SKF NU series cylindrical roller bearings are components designed to withstand high radial loads and considerable speeds. Their separable design and alignment capability make them ideal for demanding industrial applications. MR Accesorios Industriales carries this line, providing reliable solutions for Argentine industry.
The designation NU … ECML/P… is interpreted as follows: the prefix NU indicates that the outer ring has two ribs and the inner ring none, which allows relative axial displacement. The number that follows is the size code according to the dimensional series. The suffix EC indicates an optimized design with higher load capacity, ML indicates the one-piece machined brass cage, and P… specifies the special tolerance class, for example P63 in the examples. This nomenclature allows quick identification of the bearing's key characteristics.
These bearings are used in a wide variety of industrial applications in Argentina, such as gearboxes, pumps, compressors, machine tools, mining and cement equipment, and power transmission systems. 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 power generation rely on these components to keep their production processes running.
To correctly select an NU bearing, it is essential to consider the radial load, operating speed and environmental conditions. Mounting requires precise alignment between the shaft and the housing to avoid additional stresses. Adequate lubrication, whether grease or oil, extends the bearing's service life. Sealing will depend on the contamination present; in dirty environments additional seals are recommended. In addition, internal clearance must be verified according to the application to ensure optimal operation.
Regarding equivalences and interchangeability, SKF NU series bearings can be replaced by products from other brands that follow the same standardized designation. However, it is important to verify tolerances and internal design, as they may vary between manufacturers. MR Accesorios Industriales offers advice to find the best option according to the specific requirements of each equipment, ensuring compatibility and performance.

Frequently Asked Questions
- What are the dimensions of the SKF NU 2216 ECML/P63 bearing?
- The SKF NU 2216 ECML/P63 bearing has a 80 mm bore, a 140 mm outside diameter and a 33 mm width (80 x 140 x 33 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation NU 2216.
- What does the ECML suffix mean in an NU bearing?
- EC indicates an optimized design with higher load capacity. ML refers to the one-piece machined brass cage, which allows higher speeds and resistance. Together, these suffixes identify advanced bearing characteristics.
- What is the difference between an NU and an NJ bearing?
- The NU bearing has the outer ring with two ribs and the inner ring without ribs, allowing axial displacement. The NJ has one rib on the inner ring, which restricts displacement in one direction. The choice depends on the axial fixing requirements.
- How are SKF cylindrical roller bearings lubricated?
- They can be lubricated with grease or oil, depending on speed and temperature. It is crucial to follow the manufacturer's recommendations and maintain an adequate lubricant film to reduce wear and extend service life.
