About the Airtac SAI200 Standard Cylinder SAI200AX280
The AirTAC SAI200X280 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. It provides a substantial push force of 15708 N at 0.5 MPa and a pull force of 15080 N, making it suitable for moving massive loads across a 280 mm stroke. The extruded aluminum barrel design omits tie rods, ensuring a rigid yet streamlined structure.
This specific configuration features a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion and wear resistance in harsh environments. It utilizes PT tapered port threads and lacks a magnet, meaning it is optimized for pure actuation rather than electronic position sensing.

Where the Airtac SAI200 Standard Cylinder SAI200AX280 Is Used
Heavy Stamping
Provides the immense 15708 N push force required to actuate large metal forming and stamping presses.
Injection Molding Extraction
Drives heavy-duty robotic arms to pull large molded parts from industrial injection molding machines.
Large Valve Actuation
Reliably operates oversized industrial process valves and heavy fluid control mechanisms in manufacturing plants.
Is the Airtac SAI200 Standard Cylinder SAI200AX280 the Right Cylinder?
Selecting this 200 mm bore cylinder is appropriate when applications require extremely high thrust that smaller bores cannot provide, such as stepping up from a 160 mm bore that yields 10053 N at 0.5 MPa. Because the 280 mm stroke is below the 300 mm threshold, side-load stress on the rod bearing is moderate, though external guides are still recommended for optimal longevity if heavy off-center loads are present.
As a standard double-acting cylinder, the SAI200X280 relies on live air pressure to hold its position; if air is exhausted or the valve is centered, the piston will drift. For tasks that require fail-safe load holding without constant pressure, consider the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variants. This model serves as a dimensionally interchangeable drop-in replacement for any ISO 15552 cylinder, utilizing a G3/4 port and supporting standard mounting accessories like TC trunnion or FA flange.
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.
