About the Airtac SAI200 Standard Cylinder SAI200AX325
The AirTAC SAI200X325 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a robust 15708 N push force at 0.5 MPa, this 200 mm bore unit handles substantial loads with ease. The 325 mm stroke provides the extended travel needed for large-scale clamping, pressing, and material handling tasks.
This configuration features a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance in demanding environments. Fluid ports utilize a PT tapered thread type. Because no magnet is specified, position sensing via CMSE or DMSE switches is not enabled on the dual sensor grooves. For applications requiring position holding upon air loss, consider the SAIL or BSAI variants.

Where the Airtac SAI200 Standard Cylinder SAI200AX325 Is Used
Heavy-Duty Pressing
Provides the 15708 N force at 0.5 MPa required for assembling large components and forming heavy-gauge materials.
Industrial Stamping
The 325 mm stroke accommodates deep-draw stamping operations, utilizing the SUS420J2 rod for reliable performance.
Bulk Material Diversion
Drives large-scale diverter gates on heavy conveyors, moving bulk aggregates with sustained kinetic output.
Is the Airtac SAI200 Standard Cylinder SAI200AX325 the Right Cylinder?
Selecting this 200 mm bore cylinder is ideal when 15708 N of push force at 0.5 MPa is required. If your application needs less force, stepping down to the 160 mm bore provides 10053 N at 0.5 MPa, optimizing space and air consumption. The 325 mm stroke falls within the standard maximum of 1500 mm but requires careful attention to side loads.
Long unsupported strokes increase the risk of rod-bearing bending under lateral forces. Implement external guide rails or select a guided cylinder to manage side loads effectively. This SAI unit serves as a drop-in replacement for other ISO 15552 profile cylinders, matching the standardized mounting interface, PT porting, and accessory footprint. Mounting options include LB, FA, TC, and CA styles.
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 SAI200AX325 FAQ
