About the Airtac SAI100 Standard Air Cylinder SAI100BX70
The AirTAC SAI100X70 is a double-acting ISO 15552 profile cylinder engineered for high-force automation tasks. It generates a substantial 3927 N of push force at just 0.5 MPa, extending up to 70 mm to drive heavy-duty clamping and lifting mechanisms.
This specific configuration utilizes a highly corrosion-resistant SUS304 stainless steel piston rod and PT tapered port threads. The extruded aluminum barrel features sensor grooves on both sides, allowing for direct mounting of CMSE or DMSE switches if a magnet is added later.

Where the Airtac SAI100 Standard Air Cylinder SAI100BX70 Is Used
Heavy-Duty Stamping
Provides the robust 3927 N push force required to operate mechanical stamping and forming presses in metal fabrication lines.
Pallet Diverter
Acts as a high-power diverter arm on heavy-load conveyor systems, reliably redirecting large pallets without stalling.
Injection Molding Extraction
Utilizes its 70 mm stroke and SUS304 rod to extract heavy molded parts from injection machines, resisting high ambient temperatures.
Is the Airtac SAI100 Standard Air Cylinder SAI100BX70 the Right Cylinder?
Selecting this 100 mm bore over the smaller 80 mm variant provides a significant thrust upgrade, stepping up from 2513 N to 3927 N at 0.5 MPa. If your application requires less energy, dropping to the 80 mm bore saves space and air consumption.
Because this is a double-acting cylinder, it relies on continuous air pressure to move and hold its load. If your machinery loses air supply or the valve centers, the piston will drift. For fail-safe load holding, consider the SAIL variant with an air-released lock or an external rod lock. As a true ISO 15552 profile cylinder, it serves as a dimensionally interchangeable drop-in replacement for competing ISO 15552 cylinders, utilizing a G1/2 port and standard 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.
Airtac SAI100 Standard Air Cylinder SAI100BX70 FAQ
At a 0.5 MPa operating pressure, the SAI100X70 generates 3927 N of push force and 3681 N of pull force. If pressure is increased to 0.7 MPa, the push force reaches 5497 N.
Yes. The SAI100X70 is a genuine ISO 15552 profile cylinder, meaning its mounting interface and envelope dimensions are interchangeable with other ISO 15552 standard cylinders, making it a seamless drop-in replacement.
