SKF NU series cylindrical roller bearings are components designed to withstand high radial loads and considerable speeds. Their design with cylindrical rollers and steel cage allows precise and durable operation in demanding industrial applications. They are ideal for machine tools, electric motors, pumps and transmission equipment. At MR Accesorios Industriales we market this line with the backing of more than 80 years of experience in the industry.

The designation NU … ECJ/C… is interpreted as follows: NU indicates that the bearing has two ribs on the outer ring and none on the inner ring, which allows relative axial displacement. The following number is the size code according to the dimension series. EC means it incorporates optimized-design rollers, with higher load capacity. J indicates stamped steel cage. C3 indicates an internal radial clearance greater than standard. For example, NU 206 ECJ/C3 corresponds to a bearing of series 2, with the mentioned characteristics.

These bearings are used in a wide variety of industrial applications in Argentina. They are common in electric motors, centrifugal pumps, compressors, gearboxes, machine tools and power transmission equipment. Their ability to withstand heavy radial loads and their rigidity make them suitable for environments with high mechanical demands. Industries such as food, petrochemical, steel and general manufacturing use them to ensure continuous and reliable operation.

To correctly select a cylindrical roller bearing, it is essential to consider radial load, rotation speed and environmental conditions. Assembly requires precise alignment between shaft and housing to avoid additional stresses. Proper lubrication, whether grease or oil, extends service life. Sealing will depend on the environment: in contaminated environments, additional protection is recommended. C3 radial clearance is useful when thermal expansion or interference fits are expected. Always check shaft and housing tolerances.

Regarding equivalences and interchangeability, SKF NU series bearings can be replaced by products from other manufacturers that follow the same international designation. However, it is important to verify critical dimensions and load capacities, as there may be variations in materials and treatments. To ensure full compatibility, always consult with our technical team and provide the complete code of the bearing you need to replace.
