About the Airtac SAI200 Standard Cylinder SAI200AX200
The AirTAC SAI200X200 is a heavy-duty, double-acting ISO 15552 profile cylinder engineered for immense thrust requirements. Generating 15708 N of push force at just 0.5 MPa and reaching a maximum theoretical output of 3204 kgf at 1.0 MPa, this 200 mm bore unit effortlessly moves massive loads. The 200 mm stroke provides substantial extension for large-scale pressing, lifting, and clamping operations.
This model is equipped with a SUS420J2 stainless steel piston rod (material code A) for superior corrosion and wear resistance in harsh environments. It features PT tapered port threads and utilizes an extruded aluminum barrel without tie-rods, incorporating dual sensor grooves for straightforward position detection. For applications requiring position holding without continuous air pressure, consider the SAIL or BSAI locking variants.

Where the Airtac SAI200 Standard Cylinder SAI200AX200 Is Used
Heavy Metal Forming
Provides the robust 15708 N push force required for heavy-duty stamping, bending, and metal forming operations at 0.5 MPa.
Industrial Pressing
Ideal for large industrial presses requiring massive, steady pressure over a 200 mm stroke, utilizing adjustable cushions to absorb high kinetic energy.
Large Assembly Jigs
Drives heavy-duty assembly fixtures and jigs where the SUS420J2 stainless steel rod offers reliable performance in demanding industrial environments.
Is the Airtac SAI200 Standard Cylinder SAI200AX200 the Right Cylinder?
Selecting the SAI200X200 is appropriate when application thrust demands exceed the 10053 N push force (at 0.5 MPa) of the neighboring 160 mm bore. Operating at a controlled speed range of 30-500 mm/s, this cylinder manages heavy inertial loads effectively via its 50 mm adjustable air cushions at both ends. Because the 200 mm stroke is relatively short for this massive bore, side-load stress on the rod bearing is minimized compared to longer strokes, but proper mounting alignment remains critical.
As a true ISO 15552 standard cylinder, its envelope and mounting dimensions allow direct drop-in replacement for other ISO 15552 profile cylinders. Ensure your system specifies a 200 mm bore, 200 mm stroke, G3/4 PT ports, and compatible mounting accessories like the TC trunnion or LB foot bracket. Note that a standard SAI does not hold position upon air loss; use an external rod lock for fail-safe load holding.
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.
