The NSK NU series cylindrical roller bearing is a high radial capacity component, designed to withstand heavy loads and considerable speeds. Its construction with cylindrical rollers and a steel cage allows precise operation in demanding applications. It is used in industrial machinery, gearboxes, pumps and power transmission equipment. At MR Accesorios Industriales we quote it according to the part number or size you need.

The NU series designation is interpreted as follows: the letters NU indicate that the inner ring has no flanges, which allows relative axial displacement between ring and shaft. The number that follows (for example, 205, 206, 207) indicates the size and load capacity. The EW suffix identifies a stamped steel window cage, optimized for high speeds and loads. Examples such as NU205EW, NU206EW and NU210EW show this nomenclature. Learn more about this series and its applications.

These bearings are used in industries in Argentina such as food, cement, steel and petrochemical. They are present in gearboxes, conveyor belts, mills, centrifugal pumps and machine tools. Their ability to withstand high radial loads and minimal misalignment makes them suitable for continuously operating rotating equipment. MR Accesorios Industriales sells this series for the Argentine industrial market.

To select the right bearing, take into account the radial load, the rotation speed and the environmental conditions. The NU series allows axial displacement in both directions, so it is used as a free-end support. Check the alignment of the shaft and the housing, and ensure adequate lubrication: grease for low speeds or oil for high speeds. Mounting must be carried out with appropriate tools to avoid damage to the rollers and raceways.

NSK NU series bearings are interchangeable with those of other brands that follow the same dimensional nomenclature, such as SKF, FAG or NTN. However, always verify the tolerances and internal clearance according to the application. If you have the part number of another brand or an unidentified part, we can tell you the compatible equivalent. Interchangeability makes replacement easier and reduces downtime.
