About the Airtac SAI100 Standard Air Cylinder SAI100BX125
The AirTAC SAI100X125 is a double-acting ISO 15552 profile cylinder engineered for high-force linear motion. It generates 3927 N of push force at 0.5 MPa, scaling up to 5497 N at 0.7 MPa, making it well-suited for heavy-duty pressing and clamping over its 125 mm stroke.
Built with a SUS304 stainless steel piston rod (option B), this variant provides excellent corrosion resistance for demanding environments. It features a PT tapered port thread and an extruded aluminum barrel with dual sensor grooves, allowing direct mounting of CMSE or DMSE switches when a magnet is specified.

Where the Airtac SAI100 Standard Air Cylinder SAI100BX125 Is Used
Heavy-Duty Stamping
Provides the robust 3927 N push force at 0.5 MPa needed to form, stamp, or pierce metal components securely in automated production lines.
Pallet Diverting
Handles the high side-load momentum of heavy pallets on conveyor systems, using its 125 mm stroke to push heavy loads onto branching tracks.
Industrial Clamping
Exerts strong, reliable clamping pressure to hold large workpieces stationary during aggressive machining or welding operations.
Is the Airtac SAI100 Standard Air Cylinder SAI100BX125 the Right Cylinder?
Select this 100 mm bore when 50 mm (982 N at 0.5 MPa) lacks the necessary thrust for heavy manipulation, but before stepping to the massive 125 mm (6136 N) size. Its 125 mm stroke offers moderate extension without the side-load complexities of longer travels.
As an ISO 15552 profile cylinder, it serves as a direct dimensional drop-in replacement for other standard 100 mm bore actuators. Ensure you match the PT G1/2 port, mounting accessory (like FA flange or TC trunnion), and add the -S magnet if position sensing is required. Note that this standard cylinder relies on live air pressure to maintain its position; it will drift if pressure is lost, so consider the SAIL or BSAI locking variants if fail-safe holding is mandatory.
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 SAI100BX125 FAQ
At 0.5 MPa operating pressure, the SAI100X125 generates 3927 N of push force and 3681 N of pull force. If pressure is increased to 0.7 MPa, the push force rises to 5497 N.
Yes, the SAI100X125 is a genuine ISO 15552 profile cylinder, meaning its mounting interface and physical dimensions are interchangeable with other ISO 15552 standard cylinders of the same bore size.
