Cylindrical Roller Bearings FAG NU218 -E-XL-TVP2-C3

The FAG NU218 -E-XL-TVP2-C3 single-row cylindrical roller bearing, with dimensions of 90 × 160 × 30 mm, accommodates high radial forces as a non-locating bearing.

The NU218 -E-XL-TVP2-C3 cylindrical roller bearing is an open rolling bearing with a cylindrical bore. The NU design is characterised by two fixed flanges on the outer ring, whilst the inner ring is flangeless. This allows the inner ring to be removed from both sides, which facilitates the separate mounting of the inner and outer rings onto the housing and shaft. The design is intended to transmit high radial loads with the standard tolerance class P0/PN.

In which assemblies is the NU218 -E-XL-TVP2-C3 cylindrical roller bearing used?

This idler bearing is designed to accommodate purely radial forces and compensates for axial changes in shaft length directly within the bearing without inducing stress. Typical applications are found in general mechanical engineering for shaft mountings subject to high radial loads. Thanks to the line contact between the rollers and raceways, the design can withstand high radial loads. For axial guidance of the shaft, the floating bearing is usually combined with a separate fixed bearing.

What are the functions of the C3 radial clearance and the polyamide cage?

The version with C3 bearing clearance has greater radial clearance than a bearing with standard clearance. This radial clearance serves to compensate for thermal expansion during operation or for radial constrictions caused by tight fits. The TVP2 polyamide cage guides the rollers quietly and reduces the weight of the moving parts. For operation, the permissible temperature range of -30 to +120 degrees must be observed. As there are no integrated seals, lubrication is provided via the surrounding housing structure.
