The AirTAC AirTAC SAI200X550-S ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 550mm 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 SAI200X550-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty linear motion. Delivering a robust 15708 N of push force at 0.5 MPa, this 200mm bore actuator handles substantial payloads with ease. The 550mm stroke provides the extended travel distance required for large-scale material handling and forming operations. As a genuine AirTAC component, it guarantees reliable performance in demanding industrial environments.
This model includes a standard magnet (-S) for direct compatibility with CMSE and DMSE reed switches, fitting smoothly into the dual sensor grooves machined into the extruded aluminum barrel. The piston rod utilizes high-strength carbon steel for structural integrity under high thrust loads, and the tapered PT port threads ensure a tight, leak-free pneumatic connection. Adjustable air cushions at both ends protect the end caps from impact damage during high-speed cycles.

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 push force at 0.7 MPa necessary to drive large stamping and forming dies through heavy-gauge metal sheets.
Leverages the 550mm stroke to push heavy pallets or bulk material bins across wide transfer lines without requiring multi-stage cylinders.
Applies consistent clamping pressure on oversized automotive or structural components during robotic welding and fastening cycles.
Selecting this 200mm bore actuator is appropriate when systems require maximum thrust, specifically the 15708 N generated at 0.5 MPa or 21991 N at 0.7 MPa. If a project does not require this level of force, stepping down to a 160mm bore reduces the push force to 10053 N while saving valuable mounting space. Because this unit features a 550mm stroke, the extended unsupported piston rod is susceptible to bending under side loads; utilizing an external guide rail or a guided cylinder module is strongly recommended to prevent premature rod-bearing wear.
This profile cylinder offers drop-in dimensional interchangeability with other ISO 15552 actuators, simplifying machinery upgrades and replacements. The pneumatic connection uses a G3/4 port. Note that the adjustable cushions only decelerate the piston at stroke ends; if the application must hold a vertical load safely without constant air pressure, integrate the SAIL locking variant or an external pilot-operated check valve.
Quick checklist
This 200mm bore cylinder generates 15708 N of push force and 15080 N of pull force at 0.5 MPa. When operating at 0.7 MPa, the push force increases to 21991 N.
Yes, the SAI200X550-S is a genuine ISO 15552 profile cylinder, making its mounting interface dimensionally interchangeable with other standard ISO 15552 actuators of the same bore size.
