Cylindrical Roller Bearings FAG NJ2216 -E-XL-TVP2

The FAG NJ2216 -E-XL-TVP2 cylindrical roller bearing (80x140x33 mm) accommodates high radial loads as well as unilateral axial forces when used as a support bearing.

The NJ2216 -E-XL-TVP2 cylindrical roller bearing provides designs with a single-row radial roller bearing from FAG. This open-type bearing has the following main dimensions: 80 mm bore, 140 mm outside diameter and 33 mm width. Due to the line contact between the rolling elements, the bearing is suitable for bearing arrangements and shaft guides that have to withstand heavy transverse forces. As the inner ring is designed to be removable from one side, the inner and outer rings can be fitted separately.

When is the NJ2216 -E-XL-TVP2 cylindrical roller bearing suitable as a support bearing?

Designs featuring the NJ series are used when a shaft needs to be guided axially in one direction. The outer ring has two fixed flanges, whilst the inner ring has one fixed flange. As a result, the assembly supports axial forces from one direction but allows axial displacement in the opposite direction. In combination with a suitable mating bearing, this arrangement compensates for temperature-induced changes in the shaft’s length.

What are the key operating characteristics of the TVP2 polyamide cage?

The suffix TVP2 denotes a solid polyamide cage which guides the cylindrical rollers within the bearing. This material helps to dampen noise and reduces the weight of the rotating unit. The bearing is designed for a temperature range of -30 to +120 degrees. When designing the bearing mounting, care must be taken to ensure an external lubricant supply, as the outer ring is designed without a groove or lubrication bore.
