Cylindrical Roller Bearings FAG NU2215 -E-XL-TVP2-C3

The FAG NU2215 -E-XL-TVP2-C3 single-row cylindrical roller bearing with a 75 mm bore is used as a non-locating bearing for high radial loads.

As a single-row radial roller bearing, the NU2215 -E-XL-TVP2-C3 absorbs high radial forces. With dimensions of a 75 mm bore, 130 mm outer diameter and 31 mm width, this FAG bearing is used in mechanical engineering. As it is an open bearing without an integrated seal, users select grease or lubricating oil suitable for the operating environment. It is manufactured to tolerance class P0 or PN (ABEC 1).

What is the NU2215 -E-XL-TVP2-C3 cylindrical roller bearing suitable for in practice?

As a floating bearing, this design compensates for axial changes in shaft length directly within the bearing. As the inner ring can be removed from both ends, the inner and outer rings can be fitted separately. This helps to prevent internal stresses caused by thermal expansion of the shaft. The bearing is designed for mounting positions where purely radial forces act and impact loads may occur. Thanks to the line contact between the rollers and raceways, the design can accommodate high radial loads.

What are the distinctive features of the design with a TVP2 cage and C3 clearance?

The combination of a polyamide cage and increased C3 bearing clearance offers specific installation advantages. The TVP2 polyamide cage is characterised by its low mass and smooth running. The slightly increased radial clearance (C3) provides additional leeway for applications where tight shaft fits cause the inner ring to expand or where temperature differences arise between the inner and outer rings. The permissible temperature range is between -30 and +120 degrees. The outer ring has no groove and no lubrication bore, which is why the lubricant must be applied from the side.
