About the Airtac SAI80 Standard Air Cylinder SAI80BX450
The AirTAC SAI80X450 is a double-acting ISO 15552 profile cylinder offering a robust 2513N push force at 0.5MPa. Its 450mm stroke handles extended travel requirements for moving heavier loads in automated lines. The extruded aluminum barrel eliminates tie rods, providing a clean exterior while maintaining strict dimensional interchangeability with other ISO 15552 cylinders.
This specific configuration features a SUS304 stainless steel piston rod (material code B) for superior corrosion resistance in humid or washdown environments. It uses PT tapered port threads and lacks a magnet, meaning it is optimized for purely mechanical actuation without sensor detection. Standard adjustable air cushions at both ends absorb kinetic energy at 30-800mm/s operating speeds.

Where the Airtac SAI80 Standard Air Cylinder SAI80BX450 Is Used
Material Handling
Pushes heavy pallets or totes along extended conveyor sections using the full 450mm stroke and 2513N force.
Automated Assembly
Actuates large press fixtures or clamping mechanisms where the SUS304 rod resists coolant exposure.
Logistics Sorting
Diverts heavy packages at high speeds, relying on adjustable cushions to decelerate the 80mm piston smoothly.
Is the Airtac SAI80 Standard Air Cylinder SAI80BX450 the Right Cylinder?
When selecting this model, verify that 2513N of push force at 0.5MPa (or 3518N at 0.7MPa) is sufficient for your load. If your application requires less force, stepping down to a 63mm bore yields 1559N at 0.5MPa, while moving up to a 100mm bore provides 3927N. Because this 450mm stroke creates a long unsupported rod extension, side loads can cause severe bending stress on the rod bearing. For applications with offset loads, utilize an external guide rail or switch to a guided cylinder to prevent premature seal wear.
As a dimensionally interchangeable ISO 15552 profile cylinder, this 80mm bore unit with a 450mm stroke and PT G3/8 ports serves as a direct replacement for standard mounting footprints. It pairs with FA/FB flanges or LB foot mounts. Note that this standard cylinder does not hold its position if air pressure drops; use the SAIL (air-released lock) variant if fail-safe load holding is required.
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 SAI80 Standard Air Cylinder SAI80BX450 FAQ
