Cylindrical Roller Bearings FAG NJ219 -E-XL-TVP2

The FAG NJ219 -E-XL-TVP2 cylindrical roller bearing, with dimensions of 95 × 170 × 32 mm, offers high radial load-carrying capacity and acts as a support bearing with an axial guidance function.

The NJ219 -E-XL-TVP2 cylindrical roller bearing is a single-row radial roller bearing from FAG designed for heavy industrial loads. Thanks to the line contact of the cylindrical rollers, this bearing design can withstand significant radial forces. The manufacturer produces the bearing with a bore diameter of 95 mm, an outer diameter of 170 mm and a width of 32 mm. The NJ design features two fixed flanges on the outer ring and one fixed flange on the inner ring, enabling the bearing to accommodate axial forces in one direction.

In which installation scenarios does the NJ219 cylindrical roller bearing absorb axial and radial forces?

This cylindrical roller bearing is used in bearing arrangements where strong transverse forces act on the shaft and, at the same time, defined axial guidance is required. As a support bearing, the component guides the shaft axially on one side, whilst allowing for changes in length in the opposite direction within the bearing. As the outer ring is designed without a groove or lubrication bore, this open bearing is suitable for designs where lubrication is supplied via the housing or through circulating oil or grease.

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

The designation TVP2 refers to a polyamide window cage, which ensures smooth running and reduces the weight of the rotating components. This cage variant is designed for an operating temperature range of -30 to +120 degrees. A key practical advantage of the NJ design is its ease of disassembly: the inner ring can be removed from one side. This simplifies the separate mounting of the inner and outer rings onto the shaft and housing, as well as subsequent maintenance of the bearing assembly.
