Airtac SAU Standard Air Cylinder SAU100X280
The AirTAC Airtac SAU Standard Air Cylinder SAU100X280 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 SAU100X280
The AirTAC SAU100X280 is a double-acting profile-type cylinder engineered to deliver massive thrust in a footprint noticeably shorter than a same-bore ISO 15552 unit. It pushes with 3927 N and pulls with 3681 N at 0.5 MPa, utilizing a 1/2 inch port and a 25 mm carbon steel rod. The extruded aluminum barrel integrates adjustable air cushions at both ends to tame heavy end-of-stroke impacts.
For real-world sizing, plan for a safe working load of roughly 2356 N, which accounts for seal friction at 0.5 MPa. Vertically, this translates to lifting about 200 kg with a 2:1 safety margin. Because this specific SKU lacks the -S magnet, it cannot host CMSG, DMSG, or EMSG sensors. If your environment exceeds the standard -20 to +70 C range, you can specify the Viton H high-temperature seal option for up to 150 C.

Where the Airtac SAU Standard Air Cylinder SAU100X280 Is Used
Injection Mold Clamping
Provides the heavy 3927 N push force required to secure large injection mold halves, leveraging the compact profile to fit within tight press enclosures.
Palletizing Head Actuator
Drives a 280 mm stroke to lift and position heavy palletized goods, where the 200 kg vertical lift capacity handles substantial packaging weights smoothly.
Heavy Press Ejection
Ejects dense stamped metal parts from a hydraulic press, using the 29 mm adjustable air cushions to absorb the substantial kinetic energy generated during retraction.
Is the Airtac SAU Standard Air Cylinder SAU100X280 the Right Cylinder?
This 100 mm bore sits at the top of the SAU range; if 3927 N at 0.5 MPa is excessive, step down to the 80 mm bore (2513 N push). As the largest option, there is no larger standard SAU to scale up to. You can mount this unit using AirTAC SC-series accessories like LB foot brackets, FA/FB flanges, or CA/CB clevises. At 280 mm of travel, side-load risks are moderate, so ensure your rod-end knuckle (I, Y, F, or U) is aligned precisely to prevent rod bending.
Remember that the integrated air cushion solely decelerates the piston near the stroke ends and never acts as a braking lock. If a power loss or centered valve drops your air supply, the piston will drift. To suspend a load safely during an outage, install an external rod lock or a pilot-operated check valve in 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 SAU100X280 FAQ
The 100 mm bore features a 1/2 inch port and 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.
It is strictly compatible with AirTAC SC-series mounting accessories, not ISO 15552 parts, despite its compact dimensions. Additionally, because this SKU lacks the -S magnet, it cannot support CMSG, DMSG, or EMSG magnetic sensors.
