Cylindrical Roller Bearings FAG NUP308 -E-XL-TVP2-C3

The FAG NUP308 -E-XL-TVP2-C3 cylindrical roller bearing, measuring 40 × 90 × 23 mm, serves as a heavy-duty fixed bearing for combined radial and axial loads.

The NUP308 -E-XL-TVP2-C3 cylindrical roller bearing is a single-row rolling bearing with cylindrical rollers, designed primarily to accommodate high radial forces. Thanks to the line contact between the rollers and raceways, the bearing distributes mechanical loads evenly. This model is manufactured by FAG and has a bore of 40 mm, an outer diameter of 90 mm and a width of 23 mm. It is operated as an open bearing without an integrated seal.

In which applications is the NUP design used as a fixed bearing?

In bearing arrangements with high radial forces and a shaft supported at both ends, this design provides axial restraint. The NUP design features a fixed bearing with two fixed flanges on the outer ring and one fixed flange and one loose flange disc on the inner ring. As a result, the rolling bearing absorbs axial forces in both directions and limits the axial play of the mounted shaft within the housing.

What are the key features of the polyamide cage and the C3 clearance?

The lightweight polyamide window cage dampens running noise and reduces centrifugal forces that occur under dynamic loading. The slightly increased radial clearance (C3) compensates for thermally induced dimensional changes within a temperature range of -30 to +120 degrees. It also allows for tight fits without unduly restricting the radial operating clearance. The rolling bearing is manufactured to tolerance classes P0/PN or ABEC 1.
