About the Airtac SAI100 Standard Air Cylinder SAI100BX25S
The AirTAC SAI100X25-S is a double-acting ISO 15552 profile cylinder engineered for high-force, short-stroke operations. It delivers a robust push force of 3927 N and a pull force of 3681 N at 0.5 MPa, making it ideal for heavy pressing and clamping tasks within a compact 25 mm stroke.
This specific configuration includes a SUS304 stainless steel rod for superior corrosion resistance and a built-in magnet for seamless integration with CMSE or DMSE sensor switches. The extruded aluminum barrel features sensor grooves on both sides, simplifying switch mounting.

Where the Airtac SAI100 Standard Air Cylinder SAI100BX25S Is Used
Heavy-Duty Stamping
Provides the high instantaneous force needed for short-stroke stamping and forming operations in metal fabrication.
Industrial Clamping
Secures heavy workpieces during machining or welding, utilizing the 3927 N push force to hold components rigidly in place.
Product Ejection
Ejects dense or heavy finished parts from machinery molds and press beds quickly over a compact 25 mm travel distance.
Is the Airtac SAI100 Standard Air Cylinder SAI100BX25S the Right Cylinder?
Select this 100 mm bore model when an 80 mm bore (providing 2513 N push at 0.5 MPa) lacks the necessary thrust for your application. The 25 mm stroke is optimized for brief, powerful movements. Because this is a standard double-acting cylinder, it will not maintain its position if air pressure is lost; for applications requiring dead-end holding without live pressure, consider the SAIL or BSAI locking variants.
To ensure a true drop-in replacement, match your existing ISO 15552 dimensions, 25 mm stroke, G1/2 PT port, and mounting accessories like the TC trunnion or FA flange. The integrated magnet (-S) allows for precise end-of-stroke detection.
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 SAI100BX25S FAQ
At an operating pressure of 0.5 MPa, this 100 mm bore cylinder generates a push force of 3927 N and a pull force of 3681 N. At 0.7 MPa, the push force increases to 5497 N.
Yes, the SAI100X25-S is dimensionally interchangeable per ISO 15552 standards. You can drop it into existing setups matching the 100 mm bore, 25 mm stroke, and G1/2 port size without modifying the mounting interface.
