About the Airtac SAI200 Standard Cylinder SAI200AX35
The AirTAC SAI200X35 is a heavy-duty double-acting profile cylinder built to exact ISO 15552 dimensional standards, ensuring seamless drop-in compatibility with other global ISO 15552 mounting interfaces. Operating within a 0.15-1.0 MPa pressure range, it generates a substantial 15708 N push force at 0.5 MPa, making it well-suited for short-stroke pressing and heavy clamping operations.
This specific configuration features a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance compared to standard carbon steel. The extruded aluminum barrel includes sensor grooves on both sides, allowing for direct CMSE or DMSE switch mounting if a magnet is added later. The standard adjustable air cushions at both ends effectively decelerate the massive internal moving mass.

Where the Airtac SAI200 Standard Cylinder SAI200AX35 Is Used
Heavy Metal Stamping
Provides the intense 15708 N push force required to form and stamp thick-gauge metal components in automated fabrication lines.
Industrial Pressing
Executes short-stroke, high-tonnage pressing operations for assembling bearings or seating heavy machinery components securely.
Massive Clamping Jigs
Holds large structural steel beams or heavy castings firmly in place during welding, machining, or drilling processes.
Is the Airtac SAI200 Standard Cylinder SAI200AX35 the Right Cylinder?
Selecting this 200 mm bore model is ideal when an application requires massive force in a very compact stroke envelope, as the 35 mm travel minimizes overall length while delivering up to 3204 kgf of theoretical maximum thrust. If a project requires slightly less force and a smaller physical footprint, stepping down to the 160 mm bore yields 10053 N at 0.5 MPa. Because this stroke is well under 300 mm, side-load stress on the rod bearing is inherently minimized.
For drop-in replacements, verify the 200 mm bore dimensions, 35 mm stroke, G3/4 port size, and PT threaded connections. Mounting can be configured using FA or FB flanges, LB foot brackets, or TC trunnion styles. Note that a standard SAI cylinder relies on continuous air pressure to maintain its position; if pneumatic supply is lost, the piston will drift. For applications requiring positive load holding upon air exhaustion, specify the SAIL variant with an air-released lock or the BSAI clamp-lock version.
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 SAI200AX35 FAQ
At a standard operating pressure of 0.5 MPa, this 200 mm bore cylinder provides a push force of 15708 N and a pull force of 15080 N. At the maximum rated pressure of 1.0 MPa, the theoretical push force reaches 3204 kgf.
No, the standard SAI200X35 relies on live air pressure and will drift if the supply is exhausted or a valve is centered. The adjustable air cushions only decelerate the piston at stroke end and do not act as a brake. For fail-safe load holding, use the SAIL variant or an external rod lock.
