Cylindrical Roller Bearings FAG NU207 -E-XL-TVP2-C3

The FAG NU207 -E-XL-TVP2-C3 cylindrical roller bearing, with a 35 mm bore, functions as a separable idler bearing for high radial loads.

The NU207 -E-XL-TVP2-C3 cylindrical roller bearing is a single-row radial roller bearing from FAG designed for demanding industrial applications. With main dimensions of 35 mm inner diameter and 72 mm outer diameter, as well as a width of 17 mm, the design can withstand high radial forces. Thanks to its open design without an integrated seal, the assembly runs directly in oil- or grease-lubricated systems. The dimensionally stable polyamide cage guides the cylindrical rollers with low friction within the outer ring.

In which installation situations is the NU207 -E-XL-TVP2-C3 cylindrical roller bearing used?

This bearing unit is primarily used as a floating bearing when axial changes in shaft length due to thermal effects need to be compensated for. As the inner ring is flangeless and can be removed from both sides, the shaft can move axially relative to the housing during operation. Typical applications include rigid bearing arrangements subject to high radial loads, in which the inner and outer rings are mounted separately.

What are the distinctive features of the polyamide cage and C3 clearance in the NU207?

The material of the polyamide cage reduces the component’s weight and ensures smooth running during operation. At the same time, its elastic nature absorbs minor impact loads. The version with increased C3 bearing clearance offers more radial clearance when new compared to the standard dimension. This is advantageous when tight fits are required on the shaft and housing, or when significant temperature differences between the inner and outer rings occur during operation. The permissible temperature range is from -30 to +120 degrees.
