Airtac SAU Standard Air Cylinder SAU100X220S
The AirTAC Airtac SAU Standard Air Cylinder SAU100X220S is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 220mm 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 SAU100X220S
The AirTAC SAU100X220S is a double-acting profile-type cylinder engineered for heavy-duty automation. It delivers a robust 3927 N push force at 0.5 MPa, making it ideal for high-thrust tasks. Because it uses an extruded aluminum barrel rather than a standard tie-rod assembly, its overall length is shorter than an ISO 15552 cylinder of the same bore, saving valuable machine space. This specific unit includes a built-in piston magnet, allowing you to mount CMSG, DMSG, or EMSG sensors directly into the barrel groove for precise position detection.
For practical sizing, plan for a safe working load of about 2356 N, which accounts for seal friction at 0.5 MPa. If lifting vertically, this actuator can safely handle approximately 200 kg when applying a 2:1 safety margin. The unit features a 1/2 inch air port and a 25 mm rod. If your application sees ambient temperatures above 70 C, you can specify the Viton H high-temperature seal option to extend the operating range up to 150 C.

Where the Airtac SAU Standard Air Cylinder SAU100X220S Is Used
Heavy Stamping Press
Drives the heavy-duty stamping die with a 3927 N push force at 0.5 MPa, ensuring consistent metal forming in automotive part production.
Pallet Handling Gate
Actuates a robust 200 kg vertical lift gate in a high-throughput logistics conveyor system, utilizing the 220 mm stroke to clear the pathway.
Injection Mold Clamp
Secures large injection molding tools within a compact machine frame, taking advantage of the shorter profile design to minimize overall footprint.
Is the Airtac SAU Standard Air Cylinder SAU100X220S the Right Cylinder?
When sizing this 100 mm bore actuator, compare its 3927 N push force at 0.5 MPa against the neighboring bores. The 80 mm bore provides 2513 N, which may be insufficient for heavy loads, while the 100 mm bore itself offers a massive 801 kgf theoretical maximum at 1.0 MPa. Since this model has the -S suffix, it is fully compatible with CMSG, DMSG, and EMSG switches. You can mount it using AirTAC SC-series accessories, including LB foot brackets, FA flanges, or CA clevises.
Remember that a standard double-acting cylinder will drift if air pressure is lost or the valve is centered. The adjustable air cushions only decelerate the piston near the end of the stroke to prevent impact damage; they do not function as a braking mechanism. To safely suspend a load, integrate 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 SAU100X220S FAQ
This 100 mm bore cylinder features a 1/2 inch air port and a 25 mm piston rod. 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 the theoretical maximum force is 801 kgf at 1.0 MPa.
You cannot use ISO 15552 brackets, as the SAU is a distinct profile-type cylinder. However, it shares mounting accessories with the AirTAC SC series, such as LB, FA, and CA brackets. Because this model includes the -S magnet, you can install CMSG, DMSG, or EMSG sensors directly into the barrel groove.
