The AirTAC AirTAC SAI200X950-S ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 950mm 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 SAI200X950-S is a double-acting ISO 15552 profile cylinder built for heavy-duty positioning. It delivers a robust push thrust of 15708 N at 0.5 MPa, scaling up to 28274 N at 0.9 MPa. This 950 mm stroke variant is tailored for applications requiring extensive linear travel across large-scale machinery.
Equipped with a magnet for position sensing, it seamlessly integrates with CMSE and DMSE switches. The piston rod is crafted from SUS420J2 stainless steel, offering superior corrosion resistance, and utilizes PT tapered port threads to ensure a 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.
Drives massive press beds and heavy metal forming stations requiring 950 mm of travel and up to 28274 N of output force at 0.9 MPa.
Actuates large-scale automotive body framing jigs, utilizing the SUS420J2 stainless steel rod to withstand harsh plant environments.
Operates heavy-duty bulk material diverters and large overhead conveyor routing gates where a 200 mm bore is essential.
This 200 mm bore provides maximum force, so step down to a 160 mm bore (10053 N at 0.5 MPa) if your load requires less energy. Because the 950 mm stroke creates a long unsupported rod, side loads will cause severe rod-bearing bending; always pair this cylinder with an external guide rail or use a fully guided cylinder to prevent premature wear.
For drop-in compatibility, match the 200 mm bore, 950 mm stroke, PT port thread, and the required mounting accessory (such as a TC trunnion or CA clevis). If a machine loses air pressure, this standard cylinder cannot hold its load and will drift; use a BSAI clamp-lock variant if static holding is mandatory.
Quick checklist
At 0.5 MPa, the push force is 15708 N and the pull force is 15080 N. When operating at 0.9 MPa, the push force increases to 28274 N.
No, the 950 mm stroke creates a long unsupported rod that will bend under side loads. You must use an external guide rail or a guided cylinder to protect the rod bearing.
