About the Airtac SAI200 Standard Cylinder SAI200AX125S
The AirTAC SAI200X125-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a substantial 15708 N of push force at 0.5 MPa, this 200 mm bore unit is built to move massive loads reliably. The 125 mm stroke provides the precise travel distance needed for high-force clamping, pressing, and lifting tasks. This configuration includes a magnet for position sensing.
Beyond the standard thrust metrics, this specific variant is equipped with a SUS420J2 stainless steel piston rod (material code A), offering superior resistance to corrosion and surface wear in harsh industrial environments. It utilizes PT tapered port threads for a robust pneumatic connection, and the integrated magnet allows seamless operation with CMSE and DMSE series reed switches housed within the dual sensor grooves on the extruded aluminum barrel.

Where the Airtac SAI200 Standard Cylinder SAI200AX125S Is Used
Heavy Metal Stamping
Provides the 15708 N push force required to form and stamp thick-gauge metal components in automotive and structural fabrication lines.
Large Assembly Pressing
Delivers consistent 125 mm stroke pressing power for seating large bearings, bushings, and heavy machinery sub-assemblies.
Bulk Material Diverting
Actuates heavy-duty diverter arms and gating mechanisms on high-capacity mining or aggregate conveyor systems.
Is the Airtac SAI200 Standard Cylinder SAI200AX125S the Right Cylinder?
Selecting this 200 mm bore is appropriate when the 160 mm class (delivering 10053 N at 0.5 MPa) cannot meet your application's push force requirements. The SAI200X125-S provides the necessary power for heavy stamping and large-mass material handling. Because the stroke is 125 mm, side-load risks are moderate, but ensuring proper rod-bearing alignment remains critical to prevent premature seal wear.
As a true ISO 15552 profile cylinder, it is dimensionally interchangeable with other ISO 15552 cylinders, allowing seamless integration into existing foot (LB), flange (FA/FB), or trunnion (TC) mounting setups. Remember that the standard double-acting design relies on continuous air pressure to hold a load; if your application requires position holding during an air-loss event, consider the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variants instead.
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.
