About the Airtac SAI200 Standard Cylinder SAI200AX400
The AirTAC SAI200X400 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a robust push force of 15708 N at 0.5 MPa, this 200mm bore unit is built to move substantial loads over its 400mm stroke.
Reflecting the exact configuration requested, this model features a SUS420J2 stainless steel piston rod (code A) for superior corrosion resistance and utilizes PT tapered port threads. The extruded aluminum barrel omits tie-rods and includes sensor grooves on both sides for straightforward position detection.

Where the Airtac SAI200 Standard Cylinder SAI200AX400 Is Used
Heavy Metal Stamping
Provides the immense 15708 N push force required to actuate large mechanical stamping presses and heavy-duty forming dies.
Automotive Assembly Jigs
Drives large-scale positioning fixtures and heavy component handling rigs on automotive production lines.
Bulk Material Handling
Controls heavy diverter gates and large pneumatic sorting flaps in high-capacity mining or aggregate conveyors.
Is the Airtac SAI200 Standard Cylinder SAI200AX400 the Right Cylinder?
With a massive 15708 N push force at 0.5 MPa, this 200mm bore is the largest standard SAI size. If your application requires less force, stepping down to a 160mm bore yields 10053 N at 0.5 MPa, which may reduce air consumption and overall footprint.
Because the 400mm stroke presents a long unsupported rod length, side loads can cause severe bending stress on the rod bearing. Implement an external guide rail or select a guided cylinder to prevent premature wear. Note that standard SAI cylinders will drift if air pressure is lost; use the SAIL locking variant if the load must be held safely without live pressure. Being dimensionally interchangeable per ISO 15552, it serves as a drop-in replacement for other ISO 15552 profile cylinders, utilizing a G3/4 port and compatible TC trunnion or LB foot 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 SAI200AX400 FAQ
The SAI200X400 generates a push force of 15708 N and a pull force of 15080 N when operated at 0.5 MPa.
Yes, for a 400mm stroke, an external guide rail or guided cylinder is highly recommended to manage side-load bending and protect the rod bearing.
