About the Airtac SAI32 Standard Cylinder SAI32X350S
The AirTAC SAI32X350-S is a double-acting ISO 15552 profile cylinder offering 402 N of push force at 0.5 MPa. Its 350 mm stroke is well-suited for intermediate linear positioning tasks where space allows moderate extension. The extruded aluminum barrel design omits traditional tie rods, providing a clean exterior.
This specific configuration includes a magnetic piston (-S) for use with CMSE and DMSE series reed switches, enabling reliable end-of-stroke detection. The standard carbon steel piston rod provides robust service for general industrial automation, and the PT tapered port threads ensure a tight, leak-free pneumatic connection.

Is the Airtac SAI32 Standard Cylinder SAI32X350S the Right Cylinder?
Selecting this 32 mm bore cylinder makes sense when application forces require around 400 N of push or 345 N of pull at 0.5 MPa. If your assembly needs to lift heavier payloads, stepping up to the 40 mm bore yields 628 N of push force at the same pressure. Conversely, if the load is very light, dropping to a smaller bore might save air volume.
Because the 350 mm stroke creates a long unsupported rod when extended, side loads can cause severe bending stress on the rod bearing. To manage this, implement an external linear guide rail or use a guided cylinder to prevent premature seal wear and binding. Note that this cylinder cannot hold a load if air pressure is lost; for position holding, consider the SAIL locking variant or an external pilot-operated check valve. As a true ISO 15552 profile cylinder, it is dimensionally interchangeable with other ISO 15552 cylinders for direct replacement using PT ports and standard FA flange or LB foot mounts.
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 SAI32X350S FAQ
At 0.5 MPa operating pressure, the SAI32X350-S provides a push force of 402 N and a pull force of 345 N. If pressure is increased to 0.7 MPa, the push force reaches 563 N.
Yes, the SAI32X350-S is a genuine ISO 15552 profile cylinder, making its mounting dimensions and port locations fully interchangeable with other standard ISO 15552 cylinders, allowing for a seamless direct replacement.
