NU 3980 ECMA
Additional Details
Single row cylindrical roller bearings are designed to handle high radial loads combined with high speeds. With double edges on the outer ring and no edges on the inner ring, NU series bearings can accommodate axial movement in both directions. A key feature is their separable design, which simplifies installation and allows for easy replacement of bearing components.
