About the Airtac SAI125 Standard Air Cylinder SAI125AX60
The AirTAC SAI125X60 is a double-acting ISO 15552 profile cylinder engineered for high-force pneumatic tasks, delivering a push force of 6136 N at 0.5 MPa. Its 60 mm stroke is a made-to-order dimension tailored for compact, heavy-duty actuation where standard lengths are unsuitable. The extruded aluminum barrel design omits tie rods, providing a sleek profile while maintaining strict dimensional interchangeability with other ISO 15552 cylinders.
This specific configuration features a SUS420J2 stainless steel piston rod (material code A), offering superior corrosion resistance compared to standard carbon steel. Fluid and air connections utilize PT tapered threads, ensuring robust sealing in high-flow pneumatic circuits. Since a magnet is not specified, this variant is configured for standard actuation without internal position sensing.

Where the Airtac SAI125 Standard Air Cylinder SAI125AX60 Is Used
Heavy-Duty Stamping
Provides the robust 6136 N thrust required for short-stroke metal forming and pressing operations in confined machinery spaces.
Industrial Pressing
Ideal for compacting and riveting assemblies where a brief 60 mm stroke delivers high-impact clamping force.
Heavy Clamp Actuation
Secures large workpieces or heavy molds during machining, utilizing the 125 mm bore's substantial pull force of 5734 N at 0.5 MPa.
Is the Airtac SAI125 Standard Air Cylinder SAI125AX60 the Right Cylinder?
Selecting this 125 mm bore is ideal when 80 mm (2513 N at 0.5 MPa) lacks the thrust for heavy lifting, but stepping up to a 160 mm bore (10053 N) would be physically oversized for the machine envelope. For applications requiring position feedback, adding the -S magnet option allows integration with CMSE or DMSE sensor switches mounted in the dual side grooves. If the machinery must hold a load statically without continuous air pressure, the standard SAI cannot lock the piston; consider the SAIL variant with an air-released lock or the BSAI bidirectional clamp-lock cylinder for fail-safe positioning.
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.
