Airtac SAU Standard Air Cylinder SAU100X325
The AirTAC Airtac SAU Standard Air Cylinder SAU100X325 is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 325mm 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 SAU100X325
The AirTAC SAU100X325 is a double-acting profile-type cylinder engineered for heavy-duty automation. It utilizes an extruded aluminum barrel with an integrated sensor groove, making it significantly shorter and more compact than an ISO 15552 cylinder of the same bore. Operating at 0.15-1.0 MPa, this unit delivers a robust 3927 N of push force and 3681 N of pull force at 0.5 MPa, scaling up to a theoretical maximum of 801 kgf at 1.0 MPa.
For practical sizing, plan for a safe working load of about 2356 N, which accounts for seal friction and smooth travel at 0.5 MPa. In vertical lift scenarios, this translates to lifting about 200 kg safely with a 2:1 margin. The 1/2" port and M20x1.5 rod thread handle high flow rates, while the 29 mm adjustable air cushions at both ends decelerate the heavy 25 mm rod smoothly. Note that this specific SKU lacks the -S magnet, meaning it cannot support CMSG, DMSG, or EMSG magnetic switches.

Where the Airtac SAU Standard Air Cylinder SAU100X325 Is Used
Heavy Stamping Presses
Provides the high 3927 N push force required to actuate heavy stamping dies, utilizing its 325 mm stroke to clear large tooling during part ejection.
Pallet Transfer Stops
Acts as a robust stopper block on high-mass pallet conveyors, where the compact profile saves valuable floor space without sacrificing the 801 kgf maximum theoretical holding strength.
Automated Crate Lifts
Raises loaded timber crates vertically, safely lifting up to 200 kg loads when properly guided on external rails to prevent rod deflection over the 325 mm extension.
Is the Airtac SAU Standard Air Cylinder SAU100X325 the Right Cylinder?
When sizing this 100 mm bore model, consider the neighboring bores: stepping down to an 80 mm cylinder reduces the 0.5 MPa push force to 2513 N, while no larger standard bore exists in the SAU series. Because this SKU lacks the -S suffix, it cannot accept position sensors; if detection is required, select an SAU100X325-S model instead. Mounting is highly flexible using AirTAC SC-series accessories, including LB foot blocks, FA/FB flanges, CA/CB clevises, or I/Y/F/U rod knuckles. For high-temperature environments up to 150 C, specify the Viton H seal option instead of the standard TPU.
With a 325 mm stroke, the 25 mm rod is susceptible to bending under lateral stress. Always use external guide rails to support the load and prevent side-loading. Furthermore, a standard double-acting cylinder does not hold its position if air pressure drops or the valve is centered—the piston will drift. The air cushion only decelerates the piston near the end of the stroke and acts purely as a dampener, never as a locking mechanism. To maintain a vertical 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 SAU100X325 FAQ
The SAU100X325 features a 1/2 inch air port and an M20x1.5 rod thread. It generates 3927 N push and 3681 N pull at 0.5 MPa, 5497 N push at 0.7 MPa, 7068 N push at 0.9 MPa, and a theoretical maximum of 801 kgf at 1.0 MPa.
It shares mounting dimensions only with AirTAC SC-series accessories (LB, FA, FB, CA, CB), not ISO 15552 brackets. Additionally, because this specific SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG magnetic sensors.
