The AirTAC AirTAC SAI200X250 ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 250mm 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 SAI200X250 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty pneumatic applications. Delivering a substantial push force of 15708 N at 0.5 MPa, this 200 mm bore unit is built to move massive loads reliably. The 250 mm stroke provides ample travel for large-scale material handling. As a genuine AirTAC component, it ensures rigorous manufacturing standards.
This specific configuration features a SUS304 stainless steel piston rod (material code B) for superior corrosion resistance in harsh environments. It utilizes PT tapered port threads for a secure, leak-free pneumatic connection. Note that this variant does not include a magnet; if position sensing is required, the -S option with CMSE or DMSE switches mounted in the dual barrel grooves would be necessary.

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 the 15708 N push force at 0.5 MPa required to actuate large industrial stamping and forming presses.
The SUS304 stainless steel rod provides corrosion resistance while moving heavy injection molds in humid factory environments.
Uses the 250 mm stroke to shift heavy bulk material flows on high-capacity aggregate or mining conveyor lines.
Selecting the SAI200X250 is appropriate when application forces exceed the 10053 N push capacity of the 160 mm bore at 0.5 MPa. Because the 250 mm stroke is substantial, designers must account for side-load risks; long unsupported rods are susceptible to bending under lateral forces. Utilizing external guide rails or a fully guided cylinder variant is strongly recommended to prevent premature rod-bearing wear.
This model serves as a drop-in replacement for other ISO 15552 profile cylinders, matching standardized mounting dimensions for foot (LB), flange (FA/FB), and trunnion (TC) accessories. Remember that the standard double-acting SAI does not hold position if air pressure is lost; for dead-load holding, integrate an external pilot-operated check valve or specify the BSAI clamp-lock variant.
Quick checklist
At 0.5 MPa, the SAI200X250 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 SAI200X250 is dimensionally interchangeable per ISO 15552. You can drop it into existing foot, flange, or trunnion mounts designed for standard profile cylinders, provided you use the matching G3/4 port.
