Decoding SKF NJ 2318 ECP
- 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).
- ECPSuffix
- 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.

SKF NJ series cylindrical roller bearings are built to carry heavy radial loads at considerable speed. The cylindrical roller and polyamide cage design supports precise, durable operation in demanding industrial equipment. MR Industrial Accessories supplies this line to customers across the United States and in several Latin American countries.
Reading the code: NJ means the outer ring has one rib and the inner ring has two, so the bearing can guide the shaft axially in one direction. The digits that follow identify the size and dimension series. The ECP suffix points to an optimized internal design with a polyamide cage and higher-capacity rollers.
These bearings appear in machine tools, centrifugal pumps, speed reducers, compressors and power transmission equipment. Their capacity for heavy radial loads makes them a common choice in metallurgical, food, petrochemical and agro-industrial operations where reliability matters.
Selection depends on radial load, rotation speed and the surrounding environment. Where dust or moisture is present, consider sealed variants. Lubrication should match the operating regime, and shaft-to-housing alignment helps avoid extra stresses. Proper mounting tools and correct internal clearance support good performance and longer service life.
For interchangeability, SKF NJ series bearings can be replaced by products from other manufacturers that follow the same international designation. Tolerances and internal design can differ, though, so load capacity and suffixes should always be checked. Consulting a specialist and validating critical dimensions is the safe route for a replacement.
