Cylindrical Roller Bearings FAG NUP303 -E-XL-TVP2

The FAG NUP303 -E-XL-TVP2 cylindrical roller bearing is a single-row fixed bearing with a 17 mm bore, a 47 mm outer diameter and a low-noise polyamide cage.

This single-row cylindrical roller bearing, the NUP303 -E-XL-TVP2 from FAG, combines a compact design with high radial load-carrying capacity. Thanks to the line contact between the cylindrical rollers and the raceways, the design can withstand high radial forces. The roller bearing has a bore of 17 mm, an outside diameter of 47 mm and a width of 14 mm. Manufactured to standard tolerance (P0/PN or ABEC 1), this version is suitable for standard precision requirements in mechanical engineering and gearbox construction.

What is the NUP303 -E-XL-TVP2 cylindrical roller bearing suitable for in practice?

This design is primarily used in bearing arrangements that must accommodate not only high radial forces but also axial forces. As a fixed bearing, the NUP design guides the shaft in both axial directions, as it features two fixed flanges on the outer ring and one fixed flange and one loose flange disc on the inner ring. Suitable applications include shaft mountings where precise axial guidance on both sides is required.

What are the advantages of the TVP2 polyamide cage in the fixed bearing?

The designation TVP2 indicates a solid, windowed cage made of polyamide, which guides the rolling elements precisely. Compared with metal cages, this material reduces the weight of the rotating parts and ensures quiet operation with lower friction. The open bearing is designed for operating temperatures ranging from -30 to +120 degrees. As the outer ring has no lubrication groove, the lubricant is supplied from the side via the housing.
