Decoding SKF NU 213 ECML/P63
- NU 2Series
- Cylindrical roller bearings, NU 2 series. Series differ in outside diameter and width even when the bore is the same.
- 13Bore
- Bore 65 mm (13 × 5).
- ECML/P63Suffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
NU 213 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF NU 213 ECML/P63 measures 65 mm across the bore and 120 mm across the outside diameter; its width is 23 mm (65 x 120 x 23 mm).

SKF NU series cylindrical roller bearings are designed to handle substantial radial loads and high speeds. Their separable construction and ability to accommodate misalignment make them well-suited for tough industrial environments. MR Industrial Accessories supplies this line to customers throughout the United States and Latin America.
The model code NU ... ECML/P... can be broken down as follows: NU means the outer ring has two ribs while the inner ring has none, permitting axial movement. The digits that follow represent the size code in the dimensional series. EC denotes an optimized geometry that increases load capacity. ML stands for the one-piece machined brass cage. P... indicates a special tolerance class, such as P63 in the examples. This coding system lets you quickly identify the bearing's main features.
These bearings appear in many industrial settings: gearboxes, pumps, compressors, machine tools, mining and cement equipment, and power transmission systems. Their capacity for heavy radial loads and their stiffness suit them to high-demand mechanical environments. Sectors including food processing, petrochemicals, steel, and power generation depend on these components to keep production running.
When choosing an NU bearing, consider the radial load, operating speed, and environmental factors. Installation calls for precise alignment between shaft and housing to prevent added stress. Proper lubrication—grease or oil—prolongs bearing life. Sealing depends on the level of contamination; in dirty conditions, extra seals are advised. Also check internal clearance for the application to ensure optimal performance.
For equivalences and interchangeability, SKF NU series bearings can be substituted with products from other manufacturers that use the same standardized designation. However, tolerances and internal design may differ between makers, so verification is important. MR Industrial Accessories provides guidance to select the best option for each equipment's specific needs, ensuring compatibility and performance.

Frequently asked questions
- SKF NU 213 ECML/P63 bearing: what are its dimensions?
- SKF NU 213 ECML/P63 measures 65 mm across the bore and 120 mm across the outside diameter; its width is 23 mm (65 x 120 x 23 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation NU 213.
- What do the ECML suffixes indicate in an NU bearing?
- EC stands for an optimized design with higher load capacity. ML refers to the one-piece machined brass cage, which permits higher speeds and greater resistance. Together, these suffixes denote advanced bearing features.
- How does an NU bearing differ from an NJ bearing?
- The NU bearing has an outer ring with two ribs and an 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 axial fixing requirements.
- How are SKF cylindrical roller bearings lubricated?
- They can be lubricated with grease or oil, depending on speed and temperature. It is essential to follow the manufacturer's recommendations and maintain an adequate lubricant film to reduce wear and extend service life.
