About the Airtac SAI32 Standard Cylinder SAI32AX650S
The AirTAC SAI32X650-S is a double-acting ISO 15552 profile cylinder engineered for extended reach operations. Delivering a push force of 402 N at 0.5 MPa and 563 N at 0.7 MPa, this 32 mm bore unit provides reliable linear motion across its 650 mm stroke. It features an extruded aluminum barrel without tie-rods, ensuring a clean exterior that drops directly into standardized ISO 15552 mounting footprints.
This specific configuration includes an SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance compared to standard carbon steel. Equipped with a magnet (-S), it supports CMSE and DMSE sensor switches housed within the dual grooves machined into both sides of the barrel. Fluid connections utilize PT tapered threads, and the cylinder incorporates adjustable air cushions at both ends to dampen impact at stroke extremes.

Where the Airtac SAI32 Standard Cylinder SAI32AX650S Is Used
Extended Transfer Pushing
Ideal for pushing components along lengthy conveyor sections where a 650 mm reach is required, utilizing the 563 N force at 0.7 MPa to move lightweight packages reliably.
Material Diversion Gates
Actuates diverter arms in sorting stations. The dual sensor grooves allow flexible placement of DMSE switches to confirm gate position across the long stroke.
Long-Reach Part Ejection
Ejects machined parts from deep work zones. The SUS420J2 stainless rod provides necessary resilience against minor moisture and shop environment contaminants.
Is the Airtac SAI32 Standard Cylinder SAI32AX650S the Right Cylinder?
Selecting this 650 mm stroke model requires careful attention to mechanical guidance. At this extension length, the 12 mm rod is 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. If an application requires less reach, stepping down to a standard 500 mm stroke reduces overall envelope size while maintaining the same 402 N thrust at 0.5 MPa.
For operations needing 628 N of push force at 0.5 MPa, the SAI40X650-S offers a direct upgrade path, though it requires G1/4 ports instead of the G1/8 ports found on this 32 bore unit. Remember that the integrated air cushions only decelerate the piston near the end of travel; they do not function as a locking mechanism. If the system loses air pressure, the rod will drift, requiring an external pilot-operated check valve or a SAIL variant to secure the load safely.
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 SAI32AX650S FAQ
This 32 mm bore cylinder generates a push force of 402 N at 0.5 MPa, 563 N at 0.7 MPa, and 724 N at 0.9 MPa. The pull force at 0.5 MPa is 345 N.
Yes, the SAI32X650-S is dimensionally interchangeable per ISO 15552. You can drop it into existing mounts matching the standard, provided you accommodate the PT port threads and G1/8 port size.
