About the Airtac SAI200 Standard Cylinder SAI200AX350
The AirTAC SAI200X350 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. It delivers a substantial push force of 15708 N and a pull force of 15080 N at 0.5 MPa, making it suitable for high-mass positioning tasks. The 350 mm stroke provides ample travel for large presses and material handling systems.
This model features a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance compared to standard carbon steel. The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of CMSE or DMSE switches. Note that this configuration uses PT tapered ports and is supplied without a magnet.

Where the Airtac SAI200 Standard Cylinder SAI200AX350 Is Used
Heavy Stamping Presses
Provides the immense 15708 N push force required to actuate large metal forming and stamping presses.
Large Mold Handling
Moves heavy injection molds into and out of machining centers with precise 350 mm travel.
Bulk Material Diversion
Drives heavy-duty diverter arms on bulk material conveyor lines to sort large industrial components.
Is the Airtac SAI200 Standard Cylinder SAI200AX350 the Right Cylinder?
Selecting this 200 mm bore cylinder is ideal when applications require up to 15708 N of thrust at 0.5 MPa. If your load requirements are lower, stepping down to the 160 mm bore variant provides 10053 N of push force, which may offer a more compact and economical footprint. Conversely, ensure your pneumatic supply can adequately feed the G3/4 port to maintain operational speeds within the 30-500 mm/s range.
With a 350 mm stroke, the extended rod is susceptible to bending under side loads. We recommend using an external guide rail or a fully guided cylinder to prevent premature rod-bearing wear. For applications that must hold a load in place during a complete loss of air pressure, a standard SAI cylinder will drift; you should specify the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variant instead. This model is dimensionally interchangeable per ISO 15552 standards, serving as a direct drop-in replacement for other ISO 15552 profile 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.
Airtac SAI200 Standard Cylinder SAI200AX350 FAQ
