About the Airtac SAI100 Standard Air Cylinder SAI100BX280S
The AirTAC SAI100X280-S is a double-acting ISO 15552 profile cylinder engineered for rigorous automation environments. Delivering a robust 3927 N push force at 0.5 MPa, this 100 mm bore unit handles heavy material manipulation with precision. The 280 mm stroke provides ample travel for indexing, clamping, and lifting tasks. As a genuine AirTAC component, it guarantees reliable performance.
This specific configuration features a SUS304 stainless steel piston rod (material code B), ensuring superior corrosion resistance for washdown or chemically exposed settings. Equipped with a magnet (-S), it seamlessly integrates with CMSE and DMSE sensor switches via the dual-sided extruded barrel grooves. PT tapered port threads guarantee a leak-free pneumatic connection.

Where the Airtac SAI100 Standard Air Cylinder SAI100BX280S Is Used
Automotive Stamping
Provides the high push force required to form and seat heavy metal panels in automotive assembly lines.
Heavy Duty Clamping
Secures large machined castings firmly in place during high-torque CNC milling operations.
Pallet Indexing
Lifts and positions loaded pallets at transfer stations, utilizing the 280mm stroke for smooth transitions.
Is the Airtac SAI100 Standard Air Cylinder SAI100BX280S the Right Cylinder?
Selecting this 100 mm bore over the smaller 80 mm variant upgrades your thrust from 2513 N to 3927 N at 0.5 MPa, while stepping up to the 125 mm bore yields 6136 N if your application demands extreme power. Because the 280 mm stroke exceeds 300 mm in total rod extension, it is critical to manage side loads. Avoid rod-bearing bending by utilizing an external guide rail or selecting a guided cylinder to support heavy off-center masses.
For ISO 15552 interchangeability, this model matches a 100 mm bore, 280 mm stroke, G1/2 port, and PT thread configuration. It accommodates standard mounting accessories like FA flanges or TC trunnions. Note that a standard SAI does not hold its position upon air loss; for fail-safe load holding, consider the SAIL (air-released lock) or BSAI (clamp-lock) variant.
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.
