The AirTAC AirTAC SAI200X550 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 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty operations, delivering a substantial push force of 15708 N at 0.5 MPa. Its extruded aluminum barrel omits tie-rods, presenting a clean profile that drops directly into standardized ISO 15552 mounting interfaces. This specific 550 mm stroke configuration is ideal for substantial linear actuation tasks requiring both reach and extreme power.
Built for longevity in demanding environments, this unit features a SUS304 stainless steel rod (material code B) for superior corrosion resistance. The fluid porting utilizes PT tapered threads to ensure a robust, leak-free pneumatic connection. For applications requiring multi-position stopping or bidirectional clamping, this base model can be cross-referenced with the SAID or BSAI variant families.

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 to actuate large stamping presses and heavy-gauge metal forming machinery over a 550 mm travel distance.
Drives large-body welding fixtures and heavy component positioning systems where a robust 200 mm bore and extended 550 mm stroke are strictly necessary.
Shifts substantial injection molding tooling or heavy cast components, utilizing the 3204 kgf theoretical max force to move loads reliably through long cycles.
Selecting this 200 mm bore cylinder is appropriate when your application demands maximum thrust, specifically 15708 N of push force at 0.5 MPa or up to 3204 kgf at 1.0 MPa. If the load requirement drops, stepping down to a 160 mm bore reduces the push force to 10053 N while saving valuable mounting space.
Because this model features a 550 mm stroke, the extended rod is highly susceptible to bending under side loads. To prevent premature rod-bearing failure, utilize an external guide rail or opt for a guided cylinder. Furthermore, a standard SAI cannot hold a load safely upon air loss; for fail-safe position holding, integrate an external pilot-operated check valve or specify the SAIL air-released lock variant. Ensure your mounting setup accommodates the G3/4 porting and pair it with FA/FB flanges or LB foot brackets as needed.
Quick checklist
At a standard operating pressure of 0.5 MPa, the SAI200X550 generates 15708 N of push force and 15080 N of pull force. At 0.7 MPa, the push force increases to 21991 N.
Yes, the SAI200X550 is dimensionally interchangeable per ISO 15552 and serves as a drop-in replacement for other ISO 15552 profile cylinders, provided the 200 mm bore, 550 mm stroke, and G3/4 port dimensions match your existing fixture.
