About the Airtac SAI40 Standard Air Cylinder SAI40BX100
The AirTAC SAI40X100 is a double-acting ISO 15552 profile cylinder offering 628 N push force at 0.5 MPa. Its 100 mm stroke is ideal for medium-duty handling and assembly tasks. The extruded aluminum barrel omits tie rods for a clean exterior.
This specific configuration features a SUS304 stainless steel piston rod (material code B) for superior corrosion resistance. It uses PT tapered port threads and lacks a magnet, meaning position sensing via CMSE or DMSE switches is not supported without modification. For high-temperature environments up to 70 C, the standard TPU seals handle the load, though Viton (H) alternatives exist.

Where the Airtac SAI40 Standard Air Cylinder SAI40BX100 Is Used
Assembly Jigs
Provides 879 N of thrust at 0.7 MPa for clamping parts during machining or fastening operations.
Package Diverting
The 100 mm stroke actuates pusher arms to redirect small to medium packages on material handling lines.
Pallet Stops
Deploys a physical stop block to halt pallets at specific workstations before retracting.
Is the Airtac SAI40 Standard Air Cylinder SAI40BX100 the Right Cylinder?
If 628 N at 0.5 MPa is insufficient, stepping up to the 50 mm bore yields 982 N of push force. Conversely, smaller 32 mm bore drops output to 402 N. Because this 100 mm stroke is under the 300 mm side-load threshold, standard mounting accessories like FA flanges or LB foot brackets are fully sufficient without external guides.
This model is dimensionally interchangeable per ISO 15552, serving as a direct replacement for other ISO 15552 profile cylinders. Note 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 SAI40 Standard Air Cylinder SAI40BX100 FAQ
At 0.5 MPa, the push force is 628 N and the pull force is 528 N. At 0.7 MPa, the push force increases to 879 N.
Yes. The SAI40X100 is a true ISO 15552 profile cylinder, making its mounting interface and center-to-center dimensions directly interchangeable with other standard ISO 15552 cylinders.
