The AirTAC AirTAC SAI200X180-S ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 180mm 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 SAI200X180-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty industrial automation. Delivering a substantial 15708 N of push force at 0.5 MPa, this 200 mm bore actuator handles massive loads with precision. The 180 mm stroke provides ample extension for large-scale pressing, lifting, and clamping operations.
Equipped with a magnetic piston (-S), this model seamlessly integrates with CMSE and DMSE sensor switches housed in the dual side grooves of its extruded aluminum barrel. It features a robust carbon steel piston rod and PT tapered port threads, ensuring rugged reliability in the most demanding pneumatic 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.
Generates up to 21991 N of thrust at 0.7 MPa for securely seating large bearings and forming heavy-gauge metal components.
Provides the robust, repeatable impact force required for high-tonnage stamping presses and heavy machinery actuation.
Lifts and positions fully loaded industrial pallets or heavy machinery frames within automated manufacturing cells.
Selecting this 200 mm bore actuator is ideal when applications exceed the 10053 N push force of the 160 mm variant. For operations requiring less than 15708 N, stepping down to the 160 mm bore optimizes space and air consumption. Because the 180 mm stroke is under 300 mm, severe rod-bearing bending is less of a concern here, though external guides are still recommended for offset loads.
This unit provides true ISO 15552 mounting interchangeability, allowing direct replacement of comparable profile cylinders using standard FA, FB, or CA accessories. Note that this standard cylinder lacks a locking mechanism; if the air supply drops, the piston will drift. For suspended loads requiring fail-safe holding, consider the BSAI bidirectional clamp-lock series.
Quick checklist
At an operating pressure of 0.5 MPa, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. At 0.7 MPa, the push force increases to 21991 N.
No, the standard SAI cylinder does not hold position without live air pressure and will drift downward. For suspended vertical loads requiring fail-safe holding, you must use the BSAI clamp-lock variant or an external pilot-operated check valve.
