About the Airtac SAI80 Standard Air Cylinder SAI80BX30
The AirTAC SAI80X30 is a double-acting ISO 15552 profile cylinder engineered for high-force automation tasks. It delivers a robust push force of 2513 N at 0.5 MPa, making it ideal for short-stroke clamping and heavy-duty ejection. The 30 mm stroke provides rapid, precise actuation in compact spaces.
This specific configuration features a SUS304 stainless steel piston rod (material code B) for superior corrosion resistance in wet or washdown environments. It utilizes PT tapered port threads and lacks a standard magnet, meaning position sensing via CMSE or DMSE switches requires adding the -S option at order. The extruded aluminum barrel design ensures rigid, tie-rod-less construction fully interchangeable with other ISO 15552 standard cylinders.

Where the Airtac SAI80 Standard Air Cylinder SAI80BX30 Is Used
Heavy-Duty Stamping
Provides the high impact force needed for short-stroke stamping and marking operations in metal fabrication lines.
Pallet Clamping
Secures heavy pallets or workpieces firmly in place during automated packaging and machining processes.
Product Diversion
Acts as a robust diverter arm actuator, swiftly pushing heavy goods off a main conveyor belt onto a secondary line.
Is the Airtac SAI80 Standard Air Cylinder SAI80BX30 the Right Cylinder?
Select this 80 mm bore model when an application demands significantly more thrust than a 63 mm cylinder can provide, yet lacks the physical envelope for a 100 mm unit. If your force requirements are lower, stepping down to a 63 mm bore yields 1559 N at 0.5 MPa and saves valuable space. Because the 30 mm stroke is very short, side-load stress on the rod bearing is minimal compared to longer strokes.
As a standard double-acting pneumatic actuator, this cylinder relies on continuous air pressure to maintain its position. If air is lost or exhausted, the piston will drift. For applications requiring true load holding without live pressure, consider the SAIL variant with an air-released lock or the BSAI bidirectional clamp-lock series. This SAI80X30 serves as a direct dimensional direct replacement for any ISO 15552 cylinder with an 80 mm bore, 30 mm stroke, and G3/8 ports.
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 SAI80BX30 FAQ
At a standard 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. If pressure is increased to 0.7 MPa, the push force reaches 3518 N.
Yes. The SAI80X30 is built to the ISO 15552 standard, meaning its mounting dimensions, 80 mm bore, 30 mm stroke, and G3/8 port locations are fully interchangeable with other ISO 15552 profile cylinders.
