Airtac SAU Standard Air Cylinder SAU100X20
The AirTAC Airtac SAU Standard Air Cylinder SAU100X20 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 SAU100X20
The AirTAC SAU100X20 is a double-acting profile-type cylinder engineered for heavy-duty tasks within a compact footprint. It is purposefully shorter than an ISO 15552 cylinder of the same 100 mm 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 length tailored for extremely short travel requirements. The unit features a 1/2" air port and a 25 mm carbon steel rod with an M20x1.5 thread.
For practical application, plan for a safe working load of roughly 2356 N at 0.5 MPa to account for seal friction and smooth travel. This translates to a vertical lift capacity of about 200 kg when applying a 2:1 safety margin. The extruded aluminum barrel includes a sensor groove, but because this SKU lacks the -S magnet option, it cannot support CMSG, DMSG, or EMSG magnetic switches. You can specify Viton H seals if your environment requires high-temperature resistance up to 150 C.

Where the Airtac SAU Standard Air Cylinder SAU100X20 Is Used
Short-Stroke Stamping
Applies 3927 N of force at 0.5 MPa for brief metal forming or embossing tasks where a 20 mm travel is sufficient.
Heavy Clamping Jigs
Secures thick steel plates in fabrication fixtures, utilizing the 100 mm bore power without consuming excessive machine length.
Riveting Press
Drives fasteners into heavy assemblies, taking advantage of the compact profile to fit within dense automated cell layouts.
Is the Airtac SAU Standard Air Cylinder SAU100X20 the Right Cylinder?
Choosing this 100 mm bore involves sizing against its neighbors: dropping to a 63 mm bore reduces the 0.5 MPa push force to 1559 N, while an 80 mm bore provides 2513 N. Stepping up is unnecessary as the 100 mm bore already tops the SAU range with 3927 N. Because this is a plain cylinder without a magnet, position sensing is not supported. For mounting, utilize AirTAC SC-series accessories like LB foot brackets, FA/FB flanges, or CA/CB clevises. Note that the adjustable air cushion at both ends only decelerates the piston near the stroke end; it does not lock the rod. If your machine requires the load to be held during air loss or valve centering, you must 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 SAU100X20 FAQ
This 100 mm bore model uses a 1/2" air port. At 0.5 MPa it provides 3927 N of push force and 3681 N of pull force. At 0.7 MPa the push force is 5497 N, and at 0.9 MPa it is 7068 N. The theoretical maximum force is 801 kgf at 1.0 MPa.
It is not an ISO 15552 cylinder and does not share that footprint, but it is fully compatible with AirTAC SC-series mounting accessories like LB, FA, and CA brackets. Additionally, because this specific SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG magnetic sensors.
