Cylindrical Roller Bearings FAG NU313 -E-XL-TVP2-C3

The FAG NU313 -E-XL-TVP2-C3 cylindrical roller bearing, with a 65 mm bore, polyamide cage and C3 clearance, provides a high-load-capacity idler bearing for radial forces.

This single-row cylindrical roller bearing, model NU313 -E-XL-TVP2-C3, is designed as a non-locating bearing. Thanks to the line contact between the rollers and raceways, the design can accommodate high radial loads. This design is manufactured by FAG and has main dimensions of 65 mm inner diameter, 140 mm outer diameter and 33 mm width. As the inner ring has no flanges, it can be removed from either side, which in practice facilitates the separate assembly of the inner and outer rings.

In which applications is the NU313 -E-XL-TVP2-C3 cylindrical roller bearing used as a non-locating bearing?

Design engineers and maintenance personnel primarily use this design where purely radial forces are present and operational changes in shaft length must be compensated for without causing stress. Typical applications can be found in general mechanical engineering as well as in shaft bearings subject to high radial loads. The NU design accommodates linear expansion directly within the bearing. The open bearing, which has no integrated seal, operates in lubricated housings, with a permissible temperature range of –30 to +120 degrees.

What are the advantages of C3 bearing clearance and a polyamide cage in the NU313?

The designation C3 indicates a slightly increased radial clearance compared with the standard clearance. This variant is recommended where temperature differences occur between the shaft and housing, or where tight fits reduce the operating clearance after installation. The TVP2 polyamide cage guides the rolling elements with low vibration and is characterised by its low weight. The bearing complies with tolerance class P0/PN or ABEC 1. When designing the system, it should be noted that the non-locating bearing cannot accommodate axial forces.
