About the Airtac SAI40 Standard Air Cylinder SAI40AX170
The AirTAC SAI40X170 is a double-acting ISO 15552 profile cylinder featuring a 40mm bore and a 170mm stroke. It provides a push force of 628 N and a pull force of 528 N at 0.5 MPa, making it well-suited for mid-range automation tasks.
This specific configuration utilizes a SUS420J2 stainless steel piston rod (option A) for enhanced corrosion resistance compared to standard carbon steel. It features tapered PT threads and an extruded aluminum barrel with integrated sensor grooves on both sides, ready for CMSE or DMSE switches when a magnet is specified.

Where the Airtac SAI40 Standard Air Cylinder SAI40AX170 Is Used
Package Sorting
Provides reliable 628 N push force to divert packages of moderate weight on automated sorting lines.
Clamp Fixtures
Secures workpieces during machining operations, utilizing the 170mm stroke to accommodate varying part sizes.
Material Handling
Actuates gates and stops on assembly machinery, benefiting from the SUS420J2 rod's durability in humid environments.
Is the Airtac SAI40 Standard Air Cylinder SAI40AX170 the Right Cylinder?
Choose this 40mm bore when a 32mm bore (402 N push at 0.5 MPa) lacks the necessary thrust, but you want to avoid the larger footprint of a 50mm bore (982 N). For this 170mm stroke, ensure your mechanism handles side loads properly to prevent rod-bearing bending; utilizing an external guide rail is recommended if heavy off-center loads are present.
As a standard double-acting cylinder, this model relies on continuous air pressure to hold position and will drift if pressure is lost. If your application requires fail-safe load holding, consider the SAIL variant with an air-released lock. This unit serves as a direct replacement for other ISO 15552 profile cylinders, matching standard mounting interfaces and PT porting.
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 SAI40AX170 FAQ
