Airtac SAU Standard Air Cylinder SAU100X55
The AirTAC Airtac SAU Standard Air Cylinder SAU100X55 is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 55mm 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 SAU100X55
The AirTAC SAU100X55 is a double-acting profile-type cylinder engineered for heavy-duty tasks. It features a 100 mm bore and a 55 mm stroke, delivering a push force of 3927 N at 0.5 MPa. Its extruded aluminum barrel makes it more compact than an ISO 15552 cylinder of the same bore, saving valuable machine space. The unit uses a 1/2 inch air port and a 25 mm carbon steel rod with an M20x1.5 thread.
For practical sizing, plan for a safe working load of roughly 2356 N at 0.5 MPa, accounting for seal friction and smooth travel. This translates to lifting about 200 kg vertically with a 2:1 safety margin. The standard TPU seals handle temperatures from -20 to +70 C, while a Viton H option extends this to 150 C. Note that this specific SKU lacks the -S magnet, meaning it cannot support CMSG, DMSG, or EMSG sensor switches.

Where the Airtac SAU Standard Air Cylinder SAU100X55 Is Used
Press Fit Assembly
Drives heavy bearings into automotive housings, utilizing the 3927 N push force at 0.5 MPa to seat components reliably.
Pallet Stopper Gate
Acts as a robust blocking mechanism in high-capacity conveyor lines, halting loaded pallets weighing up to 200 kg safely.
Injection Mold Clamp
Secures heavy tooling plates in plastic molding setups, taking advantage of the compact profile to fit tight machine frames.
Is the Airtac SAU Standard Air Cylinder SAU100X55 the Right Cylinder?
When sizing this 100 mm bore model, consider the neighboring options. If your application requires less force, the 80 mm bore provides 2513 N push at 0.5 MPa. If you need more power, this 100 mm bore reaches 7068 N at 0.9 MPa. Keep in mind that a plain cylinder drifts when air is lost or the valve is centered; the adjustable 29 mm air cushions only decelerate the piston near stroke ends. For secure load holding, integrate an external rod lock or a pilot-operated check valve. Mounting is straightforward using AirTAC SC-series accessories like LB foot, FA flange, or CA clevis brackets.
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 SAU100X55 FAQ
The SAU100X55 features a 1/2 inch 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, and the theoretical maximum force is 801 kgf at 1.0 MPa.
No, it is not an ISO 15552 cylinder, but it is shorter and more compact. Mounting compatibility is strictly with the AirTAC SC-series accessories, including LB foot, FA/FB flange, and CA/CB clevis brackets. Also, this SKU lacks a magnet, so it cannot accept sensors.
