About the Airtac SAI40 Standard Air Cylinder SAI40AX175
The AirTAC SAI40X175 is a double-acting ISO 15552 profile cylinder engineered to deliver 879 N of push force at 0.7 MPa. Its 175 mm stroke provides the extended travel needed for mid-distance positioning tasks without sacrificing a compact footprint.
Built with a SUS420J2 stainless steel piston rod (material code A), this unit offers superior corrosion resistance compared to standard carbon steel. It features PT tapered port threading and utilizes an extruded aluminum barrel, ensuring true dimensional interchangeability with other ISO 15552 standard actuators.

Where the Airtac SAI40 Standard Air Cylinder SAI40AX175 Is Used
Component Clamping
Provides 628 N of push force at 0.5 MPa to securely hold aluminum or steel workpieces during CNC machining and milling operations.
Package Diverting
The 175 mm stroke actuates diverter arms on packaging lines, moving cartons between parallel conveyor belts at speeds up to 800 mm/s.
Gate Operation
Cycles material handling gates and access doors in automated assembly cells, utilizing the SUS420J2 rod to resist moisture in factory environments.
Is the Airtac SAI40 Standard Air Cylinder SAI40AX175 the Right Cylinder?
Select this 40 mm bore when an application requires stepping up from the 32 mm class (which provides 563 N at 0.7 MPa) to handle heavier payloads. The 175 mm stroke is well below the 1200 mm maximum standard stroke for this bore, keeping the assembly rigid. Because the piston rod is unsupported for a significant portion of its travel, avoid applying heavy lateral loads directly to the rod tip; use an external guide rail to prevent premature bearing wear.
This model uses a G1/4 PT port and can be configured with various mounting accessories like FA flanges or TC trunnions. Note that a standard SAI cylinder relies on continuous air pressure to maintain its position; if the air supply is lost, the load will drift. For dead-load holding, consider the SAIL variant with an air-released lock.
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 SAI40AX175 FAQ
At an operating pressure of 0.7 MPa, this 40 mm bore cylinder generates 879 N of push force and 724 N of pull force. At 0.5 MPa, the push force is 628 N.
Yes. The SAI40X175 is a true ISO 15552 profile cylinder, making it dimensionally interchangeable with other ISO 15552 cylinders of the same bore and stroke. You can swap it directly using the existing mounting interface.
