Cylindrical Roller Bearings FAG NU314 -E-XL-M1-C3

The single-row cylindrical roller bearing NU314 -E-XL-M1-C3 from FAG Wälzlager, with dimensions of 70x150x35 mm, accommodates high radial forces as a separable support bearing.

The NU314 -E-XL-M1-C3 cylindrical roller bearing functions as a single-row radial roller bearing for demanding industrial applications. In the NU design, the bearing has two fixed flanges on the outer ring, whilst the inner ring is flangeless. This allows the inner ring to be removed from both sides, enabling the shaft and housing to be fitted separately. FAG Rolling Bearings equips this model ex works with a solid brass cage and an increased radial clearance of C3.

In which bearing arrangements is the NU314 -E-XL-M1-C3 non-locating bearing used?

This rolling bearing is primarily used as a non-locating bearing in shaft guides subject to high radial loads. Thanks to the flangeless design of the inner ring, the bearing compensates for axial changes in shaft length caused by thermal expansion without any constraint within the bearing. It is used in applications where high transverse forces act on the 70 mm shaft and precise guidance of the rollers without additional axial force support is required.

How do the brass cage and increased C3 clearance affect performance during operation?

The solid brass cage (M1) guides the cylindrical rollers stably under vibrations and high dynamic acceleration forces. In combination with the slightly increased C3 bearing clearance, the bearing remains operational when temperature differences occur between the inner and outer rings during operation, or when tight fits reduce the internal clearance. As this is an open bearing without an integrated seal, lubrication is provided by the surrounding housing system within a temperature range of -30 to +150 degrees.
