Cylindrical Roller Bearings FAG NJ2314 -E-XL-TVP2

The FAG NJ2314 -E-XL-TVP2 cylindrical roller bearing, measuring 70 × 150 × 51 mm, serves as a radial support bearing with single-sided axial guidance.

As a single-row cylindrical roller bearing, the NJ2314 -E-XL-TVP2 can withstand very high radial loads. With a bore of 70 mm, an outside diameter of 150 mm and a width of 51 mm, this rolling bearing is suitable for demanding industrial applications. The manufacturer, FAG, fits this version with a lightweight polyamide cage. Designed as an open bearing, it can be flexibly integrated into lubricated housing designs and operates within a temperature range of -30 to +120 degrees.

In which installation scenarios does the NJ2314 -E-XL-TVP2 function as a support bearing?

The NJ2314 -E-XL-TVP2 cylindrical roller bearing primarily absorbs loads where high radial forces act within a confined installation space. Due to its NJ design, the bearing functions as a support bearing: It guides the shaft in one axial direction whilst allowing axial displacement in the opposite direction. The inner ring, which can be removed from one side, also facilitates the separate assembly of the shaft and housing. The outer ring has no groove or lubrication bore, ensuring a sealed housing fit.

What is the function of the combination of a polyamide cage and standard bearing clearance?

The polyamide cage, designated TVP2, guides the cylindrical rollers with low friction and dampens vibrations during operation. The low weight of the plastic reduces centrifugal forces during changes in rotational speed. Together with the standard radial bearing clearance and the standard tolerance class P0 (ABEC 1), this variant is ideally suited to precise shaft guidance under balanced thermal conditions. As the open bearing has no integrated seals, you should ensure that the adjacent structure provides suitable sealing and a lubricant supply.
