Cylindrical Roller Bearings FAG NJ2317 -E-XL-TVP2-C3

The FAG NJ2317 -E-XL-TVP2-C3 cylindrical roller bearing, measuring 85x180x60 mm, offers high radial load-carrying capacity and acts as a support bearing with an axial guidance function.

The FAG NJ2317 -E-XL-TVP2-C3 cylindrical roller bearing is a single-row radial roller bearing designed for demanding operating conditions. Thanks to the line contact between the cylindrical rollers and the raceways, the design can withstand high radial loads. This open bearing has the following main dimensions: 85 mm bore diameter, 180 mm outer diameter and 60 mm width. A lightweight polyamide cage guides the cylindrical rolling elements and ensures low-vibration operation within the permissible temperature range of –30 to +120 degrees Celsius.

What is the NJ2317 -E-XL-TVP2-C3 cylindrical roller bearing suitable for?

This bearing design is used when, in addition to high radial forces, unidirectional axial forces act on the shaft. As a support bearing, the outer ring has two fixed flanges, whilst the inner ring has one fixed flange and is removable from one side. This allows the bearing to be supported in one axial direction, whilst axial displacement is still possible in the opposite direction. This also facilitates the separate assembly of the inner and outer rings.

What are the advantages of a polyamide cage and C3 clearance?

The polyamide cage (TVP2) is characterised by its low mass, which reduces inertial forces as well as minimising friction and noise. The increased radial clearance (C3) compensates for operational temperature differences between the inner and outer rings, as well as tight fits, ensuring that the bearing rotates freely without constraint. As the outer ring is designed without a lubrication groove or bore and the bearing runs in an open configuration, the supply of grease or lubricating oil is provided via the housing design.
