Cylindrical Roller Bearings FAG NU2318 -E-XL-TVP2-C3

The FAG NU2318 -E-XL-TVP2-C3 cylindrical roller bearing is a single-row non-locating bearing with a 90 mm bore, designed for high radial loads.

As a single-row roller bearing, the FAG NU2318 -E-XL-TVP2-C3 cylindrical roller bearing can accommodate very heavy radial loads. Thanks to the cylindrical rolling elements, the design provides line contact, which enables high radial stiffness compared to ball bearings. The NU design functions purely as a non-locating bearing: two fixed flanges on the outer ring guide the roller set, whilst the flangeless inner ring remains removable from both sides. This allows for axial displacement of the shaft directly within the bearing.

In which bearing arrangements does the NU2318 -E-XL-TVP2-C3 cylindrical roller bearing prove its worth?

This design is used in bearing arrangements where high radial forces are present and thermally induced changes in the shaft’s length must be compensated for. Thanks to the inner ring, which can be removed from both sides, the bearing compensates for such expansion with low friction internally. As this is an open bearing without a seal, the bearing assembly is lubricated externally with oil or grease and protected from contamination by the housing.

What are the distinctive features of the polyamide cage and the C3 bearing clearance?

The bearing features a polyamide cage, which ensures quiet operation and reduces the weight of the rolling element assembly. The C3 designation indicates a slightly increased radial clearance compared with the standard version. This additional clearance prevents the rolling elements from becoming stressed when temperature differences occur between the shaft and the housing under operating conditions, or when tight fits are selected. The permissible temperature range is from -30 to +120 degrees Celsius.
