Decoding SKF NJ 2318 ECML/C4VQ015
- NJ 23Series
- Cylindrical roller bearings, NJ 23 series. Series differ in outside diameter and width even when the bore is the same.
- 18Bore
- Bore 90 mm (18 × 5).
- ECML/C4VQ015Suffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
NJ 2318 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description

For equipment that sees heavy radial loads and elevated speeds, SKF NJ series cylindrical roller bearings are a common choice. Their cylindrical rollers and steel cage support precise, durable operation in tough industrial settings. MR Industrial Accessories LLC supplies this SKF line to help you match the right bearing to your machinery.
Reading the part number helps you specify correctly. The prefix NJ means the inner ring has two ribs and the outer ring has one, so the bearing can take axial load in a single direction. The following digits, such as 2312 or 2318, identify the size and series. The ECML suffix points to an optimized version with a machined brass cage, while /C4VQ015 sets a C4 internal radial clearance along with a specific quality and vibration classification. These details matter when you select a bearing.
Typical uses include gearboxes, pumps, compressors, fans, machine tools and power transmission equipment. The ability to handle substantial radial loads at high speeds suits demanding environments. Food processing, petrochemical, steel and cement operations often rely on these bearings in critical processes.
When choosing, consider the radial and axial loads, the rotation speed and the surrounding conditions. In contaminated areas, sealed or shielded variants are worth reviewing. Lubrication must match the temperature and speed. Internal clearance, such as C4, affects how the bearing behaves thermally. During mounting, keep alignment precise and avoid impacts that could harm rollers or raceways.
For equivalences, SKF cylindrical roller bearings can be interchanged with other brands that share the same dimensions and standardized designations. Still, tolerances and radial clearance can differ between manufacturers, so verify them before substituting. A specialist can confirm compatibility and the performance your application expects.
