About the Airtac SAI80 Standard Air Cylinder SAI80BX250
The AirTAC SAI80X250 is a double-acting ISO 15552 profile cylinder featuring an 80mm bore and a 250mm stroke. It provides a robust push force of 2513 N and a pull force of 2268 N at 0.5 MPa, making it well-suited for heavy-duty positioning tasks. The extruded aluminum barrel design integrates sensor grooves on both sides for straightforward detection installation.
This specific configuration is built with a SUS304 stainless steel rod (option B) for superior corrosion resistance in harsh environments. It utilizes PT tapered port threads and does not include a standard magnet. If your workflow requires intermediate stopping or load holding without continuous air pressure, consider the SAIL variant or an external rod lock.

Where the Airtac SAI80 Standard Air Cylinder SAI80BX250 Is Used
Heavy-Duty Pressing
Ideal for applying 2513 N of push force at 0.5 MPa for stamping, riveting, and assembling dense metal components.
Pallet Diverting
The 250mm stroke provides the exact reach needed to redirect heavy pallets on automated packaging and distribution lines.
Clamping Fixtures
Generates reliable holding power for large welded frames, ensuring parts stay secured during machining processes.
Is the Airtac SAI80 Standard Air Cylinder SAI80BX250 the Right Cylinder?
Selecting this 80mm bore makes sense when a 63mm bore (offering 1559 N push at 0.5 MPa) lacks the necessary thrust for heavier fixtures. If you need even higher force, stepping up to a 100mm bore yields 3927 N. The 250mm stroke provides ample travel for material handling, but strokes of 300mm or greater require careful attention to side-load management to prevent rod-bearing bending; utilizing an external guide mechanism or a guided cylinder is recommended for long unsupported rods.
As a true ISO 15552 profile cylinder, this unit is dimensionally interchangeable with other ISO 15552 cylinders, ensuring a seamless direct replacement. When integrating, match your 80mm bore, 250mm stroke, PT G3/8 port, and desired mounting accessory (such as LB foot or TC trunnion). Note that a magnet (-S) is required if you intend to use CMSE or DMSE sensor switches.
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.
