About the Airtac SAI40 Standard Air Cylinder SAI40AX500S
The AirTAC SAI40X500-S is a double-acting ISO 15552 profile cylinder featuring a 40mm bore and a 500mm stroke. It generates 628N of push force and 528N of pull force at 0.5 MPa, making it a solid choice for mid-range linear actuation tasks.
This variant includes a magnet for position sensing via CMSE or DMSE switches fitted into the dual sensor grooves on the extruded aluminum barrel. It is built with an SUS420J2 stainless steel rod for enhanced corrosion resistance and utilizes PT tapered port threads.

Where the Airtac SAI40 Standard Air Cylinder SAI40AX500S Is Used
Package Sorting
Ideal for pushing diverters on packaging lines, utilizing the integrated magnet and 500mm stroke to route boxes efficiently.
Material Handling
Moves lightweight jigs and fixtures along assembly tracks, benefiting from the 30-800 mm/s operating speed range.
Pallet Positioning
Stops or indexes pallets at processing stations, taking advantage of the SUS420J2 stainless steel rod for durability.
Is the Airtac SAI40 Standard Air Cylinder SAI40AX500S the Right Cylinder?
If your application requires slightly less force, stepping down to the 32mm bore yields 402N of push force at 0.5 MPa. For heavier loads, moving up to the 50mm bore provides 982N. Because this model has a 500mm stroke, long unsupported rods are susceptible to bending under side loads; using an external guide rail or a guided cylinder carriage is strongly recommended to prevent premature rod-bearing wear.
As a true ISO 15552 profile cylinder, it serves as a direct replacement for any standard 40mm bore, 500mm stroke ISO 15552 unit. It uses a PT G1/4 port and standard mounting accessories like FA or FB flanges. Note that this standard cylinder does not hold its load when air pressure is lost; if fail-safe holding is required, consider the SAIL or BSAI locking variants.
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 SAI40AX500S FAQ
At an operating pressure of 0.5 MPa, this 40mm bore cylinder provides 628N of push force and 528N of pull force. At 0.7 MPa, the push force increases to 879N.
Yes. The SAI series is a genuine ISO 15552 profile cylinder, meaning its mounting dimensions are fully interchangeable with other standard ISO 15552 cylinders of the same bore and stroke. Just ensure your port matches the G1/4 thread.
