Airtac SAU Standard Air Cylinder SAU100X900S
The AirTAC Airtac SAU Standard Air Cylinder SAU100X900S is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 900mm 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 SAU100X900S
The AirTAC SAU100X900S is a double-acting profile-type standard cylinder featuring a 100 mm bore and a 900 mm stroke. Because it uses an extruded aluminum profile barrel rather than a conventional design, it is noticeably shorter 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 suitable for heavy-duty positioning tasks.
This unit includes a built-in piston magnet (-S) for direct mounting of CMSG, DMSG, or EMSG sensors along the barrel groove. For practical sizing, plan for a safe working load of roughly 2356 N, which accounts for seal friction during smooth travel. If lifting vertically, this actuator can safely handle about 200 kg when applying a 2:1 safety margin. The fluid port is 1/2", and the piston rod end features an M20x1.5 thread.

Where the Airtac SAU Standard Air Cylinder SAU100X900S Is Used
Heavy Press Ejection
Provides the 3927 N push force required to eject dense stamped metal components from a hydraulic press bed over a long 900 mm travel distance.
Pallet Dispenser Pusher
Separates empty pallets in automated handling lines, utilizing the 200 kg vertical lift equivalent to reliably index heavy wood or plastic pallet stacks.
Logistics Divert Arm
Actuates a long sweeping arm to route heavy parcel shipments between merging conveyor belts, relying on the compact profile to fit tight transfer zones.
Is the Airtac SAU Standard Air Cylinder SAU100X900S the Right Cylinder?
When sizing this actuator, consider the neighboring bores to ensure optimal performance. Stepping down to the 80 mm bore reduces the 0.5 MPa push force to 2513 N, while the 100 mm bore provides 3927 N, making this model the top tier for standard high-force requirements. For applications requiring a held load during air loss or valve centering, note that the standard piston will drift; an external rod lock or pilot-operated check valve is required, as the adjustable 29 mm air cushions only decelerate the piston near stroke ends.
With a 900 mm stroke, the Ø25 mm rod is susceptible to bending under lateral stress, so external guide rails must support the load to prevent side-loading damage. Mounting is straightforward using AirTAC SC-series accessories, including LB foot brackets, FA/FB flanges, and CA/CB clevises. The included -S magnet enables precise end-of-stroke detection with CMSG, DMSG, or EMSG switches.

- ✓ 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 SAU100X900S FAQ
At 0.5 MPa, the push force is 3927 N and the pull force is 3681 N. At 0.7 MPa, the push force is 5497 N, and at 0.9 MPa it is 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. Speed ranges from 30-800 mm/s.
Yes, the -S designation means this model has a built-in piston magnet, allowing the use of CMSG, DMSG, or EMSG switches in the barrel groove. For mounting, it shares identical accessories with the AirTAC SC series, including LB foot, FA/FB flange, and CA/CB clevis brackets, but it is not dimensionally interchangeable with ISO 15552 cylinders.
