Cylindrical Roller Bearings FAG NJ304 -E-XL-TVP2

The FAG NJ304 -E-XL-TVP2 cylindrical roller bearing, with dimensions of 20x52x15 mm, offers high radial load capacity and single-sided axial guidance.

As a single-row cylindrical roller bearing, the FAG NJ304 -E-XL-TVP2 absorbs very high radial loads. Thanks to the line contact between the rollers and raceways, the design withstands heavy loads. As an open rolling bearing without sealing rings, the bearing assembly can be flexibly integrated into external lubrication systems using oil or grease. The manufacturer, FAG, produces this component in the standard tolerance class P0/PN (ABEC 1) and with standard radial clearance for a wide range of industrial applications.

In which bearing arrangements does the NJ304 -E-XL-TVP2 accommodate radial and axial forces?

This radial roller bearing is used in industrial applications where rigid shaft mountings are required. Thanks to its cylindrical rolling elements, the component retains its dimensional stability even under high loads. The permissible temperature range is from –30 to +120 degrees Celsius. The NJ design acts as a support bearing: in addition to the predominant radial forces, it also absorbs axial guidance forces from one direction, which facilitates the design of compact assemblies.

What are the functions of the NJ design and the 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, which facilitates the separate assembly of both bearing rings. At the same time, the bearing compensates for axial length changes in the shaft in the opposite direction. The suffix TVP2 indicates a polyamide cage. This cage is characterised by its low weight, elastic properties and quiet running.
