About the Airtac SAI200 Standard Cylinder SAI200AX150
The AirTAC SAI200X150 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty industrial automation. Featuring a 200mm bore and 150mm stroke, it generates a substantial push force of 15708 N and a pull force of 15080 N at 0.5 MPa. This model is built with a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance in demanding environments.
As a genuine ISO 15552 standardized unit, this extruded aluminum profile cylinder ensures seamless dimensional interchangeability for global machine upgrades. It utilizes PT tapered port threads and includes adjustable air cushions at both ends to absorb kinetic energy. For applications requiring position holding without continuous air pressure, consider integrating the SAIL or BSAI locking variants.

Where the Airtac SAI200 Standard Cylinder SAI200AX150 Is Used
Heavy Metal Forming
Provides the robust 15708 N push force required for pressing, stamping, and bending thick metal components in primary manufacturing lines.
Large Mold Clamping
Secures oversized injection molds or heavy casting dies with high axial stability, utilizing its 200mm bore for maximum clamping pressure.
Industrial Press Brakes
Drives heavy-duty press brake assemblies where slow, controlled movement and massive kinetic energy absorption are critical for shaping plate steel.
Is the Airtac SAI200 Standard Cylinder SAI200AX150 the Right Cylinder?
Selecting the SAI200X150 is ideal when massive thrust is required, as stepping down to a 160mm bore reduces the 0.5 MPa push force to 10053 N. If even greater force is necessary, note that 200mm is the largest standard bore in this series. This cylinder operates at a controlled speed range of 30-500 mm/s due to its large piston mass.
Although the 150mm stroke is relatively short for this bore size, always verify rod bearing loads in heavy push applications. Because standard double-acting cylinders exhaust and drift when air pressure is removed, any load requiring static holding must use an external pilot-operated check valve or the AirTAC SAIL pneumatic lock variant. This unit is fully interchangeable with other ISO 15552 cylinders using standard FA or FB 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 SAI200AX150 FAQ
At 0.5 MPa operating pressure, this 200mm bore cylinder provides a push force of 15708 N and a pull force of 15080 N. If pressure is increased to 0.7 MPa, the push force reaches 21991 N.
Yes, the SAI200X150 is a true ISO 15552 profile cylinder, making it dimensionally interchangeable with other standard ISO 15552 cylinders. You can use existing mounting accessories like TC trunnions or CA clevises for a direct drop-in replacement.
