Cylindrical Roller Bearings FAG NJ224 -E-XL-TVP2

The FAG NJ224 -E-XL-TVP2 cylindrical roller bearing, with a 120 mm bore, can accommodate high radial loads as well as axial forces in one direction.

The NJ224 -E-XL-TVP2 cylindrical roller bearing is a single-row radial roller bearing from the FAG range. With key dimensions of 120 mm bore diameter, 215 mm outer diameter and 40 mm overall width, this design is suitable for heavy-duty industrial shaft mountings. Thanks to the line contact between the rollers and raceways, the bearing reliably absorbs high radial forces. As an open design without an integrated seal, the roller bearing is designed to be lubricated via the surrounding bearing housing.

How does the NJ224 -E-XL-TVP2 cylindrical roller bearing accommodate radial and axial forces?

This cylindrical roller bearing is used in designs where high radial forces and single-sided axial forces occur. In the NJ version, the bearing acts as a support bearing. It accommodates radial loads as well as axial forces from one direction, as the inner ring is removable from one side and features a fixed flange. In the opposite axial direction, the bearing design allows for axial displacement, enabling changes in shaft length to be compensated for without inducing constraint forces.

What is the function of the polyamide cage and the support bearing design?

The suffix TVP2 denotes a version with a polyamide cage. This cage material reduces the weight of the rotating components and dampens vibrations during operation. The permissible temperature range is between –30 and +120 degrees Celsius. Manufactured to tolerance class P0/PN or ABEC 1 and with standard radial bearing clearance, the bearing can be precisely fitted into housings and onto shafts. As the outer ring is designed without a lubrication bore or groove, the lubricant is supplied via the surrounding structure.
