Cylindrical Roller Bearings FAG NJ2304 -E-XL-TVP2

The NJ2304 -E-XL-TVP2 cylindrical roller bearing from FAG Wälzlager, with dimensions of 20x52x21 mm, withstands high radial loads and provides single-sided axial support for shafts.

The NJ2304 -E-XL-TVP2 cylindrical roller bearing is a single-row radial roller bearing in a support bearing design. The open bearing has an outer ring with two fixed flanges and an inner ring with one flange, enabling it to support axial forces from one direction. Thanks to the line contact between the rolling elements and the raceways, the design can withstand high radial loads whilst maintaining high structural rigidity. A polyamide cage guides the rollers, ensuring quiet and low-friction operation.

In which applications is the NJ2304 -E-XL-TVP2 cylindrical roller bearing used?

This radial roller bearing is primarily used in designs where high radial forces act on the shaft. Thanks to the NJ design, the bearing compensates for changes in the shaft’s length in one direction, whilst the opposite side is axially guided. Designs utilise this feature in combination with a non-locating bearing to accommodate thermal length changes in the shaft. Furthermore, the inner ring, which can be removed from one side, allows for the separate installation of both rings.

What are the distinctive features of the NJ design with a polyamide cage?

The TVP2 version features a polyamide cage designed for a temperature range of -30 to +120 degrees. The material absorbs shocks and reduces running noise compared with versions featuring a sheet steel cage. As this is an open bearing without an integrated seal, lubrication must be supplied via the housing and a seal against dirt and moisture must be provided by the customer. The bearing complies with the standard tolerance class P0/PN or ABEC 1.
