Cylindrical Roller Bearings FAG NJ2318 -E-XL-TVP2

The NJ2318 -E-XL-TVP2 cylindrical roller bearing, measuring 90 × 190 × 64 mm, accommodates high radial forces as well as unilateral axial loads during operation.

The FAG NJ2318 -E-XL-TVP2 cylindrical roller bearing is a single-row rolling bearing for industrial applications. As an open radial roller bearing without a seal, this version is designed for use in externally lubricated environments. The polyamide cage guides the cylindrical rollers and ensures smooth running. With a bore of 90 mm, an outside diameter of 190 mm and a width of 64 mm, this roller bearing withstands high radial forces.

What loads does the NJ2318 -E-XL-TVP2 cylindrical roller bearing accommodate as a support bearing?

As a support bearing, this design accommodates not only high radial forces but also axial forces from one direction, whilst the inner ring remains removable from one side. The defined displacement within the bearing compensates for axial shaft expansion in the opposite direction. This design also facilitates the separate mounting of the inner and outer rings onto the shaft and housing.

What properties do the polyamide cage and standard bearing clearance offer in the NJ2318 -E-XL-TVP2?

The polyamide cage with the TVP2 suffix reduces the weight of the rotating components compared with metal versions and ensures smooth running. The cage material retains its dimensional stability at operating temperatures ranging from –30 to +120 degrees. Together with the standard radial bearing clearance and tolerance class P0 or ABEC 1, the bearing is designed for standard operating conditions. As the outer ring has no groove or lubrication bore, the lubricant is supplied from the side via the housing.
