SKF NU series cylindrical roller bearings are components designed to withstand high radial loads and considerable speeds. Their design with cylindrical rollers and parallel raceways enables high performance and a long service life in demanding industrial applications. They are ideal for rotating machinery where radial rigidity and load capacity are required, such as electric motors, pumps, compressors and transmission equipment. At MR Accesorios Industriales we supply this SKF line to provide reliable solutions to Argentine industry.

The NU designation in SKF cylindrical roller bearings indicates that the outer ring has two ribs and the inner ring has no ribs, which allows relative axial displacement between ring and shaft. The number that follows, as in NU 1005 or NU 1006, identifies the size and dimensional series. Additional suffixes may indicate design variants, such as brass cage, special heat treatment or internal clearance, although not all are available in every size. Knowing this nomenclature makes it easier to select the right bearing for the application.

These bearings are used in a wide range of industries in Argentina, including metallurgy, cement, paper, food and petrochemical. They are common in large electric motors, gearboxes, centrifugal pumps, industrial fans and machine tools. Their ability to withstand heavy radial loads and operate at high speeds makes them suitable for equipment subjected to continuous work. They are also used in applications where shaft thermal expansion must be compensated, thanks to their sliding design.

To select an NU bearing, it is essential to consider the radial load, operating speed and environmental conditions. Mounting must ensure precise alignment between shaft and housing to avoid additional stresses. Proper lubrication, whether grease or oil, extends service life and reduces wear. Sealing will depend on the contamination present; in dirty environments additional seals are recommended. Internal clearance should be chosen according to the working temperature and mounting fit. Careful installation with suitable tools prevents damage to rollers and raceways.

Regarding equivalences, SKF NU series cylindrical roller bearings can be interchanged with products from other brands that follow the same dimensional and design designation, such as NU series from European or Asian manufacturers. However, it is crucial to verify tolerances and internal clearance, as they may vary between manufacturers. For replacements, it is always advisable to consult a specialist and provide the complete part number of the original bearing. At MR Accesorios Industriales we can advise you on interchangeability and available options.
