Airtac SAU Standard Air Cylinder SAU100X45S
The AirTAC Airtac SAU Standard Air Cylinder SAU100X45S is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 45mm 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 SAU100X45S
The AirTAC SAU100X45S is a double-acting profile-type cylinder built for heavy-duty tasks within a tight machinery footprint. It is engineered to be noticeably shorter than an ISO 15552 cylinder of the same 100 mm bore, yielding a significant space advantage without sacrificing power. It delivers a robust 3927 N of push force and 3681 N of pull force at 0.5 MPa, operating via a 1/2 inch air port and a 25 mm carbon steel rod with an M20x1.5 thread.
For practical sizing, plan for a safe working load of roughly 2356 N, which accounts for seal friction and smooth travel at 0.5 MPa. In vertical lifting scenarios, this translates to hoisting about 200 kg safely with a 2:1 margin. The integrated -S piston magnet allows direct mounting of CMSG, DMSG, or EMSG switches into the barrel groove for precise position detection. If your environment exceeds standard -20 to +70 C temperatures, you can specify the Viton H high-temperature seal option to handle up to 150 C.

Where the Airtac SAU Standard Air Cylinder SAU100X45S Is Used
Press Fit Assembly
Drives heavy bearings into automotive transmission housings, utilizing the 3927 N push force to seat components rigidly without requiring a massive machine envelope.
Pallet Stopping Gate
Acts as a robust pneumatic stop gate for loaded pallets up to 200 kg on a conveyor, safely halting movement while the compact profile preserves floor space.
Injection Mold Ejection
Ejects dense plastic or composite parts from molding machinery, using the 45 mm stroke to clear the die face quickly at cycle speeds up to 800 mm/s.
Is the Airtac SAU Standard Air Cylinder SAU100X45S the Right Cylinder?
When sizing this actuator, compare it against adjacent bores: the 80 mm variant provides 2513 N push at 0.5 MPa, while the 100 mm unit offers 3927 N. If you require even more thrust, note that 100 mm is the largest standard SAU bore available. Because this is a non-standard 45 mm stroke, ensure your machinery accommodates the exact extension dimensions. The 1/2 inch port and 29 mm adjustable air cushions at both ends manage the kinetic energy of this high-force class effectively.
Keep in mind that a standard double-acting cylinder will drift if air pressure drops or the valve is centered, as the cushions only decelerate the piston near stroke ends rather than locking it. For suspended loads, integrate an external rod lock or a pilot-operated check valve. Mounting is straightforward using AirTAC SC-series accessories, including LB foot brackets, FA/FB flanges, and CA/CB clevises. The included -S magnet enables reliable electronic or reed sensor feedback.

- ✓ 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 SAU100X45S 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. The theoretical maximum force is 801 kgf at 1.0 MPa.
The SAU profile barrel is shorter than an ISO 15552 cylinder of the same bore and uses AirTAC SC-series mounting accessories like LB, FA, and CA brackets. The -S suffix indicates a built-in piston magnet, allowing CMSG, DMSG, or EMSG switches to be fitted directly into the barrel groove.
