How to read SKF NU 214 ECML/C3H
- NU 2Series
- Cylindrical roller bearings, NU 2 series. For the same bore, each series has a different outside diameter and width.
- 14Bore
- 70 mm bore: 14 × 5.
- ECML/C3HSuffix
- SKF suffix: it defines the variant (sealing, cage, internal clearance or other features).
NU 214 is the standard (ISO) basic designation: it defines the type, the series and the bore.
Description
The SKF NU 214 ECML/C3H bearing has a 70 mm bore, a 125 mm outside diameter and a 24 mm width (70 x 125 x 24 mm).

SKF NU series cylindrical roller bearings are components designed to withstand high radial loads and considerable speeds. Their design with cylindrical rollers and machined brass cage allows precise operation in demanding applications. They are used in industrial machinery, gearboxes, pumps and power transmission equipment. MR Accesorios Industriales carries this line as a brand, with technical advice to select the right execution.
The designation NU … ECML/C…H is interpreted as follows: NU indicates that the outer ring has two ribs and the inner ring none, which allows relative axial displacement. The following number (for example, 212 or 214) corresponds to the dimensional series size. EC indicates an optimized design with higher load capacity. ML identifies the machined brass cage, roller-guided. C…H indicates a special execution with increased radial clearance and heat treatment for high temperatures. The examples NU 212 ECML/C3H and NU 214 ECML/C3H show these variants.
These bearings are used in applications where radial loads predominate and high rigidity is required. They are common in speed reducers, gearboxes, centrifugal pumps, compressors, machine tools and mining equipment. In Argentina, they are found in the food, petrochemical, steel and cement industries. Their ability to withstand high radial loads and operate at high speeds makes them suitable for power transmissions and roller systems in production lines.
To select correctly, take into account the radial load, rotation speed and environmental conditions. The ML brass cage is suitable for high temperatures and severe loads. The suffix C…H indicates a larger radial clearance, necessary when there are thermal gradients between rings. Mounting requires precise alignment and adequate lubrication, since these bearings are not self-aligning. Check the fit on the shaft and in the housing according to the type of load. Lubrication can be grease or oil, depending on speed and operating temperature.
Regarding equivalences, cylindrical roller bearings from other brands with similar designations may be interchangeable, but it is essential to verify dimensions, tolerances and load capacity. The SKF NU series has equivalents in other standards, but codes should not be assumed without confirmation. MR Accesorios Industriales carries SKF as a brand and can advise you on interchangeability with other brands, always respecting the technical specifications of each application.

Frequently Asked Questions
- What are the dimensions of the SKF NU 214 ECML/C3H bearing?
- The SKF NU 214 ECML/C3H bearing has a 70 mm bore, a 125 mm outside diameter and a 24 mm width (70 x 125 x 24 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation NU 214.
- What does the ECML suffix mean in an SKF bearing?
- EC indicates an optimized design with higher load capacity. ML refers to the machined brass cage, roller-guided. This combination is common in high-demand applications.
- When is a bearing with C3H radial clearance recommended?
- The C3H suffix indicates increased radial clearance and heat treatment for high temperatures. It is recommended when there are thermal gradients between the shaft and the housing, or in applications where thermal expansion is significant.
- Are SKF NU bearings interchangeable with other brands?
- They may be interchangeable if dimensions, tolerances and load capacity match. Always verify the technical specifications and consult with MR Accesorios Industriales to confirm the equivalence before replacing.
