The AirTAC AirTAC SAI200X900-S ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 900mm 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 SAI200X900-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty applications. It delivers a substantial push force of 15708 N at 0.5 MPa, extending across a 900 mm stroke to handle massive loads with precision. The extruded aluminum barrel design omits tie-rods, providing a clean profile that drops directly into standardized ISO 15552 mounting interfaces.
This specific configuration incorporates a SUS420J2 stainless steel piston rod for superior corrosion resistance and mechanical durability. It includes a built-in magnet (-S) for seamless integration with CMSE or DMSE sensor switches, which mount directly into the dual grooves on the barrel. The fluid porting utilizes PT tapered threads, ensuring a robust, leak-free pneumatic connection in demanding industrial environments.

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 required to actuate large stamping presses and heavy-gauge metal forming equipment over a 900 mm travel distance.
Ideal for applying high clamping pressure on oversized structural components during industrial welding and adhesive curing processes.
Drives the heavy platens of large-tonnage plastic injection molding machinery, utilizing the adjustable cushioning to smoothly decelerate massive moving masses.
Selecting this 200 mm bore unit is appropriate when applications exceed the 10053 N push force available at 0.5 MPa from the smaller 160 mm bore variant. The 900 mm stroke operates within the 1500 mm maximum standard stroke limit for this bore, but the extended length requires careful mechanical planning. An unsupported rod of this length is highly susceptible to bending under side loads; utilizing an external linear guide or a guided cylinder carriage is essential to prevent premature rod-bearing wear.
For interchangeability, this model matches the ISO 15552 footprint exactly, allowing direct replacement of comparable profile cylinders. Specify the required mounting accessory—such as a TC trunnion or CA clevis—and ensure your pneumatic plumbing accommodates the G3/4 port size. If the machinery must maintain a vertical load position during a complete loss of air pressure, note that the standard adjustable air cushion only decelerates the piston at stroke end and does not function as a brake; an external rod lock or the SAIL variant is required for secure holding.
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 SAI series is built to exact ISO 15552 dimensional standards, making it a drop-in replacement for other standard profile cylinders with identical bore and stroke dimensions. Ensure your mounting hardware and G3/4 porting match the interface.
