About the Airtac SAI32 Standard Cylinder SAI32BX35S
The AirTAC SAI32X35-S is a double-acting ISO 15552 profile cylinder engineered for compact, short-stroke automation. Delivering 402 N of push force at 0.5 MPa, it fits perfectly into tight machinery spaces. The extruded aluminum barrel design omits tie-rods, providing a clean exterior that drops right into standard ISO 15552 mounting footprints.
This specific configuration features a SUS304 stainless steel piston rod (option B) for superior corrosion resistance in washdown or chemically exposed environments. Equipped with a magnet (-S), it integrates seamlessly with CMSE and DMSE reed switches fitted into the dual sensor grooves on the barrel. The cylinder uses PT tapered port threading and adjustable air cushions at both ends to tame end-of-stroke impacts.

Where the Airtac SAI32 Standard Cylinder SAI32BX35S Is Used
Small Part Ejection
Uses the 35 mm stroke to rapidly push small machined components out of a fixture without overtravel, relying on the 402 N force to overcome friction.
Packaging Clamps
Secures light cardboard cartons during sealing operations, where the SUS304 rod prevents corrosion from occasional washdowns.
Sensor Actuation
Triggers mechanical limit arms or diverter gates in conveyor systems, utilizing the built-in magnet for position confirmation via DMSE switches.
Is the Airtac SAI32 Standard Cylinder SAI32BX35S the Right Cylinder?
Select this 32 mm bore when your application requires 402 N of push force at 0.5 MPa but is constrained by a very short 35 mm stroke. If you need slightly less force, stepping down is not an option below 32 mm in the SAI series, but stepping up to a 40 mm bore yields 628 N at 0.5 MPa if your load demands more authority. The 35 mm stroke is non-standard but well within the 1000 mm maximum for this bore, making it an ideal choice for precise clamping or ejecting without wasted travel.
Because the stroke is under 300 mm, rod-bearing bending stress is minimal, and you generally do not need external guide rails to support side loads. Keep in mind that a standard SAI cylinder relies on continuous air pressure to hold its position; if power drops, the load will drift. For dead-end holding without live pressure, specify the SAIL variant with an air-released lock or use an external pilot-operated check valve. This model is fully interchangeable with other ISO 15552 cylinders of the same bore and stroke, utilizing PT G1/8 ports and standard FA, LB, or TC mounting accessories.
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 SAI32BX35S FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder generates 402 N of push force and 345 N of pull force. If you increase the pressure to 0.7 MPa, the push force rises to 563 N.
Yes, the SAI32X35-S is dimensionally interchangeable per ISO 15552. You can use it as a direct replacement for other ISO 15552 profile cylinders with a 32 mm bore and 35 mm stroke, matching the G1/8 port and mounting dimensions exactly.
