About the Airtac SAI32 Standard Cylinder SAI32AX850
The AirTAC SAI32X850 is a double-acting ISO 15552 profile cylinder engineered for extended reach applications. Operating at 0.5 MPa, it generates 402 N of push force and 345 N of pull force, making it suitable for light-duty positioning tasks. This 32 mm bore unit features an 850 mm stroke and operates reliably at speeds between 30 and 800 mm/s.
This specific configuration utilizes an SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance compared to standard carbon steel. It uses PT tapered port threads, and because it lacks the -S magnet suffix, it is optimized for pure actuation rather than electronic position sensing.

Where the Airtac SAI32 Standard Cylinder SAI32AX850 Is Used
Long-Reach Diverting
Pushes lightweight packages across a 850 mm conveyor belt span with precise 402 N force at 0.5 MPa.
High-Bay Ejection
Extends deep into storage racks to eject small totes, utilizing the 850 mm stroke to access hard-to-reach bins.
Film Roll Handling
Transfers packaging film rolls horizontally, relying on the SUS420J2 stainless rod to resist humid environmental conditions.
Is the Airtac SAI32 Standard Cylinder SAI32AX850 the Right Cylinder?
Choosing this 850 mm stroke model requires careful attention to mechanical guidance. At this extended length, the unsupported piston rod is highly susceptible to bending under side loads; utilizing an external guide rail or a dedicated guided cylinder system is strongly recommended to prevent premature rod-bearing wear.
For applications requiring higher force, stepping up to a 40 mm bore increases output to 628 N at 0.5 MPa. As a true ISO 15552 profile cylinder, this unit serves as a direct replacement for any standard 32 mm bore, 850 mm stroke, PT ported cylinder with matching mounting accessories like FA flanges or LB foot brackets. Note that standard air cushions only decelerate the piston at end-of-stroke and will not hold a load if air pressure is lost; use a SAIL locking variant for fail-safe positioning.
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.
