About the Airtac SAI40 Standard Air Cylinder SAI40BX475
The AirTAC SAI40X475 is a double-acting ISO 15552 profile cylinder engineered to deliver 628 N of push force at 0.5 MPa. Featuring a 40 mm bore and a 475 mm stroke, this extruded aluminum barrel unit is designed for substantial extension tasks requiring reliable linear motion.
This specific configuration includes a SUS304 stainless steel rod (code B) for superior corrosion resistance and utilizes PT tapered port threads. Without a built-in magnet, it relies on external physical switching, while the adjustable air cushions at both ends ensure smooth deceleration across the 30-800 mm/s speed range.

Where the Airtac SAI40 Standard Air Cylinder SAI40BX475 Is Used
Package Diversion
Extends 475 mm to push heavy cartons across transfer lines with 628 N of force at 0.5 MPa.
Component Stamping
Drives light-duty stamping or marking presses where the SUS304 rod prevents corrosion in humid environments.
Pallet Positioning
Pushes empty pallets into loading zones using the full stroke length and adjustable end cushions.
Is the Airtac SAI40 Standard Air Cylinder SAI40BX475 the Right Cylinder?
If your application requires less push force, stepping down to the 32 mm bore yields 402 N at 0.5 MPa, whereas moving up to the 50 mm bore provides 982 N for heavier loads. Because this 475 mm stroke creates a long unsupported rod extension, side loads can cause rod-bearing bending and premature wear; using an external guide rail or a fully guided cylinder is strongly recommended to maintain alignment.
As a dimensionally interchangeable ISO 15552 cylinder, this model serves as a direct replacement matching a 40 mm bore, 475 mm stroke, PT G1/4 port, and standard FA/FB flange or LB foot mounting accessories. Note that this standard cylinder will drift if air pressure is lost; for position holding without live pressure, consider the SAIL locking variant or an external pilot-operated check valve.
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 SAI40BX475 FAQ
The SAI40X475 provides a push force of 628 N and a pull force of 528 N at 0.5 MPa. At 0.7 MPa, the push force increases to 879 N.
Yes, the SAI40X475 is dimensionally interchangeable per ISO 15552 standards. You can drop it in to replace other ISO 15552 profile cylinders with a 40 mm bore, matching the G1/4 port and standard mounting accessories.
