About the Airtac SAI100 Standard Air Cylinder SAI100BX105
The AirTAC SAI100X105 is a double-acting ISO 15552 profile cylinder featuring a 100mm bore and 105mm stroke. It delivers a robust 3927 N push force at 0.5 MPa, making it well-suited for heavy-duty positioning tasks. This extruded aluminum barrel design omits tie-rods for a clean exterior while maintaining strict standardized mounting dimensions.
Built for demanding environments, this specific configuration includes a SUS304 stainless steel piston rod for superior corrosion resistance. It utilizes PT tapered port threads and lacks a standard magnet, meaning it does not directly support reed sensors like CMSE or DMSE without modification.

Where the Airtac SAI100 Standard Air Cylinder SAI100BX105 Is Used
Heavy Stamping
Provides the high kinetic energy needed to drive stamping and forming presses in metal fabrication lines.
Plastic Molding
Actuates large mold halves or heavy ejector mechanisms where a 3927 N push force at 0.5 MPa is required.
Pallet Handling
Pushes or diverts heavy loaded pallets on conveyor lines, utilizing its robust 100mm bore capacity.
Is the Airtac SAI100 Standard Air Cylinder SAI100BX105 the Right Cylinder?
If your application requires slightly less force, stepping down to an 80mm bore yields 2513 N at 0.5 MPa, while moving up to a 125mm bore provides 6136 N for heavier loads. Because this 105mm stroke is relatively short, side-load stress on the rod bearing is minimal compared to longer strokes.
As a standard double-acting cylinder, the SAI100X105 relies on continuous air pressure to maintain its position. If air is exhausted or the valve is centered, the piston will drift. For applications requiring dead-load holding without live pressure, consider the SAIL (air-released lock) or BSAI (clamp-lock) variants. This model serves as a dimensionally interchangeable drop-in replacement for any ISO 15552 cylinder with matching 100mm bore, 105mm stroke, PT G1/2 ports, and compatible 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 SAI100BX105 FAQ
At a 0.5 MPa operating pressure, this 100mm bore cylinder provides 3927 N of push force and 3681 N of pull force. At 0.7 MPa, the push force increases to 5497 N.
Yes, the SAI100X105 is a genuine ISO 15552 profile cylinder, making its mounting interface dimensionally interchangeable with other ISO 15552 cylinders of the same bore and stroke. It is not a tie-rod design and uses PT G1/2 ports.
