The AirTAC AirTAC SAI200X280 ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 280mm 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 SAI200X280 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Generating 15708 N of push force at 0.5 MPa, this 200mm bore unit handles massive loads with precision. The 280mm stroke is ideal for pressing, lifting, and clamping large assemblies.
Configured with a SUS304 stainless steel rod for superior corrosion resistance, this model uses PT tapered port threads. Because it lacks a magnet, external position sensing must be achieved mechanically. For high-temperature environments up to 70 C, the standard TPU seals provide reliable service.

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 15708 N push force at 0.5 MPa required to form thick metal components in automated press lines.
Lifts heavy machinery subassemblies through its 280mm stroke using a robust SUS304 rod for structural integrity.
Secures oversized industrial pallets during transit, utilizing the massive 3204 kgf theoretical maximum force.
Selecting this 200mm bore cylinder is appropriate when 15708 N at 0.5 MPa is required for your motion task. If your application only needs 10053 N, stepping down to the 160mm bore saves space and air consumption. Conversely, this is the largest standard SAI profile size available.
Because the 280mm stroke exceeds 300mm is not triggered, but you should still evaluate side-load conditions. For applications requiring the load to remain fixed during a complete loss of air pressure, note that the standard adjustable air cushions only decelerate the piston at stroke ends. You must integrate an external pilot-operated check valve or select the BSAI clamp-lock variant to prevent drifting. This model is dimensionally interchangeable per ISO 15552, accepting standard PT G3/4 ports and FA flange accessories.
Quick checklist
At 0.5 MPa operating pressure, the SAI200X280 generates 15708 N of push force and 15080 N of pull force. The theoretical maximum force at 1.0 MPa is 3204 kgf.
No, the standard SAI cylinder will drift downward if air pressure is lost. The adjustable air cushions only decelerate the piston at the end of the stroke. For fail-safe load holding, you need to use the BSAI bidirectional clamp-lock variant or add an external pilot-operated check valve.
