About the Airtac SAI40 Standard Air Cylinder SAI40AX130S
The AirTAC SAI40X130-S is a double-acting ISO 15552 profile cylinder engineered to deliver 628 N of push force at 0.5 MPa and 879 N at 0.7 MPa. Its 130 mm stroke provides the exact mid-range travel needed for compact ejection and clamping tasks. Because it adheres strictly to ISO 15552 mounting dimensions, this actuator serves as a direct replacement for any standard cylinder sharing this interface.
This specific configuration includes an -S magnet for direct compatibility with CMSE and DMSE reed switches, fitting neatly into the dual sensor grooves extruded along the aluminum barrel. Furthermore, the piston rod is constructed from SUS420J2 stainless steel, offering superior corrosion resistance compared to standard carbon steel. Fluid connections use PT tapered threads, ensuring tight, reliable pneumatic seals in demanding industrial environments.

Where the Airtac SAI40 Standard Air Cylinder SAI40AX130S Is Used
Part Ejection Systems
Uses the 879 N push force at 0.7 MPa to positively eject stamped metal parts from a die, with the 130 mm stroke clearing the press bed safely.
Diverting Arm Actuation
Drives a short-stroke diverter on a packaging line, where the SUS420J2 stainless rod resists minor moisture exposure during washdown cycles.
Clamp Fixtures
Secures workpieces in a machining fixture, utilizing the G1/4 port for rapid fill and exhaust to maintain high cycle rates.
Is the Airtac SAI40 Standard Air Cylinder SAI40AX130S the Right Cylinder?
Choose this 40 mm bore when an SAI32 unit lacks sufficient thrust (providing only 402 N at 0.5 MPa), but a larger 50 mm bore would be overkill. The 130 mm stroke is a non-standard length, which is fully supported within the 1200 mm maximum standard stroke limit for this bore size. To ensure accurate position feedback, pair the built-in magnet with CMSE or DMSE sensors.
If your machinery requires the load to remain securely held in place during a sudden loss of air pressure, do not rely on the standard adjustable air cushions, as they only decelerate the piston at stroke end. For true fail-safe load holding, specify the SAIL variant with an air-released lock, or integrate an external pilot-operated check valve into your circuit design.
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 SAI40AX130S FAQ
This 40 mm bore cylinder generates 628 N of push force and 528 N of pull force at 0.5 MPa. At 0.7 MPa, the push force increases to 879 N.
Yes, the SAI40X130-S is dimensionally interchangeable per ISO 15552. You can drop it in to replace other ISO 15552 profile cylinders with a 40 mm bore and 130 mm stroke, provided your porting matches the PT G1/4 connection.
