Cylindrical Roller Bearings FAG NU319 -E-XL-TVP2

FAG NU319 -E-XL-TVP2 cylindrical roller bearing: Single-row non-locating bearing with a polyamide cage, dimensions 95 × 200 × 45 mm, designed for high radial load capacities.

The FAG NU319 -E-XL-TVP2 cylindrical roller bearing, as a radial rolling bearing, primarily absorbs transverse forces. Thanks to the line contact between the cylindrical rollers and the raceways, the design can withstand high radial loads. With a bore of 95 mm, an outside diameter of 200 mm and a width of 45 mm, this single-row bearing complies with standardised mounting dimensions. As the outer ring is manufactured without a groove or lubrication bore, the lubricant is fed directly into the open bearing.

In which installation situations is the NU319 -E-XL-TVP2 cylindrical roller bearing used?

This single-row roller bearing is primarily designed to accommodate high radial loads whilst allowing for simultaneous changes in shaft length. In combination with a fixed bearing, the NU floating bearing design compensates for thermally induced expansion within the bearing without causing binding. Typical applications include shaft mountings in mechanical engineering where high radial forces are present and axial displacement of the shaft seat is required.

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

The NU design is characterised by two solid flanges on the outer ring, whilst the inner ring is flangeless and can be removed from either side. This separability of the bearing rings facilitates installation and maintenance, as the inner and outer rings can be pressed on separately. The TVP2 polyamide cage guides the rollers quietly whilst being lightweight. With standard radial clearance and tolerance class P0/PN, the bearing is designed for operating temperatures ranging from -30 to +120 degrees.
