About the Airtac SAI100 Standard Air Cylinder SAI100BX475S
The AirTAC SAI100X475-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. It delivers a robust push force of 3927 N at 0.5 MPa, making it well-suited for high-inertia loads over its 475 mm stroke. The extruded aluminum barrel design eliminates tie rods, providing a clean exterior and high structural rigidity.
This specific configuration includes a SUS304 stainless steel rod for superior corrosion resistance in harsh environments. It features a built-in magnet (-S) enabling seamless integration with CMSE or DMSE reed switches via the dual sensor grooves on the barrel. Fluid connections use PT tapered threads, and the adjustable air cushions at both ends ensure smooth end-of-stroke deceleration.

Where the Airtac SAI100 Standard Air Cylinder SAI100BX475S Is Used
Heavy-Duty Pressing
Ideal for applying 3927 N of pressing or clamping force on thick metal sheets and heavy structural components during fabrication.
Large Pallet Diversion
The 475 mm stroke provides the extended reach needed to push heavy pallets or large workpieces smoothly off high-capacity conveyor lines.
Automated Assembly Lifts
Excels in lifting heavy sub-assemblies between manufacturing tiers, utilizing its SUS304 rod for reliable performance in mildly corrosive factory settings.
Is the Airtac SAI100 Standard Air Cylinder SAI100BX475S the Right Cylinder?
Selecting this 100 mm bore over the smaller 80 mm variant is ideal when you need to step up from 2513 N to 3927 N of push force at 0.5 MPa to handle heavier workpieces. Conversely, if your load is lighter, stepping down to an 80 mm bore saves air consumption. Because this 475 mm stroke exceeds 300 mm, the unsupported rod is susceptible to bending under side loads; for optimal longevity, use an external guide rail or a guided cylinder to prevent premature rod-bearing wear.
This model is dimensionally interchangeable per ISO 15552, serving as a drop-in replacement for other ISO 15552 profile cylinders. To match this unit, specify a 100 mm bore, 475 mm stroke, PT G1/2 port, FA/FB flange or TC trunnion mounting, and a -S magnet. Remember that standard air cushions only decelerate the piston near stroke end; if the application must hold a load vertically without live air pressure, integrate the SAIL (lock) or BSAI (clamp-lock) 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 SAI100 Standard Air Cylinder SAI100BX475S FAQ
