Cylindrical Roller Bearings FAG NU2304 -E-XL-TVP2

The single-row FAG cylindrical roller bearing NU2304 -E-XL-TVP2 with a 20 mm bore accommodates high radial loads and compensates for axial length changes as a non-locating bearing.

This open NU2304 -E-XL-TVP2 cylindrical roller bearing from FAG is designed for purely radial loads in mechanical and plant engineering. With key dimensions of a 20 mm bore diameter, a 52 mm outer diameter and a width of 21 mm, this design complies with standard tolerance class P0 (PN or ABEC 1). A polyamide cage guides the cylindrical rollers evenly within the rolling element ring. The open design, without a groove or lubrication bore in the outer ring, requires external sealing and allows for direct lubricant supply via the surrounding structure.

What is the NU2304 -E-XL-TVP2 cylindrical roller bearing suitable for?

The NU2304 -E-XL-TVP2 cylindrical roller bearing is suitable for bearing arrangements subject to significant radial loads, where thermally induced changes in shaft length must be compensated for without restriction. In radially loaded shaft bearings, this component acts as a pure non-guiding bearing, supporting the load without providing axial guidance. Due to the line contact of the cylindrical rolling elements, the bearing can withstand high transverse forces. The permissible temperature range is from –30 °C to +120 °C.

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

In the NU design, the outer ring has two fixed flanges, whilst the inner ring is flangeless and can be removed from both sides. This facilitates both installation and removal from the housing, as both rings can be mounted independently of one another onto the shaft and the housing. The integrated polyamide cage (TVP2) ensures quiet roller operation and reduces the weight of the component. As the single-row roller bearing is manufactured with standard radial clearance, it is suitable for standard installation conditions.
