About the Airtac SAI100 Standard Air Cylinder SAI100AX450
The AirTAC SAI100X450 is a double-acting ISO 15552 profile cylinder engineered to deliver a robust 3927 N of push force at 0.5 MPa and a maximum theoretical output of 801 kgf at 1.0 MPa. The 450 mm stroke provides ample extension for mid-distance material handling and automated machinery actuation.
Built with an SUS420J2 stainless steel piston rod (material code A), this model offers superior corrosion and wear resistance in demanding environments. It features a PT tapered port thread and excludes a magnet, meaning it is optimized for pure mechanical actuation rather than direct sensor mounting.

Where the Airtac SAI100 Standard Air Cylinder SAI100AX450 Is Used
Heavy-Duty Pressing
Provides the 3927 N push force at 0.5 MPa required for seating bearings, stamping light components, and assembling heavy mechanical sub-assemblies.
Pallet Diversion
The 450 mm stroke easily extends across wide conveyor lanes to divert heavy pallets or route bulky packages in high-throughput logistics centers.
Automated Welding
The SUS420J2 stainless rod withstands weld spatter and shop debris, making it ideal for positioning heavy jigs and clamps in robotic welding cells.
Is the Airtac SAI100 Standard Air Cylinder SAI100AX450 the Right Cylinder?
With a 100 mm bore generating 3927 N at 0.5 MPa, stepping down to an 80 mm bore drops the output to 2513 N, while moving up to a 125 mm bore increases it to 6136 N. Because this 450 mm stroke creates a long unsupported rod extension, applying side loads directly to the piston rod can cause rod-bearing bending and premature wear; utilize an external guide rail or a fully guided cylinder to manage off-center loads.
As a true ISO 15552 profile cylinder, this unit is dimensionally interchangeable with other ISO 15552 cylinders, making it a drop-in replacement for existing 100 mm bore setups. To match this specific configuration, specify a 100 mm bore, 450 mm stroke, PT port thread, SUS420J2 rod material, and no magnet (-S). Note that the adjustable air cushions only decelerate the piston at stroke end and do not hold a load; if pressure is lost, the cylinder drifts. For position holding, consider the SAIL (air-released lock) or BSAI (clamp-lock) 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 SAI100 Standard Air Cylinder SAI100AX450 FAQ
At a 0.5 MPa operating pressure, the SAI100X450 generates 3927 N of push force and 3681 N of pull force. At the maximum 1.0 MPa pressure, it achieves a theoretical output of 801 kgf.
Yes, the SAI100X450 is a genuine ISO 15552 profile cylinder. Its standardized mounting dimensions make it a drop-in replacement for other ISO 15552 cylinders, provided you match the 100 mm bore, 450 mm stroke, and PT port.
