About the Airtac SAI40 Standard Air Cylinder SAI40AX140S
The AirTAC SAI40X140-S is a double-acting ISO 15552 profile cylinder offering 628 N of push force at 0.5 MPa and 879 N at 0.7 MPa. Its 140 mm stroke is ideal for mid-range automation tasks requiring reliable linear motion. The extruded aluminum barrel design omits tie rods, providing a clean exterior while maintaining strict dimensional interchangeability with other ISO 15552 cylinders.
This specific configuration includes a SUS420J2 stainless steel piston rod (material code A), which provides excellent corrosion resistance for humid or wash-down environments. Equipped with a magnet (-S), it supports direct mounting of CMSE or DMSE series sensor switches along the dual integrated grooves on the barrel. Fluid connections use a PT tapered thread on the G1/4 port.

Where the Airtac SAI40 Standard Air Cylinder SAI40AX140S Is Used
Component Clamping
Provides 879 N of push force at 0.7 MPa, securely holding workpieces during machining or assembly processes.
Package Diversion
The 140 mm stroke actuates diverter arms on packaging lines to route boxes efficiently without occupying excessive frame space.
Gate Control
Operates small access gates and machine guards, utilizing the SUS420J2 stainless steel rod to withstand industrial moisture.
Is the Airtac SAI40 Standard Air Cylinder SAI40AX140S the Right Cylinder?
Choose this 40 mm bore when an application demands more thrust than the 32 mm variant (402 N at 0.5 MPa) but lacks the physical envelope for a 50 mm cylinder (982 N at 0.5 MPa). The 140 mm stroke length strikes a balance for standard machine movements. For operations needing precise end-position holding without constant air pressure, a standard SAI will drift when exhaust occurs; in such cases, specify the SAIL variant with an air-released lock or utilize an external pilot-operated check valve.
As a true ISO 15552 profile cylinder, this model serves as a seamless direct replacement for any standard 40 mm bore, 140 mm stroke ISO cylinder. Ensure your setup matches the PT G1/4 port, utilizes appropriate FA/FB flange or LB foot mounting accessories, and leverages the -S magnet for necessary position feedback.
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.
