Airtac SAU Standard Air Cylinder SAU100X20S
The AirTAC Airtac SAU Standard Air Cylinder SAU100X20S is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 20mm 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 SAU100X20S
The AirTAC SAU100X20S is a double-acting profile-type cylinder engineered for high-force tasks in a compact footprint. It is purposefully shorter than an ISO 15552 cylinder of the same bore, delivering a robust 3927 N of push force at 0.5 MPa. This specific 20 mm stroke is a non-standard, made-to-order dimension tailored for very short travel requirements. It features a 1/2 inch air port and a 25 mm piston rod.
Because seal friction and smooth travel reduce usable energy, you should plan for a safe working load of roughly 2356 N at 0.5 MPa. For vertical lifting, this translates to hoisting about 200 kg with a 2:1 safety margin. The -S suffix indicates a built-in piston magnet, enabling CMSG, DMSG, or EMSG electronic switches to sit directly in the profile groove for precise end-position detection.

Where the Airtac SAU Standard Air Cylinder SAU100X20S Is Used
Heavy Stamping Press
Provides intense 3927 N clamping force for securing thick sheet metal blanks inside a short-stroke stamping die.
High-Pressure Gate Valve
Actuates large industrial fluid gates where a brief 20 mm movement is required to seal against heavy flow pressure.
Automated Riveting Head
Drives a heavy-duty riveting tool head downward to upset fasteners with precise, high-impact short-stroke positioning.
Is the Airtac SAU Standard Air Cylinder SAU100X20S the Right Cylinder?
When sizing this actuator, compare it against its neighbors: the 80 mm bore yields 2513 N push at 0.5 MPa, while no larger standard SAU bore exists, making this 100 mm unit the maximum force option at 3927 N. If your application demands holding a load vertically during air loss or valve centering, note that the standard piston will drift; the adjustable air cushion only decelerates the stroke near the end and acts purely as an end-of-travel buffer, never as a locking brake. You must integrate an external rod lock or a pilot-operated check valve for secure load holding.
Mounting hardware is fully compatible with AirTAC SC-series accessories, including LB foot mounts, FA/FB flanges, and CA/CB clevises. Because the 20 mm stroke is exceptionally short, side-load risks are minimal, but always ensure the rod-end thread (M20x1.5) is rigidly coupled to your load to prevent binding.
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 SAU100X20S FAQ
This 100 mm bore cylinder features a 1/2 inch air port. It delivers 3927 N push and 3681 N pull at 0.5 MPa, 5497 N push at 0.7 MPa, and a theoretical maximum of 801 kgf at 1.0 MPa.
No, the SAU is a compact profile cylinder, not an ISO 15552 unit. It is shorter than ISO cylinders and uses AirTAC SC-series mounting accessories like LB foot, FA/FB flange, and CA/CB clevis brackets.
