About the Airtac SAI100 Standard Air Cylinder SAI100AX25S
The AirTAC SAI100X25-S is a double-acting ISO 15552 profile cylinder engineered for high-force, short-stroke tasks. It provides a robust push force of 3927 N and a pull force of 3681 N at 0.5 MPa. The 25 mm stroke is optimal for compact clamping, pressing, or ejection operations where space is restricted but substantial thrust is required.
This configuration includes a magnetic piston (-S) for direct integration with CMSE or DMSE reed switches, utilizing the dual sensor grooves on the extruded aluminum barrel. The piston rod is constructed from SUS420J2 stainless steel (rod code A) for enhanced corrosion resistance, and it features PT tapered port threads. As a genuine ISO 15552 standard cylinder, it offers a true drop-in dimensional replacement for comparable profiles.

Where the Airtac SAI100 Standard Air Cylinder SAI100AX25S Is Used
Heavy-Duty Clamping
Secures thick metal plates or heavy castings during machining operations, utilizing its 3927 N push force to prevent workpiece shifting under high cutting loads.
Industrial Stamping
Performs short-stroke marking, riveting, or light stamping tasks where a compact 25 mm stroke delivers rapid, high-impact force in automated assembly cells.
Pallet Ejection
Pushes heavy loaded pallets off a conveyor line, using the robust 100 mm bore to generate immediate thrust within a confined ejection zone.
Is the Airtac SAI100 Standard Air Cylinder SAI100AX25S the Right Cylinder?
Select this 100 mm bore when an application demands nearly 4000 N of force at 0.5 MPa but has a strict axial length limit. If your setup requires less force, stepping down to an 80 mm bore yields 2513 N at 0.5 MPa and saves valuable space. Conversely, if you need over 6000 N, the 125 mm bore is the next logical step.
Because this is a short-stroke actuator, side-load stress on the rod bearing is minimal compared to longer units. However, remember that the standard adjustable air cushions only decelerate the piston at end-of-stroke; they do not lock the rod. If your process must hold a load securely during a pressure loss, specify the SAIL variant with an air-released lock or use an external pilot-operated check valve.
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.
Airtac SAI100 Standard Air Cylinder SAI100AX25S FAQ
At 0.5 MPa operating pressure, this 100 mm bore cylinder generates a push force of 3927 N and a pull force of 3681 N. If pressure is increased to 0.7 MPa, the push force rises to 5497 N.
Yes, the SAI100X25-S is built to ISO 15552 dimensional standards, making it a drop-in replacement for other profile cylinders of the same bore and stroke. It uses a G1/2 port and accepts standard FA, LB, and TC mounting accessories.
