Cylindrical Roller Bearings FAG NJ2319 -E-XL-TVP2-C3

The FAG NJ2319 -E-XL-TVP2-C3 cylindrical roller bearing, with dimensions of 95 × 200 × 67 mm, can withstand very high radial loads and provides single-sided axial support for shafts.

This single-row cylindrical roller bearing, model NJ2319 -E-XL-TVP2-C3, manufactured by FAG, is designed as a support bearing. The outer ring has two solid flanges, whilst the inner ring has one solid flange. Thanks to this design, the roller bearing transmits not only considerable radial loads but also axial forces in one direction. The removable inner ring allows for the separate installation of both bearing rings, saving time and making handling during installation and maintenance easier.

For which loads is the NJ2319 -E-XL-TVP2-C3 cylindrical roller bearing suitable?

The bearing is designed to accommodate high radial loads and to absorb axial forces from one direction. Such bearing arrangements are primarily found on shafts subject to significant radial forces and single-sided thrust loads. As the inner ring is removable from one side, the unit can be fitted flexibly. The open design without integrated seals allows for direct lubrication via the surrounding lubrication system.

What is the function of the support bearing design and C3 clearance?

The NJ design allows for a defined axial displacement in one direction, whilst the opposite side acts as a stop. The increased radial clearance (C3) is significant in the design: it compensates for thermal expansion caused by operating heat and helps to prevent the rollers from seizing. The polyamide cage guides the roller elements with low friction and low noise. The open bearing requires protection against the ingress of dirt via the housing design.
