Decoding SKF NJ 2213 ECML/C3
- NJ 22Series
- Cylindrical roller bearings, NJ 22 series. Series differ in outside diameter and width even when the bore is the same.
- 13Bore
- Bore 65 mm (13 × 5).
- ECML/C3Suffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
NJ 2213 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF NJ 2213 ECML/C3 measures 65 mm across the bore and 120 mm across the outside diameter; its width is 31 mm (65 x 120 x 31 mm).

For heavy radial loads and high speeds, the SKF NJ series cylindrical roller bearing is a dependable choice in industrial machinery. Its single-direction axial guidance comes from a design with two ribs on the inner ring and one on the outer ring, making it well suited for gearboxes, pumps, and power transmission equipment that need precise shaft positioning.
The bearing code follows a clear pattern: NJ identifies the rib configuration, the number indicates the size, ECML denotes a machined brass window cage guided by the inner ring, and C3 or C4 specifies internal radial clearance. Typical part numbers include NJ 219 ECML/C3, NJ 230 ECML/C3, and NJ 316 ECML/C4.
These bearings are used across steel, cement, mining, paper, and general machinery manufacturing. In North and South America, they are found in speed reducers, centrifugal pumps, industrial fans, and other transmission equipment where high radial loads and rigidity are required.
When selecting a bearing, account for radial and axial loads, speed, and operating environment. C3 or C4 clearance is appropriate when thermal expansion or interference fits are expected. Lubrication should match temperature and speed—oil is often preferred at high speeds. Proper shaft-to-housing alignment and effective sealing are also essential to prevent contamination.
SKF NJ series bearings can be interchanged with equivalents from FAG, NSK, or NTN if the dimensional designation and suffixes match. Always verify the complete code and operating conditions before substituting a bearing from a different manufacturer.

Frequently asked questions
- SKF NJ 2213 ECML/C3 bearing: what are its dimensions?
- SKF NJ 2213 ECML/C3 measures 65 mm across the bore and 120 mm across the outside diameter; its width is 31 mm (65 x 120 x 31 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation NJ 2213.
- What does the ECML suffix mean on an SKF NJ bearing?
- ECML indicates a machined brass window cage guided by the inner ring, a common configuration in cylindrical roller bearings for demanding applications.
- When should I specify C3 or C4 internal clearance?
- C3 or C4 clearance is recommended when interference fits, thermal expansion, or high speeds are present, as it allows dimensional changes without compromising operation.
- Can I replace an SKF NJ bearing with a different brand?
- Yes, if the dimensional designation and suffixes match. Brands such as FAG, NSK, or NTN offer equivalents, but verify tolerances and clearance before interchanging.
