Airtac SAU Standard Air Cylinder SAU100X180S
The AirTAC Airtac SAU Standard Air Cylinder SAU100X180S is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 180mm 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 SAU100X180S
The AirTAC SAU100X180S is a double-acting profile-type cylinder engineered for heavy-duty tasks, delivering a push force of 3927 N at 0.5 MPa. Its extruded aluminum barrel with a built-in sensor groove makes it shorter and more compact than a standard ISO 15552 cylinder of the same bore, saving valuable machine space without sacrificing power. The unit operates on a 1/2" air port and features a 25 mm carbon steel rod with an M20x1.5 thread.
Because this SKU includes the -S magnet, it readily supports CMSG, DMSG, or EMSG electronic switches for precise position detection. For practical sizing, plan for a safe working load of roughly 2356 N—about 60% of the 0.5 MPa push figure—to account for seal friction and smooth travel. Alternatively, you can expect it to lift about 200 kg vertically with a safe 2:1 margin. If your environment exceeds standard limits, a Viton H seal option extends the operating temperature range up to 150 C.

Where the Airtac SAU Standard Air Cylinder SAU100X180S Is Used
Heavy Stamping Press
Drives a 150 kg upper die set in an automotive parts stamping line, utilizing the 3927 N push force to shear thick steel blanks reliably.
Pallet Dispenser
Pushes empty wooden pallets into a packaging conveyor lane, where the 180 mm stroke provides the exact travel needed to index one unit at a time.
Vertical Lift Gate
Actuates a 200 kg material lift gate in a logistics hub, taking advantage of the compact profile length to fit within tight structural supports.
Is the Airtac SAU Standard Air Cylinder SAU100X180S the Right Cylinder?
When sizing this model, compare it against adjacent bores to match your exact requirements. Stepping down to a bore 63 yields 1559 N of push at 0.5 MPa, while stepping up is not available as 100 mm is the largest in the SAU family. This 180 mm stroke falls well within the 1500 mm maximum, keeping the assembly rigid. Remember that a standard SAU does not maintain its position if air pressure drops or the valve is centered; the piston will drift, and the adjustable 29 mm air cushions only decelerate the rod near the stroke ends rather than locking it. For suspended loads, install an external rod lock or a pilot-operated check valve.
This cylinder shares its mounting footprint with AirTAC SC-series accessories, allowing you to use standard LB foot brackets, FA/FB flanges, or CA/CB clevises. You can also utilize I, Y, floating (F), or universal (U) rod knuckles to adapt the M20x1.5 rod end to your mechanics. The integrated -S magnet ensures you can easily mount reed or solid-state sensors directly into the profile barrel groove without needing extra hardware.

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 SAU100X180S FAQ
At 0.5 MPa, the push force is 3927 N and the pull force is 3681 N. At 0.7 MPa it pushes 5497 N, and at 0.9 MPa it pushes 7068 N. The theoretical maximum force is 801 kgf at 1.0 MPa. The operating pressure range is 0.15-1.0 MPa, the proof pressure is 1.5 MPa, and the speed range is 30-800 mm/s.
It is not an ISO 15552 cylinder, but it is shorter and more compact than one. Mounting compatibility is strictly with the AirTAC SC series accessories, such as LB foot, FA/FB flange, and CA/CB clevis brackets. Because this model includes the -S magnet, you can install CMSG, DMSG, or EMSG sensors directly into the profile barrel groove.
