About the Airtac SAI100 Standard Air Cylinder SAI100BX15
The AirTAC SAI100X15 is a double-acting ISO 15552 profile cylinder engineered for high-force, short-stroke operations. It provides a robust push force of 3927 N and a pull force of 3681 N at 0.5 MPa, making it highly effective for compact pressing and heavy clamping tasks.
This specific configuration utilizes a SUS304 stainless steel piston rod (material code B) for superior corrosion resistance, alongside PT tapered port threads. The extruded aluminum barrel features sensor grooves on both sides, allowing for straightforward position monitoring when paired with compatible switches.

Where the Airtac SAI100 Standard Air Cylinder SAI100BX15 Is Used
Short-Stroke Pressing
Ideal for high-force pressing and stamping operations where a 15 mm stroke provides rapid, concentrated impact without requiring a long cylinder footprint.
Heavy Duty Clamping
Delivers 3927 N of push force at 0.5 MPa to securely hold heavy workpieces in place during machining, welding, or assembly processes.
Ejector Mechanisms
Provides a fast, powerful ejection stroke to push finished parts out of molds or fixtures quickly, improving overall machine cycle times.
Is the Airtac SAI100 Standard Air Cylinder SAI100BX15 the Right Cylinder?
Selecting this 100 mm bore over the smaller 80 mm variant significantly increases output, stepping up the 0.5 MPa push force from 2513 N to 3927 N. The 15 mm stroke is optimal for applications requiring rapid, high-impact actuation over a very short distance without occupying excessive machine space.
Because the standard SAI lacks an internal locking mechanism, it cannot hold a load safely if air pressure is lost; for fail-safe holding requirements, consider the SAIL or BSAI variants. As a dimensionally interchangeable ISO 15552 cylinder, this model serves as a direct drop-in replacement for other standard profile cylinders sharing the same 100 mm bore, 15 mm stroke, G1/2 port, and mounting accessories.
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.
