About the Airtac SAI100 Standard Air Cylinder SAI100BX25
The AirTAC SAI100X25 is a double-acting ISO 15552 profile cylinder engineered for short-stroke heavy pushing. It provides 3927N of thrust at 0.5 MPa and uses a G1/2 port to drive the 25mm stroke effectively.
This configuration features a SUS304 stainless steel rod for superior corrosion resistance and includes a PT tapered port thread. The extruded aluminum barrel incorporates sensor grooves on both sides for direct DMSE switch mounting.

Where the Airtac SAI100 Standard Air Cylinder SAI100BX25 Is Used
Heavy Duty Clamping
Generates 3927N at 0.5 MPa to secure heavy metal workpieces during machining operations.
Pallet Stopping
Short 25mm stroke provides a robust barrier to halt large pallets on high-mass conveyor lines.
Press Ejection
Delivers high-force short-burst push to eject dense parts from press beds quickly.
Is the Airtac SAI100 Standard Air Cylinder SAI100BX25 the Right Cylinder?
Choose this 100mm bore when a 80mm bore (2513N at 0.5 MPa) lacks the necessary push strength for a short clamping task. Because the stroke is only 25mm, rod-bearing bending from side loads is minimal, though external guides remain best practice for offset loads. For ISO 15552 dimensional interchangeability, match the 100mm bore, 25mm stroke, G1/2 port, and your required mounting accessory. Note that this standard cylinder relies on adjustable air cushions to decelerate the piston at stroke ends; it will not hold a load if air pressure drops. If your application requires fail-safe position holding, consider the BSAI clamp-lock variant.
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 SAI100BX25 FAQ
At 0.5 MPa, the push force is 3927N and the pull force is 3681N. At 0.7 MPa, the push force increases to 5497N.
Yes, the SAI100X25 is dimensionally interchangeable per ISO 15552. Match the 100mm bore, 25mm stroke, G1/2 port, and mounting interface to replace equivalent profile cylinders.
