About the Airtac SAI80 Standard Air Cylinder SAI80BX55
The AirTAC SAI80X55 is a double-acting ISO 15552 profile cylinder featuring an 80mm bore and a 55mm stroke. It delivers a robust push force of 2513N and a pull force of 2268N at 0.5 MPa, making it well-suited for medium-to-heavy actuation tasks requiring a short, decisive movement.
Built with a durable extruded aluminum barrel, this specific configuration includes a SUS304 stainless steel piston rod (material code B) for superior corrosion resistance in washdown or humid settings. It uses PT tapered port threads and operates reliably at speeds between 30 and 800 mm/s.

Where the Airtac SAI80 Standard Air Cylinder SAI80BX55 Is Used
Automated Pressing
Provides the necessary 2513N push force at 0.5 MPa for securely stamping or seating components within automated machinery.
Package Diversion
Executes rapid 55mm strokes to actuate diverter arms and sort packages along high-speed material handling lines.
Clamp Actuation
Drives heavy-duty clamping mechanisms to hold workpieces firmly in position during secondary machining operations.
Is the Airtac SAI80 Standard Air Cylinder SAI80BX55 the Right Cylinder?
If your application requires less force, stepping down to the 63mm bore variant yields 1559N of push force at 0.5 MPa, whereas moving up to the 100mm bore provides 3927N. For this 55mm stroke, side-load stress on the rod bearing is minimal, but always ensure axial alignment to prevent premature seal wear. Because this is a standard double-acting cylinder, it will not hold a load if air pressure is lost; for dead-end holding, consider the SAIL locking variant or an external pilot-operated check valve. This ISO 15552 form serves as a dimensionally interchangeable direct replacement for other standard profile cylinders, matching the 80mm bore, 55mm stroke, G3/8 port, and standard mounting accessories like FA flanges or TC trunnions.
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 SAI80BX55 FAQ
At an operating pressure of 0.5 MPa, the SAI80X55 generates 2513N of push force and 2268N of pull force. At 0.7 MPa, the push force increases to 3518N.
Yes, the SAI80X55 is a true ISO 15552 profile cylinder. It is dimensionally interchangeable with other ISO 15552 standard cylinders of the same bore and stroke, utilizing a G3/8 port and standard mounting interfaces.
