Cylindrical Roller Bearings FAG NU319 -E-XL-TVP2-C3

The FAG NU319 -E-XL-TVP2-C3 single-row cylindrical roller bearing with a 95 mm bore accommodates high radial loads as a separable idler bearing.

This NU319 -E-XL-TVP2-C3 cylindrical roller bearing is designed as an open, single-row radial roller bearing for demanding industrial applications. Thanks to the line contact between the rolling elements and raceways, the design withstands high radial forces whilst maintaining high structural rigidity. The bearing has an outer diameter of 200 mm and a width of 45 mm, and complies with tolerance classes P0/PN and ABEC 1 respectively.

In which mounting configurations is the NU319 -E-XL-TVP2-C3 idler bearing used?

The NU design serves as a non-locating bearing. As the inner ring has no flanges, it can be removed from either side and compensates for axial length changes of the shaft relative to the housing within the bearing. Typical applications include bearing arrangements in mechanical engineering where high radial forces must be accommodated. The separate assembly of the inner and outer rings facilitates installation in confined spaces.

What is the function of the C3 bearing clearance and the polyamide cage?

This design features a slightly increased radial clearance (C3). This increased clearance between the rollers and raceways compensates for thermal expansion caused by heat build-up during operation, thereby preventing radial stress. The integrated polyamide cage (TVP2) guides the cylindrical rollers quietly and is characterised by its low weight. The open bearing is designed for a temperature range of -30 to +120 degrees and requires an external lubricant supply as well as sealing in the adjacent structure.
