The AirTAC AirTAC SAI200X475-S 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-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty motion tasks. Operating at 0.5 MPa, it generates a substantial push force of 15708 N and a pull force of 15080 N. The 475 mm stroke provides ample travel for large-scale positioning. This unit is a genuine AirTAC component built to exacting dimensional standards.
Configured specifically for rugged environments, this model features a SUS304 stainless steel rod (option B) for superior corrosion resistance. It includes a magnet (-S) for seamless integration with CMSE and DMSE sensor switches housed in the dual-side barrel grooves. Fluid ports utilize a PT tapered thread type, ensuring robust sealing for high-flow pneumatic demands.

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 15708 N of thrust at 0.5 MPa required to actuate large mechanical presses and form thick gauge metal components securely.
Utilizes the 475 mm stroke and SUS304 rod to shift heavy injection molds or tooling blocks into and out of heavy machinery safely.
Leverages the dual-side sensor grooves and CMSE switches to reliably trigger heavy-duty diverter arms on high-capacity aggregate or mining conveyors.
Selecting this 200 mm bore cylinder is ideal when applications require moving heavy payloads within the 15080 N to 15708 N range at 0.5 MPa. If a project demands less force, stepping down to the 160 mm bore yields 10053 N of push force, whereas staying at 200 mm is necessary for maximum thrust. The 475 mm stroke falls within the standard limit of 1500 mm, but its extended length requires careful mounting to prevent rod-bearing bending under side loads. For setups involving heavy off-center loads, utilize external guide rails or transition to a guided cylinder to preserve bearing life.
This model is dimensionally interchangeable per ISO 15552, serving as a direct drop-in replacement for other ISO 15552 profile cylinders. To complete your setup, pair it with appropriate mounting accessories like TC trunnion or CA clevis brackets, and ensure your pneumatic supply is filtered to 40 um. Note that the standard SAI does not hold its position when air pressure is lost; if your workflow requires dead-air load holding, consider the BSAI clamp-lock variant or an external rod lock.
Quick checklist
At an operating pressure of 0.5 MPa, the SAI200X475-S generates a push force of 15708 N and a pull force of 15080 N. The maximum theoretical force at 1.0 MPa is 3204 kgf.
Yes, the SAI200X475-S is a genuine AirTac component built to the ISO 15552 profile standard, making it dimensionally interchangeable with other ISO 15552 cylinders. It uses a G3/4 port and an M36x2 rod thread.
