Cylindrical Roller Bearings FAG NUP314 -E-XL-TVP2

The FAG NUP314 -E-XL-TVP2 cylindrical roller bearing, with dimensions of 70x150x35 mm, offers high radial load-carrying capacity as a compact fixed bearing.

The FAG NUP314 -E-XL-TVP2 cylindrical roller bearing is a single-row rolling bearing with a cylindrical bore designed for heavy radial loads. With dimensions of a 70 mm bore, 150 mm outside diameter and 35 mm width, the bearing features cylindrical rollers with line contact. The fixed-end bearing design accommodates not only primary radial forces but also axial guidance forces in both directions. For design and workshop use, the tolerance class P0/PN (ABEC 1) combines standardised interchangeability with defined running accuracy.

In which bearing arrangements is the NUP314 -E-XL-TVP2 cylindrical roller bearing used?

This bearing is used in shaft support arrangements where rigid guidance and high radial loads are required. Typical applications include bearing arrangements with high radial forces where precise axial positioning of the shaft is also required. As a fixed bearing, the NUP design secures the shaft axially relative to the housing in both directions. Designers utilise this property to specifically absorb axial displacements at a defined bearing location, whilst adjacent floating bearings compensate for thermal length changes in the shaft.

What are the distinctive features of the NUP design with a polyamide cage?

The polyamide window cage (suffix TVP2) is characterised by its elastic guidance of the rolling elements and low weight. This material is designed for temperatures ranging from –30 to +120 degrees. The NUP design combines two fixed flanges on the outer ring with one fixed flange and one loose flange disc on the inner ring to provide axial guidance on both sides. As the bearing is of open design and the outer ring has no groove or lubrication bore, the lubricant is supplied via the surrounding housing structure.
