The AirTAC AirTAC SAI200X1050-S ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 1050mm 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 SAI200X1050-S is a double-acting ISO 15552 profile pneumatic cylinder built for heavy-duty actuation. Delivering a push force of 15708 N at 0.5 MPa, it handles massive loads across its 1050 mm stroke. This extended length is a made-to-order non-standard stroke, engineered for applications requiring extreme reach.
This unit includes a magnetic piston for position sensing, compatible with CMSE and DMSE switches fitted into the dual-side sensor grooves. The piston rod utilizes a robust carbon steel construction, and the PT tapered port threading ensures a secure, leak-free pneumatic connection.

Pushes heavy pallets of raw bulk materials or large fabricated components out of automated production bays.
This 200 mm bore cylinder provides immense thrust, so verify your supply pressure can maintain flow for such a large volume. If a slightly smaller force class fits the load, the 160 mm bore offers 10053 N at 0.5 MPa. Because this 1050 mm stroke exceeds the 1000 mm threshold, side load is a primary concern; an unsupported rod of this length will bend under lateral stress. Always pair this actuator with an external guide rail or use a fully guided cylinder to prevent rod-bearing damage.
As a true ISO 15552 profile cylinder, it serves as a drop-in replacement for other ISO 15552 actuators with a 200 mm bore, 1050 mm stroke, G3/4 port, and matching mounting accessories. Note that the adjustable air cushions only decelerate the piston near stroke ends; they do not lock the rod. If the machinery must hold a load vertically without continuous air pressure, specify the SAIL (air-released lock) or BSAI (clamp-lock) variant instead of the standard SAI.
Quick checklist
At 0.5 MPa operating pressure, the SAI200X1050-S provides a push force of 15708 N and a pull force of 15080 N. At 0.7 MPa, the push force increases to 21991 N.
The SAI series is dimensionally interchangeable per the ISO 15552 standard. It serves as a drop-in replacement for any ISO 15552 profile cylinder with a 200 mm bore, 1050 mm stroke, and G3/4 port, but it is not a direct brand-specific part number equivalent.
