Cylindrical Roller Bearings FAG NJ315 -E-XL-TVP2

The FAG NJ315 -E-XL-TVP2 cylindrical roller bearing, with a 75 mm bore and an outer diameter of 160 mm, provides stable radial support with single-sided axial guidance.

This single-row cylindrical roller bearing, the NJ315 -E-XL-TVP2, primarily absorbs high radial forces and guides the shaft in the axial direction. Designed as an open bearing, it requires external lubrication and a seal on the housing side. FAG equips this version with a lightweight polyamide cage and standard radial clearance. The standardised tolerance class P0/PN allows for direct use in industrial bearing installations with standard dimensional accuracy requirements.

What are the operational applications of the NJ315 -E-XL-TVP2 cylindrical roller bearing?

Typical applications include industrial shaft mountings subject to high radial loads and single-sided guiding forces. Structurally, the NJ design serves as a support bearing: it absorbs radial forces whilst simultaneously limiting the axial displacement of the shaft in one direction. When combined with a suitable mating bearing, this creates an axially guided bearing arrangement. The permissible temperature range extends from –30 to +120 degrees Celsius, making the bearing suitable for the corresponding thermal conditions.

What are the functions of the NJ design and the polyamide cage?

The NJ design features two fixed flanges on the outer ring and one fixed flange on the inner ring. This allows the inner ring to be removed from one side, enabling the inner and outer rings to be fitted separately onto the shaft and into the housing. The integrated polyamide cage guides the cylindrical rolling elements with low noise levels. Thanks to the low mass of the material, inertial forces remain low, which contributes to smooth running even at varying speeds.
