Cylindrical Roller Bearings FAG NU318 -E-XL-TVP2

The FAG NU318 -E-XL-TVP2 cylindrical roller bearing, measuring 90 × 190 × 43 mm, is an open idler bearing designed to withstand high radial loads.

This single-row NU318 -E-XL-TVP2 cylindrical roller bearing from FAG is primarily designed to accommodate high radial loads. Thanks to the line contact of the cylindrical rollers, the bearing offers high rigidity during operation. This open bearing has a bore of 90 mm, an outside diameter of 190 mm and a width of 43 mm. As it has no integrated seals, lubricant can be applied directly from the outside.

What is the NU318 -E-XL-TVP2 cylindrical roller bearing suitable for?

This cylindrical roller bearing is particularly suitable for bearing arrangements subject to high radial loads. As a floating bearing, the design compensates for axial length changes resulting from operating temperatures. The cylindrical rollers move freely along the flangeless raceway of the inner ring. This allows axial displacement to occur within the bearing without stress, without additional axial forces acting on adjacent components.

What are the distinctive features of the NU design and the TVP2 cage?

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 assembly of the shaft and bearing housing. The integrated polyamide cage (TVP2) guides the rollers quietly and is characterised by low inertial forces. The roller bearing is designed for use within a temperature range of -30 to +120 degrees.
