About the Airtac SAI32 Standard Cylinder SAI32AX425S
The AirTAC SAI32X425-S is a double-acting ISO 15552 profile cylinder offering a practical linear motion solution. It generates 402 N of push force at 0.5 MPa and 563 N at 0.7 MPa, making it well-suited for mid-length positioning tasks. The 425 mm stroke provides extended travel for packaging and handling machinery.
This variant features a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance. Equipped with a magnet (-S), it supports direct mounting of CMSE and DMSE sensor switches along the extruded aluminum barrel grooves. Fluid ports use PT tapered threads.

Material Handling
Actuates lifting and transferring mechanisms in automated storage and retrieval systems.
Is the Airtac SAI32 Standard Cylinder SAI32AX425S the Right Cylinder?
Selecting this 32 mm bore cylinder is ideal when your application requires the 402 N force class at 0.5 MPa but needs more travel than a standard 300 mm stroke offers. If your process demands higher thrust, stepping up to the 40 mm bore yields 628 N at 0.5 MPa. Conversely, lighter duties can utilize smaller bores.
Because the 425 mm stroke creates a long unsupported rod extension, side loads can cause rod-bearing bending. Use external guide rails or a fully guided cylinder to prevent premature wear. For applications requiring load holding during air pressure loss, integrate an external rod lock or specify the SAIL 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.
