The AirTAC AirTAC SAI200X145 ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 145mm 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 SAI200X145 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. It provides a substantial push force of 15708 N and a pull force of 15080 N at 0.5 MPa. The 145 mm stroke is ideal for high-thrust clamping, pressing, and heavy load manipulation tasks.
This large-bore actuator features a standard carbon steel piston rod and PT tapered port threads. For environments requiring elevated temperatures, the standard TPU seals can be swapped for Viton (H) or NBR (N) alternatives. While this standard configuration lacks a magnet, the extruded aluminum barrel includes dual sensor grooves for adding CMSE or DMSE switches when position feedback is required.

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 push force at 0.7 MPa for assembling bearings and heavy mechanical components.
Provides the robust 145 mm stroke and massive impact force required for forming and stamping thick materials.
Secures oversized workpieces in heavy machining centers where extreme holding power is mandatory.
Selecting this 200 mm bore actuator ensures maximum thrust capability within the AirTAC ISO 15552 range. If the application does not require 15708 N of push force at 0.5 MPa, stepping down to the 160 mm bore offers 10053 N, which reduces air consumption and physical footprint. Because the 145 mm stroke is relatively short for this massive bore, side-load stress on the rod bearing is minimal compared to longer strokes.
This cylinder serves as a dimensionally interchangeable drop-in replacement for other ISO 15552 profile cylinders. To match this exact unit, specify the 200 mm bore, 145 mm stroke, PT port threads, and your desired mounting accessory, such as the TC trunnion or CA clevis. Note that a standard SAI does not hold position if air pressure is lost; for dead-load holding, consider the BSAI clamp-lock variant or an external pilot-operated check valve.
Quick checklist
At an operating pressure of 0.5 MPa, this 200 mm bore cylinder 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.
Yes. The SAI200X145 is a true ISO 15552 profile cylinder, making it dimensionally interchangeable with other ISO 15552 cylinders. Ensure your mounting interface and PT port threads align for a seamless drop-in replacement.
