The AirTAC AirTAC SAI200X950 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 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty positioning. Delivering a substantial 21991 N of push force at 0.7 MPa across its 950 mm span, it is tailored for massive load manipulation. This specific configuration features a SUS420J2 stainless steel rod (material code A) paired with PT tapered port threading.
Because the standard stroke ceiling for this bore is 1500 mm, this 950 mm unit remains within the conventional manufacturing envelope. The extruded aluminum barrel incorporates dual-sided sensor grooves, enabling direct mounting of CMSE or DMSE switches when a magnet is specified, ensuring precise end-of-stroke detection in demanding industrial environments.

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 21991 N push force required to actuate large press beds and heavy-gauge metal forming dies over a long 950 mm travel distance.
Drives massive structural components into alignment on automotive or heavy machinery welding lines, utilizing the full 950 mm extension for wide-span parts.
Shifts loaded industrial pallets or heavy machinery chassis across automated conveyor networks, relying on the robust 200 mm profile barrel to handle extreme weights.
Selecting this 200 mm bore unit implies your application requires the highest force tier available in the SAI range, pushing 21991 N at 0.7 MPa. If a slightly lower thrust is acceptable, stepping down to the 160 mm bore yields 14074 N at the same pressure, which may reduce air consumption and physical footprint.
At a 950 mm stroke, the extended rod is highly susceptible to bending under side loads. To prevent premature rod-bearing wear and piston scoring, utilize an external guide rail or select a guided cylinder module. Furthermore, this standard profile cylinder cannot hold a load if air pressure drops; integrate an external pilot-operated check valve or specify a SAIL variant for fail-safe mechanical locking. Replacement mounting requires matching the ISO 15552 interface, 200 mm bore, 950 mm stroke, G3/4 port, and appropriate accessories like TC trunnion or FA flange.
Quick checklist
The SAI200X950 generates a push force of 21991 N and a pull force of 15080 N when operated at 0.7 MPa. At the maximum operating pressure of 1.0 MPa, the theoretical push force reaches 3204 kgf.
Yes, the SAI200X950 is dimensionally interchangeable with other ISO 15552 profile cylinders. Ensure your system matches the 200 mm bore, 950 mm stroke, G3/4 port, and desired mounting accessories like the TC trunnion or LB foot.
