Cylindrical Roller Bearings FAG NU316 -E-XL-TVP2

The NU316 -E-XL-TVP2 cylindrical roller bearing from FAG Wälzlager, with main dimensions of 80 × 170 × 39 mm, withstands high radial loads during operation.

The NU316 -E-XL-TVP2 cylindrical roller bearing is a single-row roller bearing from FAG Wälzlager designed for industrial applications involving predominantly radial loads. With a bore of 80 mm, an outside diameter of 170 mm and a width of 39 mm, the design is capable of withstanding high loads. As the inner ring is manufactured without a flange, the NU design acts as a non-locating bearing. This allows for axial displacement of the shaft relative to the housing directly within the bearing.

Where is the NU316 -E-XL-TVP2 cylindrical roller bearing used as a floating bearing?

This bearing design is primarily used in bearing arrangements in general mechanical and plant engineering where thermal length changes in the shaft need to be compensated for. Thanks to the free-end bearing function, no impermissible axial stresses occur even when the bearing heats up. As the rolling bearing is of open design, the lubricant can circulate unhindered. The external design of the bearing housing ensures protection against dirt and moisture.

What are the advantages of the polyamide cage and the NU design?

The polyamide (TVP2) cage guides the cylindrical rollers precisely and is characterised by its low weight and low-vibration operation. The design covers a temperature range from –30 to +120 degrees. Furthermore, the design offers significant assembly advantages: as the inner ring can be removed from both sides, the inner and outer rings can be fitted separately onto the shaft and into the housing, which makes installation and inspection considerably easier.
