Airtac SAI200 Standard Cylinder SAI200AX145
The AirTAC Airtac SAI200 Standard Cylinder SAI200AX145 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 145mm stroke, G3/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAI200 Standard Cylinder SAI200AX145
The AirTAC SAI200X145 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty industrial automation. Operating at 0.5 MPa, it generates a substantial push force of 15708 N and a pull force of 15080 N. This 145 mm stroke length is optimal for high-thrust pressing, heavy clamping, and large-mold handling tasks.
Beyond the standardized mounting interface, this specific configuration features a SUS420J2 stainless steel piston rod (material code A) for superior corrosion and wear resistance in harsh environments. Fluid supply connects via PT tapered ports, and the extruded aluminum barrel includes dual sensor grooves. For applications requiring position holding upon air loss, consider the SAIL variant rather than relying on the standard adjustable air cushions.

Where the Airtac SAI200 Standard Cylinder SAI200AX145 Is Used
Heavy Metal Stamping
Provides the 15708 N push force required to operate large mechanical presses and form thick sheet metal components reliably.
Injection Mold Handling
Moves large injection molding tools and heavy industrial dies into position with precise 145 mm stroke control.
Large Assembly Pressing
Delivers consistent high-thrust force for seating heavy-duty bearings, gear assemblies, and large automotive sub-components.
Is the Airtac SAI200 Standard Cylinder SAI200AX145 the Right Cylinder?
Selecting this 200 mm bore cylinder is appropriate when forces exceed the 10053 N push capacity of the 160 mm bore at 0.5 MPa. Because the 145 mm stroke is below the 300 mm threshold, rod-bearing bending from side loads is minimal, though external guides remain recommended for heavy payloads. The operational speed range is 30-500 mm/s.
As a true ISO 15552 profile cylinder, it serves as a direct dimensional drop-in replacement for other ISO 15552 cylinders. Ensure your setup matches the G3/4 port size, M36x2 rod thread, and 50 mm cushion length. Mounting accessories include LB foot brackets, FA/FB flanges, and TC trunnion 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 SAI200AX145 FAQ
At an operating pressure of 0.5 MPa, the SAI200X145 cylinder delivers 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 is a genuine ISO 15552 profile cylinder, making its mounting dimensions fully interchangeable with other standard ISO 15552 cylinders of the same bore size.
