Airtac SAU Standard Air Cylinder SAU100X145
The AirTAC Airtac SAU Standard Air Cylinder SAU100X145 is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 145mm 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 SAU100X145
The AirTAC SAU100X145 is a double-acting profile-type cylinder engineered to be shorter than an ISO 15552 unit of the same bore, granting a major space advantage in dense machinery layouts. It features a 100 mm bore, a 145 mm stroke, a Ø25 mm hard-chrome carbon steel rod, and a 1/2" air port. Operating at 0.15-1.0 MPa, it produces a push force of 3927 N and a pull force of 3681 N at 0.5 MPa.
For practical sizing, plan for a safe working load of roughly 2356 N, which accounts for seal friction at 0.5 MPa. In vertical lifting scenarios, this translates to hoisting about 200 kg safely with a 2:1 margin. This unit lacks the -S magnet, meaning it cannot support CMSG, DMSG, or EMSG magnetic switches. If your environment exceeds 70 C, you can specify the Viton H high-temperature seal option to safely operate up to 150 C.

Where the Airtac SAU Standard Air Cylinder SAU100X145 Is Used
Heavy Stamping Presses
Drives robust stamping dies requiring substantial push force, utilizing the 3927 N capability at 0.5 MPa to form thick metal components reliably.
Pallet Transfer Stops
Halts heavy loaded pallets on assembly lines, where the compact profile length prevents interference with passing robotic loaders.
Industrial Lift Gates
Actuates large warehouse distribution gates, safely moving masses approaching the 200 kg vertical lift threshold with a 2:1 safety factor.
Is the Airtac SAU Standard Air Cylinder SAU100X145 the Right Cylinder?
When sizing this actuator, consider the neighboring bores: stepping down to the 63 mm bore yields 1559 N of push force at 0.5 MPa, while the 80 mm bore provides 2513 N. Stepping up is not possible as 100 mm is the largest available SAU bore. Because this specific SKU lacks the -S magnet, it cannot accept magnetic position sensors. You can mount it using AirTAC SC-series accessories like LB foot brackets, FA/FB flanges, or CA/CB clevises. Note that an air cushion only decelerates the piston near the stroke end; it does not act as a brake. To prevent drift from gravity or air loss, 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 SAU100X145 FAQ
This 100 mm bore model features a 1/2" port and an M20x1.5 rod thread. It delivers a push force of 3927 N and a pull force of 3681 N at 0.5 MPa, a push force of 5497 N at 0.7 MPa, and a theoretical maximum of 801 kgf at 1.0 MPa.
You can use standard AirTAC SC-series mounting hardware like FA flanges or LB foot brackets. However, because this SAU100X145 SKU does not include the -S magnet, it cannot accept CMSG, DMSG, or EMSG magnetic switches for position sensing.
