About the Airtac SAI32 Standard Cylinder SAI32BX145
The AirTAC SAI32X145 is a double-acting ISO 15552 profile cylinder engineered to deliver 402 N of push force at 0.5 MPa. Its 145 mm stroke is well-suited for compact automation tasks requiring precise linear movement. As a tie-rod-less extruded aluminum design, it provides a clean profile while maintaining strict dimensional interchangeability with other ISO 15552 cylinders.
This specific configuration features a SUS304 stainless steel piston rod (material code B) for superior corrosion resistance in humid or washdown environments. It utilizes PT tapered port threads, and because it lacks the -S magnet suffix, it is optimized for purely mechanical actuation without integrated sensor tracking.

Where the Airtac SAI32 Standard Cylinder SAI32BX145 Is Used
Small Part Ejection
Uses 402 N of push force at 0.5 MPa to reliably eject small molded components from machining centers.
Package Diverting
Actuates a diverter arm over a 145 mm stroke to route lightweight packages on a sorting line.
Clamp Actuation
Provides the linear motion needed to close low-friction secondary clamps on a packaging fixture.
Is the Airtac SAI32 Standard Cylinder SAI32BX145 the Right Cylinder?
Choose this 32 mm bore when an application demands around 400 N of push force at 0.5 MPa. If your assembly requires less energy, stepping down is difficult as this is the smallest standard SAI size, but stepping up to the 40 mm bore increases the push force significantly to 628 N at 0.5 MPa. The 145 mm stroke falls below the 300 mm threshold, so standard rod bearing bending is minimal.
Being a true ISO 15552 cylinder, this unit serves as a direct replacement matching the standard mounting interface, 145 mm stroke, and PT G1/8 port size. You can pair it with standard mounting accessories like LB foot brackets or FA flanges. Remember that standard double-acting cylinders drift downward if air pressure is lost; for applications requiring strict load holding, consider the SAIL variant with an air-released lock or an external pilot 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 SAI32BX145 FAQ
