Cylindrical Roller Bearings FAG NUP313 -E-XL-TVP2-C3

The FAG NUP313 -E-XL-TVP2-C3 single-row cylindrical roller bearing, measuring 65 × 140 × 33 mm, functions as a fixed bearing designed to accommodate high radial loads and provide axial guidance on both sides.

The NUP313 -E-XL-TVP2-C3 cylindrical roller bearing provides users with an open, single-row rolling bearing for demanding industrial applications. The component features fixed flanges and a loose flange disc, enabling it to guide shafts precisely in both axial directions. Thanks to the line contact between the rollers and raceways, this design can withstand very high radial forces. The bearing is designed for a temperature range of –30 to +120 degrees and complies with the standard tolerance class P0/PN or ABEC 1.

In which applications does the NUP313 -E-XL-TVP2-C3 cylindrical roller bearing prove its worth as a fixed bearing?

This fixed bearing is used in bearing arrangements where high radial forces must be combined with axial guidance. Typical applications are found in mechanical engineering in designs with a defined fixed-floating bearing arrangement. Compared to ball bearings, cylindrical rollers have a larger line contact, which gives the bearing noticeably firm support and a high radial load capacity. As a result, the shaft remains precisely guided in its specified position even under high operating loads.

What features do the TVP2 polyamide cage and the C3 clearance offer?

The suffixes denote specific features designed for demanding operating conditions. The TVP2 polyamide cage ensures low-noise guidance of the rolling elements whilst maintaining a low weight. The C3 designation indicates a slightly increased radial clearance. This additional operating clearance serves to compensate for thermal expansion caused by heating during operation, without the rollers seizing up. As this is an open bearing without an integrated seal and without a lubrication bore in the outer ring, the lubricant is supplied via the housing.
