About the Airtac SAI100 Standard Air Cylinder SAI100AX125S
The AirTAC SAI100X125-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a robust 3927 N push force at 0.5 MPa, this 100 mm bore unit is built to drive substantial masses. The 125 mm stroke provides the precise extension needed for high-impact operations.
This variant features a SUS420J2 stainless steel rod for superior corrosion resistance in humid or washdown environments. Equipped with a magnet (-S), it integrates seamlessly with CMSE and DMSE sensor switches fitted into the dual-side barrel grooves. Threaded PT ports ensure a reliable, tapered pneumatic connection.

Where the Airtac SAI100 Standard Air Cylinder SAI100AX125S Is Used
Heavy Stamping Press
Provides the 3927 N push force required to actuate heavy stamping and forming dies in metal fabrication lines.
Pallet Diverting
Extends 125 mm to push large loaded pallets off high-throughput conveyor belts with sustained authority.
Plastic Mold Ejection
Drives robust ejection pins in injection molding cells, utilizing the SUS420J2 rod to resist humid plant environments.
Is the Airtac SAI100 Standard Air Cylinder SAI100AX125S the Right Cylinder?
Selecting this 100 mm bore makes sense when 80 mm (2513 N at 0.5 MPa) is insufficient but the massive 125 mm (6136 N) frame would overconstrain your spatial envelope. The 125 mm stroke avoids the rod-bearing bending risks seen in longer extensions, keeping side-load friction minimal.
Remember that pneumatic cushions only decelerate the piston near the end caps; they do not lock the load. If your machinery loses air pressure, the rod will drift. For suspended loads requiring fail-safe holding, consider the SAIL locking variant or an external pilot-operated check valve. This genuine AirTAC component is dimensionally interchangeable per ISO 15552, featuring a 100 mm bore, 125 mm stroke, PT G1/2 ports, and standard mounting accessories like FA flanges.

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.
