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 heavy-duty double-acting profile cylinder built to ISO 15552 dimensional standards. It features a robust 200mm bore and a 950mm stroke, generating 15708 N of push force at 0.5 MPa and reaching 21991 N at 0.7 MPa. This specific 950mm stroke is a made-to-order non-standard length, optimized for applications requiring massive reach and high thrust.
Equipped with a magnet for proximity sensing, this model seamlessly integrates CMSE and DMSE switches via the dual sensor grooves on the extruded aluminum barrel. The piston rod utilizes a carbon steel construction for high tensile durability under heavy loads, and the fluid ports feature a PT tapered thread design for secure, leak-free pneumatic connections.

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 21991 N force at 0.7 MPa required for large metal forming and heavy stamping presses over a 950mm travel distance.
Handles large chassis manipulation and heavy component lifting on automotive production lines where long reach and high thrust are mandatory.
Actuates large-scale diverter gates and heavy load-indexing mechanisms in bulk material conveying systems.
Because this 950mm stroke exceeds the standard 1500mm maximum for the 200mm bore, it is manufactured as a special made-to-order configuration. When evaluating force requirements, stepping down to a 160mm bore yields 10053 N at 0.5 MPa, which may be insufficient for heavy-duty pressing, whereas the 200mm bore provides the necessary 15708 N baseline. For a stroke of this length, side load is a critical concern; the extended rod is highly susceptible to bending under lateral stress. Implementing an external guide rail or utilizing a guided cylinder is strongly recommended to prevent rod bearing wear and premature failure.
This cylinder uses a G3/4 port and an M36x2 rod thread. It is dimensionally interchangeable with other ISO 15552 profile cylinders, allowing for a direct drop-in replacement using standard FA/FB flanges or TC trunnion mounts. Note that the adjustable air cushions at both ends decelerate the massive piston mass near stroke end but do not hold the load; if static holding is required during pressure loss, specify the SAIL (air-released lock) or BSAI (clamp-lock) variant instead.
Quick checklist
The SAI200X950-S generates 15708 N of push force and 15080 N of pull force at 0.5 MPa. At 0.7 MPa, the push force increases to 21991 N.
Yes, the SAI200X950-S is dimensionally interchangeable per ISO 15552 profile cylinder standards. It can serve as a drop-in replacement for other ISO 15552 cylinders using standard mounting accessories.
