The AirTAC AirTAC SAI200X425-S ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 425mm 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 SAI200X425-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. It delivers a substantial push force of 15708 N and a pull force of 15080 N at 0.5 MPa. The 425 mm stroke provides the extended travel needed for large-scale material handling and press operations.
This configuration includes a SUS304 stainless steel rod for superior corrosion resistance in harsh environments. It is equipped with a magnet for CMSE and DMSE sensor switches, and features PT tapered ports. As a genuine ISO 15552 extruded aluminum barrel design, it drops in seamlessly with standardized mounting footprints.

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.
Drives large press dies and heavy stamping assemblies where the 15708 N push force at 0.5 MPa is required to form thick steel plates.
Applies consistent clamping pressure on oversized automotive or structural components during automated joining and riveting processes.
Actuates heavy-duty diverter gates on mining or aggregate conveyors, utilizing the 425 mm stroke to redirect substantial material flows.
Select this 200 mm bore actuator when 160 mm (10053 N at 0.5 MPa) lacks the thrust for moving massive loads. For applications requiring position holding without constant air pressure, the standard SAI piston will drift; integrate an external pilot-operated check valve or specify the BSAI clamp-lock variant for secure load retention.
Because the 425 mm stroke creates an extended unsupported rod length, side loads can cause severe bending stress on the rod bearing. Implement an external guide rail or use a guided cylinder to absorb lateral forces and prevent premature wear. This model ensures true ISO 15552 interchangeability with a PT port, 425 mm stroke, and compatible TC trunnion or FA flange accessories.
Quick checklist
At 0.5 MPa operating pressure, 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 SAI200X425-S is built to ISO 15552 mounting dimensions, making it dimensionally interchangeable with other standard profile cylinders of the same bore and stroke. It uses a PT port and supports standard FA flanges or TC trunnions.
