Airtac SAU Standard Air Cylinder SAU100X280S
The AirTAC Airtac SAU Standard Air Cylinder SAU100X280S is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 280mm 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 SAU100X280S
The AirTAC SAU100X280S is a double-acting profile-type cylinder engineered for heavy-duty tasks. It delivers a push force of 3927 N and a pull force of 3681 N at 0.5 MPa. Because it uses an extruded aluminum barrel rather than a bulky standard design, this 100 mm bore unit is noticeably shorter than an ISO 15552 cylinder, saving valuable machine space. It features a 1/2" port and an M20x1.5 rod thread.
For practical sizing, plan for a safe working load of about 2356 N, which accounts for seal friction at 0.5 MPa. In vertical lifting applications, this translates to lifting roughly 200 kg with a 2:1 safety margin. The -S suffix indicates a built-in piston magnet, allowing you to mount CMSG, DMSG, or EMSG sensors directly into the barrel groove for precise position detection.

Where the Airtac SAU Standard Air Cylinder SAU100X280S Is Used
Press Tool Ejection
Provides the robust 3927 N push force needed to eject heavy formed metal parts from a hydraulic press bed, while the compact profile minimizes interference with the press frame.
Pallet Stopper Gate
Acts as a heavy-duty stopper arm on a high-throughput packaging conveyor, securely halting loaded pallets. The 280 mm stroke provides ample clearance for varying pallet widths.
Injection Mold Separation
Delivers consistent pulling force to separate large injection molding halves, utilizing the 3681 N pull capacity at 0.5 MPa to safely extract heavy mold components.
Is the Airtac SAU Standard Air Cylinder SAU100X280S the Right Cylinder?
When sizing this actuator, compare it to adjacent bores: a 63 mm bore provides 1559 N push at 0.5 MPa, while an 80 mm bore yields 2513 N. If your application requires more power than the 100 mm bore's 3927 N, you will need to explore larger custom actuators, as 100 mm is the largest standard SAU size. Mounting is straightforward using AirTAC SC-series accessories, including LB foot brackets, FA/FB flanges, and CA/CB clevises.
Remember that the adjustable air cushions at both ends only decelerate the piston near the stroke limits; they do not function as a brake. If your machine loses air pressure or the valve is centered, the rod will drift. To maintain a vertical load safely under these conditions, 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 SAU100X280S FAQ
At 0.5 MPa, the push force is 3927 N and the pull force is 3681 N. At 0.7 MPa, the push force is 5497 N, and at 0.9 MPa it reaches 7068 N. The theoretical maximum force is 801 kgf at 1.0 MPa. Operating pressure ranges from 0.15-1.0 MPa, with a proof pressure of 1.5 MPa. The speed range is 30-800 mm/s.
You cannot use ISO 15552 brackets, as the SAU profile cylinder is more compact and has a distinct footprint. Mounting accessories must be from the AirTAC SC series, such as LB foot, FA/FB flange, or CA/CB clevis mounts. However, the -S magnet allows you to use CMSG, DMSG, or EMSG sensors in the integrated barrel groove.
