About the Airtac SAI32 Standard Cylinder SAI32BX155
The AirTAC SAI32X155 is a double-acting ISO 15552 profile cylinder engineered for standardized mounting. Delivering a push force of 563 N at 0.7 MPa, this 32 mm bore unit is built around an extruded aluminum barrel without tie-rods. The 155 mm stroke provides a compact extension length ideal for light-duty automation tasks.
This specific configuration utilizes a SUS304 stainless steel piston rod (material code B) for superior corrosion resistance in humid or washdown environments. It features PT tapered port threads and lacks a standard magnet, meaning it is optimized for pure mechanical actuation without direct position sensing.

Where the Airtac SAI32 Standard Cylinder SAI32BX155 Is Used
Package Diverting
Provides the precise 155 mm stroke needed to push small cartons off a sorting line using 563 N of force.
Small Part Ejection
Ejects lightweight plastic or aluminum components from a molding press without risking corrosion thanks to the SUS304 rod.
Gripping Stopper
Acts as a pneumatic stopper arm for pallets or totes in a compact conveyor system where space is limited.
Is the Airtac SAI32 Standard Cylinder SAI32BX155 the Right Cylinder?
Select this 32 mm bore when an application requires exactly 563 N of push force at 0.7 MPa. If your fixture demands less energy, stepping down is not an option as this is the smallest SAI size, but stepping up to the 40 mm bore yields 879 N at the same pressure. Because the stroke is 155 mm, side-load stress on the rod bearing remains low, though external guides are always recommended if heavy off-center loads are attached.
As a true ISO 15552 cylinder, this model serves as a direct replacement for any standard 32 mm bore, 155 mm stroke, PT ported profile cylinder using standard FA, FB, LB, or TC mounting accessories. If the machinery requires the piston to stay put after a pressure loss, note that the standard SAI will drift; an external pilot-operated check valve or the SAIL locking variant is required for holding.
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 SAI32BX155 FAQ
At a standard operating pressure of 0.7 MPa, this 32 mm bore cylinder produces a push force of 563 N and a pull force of 345 N. It can reach a maximum theoretical force of 82 kgf at 1.0 MPa.
This specific configuration does not include a magnet (-S), so it cannot host CMSE or DMSE electronic sensors. If position detection is required, you must select the SAI32X155-S variant or use external mechanical limit switches.
