Cylindrical Roller Bearings FAG NJ2219 -E-XL-TVP2

The FAG NJ2219 -E-XL-TVP2 cylindrical roller bearing, measuring 95 × 170 × 43 mm, serves as a separable support bearing designed to withstand high radial loads.

The NJ2219 -E-XL-TVP2 cylindrical roller bearing is a single-row roller bearing from FAG with a cylindrical bore. Thanks to the line contact between the rollers and raceways, the design can withstand high radial forces. With an internal diameter of 95 mm, an external diameter of 170 mm and a width of 43 mm, this design is conceived as an open bearing without an integrated seal. The bearing housing can be lubricated with either grease or oil via the surrounding structure.

What loads does the NJ2219 -E-XL-TVP2 cylindrical roller bearing support during operation?

The NJ design functions as a support bearing for shaft mountings subject to high radial forces and single-sided axial loads. The bearing supports axial forces in one direction and allows a defined axial displacement in the opposite direction. In this way, the bearing arrangement compensates for thermal length changes in the supported shaft during operation without generating additional axial stresses in the system.

What is the function of the polyamide cage and the separable design?

The TVP2 version features a polyamide cage, which contributes to low inertia and smooth rolling action. Together with tolerance class P0/PN (ABEC 1) and standard radial clearance, the bearing is designed for a temperature range of -30 to +120 degrees. As the inner ring can be removed from one side, the inner and outer rings can be fitted separately onto the shaft and housing. The outer ring is manufactured without a groove or lubrication bore.
