The SKF 3205 ATN9 is a high-performance double-row angular contact ball bearing engineered to accommodate heavy radial and symmetrical axial loads in applications where space efficiency is paramount. Featuring a robust glass fiber reinforced PA66 polyamide cage (denoted by the ATN9 suffix) centered on the balls, this open-design bearing combines a 25 mm bore, a 52 mm outer diameter, and a 20.6 mm width. It incorporates a nominal 30-degree contact angle, enabling exceptional rigidity and a high capacity for overturning moments, which makes it particularly well-suited for industrial gearboxes, pumps, agricultural machinery, and automotive components. With a basic dynamic load rating of 22 kN and a static load rating of 15.3 kN, the bearing delivers reliable performance under demanding operating conditions while minimizing frictional heat and operational noise. Its structural back-to-back arrangement concept inherently provides a stiff bearing arrangement capable of handling tilting moments, ensuring long-term precision and durability in continuous-duty industrial environments.
