The AirTAC AirTAC SAI200X275-S ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 275mm 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 SAI200X275-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a formidable 15708 N of push force at 0.5 MPa, this 200mm bore actuator handles massive payloads with precision. The 275mm stroke provides substantial travel for large-scale indexing, pressing, and material handling tasks.
Equipped with a magnet for CMSE and DMSE sensor switches, this model enables seamless position feedback across both barrel grooves. It features a robust carbon steel piston rod and PT tapered port threads, ensuring durable, leak-free operation in the most demanding industrial environments.

Drives large stamping presses and forming dies requiring immense, steady push force over long strokes.
Actuates heavy-duty clamping and positioning fixtures for chassis components on high-throughput lines.
Shifts heavy pallets or bulk material diverters on robust conveyor systems handling substantial weights.
Select this 200mm bore actuator when your application requires extreme thrust that smaller bores cannot provide, such as stepping up from a 160mm bore which yields 10053 N at 0.5 MPa. For lower force requirements at 0.5 MPa, consider dropping to the 125mm bore (6136 N) to optimize air consumption and footprint.
Since this 275mm stroke falls below the 300mm threshold, standard side-load risks are moderate, but ensuring proper rod bearing alignment remains critical for longevity. If the machinery must hold a load statically without continuous air pressure, note that the standard adjustable air cushions only decelerate the piston at stroke end and do not act as a lock; for fail-safe holding, integrate the SAIL locking variant or an external pilot-operated check valve. As a true ISO 15552 profile cylinder, it offers drop-in dimensional interchangeability with other ISO 15552 actuators, utilizing G3/4 ports and compatible FA or LB mounting accessories.
Quick checklist
At a 0.5 MPa operating pressure, this 200mm bore cylinder generates 15708 N of push force and 15080 N of pull force. At the maximum 1.0 MPa pressure, the theoretical push force reaches 15708 N.
Yes, the SAI200X275-S is a genuine ISO 15552 profile cylinder, making its mounting dimensions fully interchangeable with other ISO 15552 standard actuators. It uses a G3/4 port and supports standard FA, LB, and TC mounting accessories.
