Cylindrical Roller Bearings FAG NU304 -E-XL-TVP2-C3

The FAG NU304 -E-XL-TVP2-C3 cylindrical roller bearing (20x52x15 mm) serves as a separable idler bearing for high radial loads at operating temperatures ranging from -30 to +120 °C.

The single-row cylindrical roller bearing NU304 -E-XL-TVP2-C3 from FAG, as a radial roller bearing, accommodates high radial loads. With a bore of 20 mm, an outer diameter of 52 mm and a width of 15 mm, this design complies with tolerance class P0/PN or ABEC 1. The rollers and outer ring form a fixed unit, whilst the inner ring remains removable on both sides. This floating bearing design allows for the unrestricted compensation of thermal length changes directly within the bearing assembly.

When is the NU304 -E-XL-TVP2-C3 cylindrical roller bearing used?

Design engineers and maintenance personnel primarily use this design where purely radial loads prevail and axial displacement of the shaft relative to the housing needs to be compensated for. Typical applications include bearing arrangements subject to operational shaft expansion. As the inner ring has no flanges, this component does not absorb any axial forces. The open design requires that the installation point be protected from contamination by an external seal and that suitable lubrication is provided.

What are the advantages of a polyamide cage and C3 clearance?

The suffixes denote specific technical features for demanding environments. The TVP2 polyamide cage is characterised by its low weight and elastic properties, which contribute to smooth running. In combination with the slightly increased radial bearing clearance (C3), rotational freedom is maintained even when operational heating or tight fits reduce the radial clearance. The operating temperature range is specified as -30 to +120 degrees, which corresponds to the properties of the cage material.
