Cylindrical Roller Bearings FAG NJ2315 -E-XL-TVP2

The FAG NJ2315 -E-XL-TVP2 cylindrical roller bearing (75 x 160 x 55 mm) acts as a support bearing and accommodates high radial loads as well as unilateral axial loads.

The FAG NJ2315 -E-XL-TVP2 cylindrical roller bearing is a single-row roller bearing with a 75 mm bore, an outer diameter of 160 mm and a width of 55 mm. Due to the line contact between the rollers and raceways, this design can withstand very high radial forces. In the NJ version, the bearing has two fixed flanges on the outer ring and one fixed flange on the inner ring. It therefore serves as a support bearing for single-sided axial guidance of shafts.

What functions does the NJ2315 -E-XL-TVP2 cylindrical roller bearing fulfil as a support bearing?

This support bearing is used where high radial load capacity needs to be combined with axial guidance in one direction. As the inner ring is removable on one side, the bearing can be displaced axially by a specific amount. This design therefore allows for the compensation of thermal length changes in the shaft in one direction, whilst the fixed inner ring flange absorbs axial forces in the opposite direction. Assembly is flexible due to the separate installation of the inner and outer rings.

What is the function of the TVP2 polyamide cage in this bearing?

The suffix TVP2 denotes a polyamide cage that guides the cylindrical rolling elements and keeps them at a distance from one another. Due to its low weight, the polyamide material reduces the inertial forces that occur during operation. The bearing is designed for a temperature range of -30 to +120 degrees. With standard radial clearance and tolerances to P0/PN or ABEC 1, the component is suitable for standardised installation conditions in industrial bearing arrangements.
