About the Airtac SAI32 Standard Cylinder SAI32BX145S
The AirTAC SAI32X145-S is a double-acting ISO 15552 profile cylinder featuring a 32mm bore and a custom 145mm stroke. It delivers a push force of 402N at 0.5 MPa and 563N at 0.7 MPa, making it well-suited for compact automation tasks requiring precise mid-length movements.
Configured to order, this unit incorporates a SUS304 stainless steel rod for superior corrosion resistance and includes a magnetic piston (-S) for direct compatibility with CMSE and DMSE sensor switches. The extruded aluminum barrel integrates sensor grooves on both sides, while fluid connections utilize PT tapered threads.

Where the Airtac SAI32 Standard Cylinder SAI32BX145S Is Used
Compact Assembly
Drives small clamps and actuators on semiconductor assembly lines where a 145mm stroke and SUS304 rod resist moisture.
Package Diverting
Pushes light parcels off a conveyor belt utilizing 402N of push force at 0.5 MPa with precise magnetic position feedback.
Grippers
Actuates pneumatic grippers in tight robotic cells, relying on the compact 32mm ISO 15552 profile barrel.
Is the Airtac SAI32 Standard Cylinder SAI32BX145S the Right Cylinder?
Selecting this 32mm bore is ideal when your application requires around 402N of push force at 0.5 MPa. If your project demands less thrust, stepping down is an option, but moving up to a 40mm bore increases that output to 628N. Because this unit features a 145mm non-standard stroke, ensure your design accommodates the exact extension length.
For load holding, note that a standard double-acting cylinder will drift if air pressure is lost; utilize the SAIL locking variant if the mechanism must hold position safely. This SAI32X145-S serves as a dimensionally interchangeable direct replacement for other ISO 15552 cylinders, matching the 32mm bore, 145mm stroke, PT port, and standard mounting accessories like LB foot or FA flange, complete with the -S magnet.
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.
