Cylindrical Roller Bearings FAG NU209 -E-XL-TVP2-C3

The FAG NU209 -E-XL-TVP2-C3 cylindrical roller bearing offers high radial load capacity with a 45 mm bore, 85 mm outer diameter and 19 mm width.

This single-row cylindrical roller bearing, NU209 -E-XL-TVP2-C3, is designed as a free bearing only. The inner ring has no flanges and can be removed from either side, allowing the bearing to compensate axially for changes in shaft length caused by thermal expansion. This design is from FAG and complies with tolerance class P0/PN or ABEC 1. It is primarily suitable for bearing arrangements subject to high radial loads where no axial forces need to be transmitted.

In which bearing arrangements is the NU209 -E-XL-TVP2-C3 cylindrical roller bearing used?

The rolling bearing primarily absorbs radial loads and supports shafts with purely radial force application. Due to its NU design, the bearing supports the shaft purely radially and allows axial displacement between the shaft and housing in both directions. The line contact of the cylindrical rollers contributes to high rigidity. As the bearing is of an open design, the surrounding structure requires a suitable lubrication system as well as an external housing seal to protect against dirt and moisture.

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

The suffixes provide information about specific design features: the polyamide cage (TVP2) guides the rollers quietly and is characterised by its low weight. The designation C3 indicates a slightly increased radial clearance compared with the standard version. This increased clearance between the rollers and raceways compensates for fit allowances during installation and heat build-up during operation, without the rolling elements becoming stressed. The permissible temperature range is from -30 to +120 degrees Celsius.
