The AirTAC AirTAC SAI200X85-S ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 85mm 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 SAI200X85-S is a double-acting ISO 15552 profile cylinder engineered for extreme thrust requirements, delivering 15708 N of push force at 0.5 MPa. Its 85 mm stroke is a made-to-order length, providing a short, rigid extension for high-force clamping or pressing tasks within confined machinery.
This configuration includes a SUS304 stainless steel rod for superior corrosion resistance and a magnetic piston (-S) compatible with CMSE and DMSE sensor switches. The extruded aluminum barrel features dual sensor grooves, and the body utilizes PT tapered port threads to ensure a robust, leak-free pneumatic connection.

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 immense 15708 N push force required to form thick metal sheets and operate heavy-duty mechanical stamping dies.
Acts as a core puller or heavy mold actuator, utilizing its SUS304 rod to withstand abrasive environments and high clamping forces.
Delivers reliable, short-stroke thrust for pressing large bearings or heavy machinery components into precise alignment.
Selecting this 200 mm bore is ideal when 160 mm (9425 N pull at 0.5 MPa) lacks the necessary force for heavy stamping or lifting. Because the 85 mm stroke is non-standard, expect a made-to-order lead time. For applications needing secure load holding during air loss, select the SAIL or BSAI variant instead of relying on the standard adjustable air cushions, which only decelerate the piston near stroke end.
To match this cylinder for a drop-in replacement, ensure the target unit shares the ISO 15552 mounting interface, 200 mm bore, 85 mm stroke, G3/4 port, and compatible mounting accessories like FA or FB flanges. The integrated magnet allows for precise end-of-stroke detection.
Quick checklist
At a 0.5 MPa operating pressure, this 200 mm bore cylinder generates 15708 N of push force and 15080 N of pull force. It achieves a maximum theoretical force of 3204 kgf at 1.0 MPa.
Yes, the SAI200X85-S is dimensionally interchangeable per ISO 15552. You can drop-in replace any cylinder matching the 200 mm bore, 85 mm stroke, G3/4 port, and standard mounting interface.
