The AirTAC AirTAC SAI200X185 ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 185mm 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 SAI200X185 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a substantial push force of 15708 N at 0.5 MPa, this 200 mm bore unit handles massive loads with reliable pneumatic power. The 185 mm stroke provides robust extension for large-scale forming, pressing, and lifting operations.
Built with a SUS304 stainless steel rod for superior corrosion resistance, this model utilizes PT tapered port threads for a secure pneumatic seal. The extruded aluminum barrel features dual sensor grooves, allowing for flexible position detection when paired with compatible switches.

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 robust 15708 N push force at 0.5 MPa required for large-scale stamping, bending, and heavy-gauge metal forming operations.
Ideal for hydraulic-press-like pneumatic applications where massive downward force and a 185 mm stroke are needed to assemble dense components.
Exerts the necessary power to seat, align, or close heavy industrial molds, utilizing its SUS304 rod for durability in harsh foundry environments.
Selecting this 200 mm bore cylinder is ideal when application forces exceed the 10053 N push capacity of the 160 mm bore variant. For operations requiring less than 15708 N at 0.5 MPa, stepping down to the 160 mm bore optimizes air consumption and physical footprint. This 185 mm stroke is well below the 300 mm side-load threshold, minimizing rod-bearing bending stress.
As a true ISO 15552 profile cylinder, it provides a dimensionally interchangeable mounting interface for seamless drop-in replacement of other ISO 15552 compliant actuators. Note that a standard SAI does not hold position upon loss of air pressure; if the load must be mechanically locked during an exhaust or pressure drop, specify the SAIL or BSAI clamp-lock variant.
Quick checklist
At an operating pressure of 0.5 MPa, this 200 mm bore cylinder generates a push force of 15708 N and a pull force of 15080 N. At 0.7 MPa, the push force increases to 21991 N.
Yes, the SAI200X185 is a genuine ISO 15552 profile cylinder. Its standardized mounting dimensions make it fully interchangeable with other ISO 15552 cylinders, allowing for a direct drop-in replacement using existing PT port plumbing and mounting accessories.
