Cylindrical Roller Bearings FAG NUP2311 -E-XL-TVP2-C3

The FAG single-row cylindrical roller bearing NUP2311 -E-XL-TVP2-C3, measuring 55x120x43 mm, serves as a fixed bearing for high radial loads.

This open cylindrical roller bearing, the NUP2311 -E-XL-TVP2-C3 from FAG, combines a high radial load capacity with the ability to accommodate axial forces in both directions. The NUP design features two fixed flanges on the outer ring, one fixed flange on the inner ring and a loose flange disc. Thanks to this design, the bearing acts as a fixed bearing and secures the shaft axially within the housing. The component complies with tolerance class P0/PN (ABEC 1) and has no electrical insulation.

What is the NUP2311 -E-XL-TVP2-C3 cylindrical roller bearing suitable for?

Design engineers and maintenance personnel primarily use this bearing arrangement on shafts where heavy radial forces occur and, at the same time, axial fixation on both sides is required. Due to the line contact of the cylindrical rollers, the rolling bearing can withstand high radial loads. Typical applications can be found in industrial machinery and plant where high radial loads occur in combination with precise axial shaft guidance.

What do ‘polyamide cage’ and ‘C3 clearance’ mean in the NUP2311?

The designator TVP2 stands for a polyamide cage, which ensures quiet running and favourable friction coefficients. The suffix C3 indicates a slightly increased radial clearance. This increased radial clearance compensates for thermal expansion at operating temperatures between –30 and +120 degrees, as well as for tight fits. As the bearing is of an open design, users must provide an external lubricant supply and a housing seal.
