The SKF NNU series cylindrical roller bearings are components with high radial load capacity, designed to withstand high forces and considerable speeds. Their double row construction and bronze cage make them suitable for demanding applications in industrial machinery. At MR Accesorios Industriales we supply them as part of our SKF bearing line, backed by more than 80 years of experience in the field.

The NNU designation corresponds to double row cylindrical roller bearings with a flangeless inner ring and a flanged outer ring. The B suffix indicates a design with a machined bronze cage, of high strength. SPC indicates special tolerance for precision applications, and W33 indicates the presence of a lubrication groove and holes in the outer ring. For example, NNU 4930 B/SPC3W33 combines these features in a bearing with 150 mm bore diameter, while NNU 4932 B/SPC3W33 and NNU 4956 B/SPC3W33 correspond to larger sizes. Knowing these codes makes identification easier when replacing.

These bearings are used in applications requiring high radial load capacities and rigidity, such as gearboxes, machine tool spindles, rolling mills, industrial pumps and mining equipment. In Argentina, they are common in the metallurgical, cement, paper and heavy machinery manufacturing industries. Their double row design allows them to withstand combined loads and moments, although their main function is radial load.

To correctly select an NNU bearing, it is essential to consider the radial load, rotational speed and environmental conditions. Mounting requires precise alignment and adequate lubrication, either with grease or oil, depending on the application. The lubrication groove and holes (W33) facilitate relubrication in service. It is recommended to verify the internal clearance and use appropriate mounting tools to avoid damage to the rollers and raceways.

Regarding equivalences, SKF NNU series bearings can be interchanged with products from other brands that follow the same dimensional and design designation. It is important to verify tolerances and cage design, as they may vary between manufacturers. For safe interchangeability, always consult the technical specifications and ensure that the bearing meets the load and speed requirements of your equipment.
