About the Airtac SAI32 Standard Cylinder SAI32BX850S
The AirTAC SAI32X850-S is a double-acting ISO 15552 profile cylinder featuring a 32mm bore and an 850mm stroke. It delivers a push force of 402N at 0.5 MPa, extending to 724N at 0.9 MPa, making it well-suited for long-travel actuation in compact spaces. As a genuine AirTAC component, it provides reliable performance for demanding automation environments.
This specific configuration includes a SUS304 stainless steel piston rod (material code B) for superior corrosion resistance and a built-in magnet for use with CMSE and DMSE series sensor switches. The extruded aluminum barrel features sensor grooves on both sides, and fluid connections use PT tapered threads.

Where the Airtac SAI32 Standard Cylinder SAI32BX850S Is Used
Long-Reach Diverting
Ideal for pushing products across wider conveyor belts where an 850mm travel distance is required to span multiple lanes.
High-Bay Extraction
Extracts totes or cartons from deep storage shelving, utilizing the 32mm bore's compact footprint and 850mm extension.
Film Web Handling
Moves winding carriages or cutting heads across wide material webs, benefiting from the SUS304 rod's corrosion resistance.
Is the Airtac SAI32 Standard Cylinder SAI32BX850S the Right Cylinder?
When selecting this actuator, consider that a 32mm bore offers lower thrust compared to stepping up to a 40mm bore, which provides 628N at 0.5 MPa. If your application requires less force and a shorter stroke, a 32mm bore remains highly efficient. However, for higher load demands, increasing the bore size is advisable.
Because this model has an 850mm stroke, the unsupported piston rod is susceptible to bending under side loads. To prevent rod-bearing damage, use an external guide rail or a guided cylinder to absorb lateral forces. Note that this standard cylinder does not hold position when air pressure is lost; for dead-end holding, explore the SAIL lock variant. It serves as a dimensionally interchangeable direct replacement for other ISO 15552 cylinders, utilizing a PT G1/8 port and standard mounting accessories like FA or LB.
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.
