Cylindrical Roller Bearings FAG NU205 -E-XL-TVP2-C3

The single-row cylindrical roller bearing NU205 -E-XL-TVP2-C3 from FAG, with dimensions of 25x52x15 mm, offers high radial load-carrying capacity when used purely as a non-locating bearing.

This NU205 -E-XL-TVP2-C3 cylindrical roller bearing absorbs high radial forces thanks to the line contact of its rollers. This FAG product is designed as an open roller bearing without sealing rings. The inner ring can be withdrawn from both ends, allowing the inner and outer rings to be fitted separately. The tolerances correspond to tolerance class P0/PN or ABEC 1, whilst the outer ring is manufactured without a groove or lubrication bore.

When is the NU design suitable as a non-locating bearing?

The NU design serves as a classic non-locating bearing on rotating shafts. As the inner ring has no flanges, it slides axially within the roller cage in the event of thermal linear expansion. This helps to prevent stress concentrations in the bearing system. Typical applications include situations where strong radial forces act on shafts and a fixed bearing elsewhere provides the guidance. This design cannot transmit purely axial loads.

What are the advantages of a polyamide cage and C3 clearance?

The designation TVP2 stands for a polyamide cage, which ensures smooth running and reduces the bearing weight. Together with the increased radial clearance (C3), this component is well suited to applications where operating temperatures range from -30 °C to +120 °C or where tight fits reduce the radial clearance. The additional bearing clearance compensates for thermal expansion during operation without the bearing seizing up.
