About the Airtac SAI100 Standard Air Cylinder SAI100AX900S
The AirTAC SAI100X900-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a robust 5497 N of push force at 0.7 MPa, it features a 900 mm stroke and a PT tapered port thread for secure pneumatic connections. This genuine AirTAC actuator integrates a magnet for use with CMSE and DMSE sensor switches.
Built with a SUS420J2 stainless steel piston rod (material code A), this model provides excellent corrosion resistance and durability in demanding environments. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting, while adjustable air cushions at both ends absorb kinetic energy near the stroke limits.

Where the Airtac SAI100 Standard Air Cylinder SAI100AX900S Is Used
Material Transfer Line
Provides the long 900 mm reach and 5497 N push force needed to index heavy pallets between robotic machining stations.
Automated Storage Retrieval
Extends deep into storage lanes to push or extract heavy inventory containers with precise 100 mm bore power.
Large Panel Handling
Cycles large sheet materials or structural panels into processing machinery, utilizing the full 900 mm stroke length.
Is the Airtac SAI100 Standard Air Cylinder SAI100AX900S the Right Cylinder?
This 100 mm bore generates 5497 N at 0.7 MPa, offering a significant step up from the 63 mm bore (2182 N) for high-mass handling, while avoiding the larger footprint of the 160 mm bore (14074 N). Because this model features a 900 mm stroke, the extended rod is highly susceptible to bending under side loads. An external guide rail or a guided cylinder carriage is strongly recommended to prevent rod-bearing damage.
If your application requires the load to remain held when air pressure is exhausted or dropped, a standard SAI cannot maintain position. For fail-safe holding, consider the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variants. This SAI100X900-S is dimensionally interchangeable per ISO 15552, accepting standard PT porting, a 900 mm stroke, and standard mounting accessories.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/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/TC).
- check Installation by qualified personnel per AirTAC docs.
