About the Airtac SAI32 Standard Cylinder SAI32BX155S
The AirTAC SAI32X155-S is a double-acting ISO 15552 profile cylinder featuring a 32mm bore and a 155mm stroke. Because 155mm falls outside the standard 25mm increments, this is a made-to-order unit tailored for specific travel requirements. It delivers 402N of push force at 0.5 MPa, making it well-suited for compact, mid-distance actuation tasks.
This variant is configured with a SUS304 stainless steel rod for superior corrosion resistance and includes a built-in magnet (-S) for use with CMSE and DMSE reed switches. The extruded aluminum barrel incorporates sensor grooves on both sides for flexible mounting, and the unit uses PT tapered port threads.

Where the Airtac SAI32 Standard Cylinder SAI32BX155S Is Used
Compact Part Ejection
Provides the precise 155mm travel needed to push finished small parts out of a machining center using 402N of force at 0.5 MPa.
Corrosive Environment Handling
The SUS304 stainless steel rod stands up to moisture and coolants when actuating grippers or diverters in wash-down packaging zones.
Package Sorting Diverter
Uses the integrated magnet with DMSE sensors to confirm stroke positions while routing light cardboard cartons along a conveyor line.
Is the Airtac SAI32 Standard Cylinder SAI32BX155S the Right Cylinder?
Choose this 32mm bore when an application requires roughly 400N of push force at 0.5 MPa. If your project needs less force, stepping down is not an option within the SAI range, but stepping up to the 40mm bore yields 628N at 0.5 MPa for heavier payloads. Because this 155mm stroke is a non-standard length, expect a slightly longer lead time for made-to-order manufacturing.
As a true ISO 15552 profile cylinder, this model is dimensionally interchangeable with other ISO 15552 cylinders of the same bore and stroke. It uses PT ports, accepts standard mounting accessories like FA flanges or LB foot brackets, and the included magnet allows seamless integration with position sensors. Note that a standard SAI relies on air pressure to maintain its position; if power drops, the load will drift. For dead-end holding, consider the SAIL lock variant.
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 SAI32BX155S FAQ
At an operating pressure of 0.5 MPa, this 32mm bore cylinder generates 402N of push force and 345N of pull force. If you increase the pressure to 0.7 MPa, the push force rises to 563N.
Yes. The SAI32X155-S is built to the ISO 15552 standard, meaning its mounting dimensions are fully interchangeable with other ISO 15552 profile cylinders of the same bore size, allowing for a direct replacement.
