About the Airtac SAI200 Standard Cylinder SAI200AX20S
The AirTAC SAI200X20-S is a double-acting ISO 15552 profile cylinder engineered for immense thrust, delivering 15708 N push force at just 0.5 MPa. Its 20 mm stroke is optimal for high-force clamping, riveting, or pressing operations requiring minimal travel. This non-standard stroke configuration is manufactured to order for specialized short-stroke machinery.
Equipped with a -S magnet, the barrel integrates dual sensor grooves for direct CMSE or DMSE switch mounting. This specific unit features a SUS420J2 stainless steel rod for enhanced corrosion resistance and utilizes PT tapered port threads. The extruded aluminum barrel design omits tie-rods, providing a clean exterior that complies strictly with ISO 15552 mounting dimensions.

Where the Airtac SAI200 Standard Cylinder SAI200AX20S Is Used
Heavy-Duty Pressing
Generates up to 21991 N at 0.7 MPa for short-stroke metal stamping, riveting, and bearing seating in automated fabrication lines.
Industrial Clamping
Provides massive holding force for securing large molds or heavy structural components during machining and welding processes.
Plastic Injection Molding
Acts as a high-force ejector or core-pull mechanism, utilizing the 20 mm stroke for rapid, short-travel extraction of molded parts.
Is the Airtac SAI200 Standard Cylinder SAI200AX20S the Right Cylinder?
Selecting this 200 mm bore cylinder is appropriate when application force requirements exceed the 10053 N (at 0.5 MPa) capacity of the 160 mm bore variant. The 20 mm stroke is highly specialized; if standard short strokes are needed, consider the 25 mm standard option, but ensure the 20 mm travel perfectly matches your mechanical stopping distance.
Because the stroke is well under 300 mm, rod-bearing bending from side loads is minimal compared to longer units, though external guides are still recommended for heavy pressing. This cylinder does not hold position upon loss of air pressure; for dead-load holding, integrate an external pilot-operated check valve or specify the SAIL lock variant. Replacement mounting interfaces must match the 200 mm bore ISO 15552 footprint, G3/4 PT ports, and appropriate TC trunnion or FA flange accessories.
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 SAI200AX20S FAQ
At 0.5 MPa, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. If operating pressure increases to 0.7 MPa, the push force reaches 21991 N.
Yes, the SAI200X20-S is dimensionally interchangeable with other ISO 15552 profile cylinders. You can drop it into existing setups utilizing the same 200 mm bore mounting dimensions and G3/4 port locations.
