Airtac SAUD Double Rod Cylinder SAUD100X20S
The AirTAC Airtac SAUD Double Rod Cylinder SAUD100X20S is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 20mm 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 SAUD100X20S
The AirTAC SAUD100X20S is a double-acting, double-rod profile cylinder. A rod protrudes from both ends, meaning the push and pull output is identical at 3681 N each way at 0.5 MPa. The extruded aluminium barrel keeps the unit shorter than an ISO 15552 cylinder of the same bore, and the 1/2 inch port feeds the 100 mm bore.
Because this SKU includes the -S magnet, it directly supports CMSG, DMSG and EMSG switches for end-of-stroke detection. The twin rods provide rigid anti-rotation guidance and let you mount a sensor cam on the back rod.

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 SAUD100X20S Is Used
Twin-Spindle Machining
Drives two synchronized machining heads from one piston, using the equal both-ways force to maintain balanced cutting feed on both ends.
Dual Transfer Pushers
Mounts a pusher tool on the front rod and a switch cam on the back rod to time part movement on a conveyor line without torsional deflection.
Is the Airtac SAUD Double Rod Cylinder SAUD100X20S the Right Cylinder?
Choose this 100 mm bore delivering 3681 N equal force if your application requires strict non-rotating accuracy or twin tooling driven from one piston. Sizing down, the 80 mm bore provides 2268 N both ways, while if you need less force the 63 mm bore offers 1402 N. Mounting is limited to Basic, FA flange and LB foot options, matching the AirTAC SC series. The -S magnet is essential if you need position sensing. With a short 20 mm stroke, side-load stress is minimal, but always support external guide rods for any heavy off-center loads.
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 SAUD100X20S FAQ
The force is equal in both directions because a 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 inch port supplies air to achieve these figures.
No, a plain cylinder drifts without live air, as the adjustable 29 mm cushion only decelerates near stroke end. For a locked load, install an external rod lock or pilot-operated check valve. The -S magnet works with CMSG, DMSG and EMSG sensors.
