Cylindrical Roller Bearings FAG NU2308 -E-XL-TVP2-C3

The FAG NU2308 -E-XL-TVP2-C3 cylindrical roller bearing, measuring 40x90x33 mm, serves as a single-row support bearing designed to accommodate high radial loads.

The NU2308 -E-XL-TVP2-C3 cylindrical roller bearing is a single-row rolling bearing manufactured by FAG Wälzlager. The design features solid 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 assembly of both bearing rings. As an open cylindrical roller bearing without an integrated seal, this design is intended for use in oil- or grease-lubricated housings.

When is the NU2308 -E-XL-TVP2-C3 cylindrical roller bearing suitable as a non-locating bearing?

In shaft mountings, this design accommodates purely radial loads and compensates for axial changes in shaft length directly within the bearing. As the rollers can slide axially on the cylindrical raceway of the inner ring, no internal stresses arise during thermal expansion. The bearing is primarily used in bearing arrangements where a clearly defined floating bearing function is required. The line contact between the rollers and the raceway ensures a high radial load-carrying capacity under heavy radial loads.

What is the function of the TVP2 cage and the C3 clearance?

The designation TVP2 stands for a polyamide window cage, which guides the cylindrical rollers securely and reduces the bearing weight. Thanks to the elastic behaviour of the plastic, the bearing runs quietly and can withstand rapid changes in speed. The version with bearing clearance class C3 has a slightly increased radial clearance compared with standard clearance. This clearance prevents the rolling elements from becoming jammed if operational heating or tight fits cause the inner ring to expand.
