About the Airtac SAI40 Standard Air Cylinder SAI40X150S
The AirTAC SAI40X150-S is a double-acting ISO 15552 profile cylinder featuring a 40mm bore and 150mm stroke. It generates 879N of push force at 0.7 MPa, making it well-suited for mid-range industrial actuation tasks.
Equipped with a magnet (-S), this unit operates seamlessly with CMSE or DMSE sensor switches fitted into the dual side grooves of the extruded aluminum barrel. The standard carbon steel piston rod provides robust durability for high-cycle automation environments.

Where the Airtac SAI40 Standard Air Cylinder SAI40X150S Is Used
Automated Clamping
Provides 879N of push force at 0.7 MPa to secure medium-sized workpieces during CNC machining or welding operations.
Package Diverting
The 150mm stroke extends quickly at speeds up to 800 mm/s to push cartons off a main conveyor belt onto secondary packaging lines.
Material Ejection
Uses the 528N pull force at 0.5 MPa to retract and pull formed parts out of molds or stamping presses reliably.
Is the Airtac SAI40 Standard Air Cylinder SAI40X150S the Right Cylinder?
Select this 40mm bore when an application requires more power than a 32mm cylinder (which offers only 563N at 0.7 MPa) but lacks the physical space for a 50mm unit. The 150mm stroke provides ample extension for indexing and clamping operations.
Because this is a double-acting pneumatic actuator, it requires continuous air pressure to hold a load; exhausting the air or centering the valve will cause the piston to drift. For applications needing static position holding without live pressure, consider the SAIL variant with an air-released lock. As a dimensionally interchangeable ISO 15552 component, it serves as a direct drop-in replacement for other standard profile cylinders using PT port threads and standard FA or LB mounting accessories.
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 SAI40X150S FAQ
