About the Airtac SAI100 Standard Air Cylinder SAI100AX280S
The AirTAC SAI100X280-S is a double-acting ISO 15552 profile cylinder featuring a 100mm bore and 280mm stroke. It generates a robust push force of 5497 N at 0.7 MPa, making it well-suited for heavy-duty positioning and high-load automation tasks.
This configuration includes a magnetic piston (-S) for direct mounting of CMSE or DMSE sensor switches along the dual grooves machined into the extruded aluminum barrel. The piston rod is constructed from SUS420J2 stainless steel for enhanced corrosion resistance, and the pneumatic supply connects via a PT tapered G1/2 port.

Where the Airtac SAI100 Standard Air Cylinder SAI100AX280S Is Used
Heavy-Duty Pressing
Ideal for applying consistent, high-force pressure in metal forming, riveting, and stamping operations up to 7068 N at 0.9 MPa.
Pallet Diversion
Provides the robust actuation needed to deflect heavy pallets or redirect large product flows on high-throughput material handling lines.
Automated Clamping
Secures large workpieces or heavy machinery frames during machining, welding, or assembly processes where rigid holding is critical.
Is the Airtac SAI100 Standard Air Cylinder SAI100AX280S the Right Cylinder?
When selecting this 100mm bore actuator, verify your force requirements against its 3927 N push force at 0.5 MPa. If your application demands less energy, stepping down to an 80mm bore yields 2513 N at the same pressure, while moving up to a 125mm bore provides 6136 N for heavier loads.
At a 280mm stroke, the extended rod is susceptible to bending under side loads. To prevent premature rod-bearing wear, implement an external guide rail or choose a guided cylinder to handle lateral forces. Because this is a standard double-acting cylinder, it will not maintain its position if air pressure drops; for fail-safe load holding, consider the SAIL or BSAI variants. This unit serves as a dimensional drop-in replacement for any ISO 15552 cylinder with a 100mm bore, 280mm stroke, and G1/2 port.

- ✓ 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.
