About the Airtac SAI32 Standard Cylinder SAI32BX325
The AirTAC SAI32X325 is a double-acting ISO 15552 profile cylinder offering 402 N of push force at 0.5 MPa. Its 325 mm stroke makes it highly suitable for medium-travel routing and transfer tasks. The extruded aluminum barrel design omits tie rods, providing a clean exterior that drops right into standardized ISO 15552 mounting footprints.
Built for demanding environments, this specific configuration utilizes a SUS304 stainless steel piston rod for superior corrosion resistance. It features PT tapered port threads and lacks a standard magnet. If your application requires end-position sensing, you would need the -S magnet option to utilize CMSE or DMSE switches in the dual sensor grooves.

Where the Airtac SAI32 Standard Cylinder SAI32BX325 Is Used
Package Routing
Diverts small to medium parcels along a 325 mm transfer path with precise 402 N push force at 0.5 MPa.
Gate Actuation
Operates safety covers and machine gates where the SUS304 rod provides excellent moisture resistance.
Material Ejection
Pushes lightweight workpieces out of machining centers using adjustable end cushions to soften impacts.
Is the Airtac SAI32 Standard Cylinder SAI32BX325 the Right Cylinder?
Choose this 32 mm bore when an application requires roughly 400 N of push force at 0.5 MPa. If your project demands less energy, stepping down is an option, but moving up to a 40 mm bore increases the 0.5 MPa push force to 628 N for heavier payloads. For this 325 mm stroke, managing side load is critical; long unsupported rods are prone to bending under lateral forces. Employ external guide rails or select a guided cylinder to prevent premature rod-bearing wear.
Because this is a double-acting pneumatic actuator, air drives the piston in both directions. Be aware that standard SAI cylinders do not hold position pneumatically; if air pressure drops, the load will drift. For suspended loads requiring fail-safe holding, consider the SAIL variant with an air-released lock or an external pilot check valve. This model is dimensionally interchangeable per ISO 15552, accepting standard FA flange 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 SAI32 Standard Cylinder SAI32BX325 FAQ
At an operating pressure of 0.5 MPa, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At 0.7 MPa, the push force increases to 563 N.
Yes, the SAI32X325 is dimensionally interchangeable per ISO 15552. You can drop it into existing ISO 15552 mounting interfaces using standard accessories, though it is not identical to any specific brand's part.
