About the Airtac SAI200 Standard Cylinder SAI200AX170S
The AirTAC SAI200X170-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. At 200mm bore, it generates a robust 15708N push and 15080N pull force at 0.5 MPa. The 170mm stroke provides substantial extension for large-scale press and lift operations.
This specific configuration includes a SUS420J2 stainless steel piston rod (material code A) for superior corrosion resistance in humid or washdown environments. It features PT tapered port threads and an integrated magnet (-S) for direct mounting of CMSE or DMSE sensor switches along the dual grooves on the extruded aluminum barrel.

Where the Airtac SAI200 Standard Cylinder SAI200AX170S Is Used
Heavy Stamping Presses
Provides the massive 15708N push force required to actuate large metal forming and stamping presses at 0.5 MPa.
Automotive Lift Gates
The 170mm stroke and high load capacity make it suitable for raising and lowering heavy industrial vehicle lift gates.
Large Mold Handling
Shifts substantial injection or cast molds along machine beds, utilizing the SUS420J2 rod for environmental resilience.
Is the Airtac SAI200 Standard Cylinder SAI200AX170S the Right Cylinder?
Selecting this 200mm bore over the 160mm variant increases your 0.5 MPa push force from 10053N to 15708N, ideal when overcoming massive static loads. Conversely, stepping down to the 160mm bore reduces physical envelope and air consumption if 10kN is sufficient. Because the 170mm stroke is below the 300mm threshold, rod-bearing bending stress is minimal, though external guides are still recommended for heavy offset loads.
As a true ISO 15552 profile cylinder, it offers drop-in dimensional interchangeability with other ISO 15552 compliant actuators. Note that standard double-acting cylinders drift when air pressure is removed; if your application requires fail-safe load holding without live pressure, consider the BSAI clamp-lock or SAIL locking variants instead of relying on the adjustable air cushions, which only decelerate the piston near stroke end.
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 SAI200 Standard Cylinder SAI200AX170S FAQ
At 0.5 MPa operating pressure, this 200mm bore cylinder provides 15708N of push force and 15080N of pull force. At 0.7 MPa, the push force increases to 21991N.
No, the adjustable air cushions only decelerate the piston near the end of the stroke and do not lock the load. If you need to hold a vertical load without live air pressure, use the SAIL or BSAI variants, or install an external rod lock.
