About the Airtac SAI40 Standard Air Cylinder SAI40AX225S
The AirTAC SAI40X225-S is a double-acting ISO 15552 profile cylinder engineered to deliver 628 N of push force and 528 N of pull force at 0.5 MPa. Its 225 mm stroke provides the extended travel needed for mid-range material handling and indexing tasks. As a genuine AirTAC component, it ensures dimensionally interchangeable mounting per ISO 15552 standards.
This specific configuration includes a magnetic piston (-S) for use with CMSE and DMSE position sensors, which seat neatly into the dual sensor grooves machined into the extruded aluminum barrel. To withstand harsher environments, the piston rod is constructed from SUS420J2 stainless steel (material code A), and the fluid ports feature a PT tapered thread design.

Where the Airtac SAI40 Standard Air Cylinder SAI40AX225S Is Used
Package Sorting Diverter
Provides the 628 N push force required to deflect medium-weight parcels on a high-speed sorting conveyor.
Clamping Fixture
Extends 225 mm to secure automotive components during machining, using the magnetic piston for position confirmation.
Pallet Stopper Gate
Acts as a pneumatic stop in automated storage systems, withstanding repeated impacts thanks to the SUS420J2 rod.
Is the Airtac SAI40 Standard Air Cylinder SAI40AX225S the Right Cylinder?
Select this 40 mm bore model when an application requires more thrust than a 32 mm bore (which provides 402 N at 0.5 MPa) but does not warrant the larger footprint of a 50 mm bore (982 N at 0.5 MPa). Because the 225 mm stroke exceeds 300 mm, it is crucial to manage potential side loading; use external guide rails or a guided cylinder to prevent rod-bearing bending and premature seal wear.
This profile cylinder acts as a direct replacement for other ISO 15552 cylinders, matching the exact bore, stroke, PT G1/4 port, and mounting accessory dimensions (such as LB foot or FA flange). Note that the standard adjustable air cushions only decelerate the piston at stroke ends; if the application must hold a load vertically without live air pressure, integrate an external pilot-operated check valve or specify the SAIL locking variant.
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 SAI40AX225S FAQ
At an operating pressure of 0.5 MPa, this double-acting cylinder generates a push force of 628 N and a pull force of 528 N. At 0.7 MPa, the push force increases to 879 N.
Yes, the SAI40X225-S is dimensionally interchangeable with other ISO 15552 profile cylinders. You can swap it directly by matching the 40 mm bore, 225 mm stroke, G1/4 port, and mounting hardware.
