Decoding SKF NUP 308 ECP/VB498
- NUP 3Series
- Cylindrical roller bearings, NUP 3 series. Series differ in outside diameter and width even when the bore is the same.
- 08Bore
- Bore 40 mm (08 × 5).
- ECP/VB498Suffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
NUP 308 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description

The SKF NUP 308 ECP/VB498 is a cylindrical roller bearing from the NUP ECP line, built to carry high radial loads while guiding the shaft axially in both directions. Its two-row roller arrangement and stamped steel cage suit continuous duty in industrial machinery. MR Industrial Accessories supplies this bearing as part of its SKF range for plants across the US, Canada, Mexico and South America.
Reading the code tells you most of what you need. NUP describes the ring geometry: two ribs on the inner ring and one on the outer ring, so the bearing locates the shaft axially in either direction. ECP points to a glass fibre reinforced polyamide cage, window type, roller centred, in standard execution. The VB element followed by a number, as in NUP 308 ECP/VB498, marks a specific manufacturing variant, usually tied to particular tolerances or internal clearances. Confirm the exact meaning of that variant against the manufacturer's data sheet before ordering.
Typical duties include gearboxes, machine tools, pumps, compressors, electric motors and power transmission equipment. The combination of high radial load capacity and moderate speed capability fits demanding environments, and the food, cement, steel and mining sectors commonly run these bearings on their lines.
Sizing the bearing starts with the radial and axial loads, the rotational speed, the lubrication method and the surrounding conditions. Because NUP bearings provide axial guidance, mounting calls for precise alignment and correct fits on both shaft and housing. Grease or oil both work, depending on the application, and the sealing choice follows the level of contamination present. Following the manufacturer's instructions supports reliable running and long service life.
On interchangeability, NUP-design cylindrical roller bearings follow a standardized designation, so equivalents from other recognized makers may fit, provided dimensions and load capacity are checked. Tolerances and axial clearance can differ between brands, so it is worth having a specialist validate the specifications before you swap one for another.
