About the Airtac SAI200 Standard Cylinder SAI200AX120
The AirTAC SAI200X120 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. It provides a substantial push force of 15708 N and a pull force of 15080 N at 0.5 MPa. The 120 mm stroke is ideal for short-travel, high-thrust clamping or lifting operations in large-scale machinery.
This specific configuration features a SUS420J2 stainless steel piston rod for superior corrosion resistance and mechanical durability. It uses PT tapered port threads and lacks a standard magnet, but the extruded aluminum barrel retains dual-side sensor grooves for future position feedback integration.

Where the Airtac SAI200 Standard Cylinder SAI200AX120 Is Used
Heavy Metal Stamping
Provides the intense 15708 N push force required to form thick steel plates and operate large industrial stamping presses over short 120 mm travel distances.
Automotive Assembly Presses
Ideal for driving large robotic welding fixtures and heavy clamping arms where high impact resistance and massive thrust are necessary for structural frame assembly.
Large Mold Handling
Actuates heavy-duty lifting pins and ejector mechanisms in injection molding and metal casting equipment, utilizing the durable SUS420J2 rod to withstand harsh environments.
Is the Airtac SAI200 Standard Cylinder SAI200AX120 the Right Cylinder?
Selecting this 200 mm bore size is appropriate when your application requires moving massive payloads that exceed the 10053 N push force of the 160 mm variant. If your system does not need this extreme thrust, stepping down to the 160 mm bore saves space and air consumption.
Because this is a standard double-acting cylinder, it will not maintain its position or hold a load if air pressure is lost or exhausted. For critical safety applications requiring fail-safe load holding, consider the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variants instead of the standard SAI.
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 SAI200AX120 FAQ
At an operating pressure of 0.5 MPa, the SAI200X200 generates a push force of 15708 N and a pull force of 15080 N. It can reach up to 21991 N push force at 0.7 MPa.
Yes, the SAI200X120 is dimensionally interchangeable per ISO 15552 profile standards. It serves as a drop-in replacement for other ISO 15552 cylinders, utilizing a G3/4 port and matching mounting interface dimensions.
