About the Airtac SAI50 Standard Cylinder SAI50BX280
The AirTAC SAI50X280 is a double-acting ISO 15552 profile cylinder offering a 982 N push force at 0.5 MPa. Its 280 mm stroke provides the extended travel needed for mid-range material handling and automated positioning tasks.
This specific configuration utilizes a SUS304 stainless steel piston rod for superior corrosion resistance. It features PT tapered port threads and, because no magnet is specified, it ships without sensor activation hardware.

Where the Airtac SAI50 Standard Cylinder SAI50BX280 Is Used
Package Diverting
Extends 280 mm to push cartons off a main conveyor belt onto secondary packaging lines.
Clamp Actuation
Drives mid-sized clamping arms to secure aluminum extrusions during CNC machining operations.
Pallet Stops
Acts as a pneumatic stop gate to halt pallets at specific workstation checkpoints.
Is the Airtac SAI50 Standard Cylinder SAI50BX280 the Right Cylinder?
Choose this 50 mm bore when a 40 mm bore (628 N at 0.5 MPa) lacks the necessary push strength, but a larger 63 mm cylinder would be physically oversized. Because the 280 mm stroke creates an extended unsupported rod length, it is highly susceptible to bending under side loads. Implement an external guide rail or select a guided cylinder to prevent premature rod-bearing wear.
As a standard double-acting actuator, this cylinder will drift if air pressure is lost or the valve centers; it cannot hold a load mid-stroke. For dead-load holding, specify the SAIL variant with an air-released lock or integrate an external pilot-operated check valve. This model is dimensionally interchangeable per ISO 15552, accepting standard FA/FB flanges or LB foot mounts.
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.
Airtac SAI50 Standard Cylinder SAI50BX280 FAQ
