Cylindrical Roller Bearings FAG NJ2218 -E-XL-TVP2

The FAG NJ2218 -E-XL-TVP2 cylindrical roller bearing, with dimensions of 90 × 160 × 40 mm, offers high radial load-carrying capacity and axial guidance in one direction.

This single-row cylindrical roller bearing, model NJ2218 -E-XL-TVP2, manufactured by FAG, acts as a support bearing and absorbs high radial loads. Thanks to the flange configuration on the inner and outer rings, the bearing also guides the shaft in one axial direction. With a bore diameter of 90 mm, an outer diameter of 160 mm and a width of 40 mm, the roller bearing complies with tolerance class P0/PN (ABEC 1). The component has standard radial clearance and operates within a temperature range of -30 to +120 degrees.

What loads can the NJ2218 -E-XL-TVP2 cylindrical roller bearing withstand?

This design is used in bearing arrangements where high radial forces are present and defined axial guidance is required. The NJ design acts as a support bearing: it allows axial displacement in one direction, whilst the fixed ring absorbs axial forces from the opposite direction. As the inner ring can be removed from one side, the bearing can be pressed onto the shaft and housing separately during assembly. This simplifies installation and any necessary maintenance work.

What is the function of the polyamide cage in the cylindrical roller bearing?

The suffix TVP2 denotes a solid polyamide cage that guides the rollers. This cage is characterised by its low weight, which reduces inertial forces during rapid changes in speed. In addition, the plastic dampens vibrations and contributes to the smooth running of the cylindrical rollers. As this is an open bearing without an integrated seal, lubrication is supplied via the housing. The outer ring is designed without a groove or lubrication bore.
