Cylindrical Roller Bearings FAG NU220 -E-XL-M1-C3

The FAG nu220-e-m1-c3 cylindrical roller bearing withstands high radial loads and offers thermal stability thanks to its brass cage and increased bearing clearance.

The nu220-e-m1-c3 cylindrical roller bearing is a radial rolling bearing from FAG for demanding industrial applications. In the NU design, the outer ring guides the rollers between two fixed flanges, whilst the inner ring is flangeless. This design allows for unrestricted axial movement of the shaft relative to the housing. As an open rolling bearing without integrated sealing washers, the bearing is designed to be lubricated via the surrounding structure.

What is the NU220-E-M1-C3 cylindrical roller bearing suitable for?

This bearing design is primarily used as a floating bearing arrangement under high radial loads to compensate for thermal length changes in the shaft. Typical applications are found in general mechanical and plant engineering for shaft mountings subject to purely radial loads. As the outer ring, together with the set of rollers, can be separated from the inner ring, the bearing can be fitted in stages even where space is limited. The cylindrical bore ensures a tight fit on cylindrical shaft journals.

What are the advantages of a brass cage and C3 clearance?

The designation M1 indicates a robust, solid brass cage that precisely guides the cylindrical rollers. Brass cages are particularly recommended for applications involving severe vibrations, high accelerations and elevated operating temperatures. This design is complemented by bearing clearance class C3, which describes a slightly increased radial bearing clearance. This increased operating clearance compensates for dimensional changes caused by temperature variations or tight fits, thereby reducing the risk of the rolling elements becoming jammed.
