Cylindrical Roller Bearings FAG NU2209 -E-XL-TVP2-C3

The FAG NU2209 -E-XL-TVP2-C3 cylindrical roller bearing offers high radial load-carrying capacity with dimensions of 45x85x23 mm and, as a floating bearing, compensates for axial length changes.

The FAG NU2209 -E-XL-TVP2-C3 cylindrical roller bearing is a single-row radial roller bearing for industrial applications involving high radial loads. In the NU design, the outer ring has two fixed flanges, whilst the inner ring is flangeless. This allows the inner ring to be removed from both sides, which facilitates the separate installation of both bearing rings. Designed as an open bearing, this component requires an external lubricant supply and a housing seal.

In which applications is the NU2209 -E-XL-TVP2-C3 cylindrical roller bearing used as a floating bearing?

This radial roller bearing is primarily used in idler bearing positions where thermal linear expansion of the shaft must be compensated for without constraint. Due to the line contact between the rollers and raceways, the design can withstand high radial forces. Typical applications are found in general industrial and mechanical engineering where a load-bearing guide in the radial direction is required whilst allowing for axial displacement.

What advantages do the polyamide cage and C3 bearing clearance offer?

The TVP2 design features a solid polyamide cage, which ensures smooth running and reduces the weight of the bearing assembly. The slightly increased radial clearance (C3) provides additional leeway in the event of heating during operation or where there are tight fits between the shaft and housing. In combination with tolerance class P0/PN or ABEC 1 and an operating temperature range of -30 to +120 degrees, the rolling bearing retains its dimensional stability even under fluctuating thermal conditions.
