Decoding SKF NUP 307 ECP/C4VB006
- NUP 3Series
- Cylindrical roller bearings, NUP 3 series. Series differ in outside diameter and width even when the bore is the same.
- 07Bore
- Bore 35 mm (07 × 5).
- ECP/C4VB006Suffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
NUP 307 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF NUP 307 ECP/C4VB006 measures 35 mm across the bore and 80 mm across the outside diameter; its width is 21 mm (35 x 80 x 21 mm).

For maintenance and purchasing teams working with gear reducers, pumps, compressors, or process equipment, the SKF NUP ECP/C4VB006 cylindrical roller bearing is a solid option when you need high radial capacity and controlled axial movement. Its design combines a double-flanged inner ring with an outer ring that has one flange and one flat face, and it uses a glass fibre reinforced polyamide cage. MR Industrial Accessories LLC supplies this bearing as part of its SKF range for customers throughout the United States and Latin America.
The code NUP 307 ECP/C4VB006 breaks down as follows: NUP identifies the bearing type, 307 gives the bore diameter and dimension series, ECP points to the polyamide cage with optimized geometry, C4 means internal radial clearance is greater than standard, and VB006 is a specific manufacturing variant. This combination is often chosen for interference fits or elevated operating temperatures, where extra clearance helps compensate for thermal expansion.
Typical uses include gear reducers, centrifugal pumps, compressors, machine tools, and power transmission equipment. The flanged inner ring allows axial location in both directions, so the bearing can handle moderate axial loads alongside high radial loads. Industries such as food processing, petrochemical, steel, and cement rely on this type of bearing in demanding environments where reliability matters.
When selecting a replacement, review the radial and axial loads, rotational speed, and ambient conditions. Confirm that the C4 clearance suits your fit and temperature. During mounting, align shaft and housing carefully and use the recommended heating or pressing method to avoid damage. Follow the manufacturer’s lubrication guidance, and add seals or shields if contamination is a concern.
Interchangeability with other brands is possible when the dimensional designation and internal clearance match, but tolerances and load ratings can differ. Always check technical tables and validate the alternative before installation. If you need help, send the complete part number and our team can suggest equivalents and assist with selection.

Frequently asked questions
- SKF NUP 307 ECP/C4VB006 bearing: what are its dimensions?
- SKF NUP 307 ECP/C4VB006 measures 35 mm across the bore and 80 mm across the outside diameter; its width is 21 mm (35 x 80 x 21 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation NUP 307.
- What does the C4 suffix indicate on this bearing?
- C4 denotes an internal radial clearance larger than standard. It is used when interference fits or high operating temperatures would otherwise reduce the clearance during operation.
- Does the NUP ECP/C4VB006 include seals?
- No, the standard designation does not include seals. If you need protection from contaminants, ask about sealed or shielded variants, or plan to use external oil seals in the assembly.
- Can I use another brand as a replacement?
- Yes, provided the dimensional designation and internal clearance are the same. Verify tolerances and load capacities of the alternative. Contact us with the original part number and we will help you confirm the correct replacement.
