About the Airtac SAI200 Standard Cylinder SAI200AX115S
The AirTAC SAI200X115-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty operations requiring immense thrust. It generates 15708 N of push force at just 0.5 MPa and reaches a maximum theoretical output of 3204 kgf at 1.0 MPa. The 115 mm stroke provides targeted, high-force linear motion for substantial payloads.
This specific configuration features a SUS420J2 stainless steel piston rod (material code A) for superior corrosion resistance in humid or chemically exposed environments. It includes a magnet (-S) for direct compatibility with CMSE and DMSE sensor switches, which mount seamlessly into the dual-sided extruded aluminum barrel grooves. The cylinder utilizes PT tapered port threads and adjustable air cushions at both ends to manage kinetic energy.

Where the Airtac SAI200 Standard Cylinder SAI200AX115S Is Used
Heavy Metal Stamping
Provides the 15708 N push force at 0.5 MPa required to form and stamp thick metal sheets in automated fabrication lines.
Injection Mold Ejection
Delivers reliable, high-impact ejection force for large injection molded parts, utilizing its 115 mm stroke and dual air cushions.
Large Press Actuation
Drives heavy industrial presses and clamping fixtures where a 200 mm bore and SUS420J2 rod withstand harsh operational stresses.
Is the Airtac SAI200 Standard Cylinder SAI200AX115S the Right Cylinder?
Selecting this 200 mm bore cylinder is appropriate when applications exceed the 10053 N push force available at 0.5 MPa from the adjacent 160 mm bore size. For lower force requirements, stepping down to the 160 mm bore optimizes space and air consumption. The 115 mm stroke is relatively short for this bore, keeping side-load stress on the rod bearing minimal.
Because it is a double-acting pneumatic actuator, the SAI200X115-S will not hold a load if air pressure drops or the valve centers; the piston will drift. For fail-safe load holding, integrate an external pilot-operated check valve or specify the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variant. As a true ISO 15552 profile cylinder, it serves as a dimensionally interchangeable drop-in replacement for other ISO 15552 cylinders, utilizing standard mounting accessories like FA flanges or 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.
