About the Airtac SAU Standard Air Cylinder SAU100X270
The AirTAC SAU100X270 is a double-acting profile-type cylinder engineered for heavy-duty automation. Featuring an extruded aluminum barrel, it provides a significant space advantage by being shorter than an ISO 15552 cylinder of the same bore. It delivers a robust 3927 N of push force at 0.5 MPa, making it suitable for demanding industrial environments.
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. In a vertical lift scenario, this translates to lifting about 200 kg with a 2:1 safety margin. This unit utilizes a 1/2 inch air port and a 29 mm adjustable air cushion at both ends. Since this SKU lacks the -S magnet option, it cannot accept CMSG, DMSG, or EMSG magnetic switches.

Where the Airtac SAU Standard Air Cylinder SAU100X270 Is Used
Heavy Stamping Press
Drives heavy tooling dies in an automotive stamping line, utilizing the 3927 N push force to form thick steel components reliably.
Pallet Dispenser
Pushes empty or loaded wooden pallets into a high-speed packaging conveyor, where the 270 mm stroke provides the exact reach needed.
Injection Molding Extraction
Actuates a robust mechanical arm to extract heavy molded plastic parts from a large injection molding machine.
Is the Airtac SAU Standard Air Cylinder SAU100X270 the Right Cylinder?
When sizing this 100 mm bore model, evaluate your force needs carefully. If your application requires less power, the 80 mm bore offers 2513 N of push force at 0.5 MPa. Conversely, if 3927 N is insufficient, you would need to explore multi-cylinder setups or larger custom actuators, as 100 mm is the largest standard SAU bore. For mounting, this cylinder shares full compatibility with AirTAC SC-series accessories, including LB foot brackets, FA/FB flanges, and CA/CB clevises.
Keep in mind that a standard double-acting cylinder does not hold its position if air pressure is lost or the valve is centered; the piston will drift. The integrated air cushion merely decelerates the piston near the end of the stroke and does not function as a locking brake. To suspend a load safely, install an external rod lock or a pilot-operated check valve.
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 SAU100X270 FAQ
The SAU100X270 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 at 0.9 MPa it is 7068 N. The theoretical maximum force is 801 kgf at 1.0 MPa. It features a 1/2 inch port, a 29 mm adjustable air cushion, and operates at speeds between 30-800 mm/s.
No, the SAU is a compact profile cylinder and is not dimensionally interchangeable with ISO 15552 standards. However, it shares identical mounting dimensions with the AirTAC SC series, allowing you to use SC-series LB foot, FA/FB flange, and CA/CB clevis brackets. Additionally, because this specific SKU lacks the -S magnet, it cannot support magnetic position sensors.
