Airtac SAU Standard Air Cylinder SAU100X50FA
The AirTAC Airtac SAU Standard Air Cylinder SAU100X50FA is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 50mm 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 SAU100X50FA
The AirTAC SAU100X50FA is a double-acting profile-type cylinder engineered for heavy-duty tasks, delivering a push force of 3927 N and a pull force of 3681 N at 0.5 MPa. Its extruded aluminum barrel with a 1/2 inch port and M20x1.5 rod thread provides a rigid, compact footprint that is notably shorter than an ISO 15552 cylinder of the same bore. This space efficiency is a major advantage when integrating high-thrust actuators into densely packed machinery.
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 applications, this translates to hoisting about 200 kg safely with a 2:1 margin. The unit includes an FA flange mount from the AirTAC SC-series accessories. Note that this specific SKU lacks a magnet, so it cannot support CMSG, DMSG, or EMSG magnetic sensors.

Where the Airtac SAU Standard Air Cylinder SAU100X50FA Is Used
Press Fit Assembly
Drives heavy bushings and bearings into automotive transmission housings, utilizing the 3927 N push force at 0.5 MPa to seat components reliably without requiring a full hydraulic system.
Injection Mold Clamping
Secures medium-tonnage plastic injection molds using the front FA flange mount, providing the rigid holding power needed during low-pressure mold closing sequences.
Pallet Destacking
Separates loaded pallets at the bottom of high-speed packaging lines, where the 200 kg safe vertical lift capacity easily manages heavy wooden pallet bases.
Is the Airtac SAU Standard Air Cylinder SAU100X50FA the Right Cylinder?
When sizing this 100 mm bore actuator, compare it against neighboring bores: a 63 mm option yields 1559 N push at 0.5 MPa, while this 100 mm unit provides 3927 N. If you need even more power, you are at the top of the SAU range with a theoretical maximum of 801 kgf at 1.0 MPa. The integrated FA flange ensures secure front mounting, and you can utilize SC-series knuckles like I, Y, F, or U for varied load connections.
Remember that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered; the adjustable 29 mm air cushions at both ends only decelerate the piston near stroke end and do not function as a braking lock. For suspended or vertical loads that must maintain position during a pressure drop, incorporate an external rod lock or a pilot-operated check valve into your pneumatic circuit.
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 SAU100X50FA FAQ
At 0.5 MPa, the push force is 3927 N and the pull force is 3681 N. At 0.7 MPa it pushes 5497 N, and at 0.9 MPa it pushes 7068 N. The theoretical maximum force is 801 kgf at 1.0 MPa. Operating pressure ranges from 0.15-1.0 MPa, with a proof pressure of 1.5 MPa and a speed range of 30-800 mm/s.
No, this specific SKU does not include a magnet. To use CMSG, DMSG, or EMSG switches in the profile groove, you must order an SAU model with the -S suffix. Additionally, while it shares SC-series mounting accessories like the FA flange, it is a compact profile cylinder and is not dimensionally interchangeable with ISO 15552 standards.
