About the Airtac SAI40 Standard Air Cylinder SAI40AX475S
The AirTAC SAI40X475-S is a double-acting ISO 15552 profile cylinder engineered for automated equipment requiring a 475mm stroke. It generates 628N of push force at 0.5 MPa and features a built-in magnet for CMSE and DMSE sensor integration. The extruded aluminum barrel design omits tie rods, providing a clean exterior that simplifies mounting and accessory attachment.
This specific configuration uses a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance compared to standard carbon steel. It also utilizes PT tapered port threads. Operating at speeds up to 800mm/s, it accommodates standard stroke lengths up to 1200mm, making this 475mm iteration a versatile choice for mid-range linear actuation tasks.

Where the Airtac SAI40 Standard Air Cylinder SAI40AX475S Is Used
Package Diversion
Ideal for actuating sorting arms on packaging lines where the 475mm stroke pushes products cleanly between adjacent conveyor belts.
Vertical Lifting Gate
Provides the necessary extension to raise and lower lightweight access gates or safety barriers in material handling workcells.
Component Indexing
Moves workpieces precisely down an assembly line track, utilizing the 628N push force to overcome slight sliding friction.
Is the Airtac SAI40 Standard Air Cylinder SAI40AX475S the Right Cylinder?
Select this 40mm bore when an application requires more thrust than a 32mm cylinder (402N at 0.5 MPa) but lacks the physical space for a 50mm unit (982N at 0.5 MPa). The 475mm stroke provides ample extension for indexing and lifting tasks. Because the stroke exceeds 300mm, the unsupported rod length is susceptible to bending under side loads; utilizing an external guide rail or a guided cylinder mechanism is strongly recommended to prevent premature rod-bearing wear.
As a true ISO 15552 profile cylinder, this unit serves as a direct replacement for any standard 40mm bore cylinder with a 475mm stroke. It uses a PT G1/4 port, accepts standard FA/FB flanges or LB foot mounts, and the -S suffix confirms the internal magnet is present for position sensing. Note that this standard cylinder does not hold loads pneumatically; if air pressure drops, the piston will drift, requiring an external check valve or a SAIL locking variant for fail-safe positioning.
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 SAI40AX475S FAQ
At a standard operating pressure of 0.5 MPa, this 40mm bore cylinder provides 628N of push force and 528N of pull force. It can reach 879N push force at 0.7 MPa.
Yes, the SAI40X475-S is dimensionally interchangeable per ISO 15552. You can drop it into existing machinery designed for standard 40mm profile cylinders, matching the G1/4 port and standard mounting dimensions.
