The double-row cylindrical roller bearing of the NU E series is a component designed to withstand high radial loads and moderate speeds. It is used in industrial applications requiring high load capacity and rigidity, such as heavy machinery, mining equipment and transmission systems. Its double-row design allows uniform load distribution, which contributes to a longer bearing service life. MR Accesorios Industriales sells this series with the NTN guarantee, a brand MR sells.
The designation of the NU E series is interpreted as follows: the letters NU indicate that the bearing has two rows of cylindrical rollers and that the inner ring has no flanges, which allows axial displacement. The final letter E indicates an internal optimization that increases load capacity. The codes of the NU E series correspond to different dimension series, such as 22 and 23, with specific dimensions and capacities that can be checked via WhatsApp.
These bearings are used in a wide variety of industrial applications in Argentina, such as gearboxes, reducers, mills, crushers, pumps, fans and conveying equipment. They are common in the mining, cement, steel, paper and energy sectors. Their ability to withstand heavy radial loads and their rigidity make them suitable for machinery operating under demanding conditions, with vibrations and combined loads.
To correctly select a bearing of the NU E series, 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. Sealing can be open or with protective plates, depending on environmental contamination. It is advisable to check the internal clearance and use suitable mounting tools to avoid damage to the rollers and raceways.
Regarding equivalences and interchangeability, double-row cylindrical roller bearings from other brands can replace those of the NU E series as long as dimensions and capacities are respected. It is important to compare tolerances and internal design to ensure optimal operation. MR Accesorios Industriales can advise you on compatibility with other brands and codes, and quote the option that best suits your equipment.
