About the Airtac SAI32 Standard Cylinder SAI32AX155S
The AirTAC SAI32X155-S is a double-acting ISO 15552 profile cylinder offering 402 N of push force at 0.5 MPa and up to 724 N at 0.9 MPa. Its 155 mm stroke is well-suited for compact clamping, indexing, and small parts handling tasks. The extruded aluminum barrel design omits traditional tie-rods, providing a clean exterior that simplifies mounting in tight machinery spaces.
Built to exacting dimensional standards, this unit is a direct replacement for other ISO 15552 cylinders. It features a SUS420J2 stainless steel piston rod for enhanced corrosion resistance over standard carbon steel. The integrated -S magnet allows seamless position detection using CMSE or DMSE series reed switches fitted directly into the dual sensor grooves on the barrel.

Where the Airtac SAI32 Standard Cylinder SAI32AX155S Is Used
Small Parts Clamping
Provides reliable 402 N clamping force at 0.5 MPa for securing lightweight aluminum or plastic components during CNC milling and drilling operations.
Package Sorting Diverter
The 155 mm stroke actuates diverter arms on packaging lines to route small cartons, utilizing the integrated magnet for precise end-position confirmation.
Pneumatic Ejection
Ideal for ejecting molded parts from small presses, with the SUS420J2 rod offering good wear resistance against minor abrasive contact.
Is the Airtac SAI32 Standard Cylinder SAI32AX155S the Right Cylinder?
Choose this 32 mm bore when your application requires less thrust than the 40 mm bore (which provides 628 N at 0.5 MPa) but more than smaller compact cylinders. The 155 mm stroke provides adequate travel for mid-range positioning. For applications requiring positive load holding upon air loss, note that the standard adjustable air cushions only decelerate the piston at end-of-stroke and do not function as a lock; consider the SAIL variant with an air-released lock or an external rod lock for fail-safe holding.
Because the 155 mm stroke is below the 300 mm threshold, side-load bending stresses on the rod bearing are minimal. Ensure your plumbing matches the PT tapered port standard (G1/8) and utilize standard ISO 15552 mounting accessories like LB foot brackets or FA flanges for secure installation.
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.
