Cylindrical Roller Bearings FAG NU2207 -E-XL-TVP2-C3

FAG NU2207 -E-XL-TVP2-C3 cylindrical roller bearing: Single-row idler bearing with polyamide cage and increased clearance (C3), dimensions 35x72x23 mm.

The NU2207 -E-XL-TVP2-C3 cylindrical roller bearing from FAG is a radial rolling bearing designed to withstand high radial loads. Thanks to the line contact between the rollers and raceways, the design can handle transverse forces in compact installations. The single-row bearing has a bore of 35 mm, an outer diameter of 72 mm and a width of 23 mm. As it is designed as an open bearing, lubricant can reach the rolling elements unhindered.

What is the NU2207 -E-XL-TVP2-C3 cylindrical roller bearing suitable for?

This support bearing guides shafts purely radially and allows for axial length changes within the bearing. The inner ring has no flanges and can be withdrawn from either side, thereby compensating for thermal shaft expansion without causing axial stress. Typical applications are found in mechanical engineering for shaft mountings subject to purely radial loads. The integrated polyamide cage guides the rolling elements with low vibration and is suitable for operating temperatures ranging from –30 to +120 degrees Celsius.

When is the NU design with C3 clearance the right choice?

The version with C3 bearing clearance offers advantages when temperature differences occur between the inner and outer rings during operation, or when tight fits on the shaft reduce the radial clearance. The increased bearing clearance helps ensure that the rolling elements roll freely even when heated during operation. As the outer ring is manufactured without a groove or lubrication bore, the lubricant is supplied directly from the end face. Any external sealing of the bearing housing must be adapted to the ambient conditions.
