Cylindrical Roller Bearings FAG NJ2220 -E-XL-TVP2-C3

The FAG NJ2220 -E-XL-TVP2-C3 cylindrical roller bearing, measuring 100x180x46 mm, offers high radial load-carrying capacity and axial guidance in one direction.

The NJ2220 -E-XL-TVP2-C3 cylindrical roller bearing is a single-row radial roller bearing for industrial applications. With a bore of 100 mm, an outside diameter of 180 mm and a width of 46 mm, the design accommodates heavy radial loads. As a support bearing, it guides the shaft axially in one direction, whilst the inner ring remains removable from one side. FAG manufactures this version with a lightweight polyamide cage and in tolerance class P0/PN or ABEC 1.

In which installation situations is the NJ2220 -E-XL-TVP2-C3 design required?

This design is used in bearing arrangements that require one-sided axial guidance in addition to high radial forces. Thanks to the line contact of the cylindrical rollers, the bearing can accommodate high transverse forces. The NJ design acts as a support bearing in this context: it supports axial forces acting from one side. In the opposite direction, the bearing assembly allows for axial displacement, thereby compensating for thermal length changes in the shaft without causing mechanical stress.

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

The polyamide cage (TVP2) is characterised by its low mass, elasticity and smooth running. In combination with the slightly increased radial bearing clearance C3, the bearing is suitable for operating conditions involving heat build-up or tight fits. This prevents the rollers from seizing up due to thermal expansion. The open bearing without a seal is designed for a temperature range of -30 to +120 degrees and can be flexibly integrated into existing lubrication systems.
