Airtac SAU Standard Air Cylinder SAU100X30S
The AirTAC Airtac SAU Standard Air Cylinder SAU100X30S is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 30mm 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 SAU100X30S
The AirTAC SAU100X30S is a double-acting profile-type cylinder engineered for heavy-duty automation where space is at a premium. Its extruded aluminum barrel makes it shorter and more compact than an ISO 15552 cylinder of the same 100 mm bore, while sharing AirTAC SC-series mounting accessories. Operating at 0.15-1.0 MPa, it delivers a robust 3927 N push force at 0.5 MPa through a 1/2 inch port.
Because seal friction and smooth travel eat into theoretical ratings, plan for a safe working load of roughly 2356 N at 0.5 MPa. For vertical applications, this translates to lifting about 200 kg with a 2:1 safety margin. The -S suffix indicates a built-in piston magnet, allowing you to mount CMSG, DMSG, or EMSG switches directly into the profile groove for position sensing. If your environment exceeds the standard -20 to +70 C range, you can specify the Viton H high-temperature seal option to handle up to 150 C.

Where the Airtac SAU Standard Air Cylinder SAU100X30S Is Used
Heavy Stamp Press Feed
Provides the high 3927 N push force needed to clamp thick steel blanks in an automated stamping line, utilizing the short 30 mm stroke for rapid cycle times.
Palletized Load Lift
Lifts vertical loads of approximately 200 kg in packaging conveyors, benefiting from the compact profile length to fit within dense warehouse logistics machinery.
Injection Mold Ejection
Ejects dense plastic or metal molded parts from heavy tooling, relying on the 1/2 inch port for rapid air exhaustion and fast 30-800 mm/s operation.
Is the Airtac SAU Standard Air Cylinder SAU100X30S the Right Cylinder?
When sizing this 100 mm bore model, verify your force needs against its neighbors: the 80 mm bore provides 2513 N push at 0.5 MPa, while the 100 mm bore offers 3927 N. If you require even more power, larger custom solutions exist beyond this series. This SKU includes the -S magnet for electronic or reed sensors, and you can attach it using standard SC-series LB foot brackets, FA/FB flanges, or CA/CB clevises. Keep in mind that a standard cylinder does not hold its position if air pressure drops or the valve is centered; the piston will drift. The adjustable 29 mm air cushions only decelerate the piston near the end of stroke, so install an external rod lock or pilot-operated check valve if you need to secure a suspended load.
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 SAU100X30S FAQ
This 100 mm bore cylinder features a 1/2 inch port and a 25 mm rod. It delivers 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 is not an ISO 15552 cylinder, but it is shorter than one and uses AirTAC SC-series mounting accessories like LB, FA, and CA brackets. Because this model has the -S magnet, you can install CMSG, DMSG, or EMSG sensors directly into the barrel groove.
