Airtac SAUD Double Rod Cylinder SAUD100X70S
The AirTAC Airtac SAUD Double Rod Cylinder SAUD100X70S is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 70mm 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 SAUD100X70S
The AirTAC SAUD100X70S is a double-acting, double-rod profile cylinder. A piston rod protrudes from both ends, meaning both faces use the rod-side area. This yields exactly 3681 N of thrust and pull 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.
Because the rear rod extends out the back, it provides a perfect cam for CMSG, DMSG, or EMSG switches since this SKU includes the -S magnet. Operating speed runs 30-800 mm/s on a 1/2 inch port.

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 SAUD100X70S Is Used
Twin-Spindle Machining
Drives two synchronized machining heads from one piston, using the equal 3681 N force to push and pull both tools simultaneously without rotational twist.
Dual Transfer Arms
Powers opposing transfer arms on a packaging line, utilizing the back rod extension to trip a reed switch and confirm stroke completion.
Is the Airtac SAUD Double Rod Cylinder SAUD100X70S the Right Cylinder?
Choose this 100 mm bore if your task demands equal 3681 N force in both directions. Stepping down, the 80 mm bore provides 2268 N each way. Stepping up is not possible as 100 mm is the largest in the series. The twin rods prevent twist during travel, making it ideal for synchronized twin-tool setups or carrying a sensor cam on the back end. Mounting is limited to Basic, FA flange, and LB foot brackets that match the AirTAC SC series. At a 70 mm stroke, side loading is minimal, but always guide the load externally on longer strokes. Note that air cushions only decelerate the piston; you must add an external rod lock or pilot-operated check valve to hold a load securely without live air.
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 SAUD100X70S FAQ
The force is equal in both directions because a rod exits both ends. It outputs 3681 N at 0.5 MPa, 5153 N at 0.7 MPa, and 6626 N at 0.9 MPa. The 1/2 inch port and 29 mm adjustable cushions handle the 30-800 mm/s speed range.
The twin rods provide anti-rotation guidance for non-twisting movements and can drive two tools at once. The -S option adds a piston magnet, letting you mount CMSG, DMSG, or EMSG sensors directly on the profile barrel or use the rear rod as a switch cam.
