About the Airtac SAI40 Standard Air Cylinder SAI40AX190
The AirTAC SAI40X190 is a double-acting ISO 15552 profile cylinder featuring a 40mm bore and a 190mm stroke. It generates 628 N of push force at 0.5 MPa, extending to 879 N at 0.7 MPa, making it well-suited for medium-duty handling tasks. The extruded aluminum barrel design omits tie rods, providing a clean exterior that drops directly into standard ISO 15552 mounting interfaces.
Built for demanding environments, this specific configuration incorporates an SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance compared to standard carbon steel. It utilizes a PT tapered port thread and lacks a standard magnet, meaning it is ready for mechanical actuation but will not trigger reed sensors like the CMSE or DMSE series without modification.

Where the Airtac SAI40 Standard Air Cylinder SAI40AX190 Is Used
Part Ejection
Uses the 879 N push force at 0.7 MPa to reliably knock finished machined components out of a fixture across a 190mm travel distance.
Package Diverting
Actuates a routing gate on a packaging line, leveraging the 30-800 mm/s speed range to keep product flow moving without bottlenecks.
Material Pressing
Applies consistent downward pressure for light-duty assembly tasks, taking advantage of the SUS420J2 stainless rod in environments with occasional moisture.
Is the Airtac SAI40 Standard Air Cylinder SAI40AX190 the Right Cylinder?
Select this 40mm bore when your application requires more power than the 32mm variant (which provides only 402 N at 0.5 MPa) but does not need the full 982 N push force of the 50mm class. The 190mm stroke offers ample travel for part ejection or gating. If your assembly demands position holding during a power loss, remember that the standard adjustable air cushions only decelerate the piston at stroke ends and do not act as a brake; you would need to specify the SAIL variant for a pneumatic lock or the BSAI for a clamp-lock.
Because this 190mm stroke is below the 300mm threshold, side-load stress on the rod bearing is moderate, but you should still ensure proper alignment to prevent premature seal wear. This model is dimensionally interchangeable with other ISO 15552 cylinders, featuring a G1/4 port, M12x1.25 rod thread, and compatibility with FA/FB flange or LB foot 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 SAI40AX190 FAQ
This 40mm bore cylinder provides a push force of 628 N at 0.5 MPa and 879 N at 0.7 MPa. The pull force is 528 N at 0.5 MPa due to the rod displacement.
Yes, the SAI40X190 is a true ISO 15552 profile cylinder, meaning its mounting dimensions are standardized and it serves as a direct replacement for other ISO 15552 cylinders of the same bore size.
