About the Airtac SAI80 Standard Air Cylinder SAI80BX25
The AirTAC SAI80X25 is a double-acting ISO 15552 profile cylinder engineered for high-force, short-stroke tasks. It provides a push force of 2513 N at 0.5 MPa and reaches 3518 N at 0.7 MPa. The 25 mm stroke is optimal for compact clamping or heavy lifting where space is strictly limited.
This specific configuration features a SUS304 stainless steel rod for superior corrosion resistance and utilizes PT tapered port threads. As a genuine ISO 15552 extruded-aluminum profile cylinder, it offers direct dimensional interchangeability for standardized mounting setups without relying on tie-rod construction.

Where the Airtac SAI80 Standard Air Cylinder SAI80BX25 Is Used
Heavy-Duty Clamping
Generates 2513 N of clamping force at 0.5 MPa to secure heavy metal workpieces during machining or welding operations.
Short-Stroke Pressing
Ideal for compact pressing and stamping stations requiring high impact force within a very tight 25 mm travel distance.
Product Ejection
Delivers rapid, high-force ejection of finished parts from conveyor lines or press beds in automated manufacturing.
Is the Airtac SAI80 Standard Air Cylinder SAI80BX25 the Right Cylinder?
Select this 80 mm bore when a 63 mm bore (delivering 1559 N at 0.5 MPa) lacks the necessary thrust, but a 100 mm bore (3927 N) would be physically oversized. The 25 mm stroke minimizes rod-bearing bending stress, making it highly robust against slight side loads.
Because this is a standard double-acting cylinder, it cannot hold a load if air pressure drops; use a SAIL variant or external rod lock for fail-safe position holding. Mounting accessories include FA/FB flanges and TC trunnions. The PT port and lack of a magnet (-S) match this exact specification.
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.
