Airtac SAU Standard Air Cylinder SAU100X225
The AirTAC Airtac SAU Standard Air Cylinder SAU100X225 is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 225mm 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 SAU Standard Air Cylinder SAU100X225
The AirTAC SAU100X225 is a double-acting profile-type cylinder engineered for heavy-duty automation. Featuring an extruded aluminum barrel, it provides a 225 mm stroke and operates at 30-800 mm/s. Because it is a non-standard made-to-order stroke, it is tailored for specific machinery layouts. It delivers a robust 3927 N push force at 0.5 MPa, utilizing a 1/2" air port and an M20x1.5 rod thread.
This model is significantly shorter than an ISO 15552 cylinder of the same bore, offering a distinct space advantage in tight machine frames. For practical sizing, plan for a safe working load of roughly 2356 N, which accounts for seal friction and smooth travel at 0.5 MPa. For vertical applications, this translates to lifting about 200 kg safely with a 2:1 margin. The standard TPU seals handle -20 to +70 C, but a Viton H option extends heat resistance up to 150 C.

Where the Airtac SAU Standard Air Cylinder SAU100X225 Is Used
Heavy Press Ejection
Provides the robust 3927 N push force required to eject dense metal stampings from a hydraulic press bed in automotive part manufacturing.
Pallet Dispenser
Handles the reliable 225 mm stroke needed to separate and feed empty wooden pallets into an automated high-speed packaging line.
Injection Mold Clamping
Secures heavy mold halves during low-pressure clamping operations where a compact profile cylinder saves valuable floor space.
Is the Airtac SAU Standard Air Cylinder SAU100X225 the Right Cylinder?
When sizing this actuator, evaluate your force margins carefully. If your application requires less power, stepping down to the 80 mm bore yields 2513 N push at 0.5 MPa. Conversely, the 100 mm bore is the largest available in the SAU series, so for loads exceeding 3927 N you would need to split the motion across two cylinders or explore alternative heavy-duty series. This specific SKU lacks the -S magnet, meaning it cannot accept CMSG, DMSG, or EMSG magnetic switches for position sensing.
Because the 225 mm stroke is a non-standard made-to-order length, ensure your mounting setup perfectly accommodates it. You can utilize AirTAC SC-series accessories, such as LB foot mounts or FA flanges, for secure installation. Remember that a standard cylinder does not hold its load if air pressure drops; the adjustable air cushions only decelerate the piston near the end of travel. To prevent drifting, integrate an external rod lock or a pilot-operated check valve into your pneumatic circuit.
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 SAU Standard Air Cylinder SAU100X225 FAQ
The SAU100X225 features a 1/2" air port and an M20x1.5 rod thread. It delivers a push force of 3927 N and a pull force of 3681 N at 0.5 MPa. At 0.7 MPa, the push force is 5497 N, and the theoretical maximum force is 801 kgf at 1.0 MPa.
No, this specific SKU does not include the -S magnet option. Without the internal magnet, it cannot accommodate CMSG, DMSG, or EMSG magnetic switches. You will need to use external mechanical limit switches for position feedback.
