Cylindrical Roller Bearings FAG NJ316 -E-XL-TVP2-C3

The FAG NJ316 -E-XL-TVP2-C3 cylindrical roller bearing, with an 80 mm bore and C3 clearance, offers high radial load-carrying capacity for demanding industrial applications.

The FAG NJ316 -E-XL-TVP2-C3 cylindrical roller bearing is a single-row rolling bearing designed for demanding shaft mountings subject to high radial loads. With key dimensions of an 80 mm bore, 170 mm outer diameter and 39 mm width, the design withstands high loads whilst maintaining high rigidity. Thanks to its manufacture to standard tolerance P0 or ABEC 1, the open bearing fits precisely into industrial assemblies. The elastic polyamide cage also ensures smooth running during operation.

In which assemblies does the NJ316 design prove its worth?

As a support bearing with fixed flanges on the outer ring and an inner ring that can be removed from one side, this design guides shafts axially in one direction. In the opposite direction, the design allows for axial displacement, thereby compensating for thermal length changes in the shaft without inducing stress. This design is primarily used in bearing arrangements where, in addition to dominant radial loads, unilateral guiding forces are also present. The open bearing allows for flexible lubrication with oil or grease.

What does the design with a TVP2 cage and C3 bearing clearance mean?

The designation TVP2 refers to a polyamide cage that combines low weight with good damping properties. The increased radial bearing clearance (C3) provides additional clearance between the rollers and raceways. This clearance prevents the bearing from becoming stressed should heating during operation or tight shaft fits reduce the radial clearance. When designing the bearing, the permissible temperature range of -30 to +120 degrees and an external housing seal to protect the raceway must be taken into account.
