About the Airtac SAI40 Standard Air Cylinder SAI40BX10
The AirTAC SAI40X10 is a double-acting ISO 15552 profile cylinder featuring a 40mm bore and a highly specialized 10mm stroke. Because this stroke falls below standard manufacturing increments, it is produced as a made-to-order non-standard stroke to suit compact actuation needs. It delivers a push force of 628 N and a pull force of 528 N at 0.5 MPa, making it highly effective for short, powerful clamping or ejecting tasks.
This specific configuration is built with a SUS304 stainless steel piston rod (material code B), offering superior corrosion resistance for environments where standard carbon steel rods would degrade. The barrel features integrated sensor grooves on both sides for CMSE or DMSE switches, though a magnet (-S option) would need to be specified separately if position sensing is ever required.

Where the Airtac SAI40 Standard Air Cylinder SAI40BX10 Is Used
Short-Stroke Clamping
Ideal for holding delicate electronics or machined parts securely in a fixture using its 628 N push force over a tight 10mm travel distance.
Ejector Mechanism
Provides a rapid, short-range thrust to push completed components off a conveyor line without requiring a long physical footprint.
Corrosive Environment Actuation
The SUS304 stainless steel rod excels in food processing or chemical washdown zones where moisture would quickly rust standard carbon steel.
Is the Airtac SAI40 Standard Air Cylinder SAI40BX10 the Right Cylinder?
Selecting this 40mm bore cylinder makes sense when the 32mm variant (providing 402 N push at 0.5 MPa) lacks the necessary thrust, but a larger 50mm bore (982 N push) would be physically oversized for the machine envelope. The 10mm stroke is ideal for micro-movements where full piston travel must be restricted. For any application requiring the load to be physically held in place without continuous air pressure, note that the standard adjustable air cushions only decelerate the piston at stroke end and do not function as a mechanical lock; consider the SAIL variant with an air-released lock or an external pilot-operated check valve for those requirements.
As a genuine AirTAC component, it is dimensionally interchangeable per ISO 15552, serving as a direct replacement for other ISO 15552 profile cylinders. When ordering, confirm the PT tapered port thread type, the G1/4 port size, and any required mounting accessories such as an LB foot bracket or FA flange.
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 SAI40BX10 FAQ
At an operating pressure of 0.5 MPa, the SAI40X10 provides a push force of 628 N and a pull force of 528 N. At 0.7 MPa, the push force increases to 879 N.
Yes, the SAI40X10 is a true ISO 15552 profile cylinder, meaning its mounting dimensions are standardized for direct interchangeability with other ISO 15552 cylinders of the same bore size.
