Cylindrical Roller Bearings FAG NUP318 -E-XL-TVP2

The FAG NUP318 -E-XL-TVP2 cylindrical roller bearing is a single-row fixed bearing with a 90 mm bore, offering high radial load capacity and axial guidance on both sides.

The NUP318 -E-XL-TVP2 cylindrical roller bearing is a single-row radial roller bearing from FAG Rolling Bearings with main dimensions of 90 × 190 × 43 mm. Thanks to the line contact between the rollers and raceways, the design can withstand high radial forces. As an open bearing, this version requires lubrication via the surrounding housing. It is manufactured to the standard tolerance class P0/PN or ABEC 1.

In which applications is the NUP318 -E-XL-TVP2 fixed bearing used?

This rolling bearing is used wherever high radial loads are present and the shaft needs to be fixed in both axial directions at the same time. Typical applications include shaft mountings with guidance on both sides. As the outer ring has no groove or lubrication bore, the lubricant is supplied from the end faces. The open bearing design allows for flexible selection of grease or lubricating oil to suit the specific operating environment.

What functions do the NUP design and the polyamide cage fulfil in the NUP318 -E-XL-TVP2?

The NUP design classifies this model as a fixed bearing: two fixed flanges on the outer ring, together with one fixed flange and one loose flange disc on the inner ring, enable the bearing to accommodate axial forces from varying directions. The integrated polyamide cage (TVP2) guides the roller elements with low friction and is characterised by its low weight. The permissible temperature range is from –30 to +120 degrees Celsius. This version has a standard radial clearance for normal installation conditions without extreme temperature differences.
