About the Airtac SAI40 Standard Air Cylinder SAI40AX10
The AirTAC SAI40X10 is a double-acting ISO 15552 profile cylinder engineered for compact actuation, delivering a push force of 628 N at 0.5 MPa. Its 10 mm stroke is optimal for short-travel clamping, ejection, or positioning tasks where space is highly restricted.
This specific configuration features a SUS420J2 stainless steel rod (material code A) for superior corrosion resistance compared to standard carbon steel. It utilizes a PT tapered port thread and lacks a magnet, making it ideal for basic pneumatic motion without sensor detection requirements.

Where the Airtac SAI40 Standard Air Cylinder SAI40AX10 Is Used
Short-Stroke Clamping
Ideal for holding lightweight workpieces securely during machining or assembly operations within confined fixture spaces.
Product Diverting
Provides rapid, short-travel actuation to push or divert small packages on a conveyor line without occupying much room.
Ejection Stations
Delivers precise 10 mm ejection strokes to push finished parts out of jigs or testing fixtures efficiently.
Is the Airtac SAI40 Standard Air Cylinder SAI40AX10 the Right Cylinder?
Choose this 40 mm bore when a 32 mm bore (402 N at 0.5 MPa) lacks sufficient thrust, but a 50 mm bore (982 N at 0.5 MPa) is physically too large. Because the stroke is only 10 mm, side-load stress on the rod bearing is minimal, eliminating the need for external guides.
For any application requiring the load to remain held without continuous air pressure, do not rely on the standard cushions. Instead, specify an SAIL (air-released lock) or BSAI (clamp-lock) variant. To ensure seamless ISO 15552 interchangeability, match the 40 mm bore, 10 mm stroke, PT G1/4 port, and appropriate mounting accessory like an 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.
