Cylindrical Roller Bearings FAG NU2309 -E-XL-TVP2-C3

The single-row FAG cylindrical roller bearing NU2309 -E-XL-TVP2-C3 with a 45 mm bore acts as a separable support bearing for high radial loads in mechanical engineering.

The FAG NU2309 -E-XL-TVP2-C3 cylindrical roller bearing is designed for demanding industrial applications where high radial forces act on the bearing. Thanks to the line contact between the cylindrical rollers and the raceways, the design offers a high radial load-carrying capacity. The integrated polyamide cage ensures smooth guidance of the rolling elements, reduces the weight compared to solid metal cages and promotes smooth running during continuous operation.

In which bearing arrangements does the NU design prove its worth?

This cylindrical roller bearing is primarily used as a non-locating bearing in designs subject to purely radial loads. As the outer ring is fitted with two fixed flanges and the inner ring is flangeless, the design compensates for axial length changes in the shaft directly within the rolling element set. This axial displacement helps to prevent thermal stresses in the bearing seat. As an open rolling bearing without seals, the bearing assembly can be flexibly lubricated with grease or oil.

What are the advantages of the split design and the C3 clearance?

The design with a slightly increased radial clearance (C3) offers additional compensation for temperature differences between the bearing rings as well as for tight fits. The permissible temperature range is from –30 to +120 degrees. A further advantage is the inner ring, which can be removed from both sides: both rings can be fitted separately. The component complies with tolerance class P0/PN or ABEC 1 and has an outer ring without a lubrication groove or lubrication bore.
