Cylindrical Roller Bearings FAG NUP311 -E-XL-TVP2

The FAG NUP311 -E-XL-TVP2 single-row cylindrical roller bearing supports shafts with a 55 mm bore axially on both sides and withstands high radial loads.

This single-row radial roller bearing from FAG is designed for industrial applications. With key dimensions of a 55 mm bore, 120 mm outer diameter and 29 mm width, the NUP311 -E-XL-TVP2 cylindrical roller bearing combines a high radial load-carrying capacity with a compact design. The outer ring has no groove or lubrication bore. As an open component, the bearing can be integrated directly into existing lubrication systems using oil or grease.

What loads can the NUP311 -E-XL-TVP2 cylindrical roller bearing withstand as a fixed bearing?

This design is suitable for bearing arrangements where, in addition to high radial loads, axial guiding forces occur in both directions. As a fixed bearing, the component accommodates axial displacement of the shaft and guides the shaft axially within the housing. Thanks to its permissible temperature range of –30 to +120 degrees, the roller bearing retains its dimensional stability during operation even in the face of thermal fluctuations.

What are the functions of the NUP design and the TVP2 polyamide cage?

The NUP design is characterised by two fixed flanges on the outer ring and one fixed flange and one loose flange disc on the inner ring. This arrangement enables axial fixation on both sides whilst allowing for straightforward assembly of the separate rings. The integrated polyamide cage (TVP2) guides the cylindrical rolling elements with low frictional resistance. Together with tolerance class P0/PN (ABEC 1) and standard radial clearance, this design contributes to smooth running.
