About the Airtac SAI40 Standard Air Cylinder SAI40BX10S
The AirTAC SAI40X10-S is a double-acting ISO 15552 profile cylinder engineered for ultra-short stroke actuation. Delivering a push force of 628 N at 0.5 MPa, it integrates a SUS304 stainless steel piston rod (code B) for superior corrosion resistance in washdown or chemically active settings. The integrated magnet (-S) enables direct mounting of CMSE or DMSE position switches along the dual sensor grooves.
This 10 mm stroke configuration is purpose-built for high-cycle clamping, ejection, or gating tasks where absolute minimal extension is paramount. It features a PT tapered port thread and adjustable air cushions at both ends to mitigate impact forces, ensuring reliable performance even in rapid cycling operations.

Where the Airtac SAI40 Standard Air Cylinder SAI40BX10S Is Used
Short-Stroke Part Ejection
Ideal for knocking finished parts out of machining fixtures within extremely confined machinery envelopes.
Sorting Diverter Gates
Provides rapid, high-force actuation for pneumatic routing gates on high-speed packaging conveyors.
Pallet Stop Blocks
Acts as a compact, robust physical stop mechanism to arrest pallet movement on handling lines.
Is the Airtac SAI40 Standard Air Cylinder SAI40BX10S the Right Cylinder?
Choose this 40 mm bore variant when a 32 mm bore (402 N push at 0.5 MPa) lacks the necessary thrust for your clamping or lifting task, but a 50 mm bore (982 N push) would be physically oversized. The 10 mm stroke is optimal for tight-space ejection and part holding. Because the stroke is minimal, side-load stress on the rod bearing is negligible compared to longer strokes. If your workflow demands position retention during a complete loss of pneumatic pressure, this standard cylinder will drift; integrate an external pilot-operated check valve or specify the SAIL locking variant for fail-safe load holding. This unit is dimensionally interchangeable per ISO 15552 standards, offering a direct replacement for other ISO 15552 profile cylinders.

- ✓ 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.
