About the Airtac SAI100 Standard Air Cylinder SAI100AX25
The AirTAC SAI100X25 is a double-acting ISO 15552 profile cylinder featuring a 100mm bore and a 25mm stroke. It delivers a robust push force of 3927 N at 0.5 MPa, making it well-suited for high-thrust, short-travel operations. The extruded aluminum barrel design omits tie rods, providing a clean exterior that is fully dimensionally interchangeable per ISO 15552.
This specific configuration uses a SUS420J2 stainless steel piston rod (material code A), offering excellent corrosion resistance for harsher industrial environments. It utilizes PT tapered port threads and does not include a magnet, meaning it is optimized for pure pneumatic actuation without requiring external position sensing.

Where the Airtac SAI100 Standard Air Cylinder SAI100AX25 Is Used
High-Force Pressing
Ideal for short-stroke stamping, clamping, and pressing operations requiring substantial thrust within a compact movement range.
Heavy Material Handling
Provides the robust actuation needed to push, lift, or divert heavy products or pallets on automated manufacturing lines.
Rugged Machinery Integration
Excels in demanding industrial environments where the SUS420J2 stainless steel rod offers superior resistance to moisture and wear.
Is the Airtac SAI100 Standard Air Cylinder SAI100AX25 the Right Cylinder?
When selecting this model, consider that stepping down to an 80mm bore reduces the 0.5 MPa push force to 2513 N, while this 100mm bore provides 3927 N for heavier pressing and lifting tasks. Because the standard SAI is a double-acting cylinder, it will drift if air pressure is lost; if your application requires true load holding without live pressure, use the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variants. To match this ISO 15552 replacement, ensure the 100mm bore, 25mm stroke, PT G1/2 port, and appropriate mounting accessory (such as an FA flange or LB foot) are specified.
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.
