About the Airtac SAI40 Standard Air Cylinder SAI40AX180S
The AirTAC SAI40X180-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. With a 180 mm stroke, it provides the precise mid-range travel required for packaging equipment and automated assembly lines. The extruded aluminum barrel design omits tie rods, ensuring a clean exterior that resists contamination.
This specific configuration includes a SUS420J2 stainless steel piston rod (material code A) for superior corrosion resistance in humid or mildly chemically washed environments. It features PT tapered port threads and is equipped with a magnet (-S) for seamless integration with CMSE or DMSE reed switches in the dual-side sensor grooves.

Where the Airtac SAI40 Standard Air Cylinder SAI40AX180S Is Used
Component Pick-and-Place
Ideal for moving electronic components or small machined parts on a 180 mm travel axis, utilizing the 879 N push force at 0.7 MPa to securely lift and transfer payloads.
Packaging Diverters
Drives sorting gates and diverter arms on packaging conveyors, where the SUS420J2 stainless steel rod withstands occasional washdowns and maintains smooth actuation.
Material Clamping
Provides reliable holding pressure for light material clamping fixtures during secondary machining or labeling processes, benefiting from the integrated -S magnet for position confirmation.
Is the Airtac SAI40 Standard Air Cylinder SAI40AX180S the Right Cylinder?
Choose this 40 mm bore when an application requires more thrust than the 32 mm variant (which provides 402 N at 0.5 MPa) but does not warrant the larger footprint and air consumption of the 50 mm bore (982 N at 0.5 MPa). The 180 mm stroke falls well within the 1200 mm standard maximum, making it a readily available, non-custom stroke length.
Because the stroke is under 300 mm, side-load stress on the rod bearing is minimal, though external guides are still recommended if absorbing lateral impact. For any mechanism that must hold a load securely during a complete air pressure loss, note that the standard adjustable air cushions only decelerate the piston at stroke end and do not act as a brake; instead, specify the SAIL locking variant or an external pilot-operated check valve. As a dimensionally interchangeable ISO 15552 profile cylinder, it serves as a direct replacement for other ISO 15552 cylinders, requiring only a G1/4 port connection and standard FA or FB flange mount 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.
