N at 0.5MPa. The extruded profile keeps the unit shorter than an ISO 15552 cylinder of the same bore, and mounting parts match the AirTAC SC series.
Because the -S suffix denotes a built-in piston magnet, this model directly accepts CMSG, DMSG, or EMSG electronic or reed switches. The 1/2 inch port feeds the 100mm bore for speeds of 30-800mm/s. A high-temperature Viton H seal option can extend operation from -20 to +150C.

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 SAUD100X25S Is Used
Twin-Spindle Machining
Drives two opposing machining heads simultaneously with identical 3681N force, ensuring perfectly synchronized part finishing.
Anti-Rotate Transfer
Uses the dual rods to prevent mechanical twist during short-stroke part ejection on a high-speed packaging line.
Rear-Cam Sensing
Mounts a DMSG reed switch directly on the back rod to confirm end-of-stroke position in a confined machinery cell.
Is the Airtac SAUD Double Rod Cylinder SAUD100X25S the Right Cylinder?
Choose this 100mm bore when your application demands equal 3681N force in both directions, such as driving twin tooling or preventing rotation without external guides. If you need less force, the neighboring 80mm bore delivers 2268N each way; if you need more, this is the largest standard SAUD bore available. The short 25mm stroke keeps the assembly highly compact, and the -S magnet allows back-end switch mounting on the rear rod. Mounting is limited to Basic, FA flange, or LB foot styles. Note that a plain pneumatic cylinder cannot hold a load without live air; the 29mm adjustable cushions only decelerate near the stroke ends. For suspended loads, install 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 SAUD100X25S FAQ
The force is equal in both directions because both faces have a rod. It outputs 3681N at 0.5MPa, 5153N at 0.7MPa, and 6626N at 0.9MPa. The cylinder features a 1/2 inch port and a 25mm piston rod.
The S indicates a built-in piston magnet. This allows you to mount CMSG, DMSG, or EMSG sensors anywhere along the extruded profile barrel, including on the back rod, for precise position detection.
