About the Airtac SAI32 Standard Cylinder SAI32AX280S
The AirTAC SAI32X280-S is a double-acting ISO 15552 profile cylinder offering 402 N of push force at 0.5 MPa. Its 280 mm stroke provides ample extension for packaging and small automation tasks. The extruded aluminum barrel design omits tie rods for a clean exterior.
This specific configuration includes a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance in humid environments. The -S suffix indicates an integrated magnet, allowing seamless position detection using CMSE or DMSE reed switches along the dual sensor grooves. Ports feature PT tapered threading.

Where the Airtac SAI32 Standard Cylinder SAI32AX280S Is Used
Package Sorting
Pushes small to medium parcels on a sorting line using the 280 mm stroke and 563 N force at 0.7 MPa.
Component Feeding
Advances lightweight metal parts into a CNC machining center with reliable magnetic position feedback.
Pallet Handling
Indexes empty pallets into a wrapping station where the SUS420J2 rod resists ambient moisture.
Is the Airtac SAI32 Standard Cylinder SAI32AX280S the Right Cylinder?
If an application requires less extension or higher compactness, stepping down to a standard 250 mm stroke reduces overall length while maintaining the same 402 N output. For heavier loads requiring more thrust, moving up to a 40 mm bore increases force to 628 N at 0.5 MPa.
Because this 280 mm stroke exceeds 300 mm when fully extended, it is susceptible to rod-bearing bending under side loads; utilizing an external guide rail or a guided cylinder body is strongly recommended. This unit is dimensionally interchangeable with other ISO 15552 cylinders. It utilizes a PT port thread, a 12 mm rod, and an M10x1.25 rod thread. Note that the adjustable air cushions only decelerate the piston at end-of-stroke; this cylinder will drop its load if air pressure is lost. For position 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.
Airtac SAI32 Standard Cylinder SAI32AX280S FAQ
