About the Airtac SAI200 Standard Cylinder SAI200AX45
The AirTAC SAI200X45 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty pneumatic tasks. It generates a substantial 15708 N of push force at 0.5 MPa, extending a short 45 mm stroke to deliver immense impact and clamping power in confined spaces. The extruded aluminum barrel design strictly adheres to standardized mounting interfaces, ensuring seamless integration into large-scale machinery.
This specific configuration features a SUS420J2 stainless steel piston rod (material code A), providing superior resistance to corrosion and mechanical wear in harsh industrial environments. Additionally, the PT (tapered) port threads guarantee a robust, mechanically sealed pneumatic connection that withstands high vibration and pressure fluctuations.

Where the Airtac SAI200 Standard Cylinder SAI200AX45 Is Used
Heavy Metal Stamping
Provides the immense 15708 N push force required to operate heavy-duty stamping presses and form thick-gauge sheet metal components.
Industrial Clamping Jigs
Ideal for securing massive workpieces in CNC machining centers, utilizing its short 45 mm stroke for rapid, high-force actuation.
Injection Mold Ejection
Delivers reliable, high-impact ejection force to release large molded parts from heavy industrial injection molds.
Is the Airtac SAI200 Standard Cylinder SAI200AX45 the Right Cylinder?
Selecting this 200 mm bore model is ideal when an application requires massive thrust that smaller bores cannot achieve, stepping up significantly from the 160 mm bore which offers 10053 N at 0.5 MPa. The 45 mm stroke is optimized for short, high-force movements rather than long transitions. If an application requires the load to remain securely held without continuous air pressure, a standard SAI cylinder will experience drift; in such cases, the SAIL (pneumatic lock) or BSAI (clamp-lock) variant should be specified instead.
Because this is a true ISO 15552 profile cylinder, it serves as a dimensionally interchangeable drop-in replacement for other ISO 15552 cylinders. When ordering, confirm the 200 mm bore, 45 mm stroke, G3/4 port size, PT thread type, and SUS420J2 rod material. Note that sensors are not supported on this unit as the -S magnet option is not specified.
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 SAI200AX45 FAQ
At a 0.5 MPa operating pressure, the SAI200X45 generates 15708 N of push force and 15080 N of pull force. At 0.7 MPa, the push force increases to 21991 N.
Yes, the SAI200X45 is a genuine ISO 15552 profile cylinder, meaning its mounting interface and envelope dimensions are interchangeable with other standard ISO 15552 cylinders of the same bore size.
