Airtac SAU Standard Air Cylinder SAU100X550S
The AirTAC Airtac SAU Standard Air Cylinder SAU100X550S is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 550mm 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 SAU100X550S
The AirTAC SAU100X550S is a double-acting profile-type cylinder featuring a 100 mm bore and 550 mm stroke. Because it uses an extruded aluminum barrel rather than a conventional design, it is shorter and more compact than an ISO 15552 cylinder of the same bore, saving valuable machine space. It delivers a robust 3927 N push force at 0.5 MPa, making it ideal for heavy-duty positioning tasks.
For practical sizing, plan for a safe working load of about 2356 N, which accounts for seal friction at 0.5 MPa. Vertically, this translates to lifting roughly 200 kg with a 2:1 safety margin. The 1/2" port and M20x1.5 rod thread handle high airflow, while the included -S magnet allows direct mounting of CMSG, DMSG, or EMSG sensors in the profile groove.

Where the Airtac SAU Standard Air Cylinder SAU100X550S Is Used
Heavy Stamping Press
Drives a 180 kg upper die set in an automotive stamping line, utilizing the 3927 N push force to form steel panels reliably.
Pallet Dispenser
Pushes empty pallets into a high-speed packaging conveyor, where the compact profile length prevents interference with adjacent safety guarding.
Injection Mold Ejector
Actuates a heavy mold ejection plate over the 550 mm travel, relying on the integrated magnet for precise end-of-stroke confirmation.
Is the Airtac SAU Standard Air Cylinder SAU100X550S the Right Cylinder?
When sizing this actuator, compare its 3927 N push force at 0.5 MPa against the neighboring bores: an 80 mm bore provides 2513 N, while the 100 mm offers this model's higher capacity. Because this unit features a 550 mm stroke, you must use external guide rails to prevent rod bending and absorb side loads. Mounting relies on AirTAC SC-series accessories like LB foot brackets, FA flanges, or CA clevises. Remember that air cushions only decelerate the piston near the stroke ends; they do not act as a brake. If the load must remain stationary during air loss or valve centering, install an external rod lock or 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 SAU100X550S FAQ
This 100 mm bore cylinder features a 1/2" 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.
No, it is not an ISO 15552 cylinder, but it is notably shorter and more compact than one. Mounting accessories are shared with the AirTAC SC series, utilizing LB foot, FA flange, or CA clevis brackets. The -S suffix indicates a built-in magnet for CMSG, DMSG, or EMSG sensors.
