Cylindrical Roller Bearings FAG NJ2305 -E-XL-TVP2-C3

The FAG NJ2305 -E-XL-TVP2-C3 cylindrical roller bearing accommodates high radial loads with a 25 mm bore and supports axial forces on one side.

The NJ2305 -E-XL-TVP2-C3 cylindrical roller bearing is a single-row radial roller bearing with line contact between the rollers and raceways. Thanks to this design, the FAG version can withstand high radial forces. The NJ design features two fixed flanges on the outer ring and one fixed flange on the inner ring. As a result, the bearing assembly acts as a support bearing, guiding shafts in one axial direction whilst allowing axial movement in the opposite direction.

What is the NJ2305 -E-XL-TVP2-C3 cylindrical roller bearing suitable for?

Design engineers and maintenance engineers use this roller bearing when shaft supports need to absorb high radial forces. Thanks to its support bearing function, the unit compensates for thermal length changes in the shaft in one direction, whilst supporting forces in the opposite direction. Typical applications include single-sided guidance arrangements. The open bearing can be integrated directly into existing lubrication systems.

What advantages do the polyamide cage and C3 bearing clearance offer in the NJ2305?

The polyamide cage (TVP2) reduces the weight of the rotating rolling element assembly and promotes quiet operation. The increased radial clearance (C3) provides additional radial play. This compensation prevents the rolling elements from seizing up if temperature differences occur between the shaft and housing during operation, or if tight fits cause the inner ring to expand. The permissible temperature range is from -30 to +120 degrees.
