About the Airtac SAI80 Standard Air Cylinder SAI80BX20S
The AirTAC SAI80X20-S is a double-acting ISO 15552 profile cylinder engineered for short-stroke, high-force tasks. It provides a push force of 2513 N at 0.5 MPa, utilizing a 25 mm piston rod and G3/8 PT ports. The 20 mm stroke is optimal for compact clamping or ejection operations where space is restricted.
This configuration includes a SUS304 stainless steel rod (material code B) for superior corrosion resistance. The integrated magnet (-S) enables seamless position detection using CMSE or DMSE switches seated in the dual sensor grooves along the extruded aluminum barrel.

Where the Airtac SAI80 Standard Air Cylinder SAI80BX20S Is Used
Short-Stroke Clamping
Generates 2513 N of clamping force at 0.5 MPa to secure heavy metal workpieces for machining operations.
Product Ejection
Uses its brief 20 mm stroke to rapidly push finished parts off a conveyor belt without extending into walkways.
Press Operations
Provides reliable downward thrust for light-duty pressing and riveting tasks within compact automated cells.
Is the Airtac SAI80 Standard Air Cylinder SAI80BX20S the Right Cylinder?
Select this 80 mm bore when an application requires significantly more thrust than a 63 mm cylinder (which yields 1559 N at 0.5 MPa) but lacks the physical depth for a longer stroke. For operations needing precise position holding without constant air pressure, a standard SAI will drift; consider the SAIL variant with an air-released lock or an external pilot check valve. As a dimensionally interchangeable ISO 15552 component, it serves as a direct replacement matching the 80 mm bore, 20 mm 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 SAI80BX20S FAQ
At an operating pressure of 0.5 MPa, this 80 mm bore cylinder generates a push force of 2513 N and a pull force of 2268 N. It can reach up to 4523 N at 0.9 MPa.
Yes, the SAI80X20-S is dimensionally interchangeable per ISO 15552 standards. It shares standard mounting dimensions, G3/8 PT ports, and a 25 mm rod thread, allowing it to serve as a direct replacement for equivalent profile cylinders.
