Cylindrical Roller Bearings FAG NJ320 -E-XL-TVP2

The FAG NJ320 -E-XL-TVP2 single-row cylindrical roller bearing, measuring 100 × 215 × 47 mm, serves as a support bearing for heavy radial loads.

This NJ320 -E-XL-TVP2 cylindrical roller bearing is designed as an open, single-row radial roller bearing for demanding industrial applications. The line contact of the cylindrical rollers absorbs high radial forces, whilst the NJ design simultaneously supports axial guidance forces from one direction. The component has the standard tolerance class P0 (ABEC 1) and normal radial clearance. FAG manufactures this bearing without a groove or lubrication bore in the outer ring.

What is the NJ320 -E-XL-TVP2 cylindrical roller bearing suitable for?

The NJ design is particularly suitable for bearing arrangements subject to high radial forces and single-sided axial guidance of the shaft. As a support bearing, this design allows the shaft to be fixed axially on one side, whilst freely compensating for thermally induced length changes in the opposite direction. The polyamide cage ensures smooth running at varying speeds and guides the rollers within the rolling element set.

What is the function of the NJ design with a polyamide cage?

The NJ design features two fixed flanges on the outer ring and one fixed flange on the inner ring. This allows the inner ring to be removed from one side for assembly and fitted separately onto the shaft. The TVP2 polyamide cage guides the cylindrical rolling elements and retains its dimensional stability within a temperature range of -30 to +120 degrees. As this is an open roller bearing, the lubricant and external housing seals are selected to suit the specific application.
