Airtac SAUD Double Rod Cylinder SAUD100X850S
The AirTAC Airtac SAUD Double Rod Cylinder SAUD100X850S is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 850mm 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 SAUD100X850S
The AirTAC SAUD100X850S is a double-acting, double-rod profile cylinder. A 25mm rod exits both ends, meaning push and pull forces are identical at 3681 N each way at 0.5 MPa. The extruded aluminium barrel keeps the body shorter than an ISO 15552 cylinder of the same bore. This unit includes a 1/2 inch port and an M20x1.5 rod thread.
Because the rod protrudes at the back, you can mount a switch cam directly on it for end-of-stroke signaling. The -S suffix means a piston magnet is built-in, ready for CMSG, DMSG or EMSG sensors.

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 SAUD100X850S Is Used
Synchronized Transfer
Drives dual pusher arms simultaneously from both rod ends to move heavy pallets without twisting.
Twin-Spindle Machining
Operates two matching cutting tools in parallel, ensuring perfectly matched feed rates via one piston.
Is the Airtac SAUD Double Rod Cylinder SAUD100X850S the Right Cylinder?
Choose this 100mm bore if your application needs high equal force in both directions. If you need less thrust, the 80mm bore provides 2268 N each way at 0.5 MPa; if you need more, confirm from datasheet for larger custom setups. The double-rod design 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. With an 850mm stroke, external guides are strongly recommended to prevent rod bending and absorb side loads. A Viton H seal option raises the operating temperature to 0-150 C.
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 SAUD100X850S FAQ
Force is equal in both directions because rods exit both ends. It delivers 3681 N at 0.5 MPa, 5153 N at 0.7 MPa, and 6626 N at 0.9 MPa. The 1/2 inch port feeds both chambers equally.
No, the air cushion only decelerates the piston near the stroke end; it does not act as a brake. For load holding on air loss, you must fit an external rod lock or a pilot-operated check valve.
