Cylindrical Roller Bearings FAG NUP2218 -E-XL-TVP2-C3

The FAG NUP2218 -E-XL-TVP2-C3 cylindrical roller bearing is a single-row fixed bearing with a 90 mm bore, designed for high radial loads and axial guidance on both sides.

As a single-row roller bearing, the NUP2218 -E-XL-TVP2-C3 can accommodate very high radial forces. Thanks to the NUP design, the bearing acts as a fixed bearing that guides shafts in both axial directions. This version features two fixed flanges on the outer ring, as well as one fixed flange and one loose flange disc on the inner ring. FAG manufactures this model as an open bearing for operating temperatures ranging from –30 to +120 degrees Celsius.

What is the NUP2218 -E-XL-TVP2-C3 cylindrical roller bearing suitable for in operation?

Design engineers use this design when assemblies require precise axial positioning of the shaft under high radial loads. Typical applications include gearboxes and industrial drive units subject to combined loads. The line contact of the cylindrical rollers ensures high rigidity of the bearing arrangement. As the NUP design provides guidance in both axial directions, there is no need for an additional axial bearing on the shaft, which simplifies the design of the bearing arrangement.

What are the advantages of the polyamide cage and the C3 clearance?

The suffix TVP2 denotes a lightweight polyamide cage. This cage material is characterised by favourable damping properties and smooth running. The increased radial clearance (C3) compensates for operational temperature variations and tight fits between the shaft and housing without causing stress. Tolerance class P0 meets the standard accuracy requirements for fitted seats in mechanical engineering.
