Single row cylindrical roller bearings are designed to accommodate high radial loads in combination with high speeds. Having two integral flanges on the outer ring and no flanges on the inner ring, NUB design bearings can accommodate axial displacement in both directions. The inner ring is extended on both sides, enabling larger axial displacements. An important feature is the separable design, which facilitates mounting and enables the bearing components to be interchanged.
