Cylindrical Roller Bearings FAG NU303 -E-XL-TVP2

The FAG NU303 -E-XL-TVP2 cylindrical roller bearing with a 17 mm bore accommodates high radial loads and allows for axial length compensation.

The FAG NU303 -E-XL-TVP2 cylindrical roller bearing is designed as a single-row rolling bearing for industrial applications involving high radial loads. Thanks to the line contact between the cylindrical rollers and the raceway, the design can withstand high radial forces. With standardised key dimensions of a 17 mm bore, 47 mm outer diameter and 14 mm width, this roller bearing can be fitted in space-saving, precisely matched bearing arrangements.

In which applications is the NU303 -E-XL-TVP2 cylindrical roller bearing used?

As a non-locating bearing, this design absorbs purely radial forces and compensates for axial shaft displacement directly within the rolling bearing. Typical applications are found in general mechanical engineering and in industrial powertrains where shafts expand as a result of operational heating. As the outer ring has two fixed flanges, whilst the inner ring is flangeless, the shaft moves relative to the housing without causing harmful stresses in the bearing seat.

What is the function of the NU design with a polyamide cage?

The designation ‘NU’ indicates that the inner ring can be removed from both sides. This feature simplifies assembly and maintenance processes, as both rings can be press-fitted onto the shaft and housing independently of one another. The integrated polyamide cage guides the roller elements with low friction and contributes to quiet running. The open bearing is designed for a temperature range of -30 to +120 degrees and requires an appropriate lubricant supply via the housing.
