About the Airtac SAI100 Standard Air Cylinder SAI100BX280
The AirTAC SAI100X280 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty linear motion. Delivering a robust push force of 3927 N at 0.5 MPa and a maximum theoretical output of 801 kgf, this 100mm bore actuator handles substantial payloads with ease. The 280mm stroke provides ample travel for pressing, lifting, and clamping operations.
This genuine AirTAC unit is configured with a corrosion-resistant SUS304 stainless steel piston rod (B code) and PT tapered port threads. The extruded aluminum barrel incorporates dual sensor grooves, allowing for direct mounting of CMSE or DMSE series switches if position feedback is later required.

Where the Airtac SAI100 Standard Air Cylinder SAI100BX280 Is Used
Heavy-Duty Pressing
Ideal for assembly lines requiring high force, using the 3927 N push capability at 0.5 MPa to seat bearings or form components securely.
Pallet Lifting
The 280mm stroke provides the necessary travel to elevate heavy industrial pallets or actuators in automated material handling systems.
Rigid Clamping
Holds large metal or composite workpieces firmly in place during CNC machining or welding operations using the 100mm bore power.
Is the Airtac SAI100 Standard Air Cylinder SAI100BX280 the Right Cylinder?
Selecting this 100mm bore over the neighboring 80mm size increases your thrust from 2513 N to 3927 N at 0.5 MPa, providing the extra power needed for heavier fixtures. Conversely, if your application only requires 2513 N, dropping to the 80mm bore saves space and air consumption.
Because the 280mm stroke exceeds the 300mm threshold, it is critical to manage side loads. An unsupported extended rod can bend under lateral forces; utilize an external guide rail or a guided cylinder to prevent premature wear on the rod bearing. Note that this standard cylinder does not hold its load if air pressure is lost—integrate a SAIL variant with an air-released lock or an external rod lock for fail-safe vertical positioning.
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.
