SKF NU series cylindrical roller bearings are components designed to withstand high radial loads and high speeds. Their separable design and the ability to align the rollers with the raceways make them ideal for demanding industrial applications. MR Accesorios Industriales carries this line.
The designation NU … ECM/C…HVA… is interpreted as follows: NU indicates that the inner ring has no flanges and the outer ring does, which allows relative axial displacement. The central number identifies the dimension series. The suffixes ECM indicate an optimized design with machined brass cage and higher load capacity; C3 or C4 define the internal radial clearance; HVA corresponds to a variant with special treatment for high temperatures and speed. For example, NU 210 ECM/C3HVA3091 and NU 215 ECM/C4HVA3091 combine these characteristics for specific applications.
These bearings are used in industries such as metallurgy, cement, mining, paper and power transmission. They are common in gearboxes, pumps, industrial fans, machine tools and continuous process equipment. In Argentina, they are found in steel plants, flour mills, aggregate processing plants and in the food industry. Their ability to withstand heavy radial loads and operate at high speeds makes them suitable for environments with vibrations and high temperatures.
To select the right bearing, take into account the radial load, speed, internal clearance and environmental conditions. The suffix C3 or C4 indicates a clearance greater than normal, recommended for interference fits or thermal gradients. The ECM machined brass cage is suitable for high demands. During assembly, ensure precise alignment between housings and shafts, and adequate lubrication: grease or oil depending on the application. Check the radial clearance after assembly and avoid impacts that could damage the rollers or raceways.
When looking for equivalents from other brands, consider that NU series cylindrical roller bearings follow international dimension standards, which facilitates interchangeability. However, suffixes may vary between manufacturers: the same size may have different cages, clearances or treatments. Always verify the complete part number and technical specifications before replacing a bearing. MR Accesorios Industriales carries SKF, and can advise you on the best option for your equipment.

Frequently Asked Questions
- What are the dimensions of the SKF NU 215 ECM/C4HVA3091 bearing?
- The SKF NU 215 ECM/C4HVA3091 bearing has a 75 mm bore, a 130 mm outside diameter and a 25 mm width (75 x 130 x 25 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation NU 215.
- What does the ECM suffix mean on an SKF NU bearing?
- ECM indicates an optimized design with machined brass cage, which allows higher loads and speeds. It is a robust configuration for demanding applications.
- What is the difference between C3 and C4 in radial clearance?
- C3 and C4 are internal radial clearance classes greater than normal. C4 is looser than C3. They are chosen when there are interference fits or thermal differences between inner and outer rings.
