About the Airtac SAI80 Standard Air Cylinder SAI80BX45S
The AirTAC SAI80X45-S is a double-acting ISO 15552 profile cylinder engineered for robust actuation, delivering a push force of 2513 N and a pull force of 2268 N at 0.5 MPa. Its short 45 mm stroke makes it exceptionally well-suited for high-impact clamping, holding, and pressing operations where compact extension is required.
This specific configuration features a SUS304 stainless steel rod (code B) for superior corrosion resistance and includes a built-in magnet (-S) for seamless integration with CMSE or DMSE sensor switches along the dual grooves of the extruded aluminum barrel. Fluid is filtered air, operating reliably between -20 and +70 C.

Where the Airtac SAI80 Standard Air Cylinder SAI80BX45S Is Used
Heavy-Duty Clamping
Ideal for securing thick metal workpieces during machining, utilizing its 2513 N push force to prevent vibration and shifting under aggressive tooling.
Short-Stroke Pressing
Performs localized pressing and riveting tasks where a brief, high-force 45 mm extension is required to seat bearings or deform components.
Pallet Halting
Acts as a robust stopper mechanism on heavy-load conveyor lines, deploying the rod quickly to arrest moving pallets without overshoot.
Is the Airtac SAI80 Standard Air Cylinder SAI80BX45S the Right Cylinder?
Select this 80 mm bore when an application demands more power than a 63 mm cylinder (which provides 1559 N push at 0.5 MPa) but lacks the physical space for a 100 mm unit. For this 45 mm stroke, side-load stress on the rod bearing is minimal, though external guides should still be used if absorbing heavy lateral moments.
Because it is a true ISO 15552 profile cylinder, it serves as a direct replacement for any standard ISO 15552 unit with an 80 mm bore, 45 mm stroke, and G3/8 or PT ports. If the machinery requires the piston to maintain its position during a complete loss of air pressure, a standard SAI will drift; utilize the SAIL variant with an air-released lock or an external pilot-operated check valve for fail-safe holding.
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 SAI80BX45S FAQ
At a standard operating pressure of 0.5 MPa, this cylinder generates 2513 N of push force and 2268 N of pull force. If pressure is increased to 0.7 MPa, the push force rises to 3518 N.
Yes. The SAI80X45-S is dimensionally interchangeable per ISO 15552. You can swap it directly into existing mounts designed for standard ISO 15552 80 mm bore cylinders with a 45 mm stroke and G3/8 ports.
