The SKF NU series cylindrical roller bearing is a component designed to withstand high radial loads and operate at high speeds. Its dismountable design facilitates assembly and maintenance in industrial equipment. It is used in applications requiring high load capacity and rigidity, such as gearboxes, pumps and process machinery. At MR Accesorios Industriales we supply this official brand and advise you to choose the right bearing for your application.

The NU series designation is interpreted as follows: the letters NU indicate that the outer ring has two ribs and the inner ring none, which allows relative axial displacement between ring and shaft. The numbers that follow indicate the size and dimension series. The suffixes EM and C3 provide key information: EM indicates a design with machined brass cage and higher-capacity rollers, while C3 indicates an internal radial clearance greater than standard. For example, the code NU 319 EM/C3 combines these characteristics for a high-demand bearing.

This type of bearing is used in industries such as cement, steel, paper and food. In Argentina, it is common to find it in speed reducers, mills, conveyor belts, centrifugal pumps and industrial fans. Its ability to withstand heavy radial loads and its fatigue resistance make it suitable for equipment operating continuously. It is also used in applications where thermal expansion of the shaft requires freedom of axial movement.

To correctly select an NU bearing, take into account the radial load, rotation speed and environmental conditions. C3 clearance is recommended when there are significant thermal gradients between the inner and outer rings, as it compensates for differential expansion. Lubrication must be chosen according to temperature and speed: grease for slow applications or oil for high revolutions. During assembly, ensure precise alignment between the supports and avoid impacts that could damage the rollers or raceways. Sealing will depend on the contamination of the environment.

Regarding equivalences and interchangeability, cylindrical roller bearings from different brands can be interchanged if the main dimensions and radial clearance match. However, not all suffixes have the same meaning between manufacturers. Therefore, always verify the complete code and tolerances before replacing a bearing. At MR Accesorios Industriales we can help you find the right equivalent reference for your equipment.
