Double row cylindrical roller bearings are designed to accommodate high radial loads in combination with high speeds. Having three flanges on the outer ring and no flanges on the inner ring, NNU design bearings can accommodate axial displacement in both directions. An important feature is the separable design, which facilitates mounting and enables the bearing components to be interchanged.
