Decoding SKF NU 2315 ECML/C4VA305
- NU 23Series
- Cylindrical roller bearings, NU 23 series. Series differ in outside diameter and width even when the bore is the same.
- 15Bore
- Bore 75 mm (15 × 5).
- ECML/C4VA305Suffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
NU 2315 is the standard ISO basic designation, which sets the bearing type, series and bore.

The SKF NU 2315 ECML/C4VA305 is a cylindrical roller bearing built for high radial loads and high speeds. Its cylindrical rollers distribute load evenly across the raceway, which suits demanding industrial equipment. MR Industrial Accessories supplies this SKF bearing to maintenance and purchasing teams across the United States and Latin America.
Reading the designation helps you confirm the bearing before you order. The NU prefix means the inner ring has no flanges, so the shaft can move axially relative to the housing. ECML points to an optimized internal design with a machined brass cage, roller-guided windows and higher load capacity. C4VA305 combines a C4 internal radial clearance, larger than standard, with the VA305 special execution variant, which can involve particular tolerances or surface treatments. Each part of the code affects how the bearing behaves in service.
Typical uses include gearboxes, machine tools, pumps, fans, compressors and power transmission equipment. The bearing handles high radial loads and stays rigid under heavy mechanical demand, so it appears in critical positions in food processing, petrochemical, steel and cement operations. Because the design is separable, maintenance and replacement are easier, which helps shorten downtime.
Selection starts with the internal radial clearance. C4 is intended for running conditions where temperatures are high or thermal expansion must be absorbed. During mounting, use the correct tools and never strike the rollers directly. Lubrication has to match the speed and temperature of the application, and the housings must be aligned precisely to prevent extra loads. Sealing depends on the environment; in contaminated areas, consider bearings with additional seals or shields.
For interchangeability, SKF cylindrical roller bearings can be replaced by equivalents from other recognized brands when dimensions, clearance and cage specifications match. Always check the full designation, because suffixes such as C4 or VA305 can differ between manufacturers and change performance. If you are replacing a bearing, send the complete part number and our team will help you find a suitable option.

Frequently asked questions
- SKF NU 2315 ECML/C4VA305 bearing: what are its dimensions?
- SKF NU 2315 ECML/C4VA305 measures 75 mm across the bore and 160 mm across the outside diameter; its width is 55 mm (75 x 160 x 55 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation NU 2315.
- What does the C4 suffix mean on this bearing?
- C4 indicates an internal radial clearance greater than standard. It is used where operating temperatures are high or thermal expansion needs to be compensated, so the bearing keeps working correctly.
- Is this bearing interchangeable with other brands?
- It can be interchanged with bearings from other brands that share the same dimensions, clearance and cage specifications. Check the complete designation, since suffixes may vary between manufacturers.
- How should I mount this bearing?
- Use suitable tools and avoid direct blows on the rollers. Follow the recommended alignment and lubrication practices to support proper operation and service life.
