Airtac SAUD Double Rod Cylinder SAUD100X185S
The AirTAC Airtac SAUD Double Rod Cylinder SAUD100X185S is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 185mm 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 SAUD100X185S
The AirTAC SAUD100X185S is a double-acting, double-rod profile cylinder. A 25mm rod exits both ends of the hard-anodized aluminum barrel, meaning both faces use the rod-side area. This yields exactly 3681 N of thrust and pull at 0.5 MPa. The extruded profile is notably shorter than an ISO 15552 cylinder of the same 100mm bore.
Because the rear rod protrudes, it easily carries a switch cam for position sensing. This unit includes the -S 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 SAUD100X185S Is Used
Twin-Spindle Machining
Drives two synchronized machining heads from one piston, ensuring perfectly balanced cutting forces without torsional deflection.
Dual Transfer Pushers
Pushes parallel conveyor lanes simultaneously using both rod ends, maintaining precise timing across a wide packaging line.
Guided Lift Stations
Lifts heavy platens with inherent anti-rotation resistance from the dual rods, preventing platform twist during vertical actuation.
Is the Airtac SAUD Double Rod Cylinder SAUD100X185S the Right Cylinder?
Choose this 100mm bore when your application requires 3681 N of equal force in both directions. If you need less power, step down to the 80mm bore which provides 2268 N both ways. If you require more, no larger standard SAUD bore exists, so you would need twin cylinders. The double-rod architecture is ideal for anti-rotation guidance, driving twin tooling, or back-end sensing. Mounting is limited to Basic, FA flange, and LB foot styles, matching the AirTAC SC series. At a 185mm stroke, side loads are manageable, but always use external guide rails for any stroke over 300mm. A plain cylinder drifts on air loss, so specify an external rod lock for load holding.
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 SAUD100X185S FAQ
The force is equal in both directions due to the double-rod design. It provides 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 29mm cushion ensure smooth operation.
The protruding rear rod provides equal push and pull forces, prevents piston rotation, and offers a convenient surface to mount a switch cam. This -S model includes a magnet for CMSG, DMSG, or EMSG sensors.
