Cylindrical Roller Bearings FAG NU2311 -E-XL-TVP2-C3

The FAG NU2311 -E-XL-TVP2-C3 cylindrical roller bearing, with a 55 mm bore, offers high radial load-carrying capacity and axial length compensation when used as a non-locating bearing.

The NU2311 -E-XL-TVP2-C3 cylindrical roller bearing is a single-row radial roller bearing designed for demanding industrial applications. With an inner diameter of 55 mm, an outer diameter of 120 mm and a width of 43 mm, the design can withstand very high radial forces. Designed as an open bearing, it can be flexibly integrated into existing lubrication systems and is designed for continuous operation in mechanical engineering.

In which installation scenarios is the NU2311 -E-XL-TVP2-C3 support bearing used?

This cylindrical roller bearing is primarily used in bearing arrangements where high radial loads are present and axial displacement of the shaft must be compensated for. Typical applications include shaft mountings subject to operational thermal expansion. Thanks to the line contact between the rollers and raceways, the bearing can also withstand heavy impact loads. As the inner ring can be removed from both sides, the unit functions purely as a non-locating bearing and prevents unwanted forced forces within the bearing assembly.

What do C3 bearing clearance and the polyamide cage mean for operation?

This design features a slightly increased radial clearance (C3). This increased clearance between the rollers and raceways prevents jamming when temperature differences occur between the inner and outer rings or when tight fits reduce the radial clearance. The integrated polyamide cage ensures quiet roller guidance and reduces weight compared with metal designs. Together with manufacture to standard tolerance P0, the component covers a permissible operating temperature range of –30 to +120 degrees Celsius.
