Cylindrical Roller Bearings FAG NU308 -E-XL-TVP2-C3

The FAG NU308 -E-XL-TVP2-C3 cylindrical roller bearing (40x90x23 mm) withstands high radial loads and compensates for axial length changes when used as a non-locating bearing.

The NU308 -E-XL-TVP2-C3 cylindrical roller bearing is a single-row radial roller bearing from FAG with the main dimensions of a 40 mm bore, 90 mm outer diameter and 23 mm width. As an open bearing, it does not require integrated seals, allowing the component to be flexibly integrated into oil- or grease-lubricated systems. Thanks to the line contact between the cylindrical rollers and the raceways, this bearing can withstand high radial forces. The dimensionally stable polyamide cage guides the rolling elements precisely and quietly.

In which arrangements does the NU308 cylindrical roller bearing act as a non-locating bearing?

This cylindrical roller bearing is primarily used in bearing arrangements where purely radial forces are absorbed and axial displacement occurs. As a non-locating bearing of the NU design, the bearing has two fixed flanges on the outer ring, whilst the inner ring is flangeless. This allows the shaft to move freely within the bearing during thermal expansion, without generating axial stresses in the housing.

What are the advantages of the separable inner ring and the C3 clearance?

The inner ring, which can be removed from both sides, facilitates assembly, as the inner and outer rings can be pressed onto the shaft and housing separately. The designation C3 indicates a slightly increased radial clearance. This clearance prevents the bearing from seizing up due to operational heating or tight fits. Please note that the permissible temperature range for the polyamide cage is from -30 to +120 degrees.
