About the Airtac SAI32 Standard Cylinder SAI32X400S
The AirTAC SAI32X400-S is a double-acting ISO 15552 profile cylinder featuring a 32mm bore and a 400mm stroke. It generates 402N of push force at 0.5 MPa, making it well-suited for standard linear actuation tasks over extended distances.
This variant includes a standard magnet for position sensing, utilizing the dual sensor grooves on the extruded aluminum barrel to accept CMSE or DMSE switches. The piston rod is constructed from carbon steel, and the pneumatic supply connects via a PT tapered G1/8 port.

Where the Airtac SAI32 Standard Cylinder SAI32X400S Is Used
Material Transfer
Pushes light product packages between conveyor belts over a 400mm gap with 402N of push force at 0.5 MPa.
Parts Ejection
Ejects small molded components from a press area, utilizing the magnetic piston for end-of-stroke confirmation.
Light Assembly
Actuates a lightweight tooling plate forward and back during small electronic component placement.
Is the Airtac SAI32 Standard Cylinder SAI32X400S the Right Cylinder?
If your application requires slightly less reach, the SAI32X300-S offers a shorter 300mm stroke with the same 402N push force at 0.5 MPa. Stepping up to a 40mm bore increases the push force to 628N at 0.5 MPa, which is preferable if the load resistance is higher than expected.
Because this 400mm stroke creates an extended lever arm, side loads can cause excessive bending stress on the rod bearing. Utilizing an external guide rail or a fully guided cylinder is strongly recommended to prevent premature wear. To maintain ISO 15552 interchangeability, match the 32mm bore, 400mm stroke, G1/8 PT port, and the -S magnet option. Note that this cylinder relies on live air pressure to move; it cannot hold a load if air is exhausted. For dead-end holding, consider the SAIL locking 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.
