Airtac SAU Standard Air Cylinder SAU100X270S
The AirTAC Airtac SAU Standard Air Cylinder SAU100X270S is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 270mm 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 SAU100X270S
The AirTAC SAU100X270S is a double-acting profile-type cylinder engineered to be physically shorter than a same-bore ISO 15552 unit, granting a major spatial advantage in tight machine layouts. It features a 100 mm bore, a 270 mm stroke, and a robust Ø25 mm hard-chrome plated carbon steel rod with an M20x1.5 thread. Operating at 0.15-1.0 MPa, it moves at 30-800 mm/s through a 1/2" air port, generating 3927 N of push force and 3681 N of pull force at 0.5 MPa.
For practical sizing, plan for a safe working load of roughly 2356 N, which accounts for seal friction at 0.5 MPa rather than relying on the absolute maximum. This translates to lifting about 200 kg vertically with a 2:1 safety margin. The extruded aluminum barrel incorporates a built-in sensor groove, and because this SKU includes the -S magnet, it directly supports CMSG, DMSG, or EMSG reed and electronic switches. If your environment exceeds the standard -20 to +70 C range, you can specify the Viton H high-temperature seal option to handle up to 150 C.

Where the Airtac SAU Standard Air Cylinder SAU100X270S Is Used
Heavy-Duty Stamping Press
Drives a 150 kg upper die set in an automotive parts stamping line, utilizing the 3927 N push force at 0.5 MPa to form steel brackets reliably.
Pallet Dispenser Mechanism
Lifts and feeds empty wooden pallets into an automated packaging conveyor, where the compact profile length prevents interference with the guard framing.
Injection Mold Ejection
Pushes heavy molded plastic components out of a large tool, using the integrated -S magnet and DMSG sensor to confirm full ejection before the robot arm extracts the part.
Is the Airtac SAU Standard Air Cylinder SAU100X270S the Right Cylinder?
When sizing this unit, compare it against its neighbors: stepping down to an 80 mm bore lowers the 0.5 MPa push force to 2513 N, while moving up is not an option as 100 mm is the largest available SAU bore. Because this 270 mm stroke is approaching the longer end of the spectrum, ensure your mounting arrangement prevents rod bending by guiding the load externally to avoid excessive side-load stress. The adjustable 29 mm air cushions at both ends help decelerate the piston smoothly, but remember they are not a locking mechanism; if air pressure drops or the valve centers, the load will drift, requiring an external rod lock or pilot-operated check valve for secure holding. Mounting is straightforward using AirTAC SC-series accessories, including LB foot brackets, FA/FB flanges, and CA/CB clevises.
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 SAU100X270S FAQ
This 100 mm bore model uses a 1/2" air port and an M20x1.5 rod thread. The force output is 3927 N push and 3681 N pull at 0.5 MPa, 5497 N push at 0.7 MPa, 7068 N push at 0.9 MPa, with a theoretical maximum of 801 kgf at 1.0 MPa.
No, it is not dimensionally interchangeable with ISO 15552 standards. The SAU is a compact profile cylinder, so you must use AirTAC SC-series mounting accessories like LB foot brackets, FA/FB flanges, or CA/CB clevises for proper installation.
