About the Airtac SAI40 Standard Air Cylinder SAI40AX80
The AirTAC SAI40X80 is a double-acting ISO 15552 profile cylinder featuring a 40mm bore and an 80mm stroke. It delivers a push force of 628 N and a pull force of 528 N at 0.5 MPa, making it well-suited for medium-duty handling tasks. 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 is built with a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance in demanding environments. It utilizes PT tapered port threads and lacks a standard magnet, meaning it is not immediately ready for proximity sensor switches unless specified otherwise. For applications requiring higher heat resistance, the standard TPU seals can be swapped for Viton (H) or NBR (N) options.

Where the Airtac SAI40 Standard Air Cylinder SAI40AX80 Is Used
Parts Clamping
Ideal for securing medium-weight workpieces during machining or assembly operations, utilizing its 628N push force for stable, precise holding.
Package Diverting
Well-suited for short-stroke diverting arms on packaging lines, where the 80mm stroke quickly redirects goods without taking up excessive space.
Gate Control
Operates small access gates or machine guards, providing reliable linear actuation that withstands industrial environments thanks to the SUS420J2 rod.
Is the Airtac SAI40 Standard Air Cylinder SAI40AX80 the Right Cylinder?
Selecting this 40mm bore over the smaller 32mm variant increases your thrust from 402 N to 628 N at 0.5 MPa, providing a significant power upgrade without a massive footprint increase. If your application requires less force, stepping down to the 32mm bore is an option. With an 80mm stroke, this model offers a compact extension that avoids the severe side-load bending moments seen in longer strokes, though external guides are always recommended if lateral loads are present.
Because this is a standard double-acting cylinder, it will not hold a load in place if air pressure is lost or the valve is centered; the piston will drift. For critical position-holding needs without live pressure, consider the SAIL (air-released lock) or BSAI (clamp-lock) variants. This model uses a G1/4 port, PT thread type, and is fully interchangeable with standard ISO 15552 mounting accessories like FA flanges or LB foot brackets.
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 SAI40AX80 FAQ
