Cylindrical Roller Bearings FAG NU310 -E-XL-TVP2-C3

The FAG NU310 -E-XL-TVP2-C3 cylindrical roller bearing, with dimensions of 50 × 110 × 27 mm, offers high radial load-carrying capacity and axial length compensation when used as a non-locating bearing.

This single-row cylindrical roller bearing, the NU310 -E-XL-TVP2-C3, is an open roller bearing capable of withstanding very high radial forces. The NU design is characterised by two fixed flanges on the outer ring, whilst the inner ring is flangeless. This allows the inner ring to be removed from both sides, which facilitates the separate assembly of both bearing rings. A lightweight polyamide cage guides the cylindrical rollers in the outer ring. The component is suitable for operating temperatures ranging from –30 to +120 degrees Celsius.

What is the NU310 -E-XL-TVP2-C3 cylindrical roller bearing suitable for in practice?

This design is used in bearing arrangements that must function purely as idler bearings. Thanks to the flangeless design of the inner ring, the bearing compensates for operational length expansion of the shaft internally without generating forces. Typical applications are found in general mechanical engineering for shaft mountings where heavy radial loads are the primary concern. As the outer ring is manufactured without a groove or lubrication bore, the lubricant is supplied via the end faces of the open bearing as a design feature.

What do the C3 bearing clearance and the polyamide cage mean for your operation?

The suffix C3 indicates a slightly increased radial clearance compared with the standard version. This increased clearance between the rollers and raceways counteracts jamming when temperature differences occur between the shaft and housing, or when tight fits cause the inner ring to expand. The polyamide cage reduces friction and promotes smooth running. Thanks to tolerance class P0 (ABEC 1), the bearing meets the usual standards for industrial applications.
