The AirTAC AirTAC SAI200X900 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 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. It delivers a robust push force of 15708 N at 0.5 MPa, extending across a 900 mm stroke. This size suits massive press operations and heavy material handling where substantial displacement is mandatory.
Built with an extruded aluminum barrel, this unit features a SUS420J2 stainless steel piston rod (material code A) for superior corrosion resistance. It uses a PT tapered port thread and lacks a standard magnet, meaning position sensing via CMSE or DMSE switches requires adding the -S option at order.

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 sheets in large-scale automotive stamping presses.
Safeguards the 900 mm stroke needed to extract heavy injection molds from deep cavities on automated carousel lines.
Powers heavy-duty diverters on mining or aggregate conveyors, moving large volumes of raw bulk material rapidly.
Selecting this 200 mm bore provides maximum thrust, stepping up considerably from the 160 mm bore which offers 10053 N at 0.5 MPa. For applications requiring less than 15080 N pull force, dropping a bore size saves space and air consumption. The 900 mm stroke falls within the 1500 mm standard limit for this bore.
At 900 mm of extension, the unsupported rod is highly susceptible to bending under side loads. Employing an external guide rail or a dedicated guided cylinder is strongly recommended to prevent premature rod-bearing wear. Note that the adjustable air cushions only decelerate the piston at stroke ends; they do not hold a load. If static holding is required during air loss, specify the SAIL or BSAI variant. To match ISO 15552 interchangeability, confirm the 200 mm bore, 900 mm stroke, G3/4 port, and appropriate mounting accessory like the TC trunnion.
Quick checklist
At 0.5 MPa operating pressure, the SAI200X900 delivers a push force of 15708 N and a pull force of 15080 N. At the maximum 1.0 MPa, the theoretical push force reaches 3204 kgf.
Yes, the SAI200X900 is dimensionally interchangeable per ISO 15552. It serves as a drop-in replacement for other ISO 15552 profile cylinders, provided the 200 mm bore, 900 mm stroke, and G3/4 port match your existing layout.
