About the Airtac SAI32 Standard Cylinder SAI32BX15
The AirTAC SAI32X15 is a double-acting ISO 15552 profile cylinder engineered for compact actuation, delivering 402 N of push force at 0.5 MPa. Because the 15 mm stroke falls below the standard 25 mm minimum, it is manufactured as a special non-standard stroke order to fit extremely tight spaces. The extruded aluminum barrel design omits tie rods, providing a clean exterior that drops seamlessly into existing ISO 15552 mounting footprints.
This specific configuration features a SUS304 stainless steel piston rod (material code B) for superior corrosion resistance in washdown or chemically exposed environments. It utilizes PT tapered port threads and does not include a magnet, meaning it is optimized purely for mechanical force transmission rather than electronic position sensing.

Where the Airtac SAI32 Standard Cylinder SAI32BX15 Is Used
Short-Stroke Clamping
Ideal for holding lightweight components in machining or assembly fixtures where only 15 mm of travel is needed to secure the part.
Package Ejection
Provides a rapid 402 N push to divert or eject small items from a conveyor line without extending into adjacent machinery lanes.
Valve Actuation
Suitable for automating small process valves or gates where a compact, corrosion-resistant SUS304 rod is required.
Is the Airtac SAI32 Standard Cylinder SAI32BX15 the Right Cylinder?
Selecting this 32 mm bore is ideal when 402 N at 0.5 MPa is sufficient, allowing you to step down from a 40 mm bore (which outputs 628 N) to save valuable space and air consumption. The 15 mm stroke is purpose-built for short clamping or ejecting tasks where a standard 25 mm travel would bottom out or require excessive spacing.
Because the standard SAI lacks a locking mechanism, the piston will drift if air pressure is lost; use the SAIL variant if your application requires pneumatic end-locking to hold a load safely. To replace this unit, match the 32 mm bore, 15 mm stroke, PT G1/8 port, and choose your mounting accessory such as an LB foot or FA flange.
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 SAI32BX15 FAQ
At 0.5 MPa operating pressure, the SAI32X15 generates 402 N of push force and 345 N of pull force. It can reach up to 724 N of push force at 0.9 MPa.
Yes, as a genuine ISO 15552 profile cylinder, its mounting dimensions are standardized. It serves as a direct replacement for other ISO 15552 cylinders with a 32 mm bore and G1/8 port, provided you account for the custom 15 mm stroke.
