About the Airtac SAI40 Standard Air Cylinder SAI40AX15S
The AirTAC SAI40X15-S is a double-acting ISO 15552 profile cylinder engineered for compact actuation. It provides a push force of 628 N and a pull force of 528 N at 0.5 MPa. The 15 mm stroke is optimal for clamping, ejection, or short gripping tasks where space is strictly limited.
This specific configuration features an SUS420J2 stainless steel rod (material code A) for superior corrosion resistance compared to standard carbon steel. It includes a built-in magnet (-S) for seamless integration with CMSE or DMSE sensor switches along the dual grooves of the extruded aluminum barrel, and utilizes PT tapered port threading.

Where the Airtac SAI40 Standard Air Cylinder SAI40AX15S Is Used
Short-Stroke Clamping
Ideal for holding lightweight components firmly in place during machining or assembly with its 628 N push force.
Package Diverting
Provides rapid actuation for small diverters or gating mechanisms on packaging lines within tight spatial constraints.
Ejection Stations
Delivers quick, repetitive ejection of finished parts from press beds or molding machines using its 15 mm stroke.
Is the Airtac SAI40 Standard Air Cylinder SAI40AX15S the Right Cylinder?
Select this 40 mm bore when a 32 mm bore (402 N push at 0.5 MPa) lacks sufficient thrust, but you want to avoid the larger footprint of a 50 mm bore (982 N push at 0.5 MPa). The 15 mm stroke excels in high-cycle, short-throw automation. Because the stroke is short, side-load stress on the rod bearing is minimal compared to longer strokes. This cylinder is dimensionally interchangeable per ISO 15552, serving as a direct replacement for other ISO 15552 profile cylinders. To match this exact unit, specify the 40 mm bore, 15 mm stroke, PT port, and the -S magnet option.
Note that the standard double-acting SAI does not hold position if air pressure is lost; the piston will drift. For applications requiring pneumatic locking without live pressure, consider the SAIL or BSAI variants.
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 SAI40AX15S FAQ
