About the Airtac SAI32 Standard Cylinder SAI32AX250S
The AirTAC SAI32X250-S is a double-acting ISO 15552 profile cylinder offering 402 N of push force at 0.5 MPa. Its 250 mm stroke is well-suited for medium-travel material handling tasks. This variant includes a magnet for proximity sensing and utilizes a SUS420J2 stainless steel piston rod for enhanced corrosion resistance.
Because it is a genuine AirTAC component, this actuator guarantees a direct replacement for other ISO 15552 profile cylinders. The extruded aluminum barrel features dual sensor grooves, allowing seamless integration with CMSE or DMSE reed switches without requiring additional brackets.

Where the Airtac SAI32 Standard Cylinder SAI32AX250S Is Used
Package Sorting Diverter
Provides reliable 250 mm travel to push small to medium parcels between sorting lanes at high cycling speeds.
Small Component Ejection
Delivers 402 N of thrust to eject machined plastic or light metal parts from a fixture during automated manufacturing.
Tray Indexing Pusher
Indexes empty packaging trays into a filling station, using the integrated magnet for end-of-stroke position confirmation.
Is the Airtac SAI32 Standard Cylinder SAI32AX250S the Right Cylinder?
If your application requires less extension, stepping down is not an option from the 32 mm bore as it is the smallest size, but moving up to a 40 mm bore increases the 0.5 MPa push force to 628 N. For this 250 mm stroke, the unsupported piston rod is susceptible to bending under side loads; utilizing an external guide rail or a twin-rail guided cylinder prevents premature rod-bearing wear.
This SAI32X250-S configuration uses PT tapered port threads and operates at speeds between 30 and 800 mm/s. Remember that a standard double-acting cylinder drifts when air pressure is removed; utilize the SAIL variant if your machinery requires a mechanical lock to hold a load safely during an air-loss event.
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.
