About the Airtac SAI80 Standard Air Cylinder SAI80BX425
The AirTAC SAI80X425 is a double-acting ISO 15552 profile cylinder engineered to deliver 2513 N of push force at 0.5 MPa. With an 80 mm bore and 425 mm stroke, it is tailored for heavy-duty positioning tasks requiring substantial travel. The extruded aluminum barrel design omits tie rods, providing a clean exterior that resists contamination.
This specific configuration incorporates a SUS304 stainless steel piston rod for superior corrosion resistance in humid or washdown settings. It utilizes PT tapered port threads, and because it lacks a magnet, it is optimized for pure actuation without electronic position sensing.

Where the Airtac SAI80 Standard Air Cylinder SAI80BX425 Is Used
Material Lift
Raises heavy pallets or chassis components over a 425 mm travel distance, utilizing the 2513 N push force to elevate loads reliably.
Product Diversion
Pushes heavy packages across conveyor belts, where the 80 mm bore provides the necessary thrust to redirect bulky items without stalling.
Clamping Fixtures
Secures large metal castings during CNC machining, using the extended stroke to accommodate varying part widths.
Is the Airtac SAI80 Standard Air Cylinder SAI80BX425 the Right Cylinder?
Selecting this 80 mm bore makes sense when 50 mm (982 N) lacks the necessary power but stepping up to 100 mm (3927 N) is oversized. The 425 mm stroke extends a long unsupported rod, making the piston highly susceptible to bending under side loads. To prevent premature rod-bearing wear, implement an external linear guide or switch to a guided cylinder.
This actuator serves as a dimensionally interchangeable direct replacement for any ISO 15552 cylinder. If the machinery must maintain vertical loads during a pressure loss, note that the standard adjustable air cushions only decelerate the piston and do not act as a brake; deploy an external rod lock or the AirTAC BSAI clamp-lock variant instead.
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.
