The SKF NU ECM series cylindrical roller bearing is a component designed to withstand high radial loads and considerable speeds. Its separable design and limited alignment capability make it suitable for demanding industrial applications. At MR Accesorios Industriales we carry this line for the Argentine market, with personalized technical advice. If you need to identify the correct part number for your equipment, send us the part number on WhatsApp and we will help you select it.
The NU ECM series designation is interpreted as follows: the letters NU indicate that the outer ring has two ribs and the inner ring none, which allows relative axial displacement. The letter E indicates an optimized design with higher load capacity, while M corresponds to the machined brass cage. The suffix CNRVQ groups special tolerances and clearances: CN is normal radial clearance, RVQ refers to quality and noise requirements. For example, the part number NU 2214 ECM/CNRVQ335 combines these characteristics for a high-demand bearing.
This type of bearing is used in applications where radial loads are predominant and high rigidity is required, such as gearboxes, industrial pumps, compressors, high-flow fans and machine tools. In Argentina, it is commonly found in the metallurgical, cement, food and mining equipment industries. Its ability to withstand high speeds and its robust construction make it suitable for environments with vibrations and moderate temperatures. The NU ECM series is common in power transmissions and continuous conveying systems.
To correctly select an NU ECM bearing, take into account the radial load, the rotational speed and the environmental conditions. Sealing is a key aspect: if the environment has dust or moisture, consider variants with seals or shields. CN radial clearance is standard, but for applications with high temperatures a larger clearance may be required. During mounting, ensure precise alignment between housing and shaft, and lubricate with the appropriate product according to speed and load. The machined brass cage offers good strength and guidance.
Regarding equivalences and interchangeability, cylindrical roller bearings from different manufacturers can be interchanged if the main dimensions, tolerances and clearance match. The SKF NU ECM series has equivalents in other brands that respect the same standardized dimensions. However, suffix designations may vary, so it is essential to verify the complete part number and technical specifications before replacing. MR Accesorios Industriales carries SKF, which ensures traceability and technical support.

Frequently Asked Questions
- What are the dimensions of the SKF NU 2214 ECM/CNRVQ335 bearing?
- The SKF NU 2214 ECM/CNRVQ335 bearing has a 70 mm bore, a 125 mm outside diameter and a 31 mm width (70 x 125 x 31 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation NU 2214.
- What does the ECM suffix mean on an SKF bearing?
- ECM indicates an optimized design with higher load capacity and a machined brass cage. It is a robust configuration for demanding applications. If you have doubts, ask us with the complete part number.
- What is the difference between an NU and an NJ bearing?
- The NU 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 limits displacement in one direction. The choice depends on the need for axial freedom.
- How do I know if I can replace a bearing from another brand with an SKF one?
- You must verify that dimensions, tolerances and radial clearance match. Suffix designations may vary between manufacturers. At MR we help you validate the equivalence with the exact part number.
