Cylindrical Roller Bearings FAG NU308 -E-XL-TVP2

The FAG NU308 -E-XL-TVP2 cylindrical roller bearing, measuring 40x90x23 mm, serves as a single-row non-locating bearing for high radial loads.

The FAG NU308 -E-XL-TVP2 cylindrical roller bearing, as a single-row radial roller bearing, accommodates high radial loads. Thanks to the line contact of the cylindrical rollers, the design can withstand high radial forces. The NU design is characterised by two fixed flanges on the outer ring, whilst the inner ring remains flangeless. The component has a bore of 40 mm, an outer diameter of 90 mm and a width of 23 mm.

What function does the NU308 -E-XL-TVP2 cylindrical roller bearing fulfil as a non-locating bearing?

This roller bearing is primarily used where purely radial forces are present and axial shaft expansion needs to be compensated for. As the inner ring has no flanges, it can be removed from either side and moved axially relative to the outer ring. This feature allows the bearing to compensate for changes in shaft length caused by thermal expansion without inducing stress. The separate installation of the inner ring and outer ring simplifies assembly in cases of tight fits on the shaft and housing.

What are the key features of the cage and design?

The TVP2 polyamide cage guides the rollers quietly and is characterised by its low weight. The bearing is designed for a temperature range of -30 to +120 degrees. This is an open design without an integrated seal and without a lubrication bore in the outer ring. A suitable external housing seal and a lubricant supply are required for operation. The bearing is manufactured to tolerance class P0/PN or ABEC 1.
