How to read SKF NU 212 ECP/CNLDR
- NU 2Series
- Cylindrical roller bearings, NU 2 series. For the same bore, each series has a different outside diameter and width.
- 12Bore
- 60 mm bore: 12 × 5.
- ECP/CNLDRSuffix
- SKF suffix: it defines the variant (sealing, cage, internal clearance or other features).
NU 212 is the standard (ISO) basic designation: it defines the type, the series and the bore.
Description

SKF NU series cylindrical roller bearings are separable bearings with a flangeless inner ring, designed to withstand high radial loads and allow axial displacement of the shaft within the housing. They are used in equipment where thermal expansion or longitudinal misalignment must be absorbed without loading the bearing. MR Accesorios Industriales supplies them as part of its SKF bearing line.
The designation is read in parts. NU indicates that the inner ring has no flanges and the outer ring does, so the bearing only guides axially in one direction and allows displacement in the other. The number that follows, for example in NU 209 ECP/CNLDR or NU 2308 ECP/CNLDR, identifies the dimension series: 2 for the light series, 3 for the medium series and 23 for the wide series. The suffixes ECP refer to the optimized design with polyamide cage and CNLDR to the retaining ring groove on the outer ring with reduced radial clearance.
These bearings appear in gearboxes, centrifugal pumps, industrial fans, compressors, machine tools and transmission equipment. In the Argentine market they are found in food, petrochemical, cement and paper plants, and in maintenance workshops that replace fixed bearings with units that allow axial play. The combination of high radial capacity and low friction makes them suitable for long shafts and for positions where the other support is already axially fixed.
To select, you must define the shaft diameter, the working radial load and whether the bearing will be the fixed or the free support. The CNLDR suffix already includes reduced radial clearance and the retaining ring groove, useful when the housing has no shoulder. During assembly, check the alignment of the supports, adequate lubrication according to speed and temperature, and the sealing of the assembly: the bearing itself does not include seals, so protection against contaminants depends on the housing design.
Regarding interchangeability, cylindrical roller bearings of standardized dimension series correspond between manufacturers by their basic designation: a NU 209 from one brand matches the same bore, outer diameter and width as one from another. Internal suffixes, however, are not equivalent between brands and may change cage, clearance or design. Before replacing, compare the complete designation and not just the series number.
If you have the code of the bearing to replace, send it by WhatsApp to MR Accesorios Industriales along with a photo of the assembly and the working conditions. With that we confirm the equivalent SKF designation and the alternatives in the line. We work in the industry and advise on selection, assembly and replacement.

Frequently Asked Questions
- What are the dimensions of the SKF NU 212 ECP/CNLDR bearing?
- The SKF NU 212 ECP/CNLDR bearing has a 60 mm bore, a 110 mm outside diameter and a 22 mm width (60 x 110 x 22 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation NU 212.
- What does the CNLDR suffix mean in an SKF NU bearing?
- CN indicates reduced radial clearance, L designates the retaining ring groove on the outer ring and DR refers to the design with that groove. It is a useful variant when the housing has no support shoulder and the bearing must be retained axially with a ring.
- Can I replace a NU 209 with a NU 209 from another brand?
- The basic designation NU 209 defines the same main dimensions between manufacturers, so dimensional interchange is possible. The design, cage or clearance suffixes may vary between brands, so it is advisable to compare the complete designation before replacing.
- Does this bearing support axial load?
- The NU design guides axially in one direction and allows displacement in the other, so it is not used as a bidirectional fixed support. For combined axial loads it is combined with another bearing or with an arrangement that fixes the shaft in both directions.
