The AirTAC AirTAC SAI200X270-S ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 270mm 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 SAI200X270-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty operations, delivering a substantial push force of 15708 N at just 0.5 MPa. Its 270 mm stroke is ideal for moving large masses or executing long-travel presses in demanding industrial environments.
This specific configuration incorporates a highly corrosion-resistant SUS304 stainless steel piston rod and includes a built-in magnet for non-contact position sensing. The barrel features dual sensor grooves designed to seamlessly accept CMSE or DMSE switches, while the pneumatic ports utilize PT tapered threads for secure, leak-free connections.

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 immense 15708 N push force required to form thick metal plates and operate large mechanical presses.
Drives robust joining operations and bearing insertion tasks where high impact force and a 270 mm travel distance are necessary.
Actuates heavy-duty lifting gates, diverter arms, and large-scale pallet positioning systems in automated warehouses.
Selecting this 200 mm bore unit is appropriate when your application demands extreme thrust that smaller bores cannot provide, such as stepping up from a 160 mm bore (which offers 10053 N push at 0.5 MPa). Because the 270 mm stroke exceeds the 300 mm side-load warning threshold, it is crucial to manage rod-bearing bending; using an external guide rail or a fully guided cylinder will prevent premature wear.
As a dimensionally interchangeable ISO 15552 profile cylinder, this model serves as a drop-in replacement for other standard 200 mm bore cylinders, matching the exact mounting footprint and PT port locations. If the machinery must hold a load in place without continuous air pressure, a standard SAI will drift; instead, specify the SAIL variant with an air-released lock or the BSAI bidirectional clamp-lock.
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 SAI200X270-S is a genuine ISO 15552 profile cylinder, making its mounting dimensions and port locations fully interchangeable with other standard ISO 15552 cylinders of the same bore size.
