Airtac SAU Standard Air Cylinder SAU100X75S
The AirTAC Airtac SAU Standard Air Cylinder SAU100X75S is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 75mm 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 SAU100X75S
The AirTAC SAU100X75S is a double-acting profile-type cylinder engineered for heavy-duty automation. It delivers a robust 3927 N push and 3681 N pull at 0.5 MPa, utilizing a 1/2 inch air port and a 25 mm rod with an M20x1.5 thread. Its extruded aluminum barrel makes it more compact than a standard ISO 15552 unit of the same bore, saving valuable machine space without sacrificing power. The integrated -S piston magnet allows direct mounting of CMSG, DMSG, or EMSG switches along the built-in sensor groove.
For practical sizing, plan for a safe working load of about 2356 N, which accounts for seal friction at 0.5 MPa. In a vertical lift scenario, this translates to lifting roughly 200 kg with a 2:1 safety margin. If your environment exceeds standard thermal limits, specifying the Viton H seal option extends the operating range from -20 to +70 C up to 0-150 C for high-temperature processing equipment.

Where the Airtac SAU Standard Air Cylinder SAU100X75S Is Used
Heavy Stamp Press Feed
Pushes thick metal blanks into a stamping die using 3927 N of force at 0.5 MPa, with the 75 mm stroke ensuring rapid retraction for high-cycle production.
Pallet Lift Station
Raises loaded material pallets vertically, safely lifting approximately 200 kg of payload thanks to the robust 100 mm bore and integrated magnet for position confirmation.
Injection Mold Clamp
Secures heavy injection molding tooling halves in tight machine cells where the compact profile barrel saves floor space compared to traditional actuators.
Is the Airtac SAU Standard Air Cylinder SAU100X75S the Right Cylinder?
When sizing this 100 mm bore actuator, compare it against adjacent bores to ensure optimal performance: the 80 mm bore provides 2513 N push at 0.5 MPa, while this 100 mm bore reaches 3927 N. If you need even more force, note that 100 mm is the largest standard SAU bore, delivering a theoretical maximum of 801 kgf at 1.0 MPa. Because this is a double-acting cylinder, it will not hold a load if air pressure drops or the valve is centered; the piston will drift. You must add an external rod lock or a pilot-operated check valve for secure vertical positioning. The 75 mm stroke keeps the retracted length short, minimizing rod bending concerns, and mounting is fully compatible with AirTAC SC-series accessories like LB foot, FA flange, or CA clevis brackets.
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 SAU100X75S FAQ
This 100 mm bore model features a 1/2 inch air 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.
No, it is a compact profile cylinder that is shorter than an ISO 15552 unit, and it is not dimensionally interchangeable with ISO standards. However, it shares the exact same mounting accessories as the AirTAC SC series, including LB, FA, and CA brackets. The -S suffix means it includes a magnet for CMSG, DMSG, or EMSG sensors.
