Cylindrical Roller Bearings FAG NJ2306 -E-XL-TVP2-C3

The FAG NJ2306 -E-XL-TVP2-C3 cylindrical roller bearing (30x72x27 mm) accommodates high radial loads as well as unilateral axial forces with a slightly increased C3 bearing clearance.

The NJ2306 -E-XL-TVP2-C3 cylindrical roller bearing is a single-row rolling bearing from FAG with a 30 mm bore, 72 mm outer diameter and 27 mm width. Designed as a support bearing, the NJ version combines two solid flanges on the outer ring with a solid flange on the inner ring. This design accommodates heavy radial loads and guides shafts axially in one direction. Thanks to the integrated TVP2 polyamide cage, the bearing operates quietly. The permissible temperature range is from -30 to +120 degrees.

What is the NJ2306 -E-XL-TVP2-C3 cylindrical roller bearing suitable for?

This single-row cylindrical roller bearing is suitable for bearing arrangements subject to high radial forces, where additional axial guiding forces also act in one direction. Typical applications include general mechanical engineering and industrial powertrains. As the inner ring can be removed from one side, both bearing rings can be fitted independently of one another. As an open bearing design, the bearing housing requires external sealing and a continuous supply of lubricant via the surrounding structure.

What are the functions of the NJ design and the C3 clearance in this bearing?

The NJ design serves as a support bearing and allows axial displacement in one direction, whilst the inner ring flange provides support in the opposite direction. The slightly increased radial clearance (C3) compensates for thermal expansion at operating temperatures up to +120 degrees as well as fit oversizes during operation. The polyamide cage reduces the moving mass of the roller guide. As the outer ring is designed without a groove or lubrication bore, the lubricant must be supplied from the housing side.
