Airtac SAUD Double Rod Cylinder SAUD100X250
The AirTAC Airtac SAUD Double Rod Cylinder SAUD100X250 is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 250mm 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 SAUD100X250
The AirTAC SAUD100X250 is a double-acting, double-rod profile cylinder. A Ø25 mm piston rod exits both ends, meaning both faces use the rod-side area and the push and pull force is equal at 3681 N each way at 0.5 MPa. The extruded aluminium barrel is shorter than an equivalent bore ISO 15552 unit. This model features a 1/2 inch port, M20x1.5 rod thread, and 29 mm adjustable air cushions at both ends.
Because the rod protrudes at the rear, you can mount a sensor cam or trip a switch directly on the back side, though this specific SKU lacks a magnet and cannot take a magnetic switch. The symmetrical twin-rod design provides excellent anti-rotation guidance for synchronized tooling.

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 SAUD100X250 Is Used
Twin-Spindle Drilling
Drives two synchronized machining spindles from one piston, ensuring parallel hole alignment without torsional deflection.
Dual Pneumatic Diverter
Actuates opposing guide gates simultaneously on a sorting line, using the equal bidirectional force to recenter packages.
Symmetric Lift Platform
Raises and lowers a small palletizing platform with equal push and pull thrust, relying on the anti-rotation properties of both rods.
Is the Airtac SAUD Double Rod Cylinder SAUD100X250 the Right Cylinder?
When sizing this 100 mm bore unit, consider the neighbouring 80 mm option if you need less force (2268 N at 0.5 MPa) or step up if you require more, though 100 mm is the largest standard SAUD bore offering 3681 N. A double-rod configuration is the right call when your application demands non-rotating anti-twist guidance, twin-tool driving, or back-end sensing. Mounting is limited to Basic, FA flange, and LB foot styles, matching the AirTAC SC series. For this 250 mm stroke, ensure external load guides are used to prevent side-load binding. Note this non-magnetic version cannot accept CMSG or DMSG switches.
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 SAUD100X250 FAQ
The force is equal in both directions because the rod exits both ends. It generates 3681 N at 0.5 MPa, 5153 N at 0.7 MPa, and 6626 N at 0.9 MPa. The 1/2 inch port supplies air to both chambers equally.
No, a plain double-rod cylinder drifts on air loss or when the valve is centered; the 29 mm adjustable cushions only decelerate near stroke end and do not act as a brake. Use an external rod lock or pilot-operated check valve for secure load holding.
