Product Description
The 352213 (GOST current designation) is a Double Row Tapered Roller Bearing with boundary dimensions of 65×120×70mm, featuring a dynamic load rating of 270 kN and static load rating of 305 kN, with a Cor/Cr ratio of 1.130 — reflecting strong shock load resistance and excellent combined radial-axial load handling capability.
Cross-referenced as 97513E under the original GOST designation system, this bearing belongs to the heavy-duty 3522xx series and is specifically engineered for the most demanding industrial environments — including applications with severe misalignment, contamination, vibration, and impact loading.
The 352213 stands out within the 3522xx family for its wide cross-section relative to bore (B/d = 1.077, B=70mm > d=65mm) — providing enhanced moment load resistance and axial stiffness — combined with a limiting speed of 2,200 rpm (grease) / 3,000 rpm (oil). The 3,000 rpm oil-lubrication speed is among the highest in the entire 3522xx series, making the 352213 the definitive solution for 65mm shaft applications where high-speed operation, compact installation space, and substantial load capacity must all be achieved simultaneously.
