Cylindrical Roller Bearings FAG NU215 -E-XL-TVP2-C3

FAG single-row cylindrical roller bearing NU215 -E-XL-TVP2-C3, dimensions 75x130x25 mm, floating design and increased C3 clearance for high radial loads.

The NU215 -E-XL-TVP2-C3 cylindrical roller bearing from FAG is an open, single-row radial roller bearing designed for demanding industrial applications. With a bore of 75 mm, an outside diameter of 130 mm and a width of 25 mm, this design can withstand high radial forces. Thanks to the line contact between the cylindrical rollers and raceways, the design offers high radial rigidity. The bearing features a lightweight polyamide cage and operates within a temperature range of -30 to +120 degrees.

What is the NU215 -E-XL-TVP2-C3 cylindrical roller bearing suitable for?

This rolling bearing is primarily used where purely radial forces are acting and axial length changes in the shaft need to be compensated for. As a floating bearing of the NU design, this model has two fixed flanges on the outer ring, whilst the inner ring is flangeless and removable from both sides. As a result, the bearing assembly compensates for thermal linear expansion of the shaft directly within the bearing. Typical applications include shaft mountings subject to high radial loads and assemblies that can be fitted separately.

What does the C3 bearing clearance mean for this FAG cylindrical roller bearing?

The designation C3 indicates a slightly increased radial clearance compared with the standard CN version. This additional clearance is recommended where tight fits on the shaft or in the housing result in a significant radial fit allowance. Furthermore, the increased operating clearance helps to prevent the rolling elements from becoming stressed due to operational temperature differences between the inner and outer rings. During design, it is important to ensure that the open bearing is sealed against the ingress of dirt and supplied with sufficient lubricant.
