The AirTAC AirTAC SAI200X90 ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 90mm 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 SAI200X90 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty operations, providing a substantial push force of 15708 N at 0.5 MPa. Its 90 mm stroke is ideal for high-impact pressing, clamping, and short-travel heavy load manipulation.
This specific configuration features a SUS304 stainless steel piston rod (material code B) for superior corrosion resistance and a PT tapered port thread. The extruded aluminum barrel includes integrated sensor grooves on both sides, allowing straightforward mounting of CMSE or DMSE switches when a magnet is specified.

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.
Generates up to 21991 N of push force at 0.7 MPa to drive short-stroke stamping and forming presses for thick gauge materials.
Provides the massive clamping force required to hold large injection molding molds securely shut during high-pressure plastication cycles.
Utilizes its 90 mm stroke and SUS304 stainless steel rod to eject heavy finished parts from machining centers without risking rod corrosion.
Selecting this 200 mm bore cylinder is appropriate when applications demand immense thrust that smaller bores cannot provide, delivering 15708 N at 0.5 MPa compared to 10053 N from a 160 mm bore. Because the 90 mm stroke is relatively short, side-load stress on the rod bearing is minimal, though external guides should still be used for heavy offset loads.
If the machinery requires the piston to maintain its position during a complete loss of air pressure, the standard SAI cylinder will drift and drop the load. For fail-safe holding, integrate the SAIL variant with an air-released lock or the BSAI bidirectional clamp-lock cylinder.
Quick checklist
At an operating pressure of 0.5 MPa, the SAI200X90 generates 15708 N of push force and 15080 N of pull force. At 0.7 MPa, the push force increases to 21991 N.
No, the standard SAI cylinder cannot hold a load without live air pressure and will drift downwards. For vertical load holding, you must use the SAIL variant with an air-released lock or an external rod lock.
