Airtac SAUD Double Rod Cylinder SAUD100X85S
The AirTAC Airtac SAUD Double Rod Cylinder SAUD100X85S is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 85mm 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 SAUD100X85S
The AirTAC SAUD100X85S is a double-acting, double-rod profile cylinder. A rod protrudes from both ends, meaning both faces use the rod-side area and output force is identical in both directions. You get 3681 N each way at 0.5 MPa. The extruded aluminium barrel makes it shorter than an ISO 15552 cylinder of the same bore.
This 100 mm bore unit features a 1/2" port, M20x1.5 rod thread, and 29 mm adjustable cushions at both ends. The -S suffix denotes a built-in piston magnet for CMSG/DMSG/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 SAUD100X85S Is Used
Twin-Spindle Machining
Drives two synchronized machining heads from one piston, ensuring perfectly balanced cutting feed without rotational twist.
Dual Transfer Pushers
Pushes a workpiece from one belt to another using the front rod, while the back rod simultaneously retracts a diverter gate.
Balanced Lift Stations
Lifts heavy pallets vertically with equal force on the raise and lower strokes, using the back rod to trigger a limit switch.
Is the Airtac SAUD Double Rod Cylinder SAUD100X85S the Right Cylinder?
Choose this 100 mm bore when you need substantial equal force both ways. If you need less, the 80 mm bore provides 2268 N at 0.5 MPa. If you need more, this is the largest standard SAUD bore available. A double rod is the right call for anti-rotation guidance, driving twin tooling, or mounting a sensor cam on the back rod. Mounting is limited to Basic, FA flange, and LB foot types, matching the AirTAC SC series. At an 85 mm stroke, side loads are minimal, but always use external guides for longer reaches. The -S magnet allows electronic or reed switch placement anywhere along the profile.
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 SAUD100X85S FAQ
Because it is a double-rod cylinder, the force is equal both ways: 3681 N at 0.5 MPa, 5153 N at 0.7 MPa, and 6626 N at 0.9 MPa. The 1/2" port supplies air to both chambers equally.
No, a plain SAUD cylinder does not hold the load without live air. The adjustable 29 mm cushions only decelerate the piston near stroke end. For secure load holding, install an external rod lock or pilot-operated check valve.
