Decoding SKF NU 212 ECP/CNLDR
- NU 2Series
- Cylindrical roller bearings, NU 2 series. Series differ in outside diameter and width even when the bore is the same.
- 12Bore
- Bore 60 mm (12 × 5).
- ECP/CNLDRSuffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
NU 212 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF NU 212 ECP/CNLDR measures 60 mm across the bore and 110 mm across the outside diameter; its width is 22 mm (60 x 110 x 22 mm).

The SKF NU line covers cylindrical roller bearings built with a separable inner ring that carries no flanges. That layout lets the bearing take heavy radial load while the shaft moves lengthwise inside the housing, which is what you want wherever thermal growth or slight longitudinal offset has to be absorbed instead of pushed into the bearing. MR Industrial Accessories LLC offers these bearings as part of the SKF range it supplies to plants and maintenance shops.
Reading the code helps before you order. The NU prefix means the outer ring keeps its flanges while the inner ring has none, so the bearing locates the shaft in one axial direction and stays free in the other. The digits after the prefix set the dimension series, as in NU 209 ECP/CNLDR or NU 2308 ECP/CNLDR: 2 is the light series, 3 the medium series and 23 the wide series. ECP marks the optimized version with a polyamide cage, and CNLDR tells you the outer ring carries a retaining ring groove and the bearing runs with reduced radial clearance.
Typical positions are gearboxes, centrifugal pumps, industrial fans, compressors, machine tools and transmission equipment. Food, petrochemical, cement and paper plants use them, and maintenance crews often swap a fixed bearing for one of these where the shaft needs room to move. High radial capacity together with low friction suits long shafts and any spot where the opposite support is already fixed axially.
Selection comes down to three things: shaft diameter, the radial load in service, and whether the bearing works as the fixed or the free support. The CNLDR variant brings the reduced clearance and the groove already built in, which helps when the housing has no shoulder to seat against. At assembly, verify that the supports line up, that lubrication matches speed and temperature, and that the housing seals the position properly, since the bearing ships without seals and relies on the housing for contaminant protection.
On interchange, cylindrical roller bearings in standardized dimension series match across makers by basic designation: a NU 209 shares bore, outer diameter and width with the same designation from any brand. Suffixes are a different story and are not interchangeable, because cage, clearance and internal design can differ. Compare the full designation, not just the series number, before you replace anything.

Frequently asked questions
- SKF NU 212 ECP/CNLDR bearing: what are its dimensions?
- SKF NU 212 ECP/CNLDR measures 60 mm across the bore and 110 mm across the outside diameter; its width is 22 mm (60 x 110 x 22 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation NU 212.
- What does CNLDR indicate on an SKF NU bearing?
- CN stands for reduced radial clearance, L for the retaining ring groove machined on the outer ring, and DR for that grooved design. It is the variant to pick when the housing offers no shoulder and a ring has to hold the bearing axially.
- Is a NU 209 interchangeable with a NU 209 from another maker?
- The basic designation NU 209 fixes the main dimensions, so the parts fit the same seat. Suffixes covering design, cage or clearance can differ from brand to brand, so check the complete designation before substituting.
- Does an NU bearing carry axial load?
- It locates the shaft in one direction and leaves it free in the other, so it does not act as a bidirectional fixed support. Where axial load comes from both directions, pair it with another bearing or an arrangement that holds the shaft in both.
