About the Airtac SAI80 Standard Air Cylinder SAI80BX140
The AirTAC SAI80X140 is a double-acting profile cylinder featuring a 80mm bore and 140mm stroke, fully conforming to the ISO 15552 mounting interface. It generates a robust push force of 2513 N and a pull force of 2268 N at 0.5 MPa, making it well-suited for medium-to-heavy actuation tasks.
This specific configuration is built with a SUS304 stainless steel piston rod (material code B) for superior corrosion resistance in washdown or chemically active settings. It utilizes PT tapered thread ports, and because it lacks the -S magnet suffix, it does not have integrated sensor tracks for reed switches.

Where the Airtac SAI80 Standard Air Cylinder SAI80BX140 Is Used
Metal Stamping Press
Provides the necessary 2513 N push force at 0.5 MPa to hold heavy sheet metal blanks securely in place during stamping operations.
Package Diverting Arm
Actuates a heavy-duty diverter mechanism on high-speed packaging lines, utilizing its 140mm stroke to route large cartons efficiently.
Woodworking Clamp
Secures thick wooden workpieces against routing spindles, leveraging the stainless steel rod to withstand dusty and occasionally humid shop environments.
Is the Airtac SAI80 Standard Air Cylinder SAI80BX140 the Right Cylinder?
Choose this 80mm bore when a 63mm cylinder lacks thrust; the SAI63 provides 1559 N push at 0.5 MPa, whereas this SAI80 steps up to 2513 N. If your application requires less force, stepping down prevents unnecessary air consumption. For this 140mm stroke, side-load bending is minimal, but always ensure rigid mounting using FA or FB flanges to maintain alignment.
Because this is a standard double-acting cylinder, it relies on live air pressure to hold position. If your machinery experiences sudden pressure loss, the piston will drift. For fail-safe load holding, integrate an external pilot-operated check valve or select the AirTAC BSAI bidirectional 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.
Airtac SAI80 Standard Air Cylinder SAI80BX140 FAQ
At a standard operating pressure of 0.5 MPa, the SAI80X140 delivers a push (extend) force of 2513 N and a pull (retract) force of 2268 N. At 0.7 MPa, the push force increases to 3518 N.
Yes. The SAI80X140 is a genuine AirTAC profile cylinder built to the ISO 15552 standard, making its mounting dimensions fully interchangeable with other ISO 15552 cylinders of the same bore size, such as those from SMC or Festo.
