About the Airtac SAI40 Standard Air Cylinder SAI40AX165S
The AirTAC SAI40X165-S is a double-acting ISO 15552 profile cylinder engineered to deliver 879 N of push force at 0.7 MPa. Its 165 mm stroke provides the exact mid-range extension needed for compact assembly machinery and material handling tasks. As a genuine AirTAC component, it ensures reliable pneumatic performance.
This specific configuration includes a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance in humid environments. It is equipped with a magnetic piston (-S) to seamlessly integrate with CMSE or DMSE reed switches via the dual sensor grooves on the extruded aluminum barrel. Fluid ports feature a PT tapered thread type.

Where the Airtac SAI40 Standard Air Cylinder SAI40AX165S Is Used
Assembly Tooling
Drives small clamps and positioning stops in automated assembly cells where 628 N of push force at 0.5 MPa is sufficient.
Package Diverting
Actuates routing gates and pusher arms on packaging lines, utilizing the 165 mm stroke to clear product profiles efficiently.
Material Handling
Lifts and transfers lightweight bins using magnetic position sensing to confirm end-of-stroke placement for the PLC.
Is the Airtac SAI40 Standard Air Cylinder SAI40AX165S the Right Cylinder?
Choose this 40 mm bore when an application requires more power than a 32 mm bore (which provides 563 N at 0.7 MPa) but lacks the physical space for a 50 mm option. The 165 mm stroke hits a sweet spot for standard pick-and-place operations without excessive retraction length.
Because this is a standard double-acting cylinder, it relies entirely on continuous air pressure to maintain its position. If air is lost or exhausted, the rod will drift. For applications requiring dead-end holding or drop protection, consider the SAIL variant with an air-released lock. Being dimensionally interchangeable per ISO 15552, it serves as a direct replacement for other ISO 15552 profile cylinders of the same bore and stroke.
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 SAI40AX165S FAQ
At a standard operating pressure of 0.5 MPa, this 40 mm bore cylinder provides 628 N of push force and 528 N of pull force. At 0.7 MPa, the push force increases to 879 N.
Yes. The SAI40X165-S is built to the ISO 15552 standard, making its mounting dimensions and interface fully interchangeable with other ISO 15552 profile cylinders of the same bore size.
