The AirTAC AirTAC SAI200X850 ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 850mm 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.
The AirTAC SAI200X850 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. It provides a substantial push force of 15708 N and a pull force of 15080 N at 0.5 MPa. This 850 mm stroke excels in moving massive loads across long linear distances.
Configured with a SUS304 stainless steel rod for superior corrosion resistance, this model uses PT tapered port threads. Because it lacks a magnet, position sensing requires external switches. For operations needing secure load holding during air loss, the BSAI bidirectional clamp-lock variant is recommended.

Related SAI-family variants: SAID (double rod), SAIJ (adjustable stroke), SAIL (with lock), SAIF (with valve), BSAI (enclasp / clamp-lock), and SAI-S with built-in magnet. Rod material: carbon steel (blank) / SUS420J2 (A) / SUS304 (B); seals: TPU (blank) / Viton H / NBR N.
Provides the robust 15708 N thrust required to actuate large forming presses and heavy industrial machinery over the 850 mm extension.
Drives heavy structural components or automotive chassis frames along extended assembly lines where high pull force is equally critical.
Shifts heavy pallets or bulk material containers, utilizing the 850 mm stroke to clear wide operational zones safely.
Select this 200 mm bore when 160 mm (10053 N at 0.5 MPa) lacks the thrust for high-inertia loads. The 850 mm stroke demands careful side-load management; long unsupported rods bend easily under lateral forces. Implement external guide rails or a guided cylinder to protect the rod bearing from premature wear.
As a true ISO 15552 profile cylinder, it drops directly into existing mounting footprints. Match your replacement by verifying the 200 mm bore, 850 mm stroke, G3/4 port, and required mounting accessory like TC trunnion. Note that standard air cushions only decelerate the piston at end-of-stroke and will not hold a load without live pressure.
Quick checklist
At an operating pressure of 0.5 MPa, the SAI200X850 generates 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 SAI200X850 is dimensionally interchangeable per ISO 15552. You can drop it into existing setups by matching the 200 mm bore, 850 mm stroke, G3/4 port, and mounting accessories, without claiming brand equivalence.
