Airtac SAU Standard Air Cylinder SAU100X90
The AirTAC Airtac SAU Standard Air Cylinder SAU100X90 is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 90mm 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 SAU100X90
The AirTAC SAU100X90 is a double-acting profile-type cylinder engineered for heavy-duty automation. It delivers a push force of 3927 N and a pull force of 3681 N at 0.5 MPa. Its extruded aluminum barrel with a 1/2 inch port and M20x1.5 rod thread makes it significantly shorter than an ISO 15552 cylinder of the same bore, providing a space-saving footprint for tight machine envelopes.
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. This equates to lifting about 200 kg vertically with a 2:1 safety margin. The unit features a 29 mm adjustable air cushion at both ends to decelerate heavy masses. Since this specific SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG magnetic switches; if position feedback is required, an external sensor setup or a different model must be selected.

Where the Airtac SAU Standard Air Cylinder SAU100X90 Is Used
Heavy Stamping Press
Drives a 150 kg die set in a compact metal forming press, utilizing the 3927 N push force at 0.5 MPa to shape thick gauge steel components reliably.
Pallet Dispenser
Pushes heavy wooden pallets into an automated packaging line, where the shorter profile barrel saves critical floor space in congested logistics hubs.
Injection Mold Clamp
Secures and actuates a heavy mold halve within a plastics facility, taking advantage of the 29 mm adjustable air cushions to soften the end-of-stroke impact.
Is the Airtac SAU Standard Air Cylinder SAU100X90 the Right Cylinder?
When sizing this 100 mm bore actuator, compare it against neighboring bores to match your exact load requirements. Stepping down to an 80 mm bore reduces the 0.5 MPa push force to 2513 N, while this 100 mm unit provides 3927 N, making it the top choice for high-thrust tasks within the standard series. If you need even more power, you will exceed the standard SAU range and must explore larger custom actuators. The 90 mm stroke keeps the overall length highly compact, minimizing rod-bending concerns, but always ensure the load is guided to prevent side loads. Mounting is straightforward using AirTAC SC-series accessories like LB foot, FA/FB flange, or CA/CB clevis brackets. Remember that a plain cylinder drifts when air is lost or the valve is centered; the air cushion only decelerates the piston near stroke end and does not act as a brake. For securing a vertical load, integrate 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 SAU100X90 FAQ
The SAU100X90 features a 1/2 inch air port and generates 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 it reaches a theoretical maximum of 801 kgf at 1.0 MPa.
No, the SAU is a profile-type cylinder that is shorter than an ISO 15552 unit and is not dimensionally interchangeable with ISO standards; it shares mounting accessories only with the AirTAC SC series (LB, FA/FB, CA/CB). Additionally, this specific SKU lacks a magnet, so it cannot accept CMSG, DMSG, or EMSG magnetic switches.
