Airtac SAUD Double Rod Cylinder SAUD100X125S
The AirTAC SAUD Double Rod Cylinder SAUD100X125S is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 125mm 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 SAUD100X125S
The AirTAC SAUD100X125S is a double-acting, double-rod profile cylinder. A 25mm rod exits both ends of the hard-anodized extruded aluminum barrel, meaning both faces use the rod-side piston area. This yields exactly 3681 N of thrust and pull at 0.5 MPa, with the 1/2" port supplying ample airflow. The extruded profile makes it shorter than an ISO 15552 cylinder of the same bore.
Because the rod protrudes at the rear, you can mount a switch cam directly on it for CMSG or DMSG sensors. The built-in magnet (-S) enables electronic position tracking. A Viton H seal can raise the operating ceiling to 150 C.

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 SAUD100X125S Is Used
Twin-Spindle Machining
Drives two synchronized machining heads from one piston, ensuring perfectly balanced cutting forces without torsional twist.
Dual Transfer Arms
Powers opposing pick-off arms that grip and transfer heavy cartons simultaneously from both sides.
Guided Pressing Station
Applies 3681 N of equal downward and upward force for pressing bearings, using the dual rods to prevent platen rotation.
Is the Airtac SAUD Double Rod Cylinder SAUD100X125S the Right Cylinder?
Choose this 100mm bore when you need 3681 N of equal push and pull force at 0.5 MPa. If your project requires less thrust, step down to the 80mm bore delivering 2268 N both ways. If you need more, there is no larger standard SAUD bore. The double-rod architecture is ideal for anti-rotation guidance, driving twin tooling, or rear-cam sensing. Mounting is limited to Basic, FA flange, and LB foot styles compatible with the AirTAC SC series. The -S magnet supports CMSG, DMSG, and EMSG switches. For this 125mm stroke, side loads are manageable, but always use external guide rails for any stroke exceeding 300mm to prevent binding.
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 SAUD100X125S FAQ
Because the 25mm rod exits both ends, the force is equal in both directions: 3681 N at 0.5 MPa, 5153 N at 0.7 MPa, and 6626 N at 0.9 MPa. It never produces a larger single-rod push value.
No, a plain cylinder drifts without live air; the adjustable 29mm cushions only decelerate near stroke end. For a locked load, install an external rod lock or pilot-operated check valve.
