SKF NU series cylindrical roller bearings with the ECMA suffix are components designed to withstand high radial loads and considerable speeds. Their separable design and machined brass cage make them suitable for demanding applications in industrial machinery. MR Accesorios Industriales carries this line as part of its SKF bearing catalog, with more than 80 years of experience in the field.
The NU designation indicates that the outer ring has no flanges, while the inner ring has two flanges. This allows relative axial displacement between ring and shaft, so these bearings are used as a floating support in two-support arrangements. The ECMA suffix indicates an optimized design with a machined brass cage, roller-guided, and increased load capacity. For example, NU 2264 ECMA and NU 2344 ECMA are part numbers that follow this nomenclature and allow the construction features to be identified.
These bearings are used in applications where radial loads are significant and rotational speeds are moderate or high. They are found in gearboxes, machine tools, industrial pumps, high-flow fans, rolling mills and mining equipment. In Argentina, they are common in the oilseed, steel, cement and agricultural machinery manufacturing industries, where robustness and the ability to withstand combined loads are critical to production continuity.
To correctly select an NU ECMA bearing, it is essential to consider the radial load it will have to withstand, the operating speed and the environmental conditions. The machined brass cage offers greater resistance to temperature and dynamic stresses, but requires adequate lubrication. During mounting, precise alignment between supports must be ensured and impacts that could damage the rollers or raceways must be avoided. Sealing will depend on the environment: in contaminated environments, additional seals or bearings with integrated seals are recommended.
As for interchangeability, SKF NU series bearings with the ECMA suffix can be replaced by equivalent products from other brands that follow the same standardized designation. However, it is important to verify tolerances and internal clearance, as they may vary between manufacturers. To ensure full compatibility, it is always advisable to consult a specialist and provide the complete part number of the original bearing. MR Accesorios Industriales can advise you on selecting the most suitable alternative.

Frequently Asked Questions
- What does the ECMA suffix mean on an SKF bearing?
- The ECMA suffix indicates that the bearing has a machined brass cage, roller-guided, and an optimized design for higher load capacity. The letter E refers to the reinforced execution, and CMA to the machined brass cage.
- Does this bearing support axial loads?
- No, NU bearings do not support axial loads because the outer ring has no flanges. They are used as a floating support to allow axial displacement. For axial loads, other designs such as NJ or NUP must be used.
- How do I know if I can replace an NU ECMA bearing with another brand?
- You can replace it with another bearing that has the same standardized designation, but verify the tolerances and internal clearance, which may vary. Consult us with the complete part number and we will advise you on interchangeability.
