Cylindrical Roller Bearings FAG NU2311 -E-XL-TVP2

The FAG NU2311 -E-XL-TVP2 cylindrical roller bearing, with dimensions of 55x120x43 mm, offers high radial load-carrying capacity as a separable single-row bearing.

The NU2311 -E-XL-TVP2 cylindrical roller bearing is a single-row rolling bearing for industrial applications subject primarily to radial loads. Thanks to the line contact between the cylindrical rollers and the raceways, the design can accommodate high radial forces. With a bore of 55 mm, an outer diameter of 120 mm and a width of 43 mm, this FAG design is used wherever a rigid and high-load-capacity shaft support is required.

What functions does the NU2311 -E-XL-TVP2 cylindrical roller bearing perform as a non-locating bearing?

In shaft mountings, the bearing serves as a conventional non-locating bearing to support purely radial forces. As the inner ring is flangeless on both sides and removable, the bearing compensates for operational length changes in the shaft axially and without interference directly at the bearing location. This design is used in bearing arrangements that require free axial movement. Furthermore, the separately mountable inner ring facilitates installation in the case of tight fits.

What is the function of the TVP2 polyamide cage?

The designation TVP2 stands for a polyamide cage that guides the cylindrical rollers and maintains a uniform spacing between them. The material dampens vibrations, ensures smooth running and keeps the cage weight low. In combination with the standard radial bearing clearance and tolerance class P0 (ABEC 1), the bearing is designed for a temperature range of -30 to +120 degrees. As this is an open design without sealing washers, operation requires an external housing seal and a lubricant supply.
