NNUB cylindrical roller bearings are components with high radial load capacity, designed to withstand heavy loads and considerable speeds. They are used in industrial applications requiring rigidity and precision, such as machine tools, gearboxes and power transmission equipment. MR Accesorios Industriales sells this RKB line, with more than 80 years of experience in the field, and advises you on selecting the right bearing for your application.

The NNUB designation identifies double-row cylindrical roller bearings with a cylindrical bore, according to RKB nomenclature. The numbers that follow, as in NNUB 315033 or NNUB 320117, correspond to an internal code that defines dimensions and specific characteristics of each size. To correctly interpret these references, it is essential to consult the drawings or manuals of the equipment where the bearing will be mounted, since each code corresponds to a particular geometry.

These bearings are used in a wide variety of industries in Argentina, including metallurgy, cement, mining and food processing. They are common in gearboxes, rolling mills, paper machines, high-flow pumps and material handling equipment. Their ability to withstand heavy radial loads and their rigidity make them suitable for assemblies requiring high precision and reliability under demanding conditions.

To select the right NNUB bearing, take into account the radial load, the rotational speed and the environmental conditions. It is crucial to verify the bore and shaft fits, as well as the recommended internal clearance. Mounting must be done with suitable tools, avoiding direct blows. Lubrication, whether with grease or oil, must be the one specified for the application, and correct alignment between shaft and housing is essential to avoid premature failures.

When looking for a replacement, it is possible to find equivalent bearings from other brands that follow the same dimensional nomenclature. However, tolerances and internal design may vary between manufacturers. That is why, if you bring the code from another brand or an unidentified part, at MR we tell you the compatible alternative or quote the exact code you need. Interchangeability must be technically validated to ensure equipment performance.
