About the Airtac SAI100 Standard Air Cylinder SAI100BX125S
The AirTAC SAI100X125-S is a double-acting ISO 15552 profile cylinder offering a robust 5497 N push force at 0.7 MPa. With a 100 mm bore and 125 mm stroke, it provides the extended travel and high thrust needed for heavy-duty industrial positioning. The extruded aluminum barrel design omits tie rods for a clean exterior.
This specific configuration includes a SUS304 stainless steel piston rod (material code B) for superior corrosion resistance in harsh environments. It features PT tapered port threads and is equipped with a magnet (-S) to seamlessly integrate with CMSE or DMSE sensor switches along the dual-side mounting grooves.

Where the Airtac SAI100 Standard Air Cylinder SAI100BX125S Is Used
Heavy Metal Stamping
Provides the 5497 N output force required to securely hold and stamp thick metal sheets in automated fabrication lines.
Pallet Diverting
Actuates heavy-duty diverter arms on conveyor systems, utilizing the 125 mm stroke to push loaded pallets onto secondary routing tracks.
Plastic Mold Ejection
Delivers consistent ejection force to release large molded plastic parts from injection machinery, relying on the corrosion-resistant SUS304 rod.
Is the Airtac SAI100 Standard Air Cylinder SAI100BX125S the Right Cylinder?
Select this 100 mm bore cylinder when an 80 mm bore (providing 3518 N at 0.5 MPa) lacks the necessary thrust, but you want to avoid stepping up to a 125 mm bore (8590 N at 0.5 MPa) which may demand excessive air volume. The 125 mm stroke offers moderate travel without requiring external side-load guides.
As a true ISO 15552 profile cylinder, it serves as a direct dimensional drop-in replacement for other ISO 15552 standard cylinders. Remember that the adjustable air cushions only decelerate the piston near stroke ends; they do not hold loads. If your application requires position holding without air pressure, consider the SAIL locking variant or an external rod lock.
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 SAI100BX125S FAQ
At a standard operating pressure of 0.7 MPa, this 100 mm bore cylinder generates 5497 N of push force and 5184 N of pull force. It can reach a maximum theoretical force of 801 kgf at 1.0 MPa.
Yes. The SAI100X125-S is manufactured to the ISO 15552 profile standard, making its mounting interface and dimensions fully interchangeable with other ISO 15552 cylinders of the same bore size.
