About the Airtac SAI80 Standard Air Cylinder SAI80BX5
The AirTAC SAI80X5 is a double-acting ISO 15552 profile cylinder engineered for very short stroke applications, delivering a robust push force of 2513 N at 0.5 MPa. This non-standard 5 mm stroke is made to order, providing precise linear movement where standard longer strokes cannot fit. The extruded aluminum barrel design omits tie rods, ensuring a clean exterior while maintaining strict dimensional interchangeability per ISO 15552.
This specific configuration features a SUS304 stainless steel piston rod (option B), offering superior corrosion resistance for harsh or washdown environments. It utilizes PT tapered port threading and operates without a magnet. For applications requiring end-position holding without live air pressure, the standard SAI does not lock; consider the SAIL variant or an external rod lock.

Where the Airtac SAI80 Standard Air Cylinder SAI80BX5 Is Used
High-Force Clamping
Delivers 2513 N of push force at 0.5 MPa for securing heavy stamping or welding fixtures in a minimal footprint.
Short-Stroke Ejection
Ideal for quickly ejecting dense parts from press beds or molds where only a few millimeters of travel are required.
Corrosion-Resistant Actuation
The SUS304 stainless steel rod ensures reliable operation in food processing or chemical packaging lines with frequent washdowns.
Is the Airtac SAI80 Standard Air Cylinder SAI80BX5 the Right Cylinder?
Selecting this 80 mm bore model is ideal when you need high force in a severely confined space, as the 5 mm stroke provides rapid, high-impact clamping. If you need slightly less force, stepping down to a 63 mm bore yields 1559 N at 0.5 MPa, whereas stepping up to a 100 mm bore provides 3927 N. Because the stroke is extremely short, side-load bending is negligible, but ensure the mounting accessories (like FA flange or LB foot) are rigidly aligned.
This genuine AirTAC unit functions as a direct replacement for other ISO 15552 profile cylinders, matching the 80 mm bore, 5 mm stroke, PT G3/8 port, and standard mounting dimensions exactly. Note that air cushions are present at both ends to decelerate the piston, but they do not act as a brake or load-holding device.
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 SAI80BX5 FAQ
At an operating pressure of 0.5 MPa, the SAI80X5 generates a push force of 2513 N and a pull force of 2268 N. At 0.7 MPa, the push force increases to 3518 N.
Yes, as a genuine ISO 15552 profile cylinder, it is dimensionally interchangeable with other ISO 15552 cylinders of the same 80 mm bore and 5 mm stroke, using a PT G3/8 port.
