Airtac SAUD Double Rod Cylinder SAUD100X325S
The AirTAC Airtac SAUD Double Rod Cylinder SAUD100X325S is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 325mm 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 SAUD100X325S
The AirTAC SAUD100X325S is a double-acting, double-rod profile cylinder. A rod protrudes from both ends, meaning both faces use the rod-side area. This yields equal push and pull force of 3681 N each way at 0.5 MPa. The extruded hard-anodized aluminum barrel makes it shorter than an ISO 15552 cylinder of the same bore.
This unit includes a piston magnet for CMSG, DMSG, or EMSG switches. With a 325 mm stroke, you must use external guides to prevent rod bending under side loads. The 1/2" port and M20x1.5 rod thread handle high flow.

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 SAUD100X325S Is Used
Twin-Spindle Machining
Drives two synchronized machining heads from one piston, ensuring perfectly balanced cutting feed rates without torsional twist.
Dual-Belt Transfer
Shifts parallel conveyor lanes simultaneously using the dual rod outputs, maintaining precise product spacing during high-speed transfers.
Balanced Vertical Lift
Lifts heavy platens straight up and down with equal force both ways, using the back rod to trigger a descent limit switch.
Is the Airtac SAUD Double Rod Cylinder SAUD100X325S the Right Cylinder?
Select 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, confirm the maximum bore limits for your setup. A double rod is the right call for anti-rotation guidance, driving twin tooling, or mounting a switch cam on the back rod. Mounting is limited to Basic, FA flange, and LB foot styles, matching the AirTAC SC series. Because the stroke is 325 mm, external load guides are required to manage side loads and prevent rod bending.
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 SAUD100X325S FAQ
Because it is a double-rod cylinder, the force is equal in both directions. It outputs 3681 N at 0.5 MPa, 5153 N at 0.7 MPa, and 6626 N at 0.9 MPa. The 1/2" port supplies the air required for this 100 mm bore.
No. The air cushions only decelerate the piston near the stroke ends; they do not lock the load. If air is lost, the piston drifts. For a held vertical load, you must add an external rod lock or a pilot-operated check valve.
