About the Airtac SAI32 Standard Cylinder SAI32X280
The AirTAC SAI32X280 is a double-acting ISO 15552 profile cylinder engineered to deliver 402 N of push force and 345 N of pull force at 0.5 MPa. Its 280 mm stroke is well-suited for intermediate reach tasks in automated machinery. The extruded aluminum barrel design eliminates tie-rods, providing a clean exterior that simplifies sensor mounting along the full length of the body.
Beyond the standard specifications, this configuration features a carbon steel piston rod for robust mechanical strength in industrial environments. It utilizes a PT tapered port thread for a reliable, tight pneumatic connection. Because no magnet is specified, it operates without electronic position sensing, relying purely on mechanical end-of-stroke limits.

Where the Airtac SAI32 Standard Cylinder SAI32X280 Is Used
Package Diverting
Ideal for actuating diverters on packaging lines where 402 N of push force reliably redirects medium-weight cardboard cartons.
Small Press Ejection
Provides the necessary 280 mm reach to eject small molded parts from a press bed into a collection chute.
Pallet Stopper Arms
Deploys a stopping arm at conveyor junctions to halt pallets, utilizing its double-acting action for rapid retraction.
Is the Airtac SAI32 Standard Cylinder SAI32X280 the Right Cylinder?
When selecting this model, compare its 402 N output at 0.5 MPa against the neighboring 40 mm bore, which provides 628 N of push force. If your application requires less force and a smaller footprint, the 32 mm bore is highly efficient. For this 280 mm stroke, which exceeds 300 mm when considering the extended rod length, it is critical to manage side loads. An unsupported rod of this length can bend under lateral stress, so utilizing an external guide rail or a guided cylinder carriage is recommended to prevent premature seal wear.
This cylinder serves as a dimensionally interchangeable direct replacement per the ISO 15552 mounting interface. To match this specific unit, ensure your setup requires a 32 mm bore, 280 mm stroke, PT port thread, and standard mounting accessories like an FA flange or LB foot bracket. Note that the standard SAI does not hold its position if air pressure is lost; if your application requires static load holding without live pressure, consider the SAIL (air-released lock) variant or an external pilot-operated check valve.
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 SAI32 Standard Cylinder SAI32X280 FAQ
