Cylindrical Roller Bearings FAG NJ2317 -E-XL-TVP2

The FAG NJ2317 -E-XL-TVP2 cylindrical roller bearing (85x180x60 mm) offers high radial load-carrying capacity and, as a support bearing, accommodates unilateral axial forces.

The NJ2317 -E-XL-TVP2 cylindrical roller bearing is a single-row radial roller bearing designed for demanding industrial applications. Thanks to the contact between the cylindrical rollers and the hardened raceways, this design can accommodate high radial loads. With main dimensions of 85 mm bore diameter, 180 mm outer diameter and 60 mm width, this open bearing complies with standardised dimensions. The dimensionally stable polyamide cage guides the rolling elements evenly, ensuring smooth running.

In which installation situations is the NJ2317 -E-XL-TVP2 cylindrical roller bearing used?

This roller bearing is particularly suitable for bearing arrangements where, in addition to predominant radial forces, axial forces also act from one direction. The NJ design features two fixed flanges on the outer ring and one fixed flange on the inner ring. As a result, the bearing acts as a thrust bearing: it absorbs axial loads in one direction whilst allowing axial displacement of the shaft in the opposite direction.

What are the advantages of the support bearing design and the polyamide cage?

The inner ring, which can be removed from one side, facilitates the assembly and disassembly of the bearing assembly, as the inner and outer rings can be fitted separately. The polyamide cage (designation TVP2) is characterised by low friction and elastic damping properties. As this is an open bearing without an integrated seal, the bearing assembly can be integrated into existing lubrication systems. The permissible temperature range is between -30 and +120 degrees.
