The AirTAC AirTAC SAI200X475 ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 475mm 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 SAI200X475 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. It provides a robust push force of 15708 N at 0.5 MPa and a theoretical maximum of 3204 kgf at 1.0 MPa. The 475 mm stroke handles substantial linear travel requirements in large-scale machinery.
This specific configuration features a corrosion-resistant SUS304 stainless steel rod and PT tapered port threads. The extruded aluminum barrel includes integrated sensor grooves on both sides, allowing direct mounting of CMSE or DMSE switches if a magnet is added later.

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 thrust needed for large-scale press operations and metalworking fixtures.
Actuates heavy-duty lifting platforms and positions large chassis components on the line.
Drives heavy diverter gates and pusher mechanisms in high-capacity logistics centers.
Selecting this 200 mm bore model is appropriate when applications exceed the 10053 N push force of the 160 mm variant at 0.5 MPa. Because the 475 mm stroke creates an extended rod, external guide rails or a guided cylinder carriage are strongly recommended to prevent rod-bearing bending under side loads.
This unit uses a G3/4 port and an M36x2 rod thread. It is dimensionally interchangeable per ISO 15552, serving as a drop-in replacement for other ISO 15552 profile cylinders. Note that the standard adjustable air cushions only decelerate the piston near end-of-stroke; they do not hold loads. For position holding without air pressure, specify the SAIL or BSAI variant.
Quick checklist
At an operating pressure of 0.5 MPa, this 200 mm bore cylinder 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 SAI200X475 is a genuine ISO 15552 profile cylinder. It is dimensionally interchangeable with other ISO 15552 cylinders, allowing a direct drop-in replacement using standard mounting accessories like TC trunnions or LB foot brackets.
