Cylindrical Roller Bearings FAG NU2214 -E-XL-TVP2-C3

The FAG NU2214 -E-XL-TVP2-C3 cylindrical roller bearing, measuring 70x125x31 mm with a C3 clearance and a polyamide cage, offers a high radial load capacity as a separable non-locating bearing.

The NU2214 -E-XL-TVP2-C3 cylindrical roller bearing is a single-row radial roller bearing from FAG. With dimensions of 70 mm bore, 125 mm outer diameter and 31 mm width, this design can withstand high radial loads. The cylindrical rollers create line contact with the raceway, ensuring high radial rigidity. This open bearing is designed for operating temperatures ranging from –30 to +120 degrees.

When is the NU2214 -E-XL-TVP2-C3 cylindrical roller bearing suitable as a non-locating bearing?

As a non-locating bearing of the NU design, this model has two fixed flanges on the outer ring, whilst the inner ring is flangeless and can be removed from either side. Designs make specific use of this feature to compensate for axial length changes in the shaft caused by heating, without restricting movement within the bearing housing. Typical applications are found in general mechanical engineering in bearing arrangements where high radial forces occur and the design is intended to prevent axial stresses.

What advantages do the TVP2 cage and the C3 clearance offer?

The TVP2 polyamide cage guides the rollers with low mass, which contributes to smooth running and reduces inertial forces during changes in speed. The C3 designation indicates an increased radial clearance compared with the standard version. This clearance compensates for dimensional changes when temperature differences arise between the inner and outer rings during operation, or when tight fits are selected. The open bearing complies with tolerance class P0 or ABEC 1.
