Cylindrical Roller Bearings FAG NJ221 -E-XL-TVP2

The FAG NJ221 -E-XL-TVP2 cylindrical roller bearing offers high radial load-carrying capacity with dimensions of 105 × 190 × 36 mm and is used as a support bearing.

The FAG NJ221 -E-XL-TVP2 cylindrical roller bearing is a single-row radial roller bearing designed for demanding industrial applications involving high radial forces. With an inside diameter of 105 mm, an outside diameter of 190 mm and a width of 36 mm, this open bearing safely handles high loads. Thanks to the polyamide material in the cage, the unit operates quietly and dampens vibrations. The design complies with the standard tolerance class P0 (ABEC 1) and has standard radial clearance for normal operating temperatures between –30 and +120 °C.

What applications does the NJ design serve as a support bearing?

This single-row cylindrical roller bearing is primarily used where heavy radial loads act on rotating shafts. The NJ design features two fixed flanges on the outer ring and one fixed flange on the inner ring. As a result, the bearing assembly absorbs radial loads and also guides the shaft axially in one direction. Designs utilise this support bearing function to compensate for changes in the shaft’s length whilst simultaneously absorbing unilateral guiding forces.

What are the advantages of a polyamide cage and a separable design?

The integrated polyamide cage (TVP2) is characterised by its low weight and good damping properties, which reduce friction and heat generation. As the inner ring can be removed from one side, the bearing can be fitted separately onto the shaft and housing. This facilitates maintenance and overhaul work. As an open component without an integrated seal and without a lubrication groove in the outer ring, the bearing location requires a clean installation environment as well as an external supply of lubricant, such as grease or lubricating oil, within the specified temperature range.
