About the Airtac SAI32 Standard Cylinder SAI32BX65S
The AirTAC SAI32X65-S is a double-acting ISO 15552 profile cylinder engineered for compact automation. Delivering a push force of 402 N at 0.5 MPa, this 32 mm bore unit is tailored for short 65 mm stroke movements. The extruded aluminum barrel design omits tie rods, providing a clean exterior that drops directly into standardized ISO 15552 mounting footprints.
This specific configuration includes a SUS304 stainless steel piston rod (material code B) for superior corrosion resistance in humid or washdown environments. It is equipped with a magnetic piston (-S) for position detection, seamlessly interfacing with CMSE or DMSE reed switches fitted into the dual sensor grooves machined along the barrel. Fluid connections use PT tapered threads.

Where the Airtac SAI32 Standard Cylinder SAI32BX65S Is Used
Small Part Ejection
Provides the 402 N push force needed to eject small molded components from a fixture quickly over a 65 mm travel distance.
Package Diverting
Actuates a short-stroke diverter arm on a packaging line, using the magnetic piston to confirm retraction before the next box passes.
Clamp Actuation
Secures lightweight aluminum extrusions during sawing, relying on the SUS304 rod to resist coolant moisture and corrosion.
Is the Airtac SAI32 Standard Cylinder SAI32BX65S the Right Cylinder?
Selecting this 32 mm bore is optimal when your application requires 402 N of push force at 0.5 MPa. If your mechanism demands heavier thrust, stepping up to the 40 mm bore increases that output to 628 N. Conversely, lighter duties might warrant smaller non-ISO alternatives. The 65 mm stroke offers quick, precise actuation without introducing significant rod-bearing bending. Because this is a double-acting pneumatic cylinder, it cannot hold a load mechanically if air pressure is lost; the piston will drift. For position-holding safety, consider the SAIL variant with an air-released lock. To match this exact unit for a replacement, specify: 32 mm bore, 65 mm stroke, PT port threads, and the -S magnet option.
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 SAI32BX65S FAQ
At a standard 0.5 MPa operating pressure, this 32 mm bore cylinder generates 402 N of push force and 345 N of pull force. If pressure is increased to 0.7 MPa, the push force rises to 563 N.
Yes. The SAI32X65-S is built to the ISO 15552 dimensional standard, making it a direct replacement for other ISO 15552 profile cylinders of the same bore and stroke. Ensure your mounting accessories and PT port threads align.
