About the Airtac SAI125 Standard Air Cylinder SAI125AX600S
The AirTAC SAI125X600-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. It provides a substantial push force of 8590 N at 0.7 MPa, making it well-suited for moving large masses over its 600 mm travel distance. 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 production environments. Equipped with a -S magnet, the barrel features sensor grooves on both sides for seamless mounting of CMSE or DMSE reed switches. Fluid connections use PT tapered threads.

Where the Airtac SAI125 Standard Air Cylinder SAI125AX600S Is Used
Pallet Handling
Extends 600 mm to push heavy pallets along accumulation conveyors in distribution centers, utilizing its 6136 N force at 0.5 MPa.
Automotive Press
Positions large stamping blanks or composite molds within automotive assembly lines, benefiting from the robust SUS420J2 rod.
Automated Storage
Drives heavy shelving carts or lifting platforms in automated high-bay warehousing systems over a 600 mm extension.
Is the Airtac SAI125 Standard Air Cylinder SAI125AX600S the Right Cylinder?
At 0.5 MPa this bore yields 6136 N of push force; if your application requires less energy, stepping down to a 100 mm bore provides 3927 N. Because this 600 mm stroke is substantial, an unsupported rod is highly susceptible to bending under side loads. Employ an external guide rail or a fully guided cylinder to prevent premature rod-bearing wear.
If the machinery loses air pressure, this standard cylinder cannot hold a suspended load and will drift downward. For fail-safe holding, integrate the SAIL pneumatic lock variant or an external rod lock. As a true ISO 15552 profile cylinder, it serves as a dimensionally interchangeable drop-in replacement for other ISO 15552 standard cylinders, utilizing PT ports and standard mounting accessories like TC trunnions.
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.
