Cylindrical Roller Bearings FAG NJ2205 -E-XL-TVP2

The FAG NJ2205 -E-XL-TVP2 cylindrical roller bearing, measuring 25x52x18 mm, offers a compact support bearing solution for high radial loads with axial guidance.

The FAG NJ2205 -E-XL-TVP2 cylindrical roller bearing is a single-row rolling bearing with cylindrical rollers, designed primarily for high radial loads. Thanks to the line contact between the rolling elements and the raceways, this design can accommodate high radial forces. As an open bearing, it can be flexibly integrated into oil- or grease-lubricated machine housings.

What functions does the NJ2205 -E-XL-TVP2 cylindrical roller bearing perform as a support bearing?

Mechanical engineering designs often require a clear allocation of guidance functions. As a support bearing of the NJ design, this roller bearing has two fixed flanges on the outer ring and one fixed flange on the inner ring. As a result, in addition to high radial forces, it also accommodates axial guidance forces from one direction, whilst allowing a defined axial displacement in the opposite direction. This is particularly useful for bearing arrangements where thermal linear expansion of the shaft needs to be compensated for.

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

The polyamide cage (designation TVP2) guides the rollers whilst being lightweight. This reduces inertial forces and supports operation within a temperature range of -30 to +120 degrees. Furthermore, the inner ring can be removed from one side. This simplifies assembly, as the inner and outer rings can be fitted separately. With tolerance class P0 (ABEC 1) and standard radial clearance, this roller bearing meets common industrial requirements.
