About the Airtac SAI40 Standard Air Cylinder SAI40X90
The AirTAC SAI40X90 is a double-acting ISO 15552 profile cylinder featuring a 40mm bore and a 90mm stroke. It delivers a push force of 628 N and a pull force of 528 N at 0.5 MPa, making it a robust choice for moderate-duty automation. The extruded aluminum barrel design eliminates tie rods, providing a clean exterior that is dimensionally interchangeable with other ISO 15552 cylinders.
This specific configuration is built with a standard carbon steel piston rod and utilizes PT tapered port threads for reliable pneumatic connections. The barrel includes integrated sensor grooves on both sides, allowing for direct mounting of CMSE or DMSE series switches if you specify the -S magnet option in your build.

Where the Airtac SAI40 Standard Air Cylinder SAI40X90 Is Used
Package Diverting
Provides the 628N push force needed to rapidly divert medium-weight packages on a sorting line.
Clamping Fixtures
Ideal for securely holding workpieces in place during light machining or assembly processes.
Material Handling
Handles the actuation of small lifts and stops within automated warehousing systems.
Is the Airtac SAI40 Standard Air Cylinder SAI40X90 the Right Cylinder?
If your application requires less force, stepping down to a 32mm bore yields 402 N of push force at 0.5 MPa, whereas moving up to a 50mm bore provides 982 N. The 90mm stroke on this unit is ideal for short, rapid movements. Because the stroke is under 300mm, side-load stress on the rod bearing is minimal, though external guides are still recommended for heavy offset loads.
This standard SAI40X90 relies on live air pressure to maintain its position. If power is lost or the valve centers, the piston will drift. For applications requiring true position holding without continuous pressure, consider the SAIL variant with an air-released lock or the BSAI bidirectional clamp-lock. When ordering a replacement, verify the 40mm bore, 90mm stroke, G1/4 port, and your preferred mounting accessory such as an LB foot or FA flange.
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 SAI40X90 FAQ
