Cylindrical Roller Bearings FAG NJ317 -E-XL-TVP2-C3

The FAG NJ317 -E-XL-TVP2-C3 cylindrical roller bearing, with dimensions of 85 × 180 × 41 mm, offers high radial load capacity and single-sided axial guidance.

The FAG NJ317 -E-XL-TVP2-C3 cylindrical roller bearing is a single-row rolling bearing designed for demanding industrial applications. Thanks to the line contact between the cylindrical rollers and the raceways, this design can accommodate high radial loads. The design features two fixed flanges on the outer ring and one fixed flange on the inner ring. As a result, the bearing functions as a classic support bearing, which precisely guides a shaft in one axial direction whilst allowing axial displacement in the opposite direction to compensate for thermal length changes.

In which installation situations does the NJ317 -E-XL-TVP2-C3 cylindrical roller bearing prove its worth?

This bearing type is primarily used in bearing arrangements where, in addition to high radial forces, unilateral axial guiding forces are also present. The inner ring can be removed from one side for assembly, which significantly facilitates separate pressing onto the shaft and housing. As this is an open bearing without integrated seals and without a groove or lubrication bore in the outer ring, the lubricant and external housing seal can be precisely tailored to the specific operating environment.

What is the function of the polyamide cage and the C3 clearance in this bearing?

The polyamide cage (TVP2) guides the cylindrical rollers quietly and helps to reduce friction during rotational movements. The slightly increased radial clearance (C3) helps to ensure that sufficient radial operating clearance remains even with tight fits or heat build-up during operation. The specified operating temperature range is from -30 to +120 degrees. Manufactured to tolerance class P0/PN or ABEC 1, the component meets the standard accuracy requirements in general mechanical engineering.
