The SKF NU307ECJC3 is a high-quality single-row cylindrical roller bearing designed for heavy radial loads and high speeds. Featuring a 35 mm bore, 80 mm outer diameter, and 21 mm width, this bearing has a C3 radial internal clearance, which is greater than normal, allowing for thermal expansion and misalignment. The NU design indicates that the outer ring has two integral flanges, and the inner ring has no flanges, allowing for axial displacement within the bearing. It is equipped with a pressed steel cage (ECJ) and is suitable for various industrial applications requiring robust and reliable performance.
