About the Airtac SAI80 Standard Air Cylinder SAI80BX145
The AirTAC SAI80X145 is a double-acting ISO 15552 profile cylinder engineered to deliver 2513N of push force at 0.5MPa. Its 145mm stroke is well-suited for medium-travel automation tasks requiring substantial thrust. The extruded aluminum barrel design omits tie rods, providing a clean exterior that simplifies mounting and sensor placement.
This specific configuration features a SUS304 stainless steel piston rod (option B) for superior corrosion resistance in harsh or washdown environments. It utilizes PT tapered port threads and lacks a magnet. If your application requires position holding without live air pressure, consider the SAIL locking variant or an external rod lock.

Where the Airtac SAI80 Standard Air Cylinder SAI80BX145 Is Used
Automated Pressing
Provides reliable 2513N push force at 0.5MPa for assembling components and pressing bearings in automated machinery.
Material Diverting
Actuates heavy-duty diverter arms and sorting gates on conveyor lines where robust thrust is required.
Packaging Equipment
Drives sealing jaws and forming mechanisms in industrial packaging machines requiring a 145mm travel distance.
Is the Airtac SAI80 Standard Air Cylinder SAI80BX145 the Right Cylinder?
Selecting this 80mm bore provides 2513N push and 2268N pull force at 0.5MPa. If your application requires less force, stepping down to the 63mm bore yields 1559N push force, while moving up to the 100mm bore offers 3927N push force. The 145mm stroke is a non-standard intermediate length, falling between the standard 125mm and 150mm options, which may require made-to-order processing.
Because the stroke is under 300mm, side-load stress on the rod bearing is minimal compared to longer strokes. However, for heavy radial loads, always use external guides. The PT ports match the G3/8 standard for this bore size. Mounting accessories include LB foot brackets, FA/FB flanges, and CA/CB clevises. This cylinder is dimensionally interchangeable per ISO 15552, serving as a direct replacement for other ISO 15552 profile cylinders.
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.
