About the Airtac SAI200 Standard Cylinder SAI200AX140S
The AirTAC SAI200X140-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty motion tasks, generating 15708 N of push force at 0.5 MPa. With a 200 mm bore and 140 mm stroke, this extruded aluminum barrel design omits traditional tie rods for a rigid yet streamlined assembly. The integrated -S magnet enables direct mounting of CMSE or DMSE sensor switches along the dual grooves on the barrel sides.
Built for demanding environments, this specific configuration features a SUS420J2 stainless steel piston rod (material code A) for superior corrosion and scratch resistance compared to standard carbon steel. Fluid is filtered 40 um air, operating pressure is 0.15-1.0 MPa, and the PT tapered port threads ensure a robust, leak-free connection in high-vibration installations.

Where the Airtac SAI200 Standard Cylinder SAI200AX140S Is Used
Heavy Metal Forming
Provides the immense 15708 N push force at 0.5 MPa required for stamping, pressing, and bending heavy-gauge metal components in automated fabrication lines.
Large Mold Handling
Actuates massive injection mold bases or heavy tooling fixtures with precise 140 mm travel, utilizing the SUS420J2 rod for durability against side loads.
Automotive Assembly
Drives large-scale robotic welding fixtures and heavy component positioning systems where robust PT port threads and high-pressure capacity are mandatory.
Is the Airtac SAI200 Standard Cylinder SAI200AX140S the Right Cylinder?
Selecting the 200 mm bore is ideal when an application demands extreme thrust that smaller bores cannot provide, such as stepping up from a 160 mm bore that yields 10053 N at 0.5 MPa. The 140 mm stroke is well within the 1500 mm standard limit, keeping the assembly compact while delivering massive force.
Because this is a double-acting cylinder, it relies on continuous air pressure to move and hold loads; if pressure is lost, the piston will drift. For applications requiring true position holding without live pressure, consider the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variants. This SAI200X140-S is dimensionally interchangeable per ISO 15552, meaning it serves as a direct drop-in replacement for other ISO 15552 profile cylinders with matching 200 mm bore, 140 mm stroke, G3/4 port, and appropriate mounting accessories like FA/FB flanges.
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 SAI200AX140S FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder generates 15708 N of push force and 15080 N of pull force. At 0.7 MPa, the push force increases to 21991 N.
Yes, the -S suffix indicates this model includes a magnet and is fully compatible with CMSE and DMSE series sensor switches, which mount directly into the grooves on both sides of the extruded aluminum barrel.
