About the Airtac SAI200 Standard Cylinder SAI200AX200S
The AirTAC SAI200X200-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty industrial automation. Delivering a substantial push force of 15708 N at 0.5 MPa, this 200 mm bore unit is built to move massive loads reliably. The 200 mm stroke provides ample extension for large-scale pressing, lifting, or clamping operations.
This configuration features a SUS420J2 stainless steel piston rod (material code A) for superior corrosion resistance in humid or mildly chemically washed environments. Equipped with a magnet (-S), it directly supports CMSE and DMSE sensor switches mounted into the dual-side extruded aluminum barrel grooves. Fluid connections use PT tapered threads, and the assembly includes adjustable air cushions at both ends to decelerate the high kinetic energy of this large-bore actuator.

Where the Airtac SAI200 Standard Cylinder SAI200AX200S Is Used
Heavy Metal Forming
Provides the 15708 N push force at 0.5 MPa required for heavy-duty stamping, pressing, and metal forming operations.
Large Assembly Presses
Ideal for large-scale automotive or industrial assembly lines where massive components must be joined with high force.
Heavy Clamping Fixtures
Secures oversized castings or structural beams during machining, utilizing the SUS420J2 stainless steel rod for durability.
Is the Airtac SAI200 Standard Cylinder SAI200AX200S the Right Cylinder?
Selecting this 200 mm bore actuator makes sense when 160 mm (10053 N at 0.5 MPa) lacks the thrust for your heaviest payloads. Conversely, if your system only requires 10053 N, stepping down to a 160 mm bore saves significant physical envelope and air consumption. The 200 mm stroke is well within standard limits, but always ensure your external guidance can handle the extreme weight of this class.
Because it is a double-acting cylinder, it relies entirely on continuous air pressure to hold position; if air is exhausted, the piston drifts. For applications requiring fail-safe load holding, integrate an external pilot-operated check valve or specify the SAIL (air-released lock) or BSAI (clamp-lock) variant. As a true ISO 15552 profile cylinder, it drops directly into existing mounting interfaces using TC trunnion or LB foot brackets.
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 SAI200AX200S FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides a push force of 15708 N and a pull force of 15080 N. At 0.7 MPa, the push force increases to 21991 N.
Yes, the SAI200X200-S is dimensionally interchangeable per ISO 15552. You can drop it into existing mounting interfaces using standard LB, FA, or TC accessories without modifying the machine frame.
