Cylindrical Roller Bearings FAG NU305 -E-XL-TVP2-C3

The FAG NU305 -E-XL-TVP2-C3 cylindrical roller bearing, with dimensions of 25 × 62 × 17 mm, provides a robust floating support with increased radial clearance.

This single-row cylindrical roller bearing, NU305 -E-XL-TVP2-C3, is primarily designed to accommodate high radial forces. Thanks to the line contact between the rollers and the raceways, the design can withstand higher radial loads than a deep-groove ball bearing of the same size. As the inner ring has no flanges, it can be withdrawn from either end. This allows the bearing to compensate for axial changes in shaft length directly within the bearing without inducing stress.

When is the NU305 design suitable as a non-locating bearing?

In many machine designs, the rotating shaft expands during operation due to heat generation. The NU305 -E-XL-TVP2-C3 cylindrical roller bearing acts purely as a floating bearing in this context. Whilst a fixed bearing elsewhere fixes the shaft axially, the flangeless design of the NU inner ring allows for free axial movement. Typical applications include industrial drives and rolling bearing arrangements subject to high radial loads.

What do the TVP2 polyamide cage and the C3 clearance mean?

The suffix TVP2 denotes a polyamide cage, which guides the cylindrical rollers precisely and contributes to low noise levels. The permissible temperature range is from –30 to +120 degrees Celsius. The C3 clearance class denotes increased radial clearance when new. This prevents the rolling elements from seizing up when tight fits cause the rings to expand or when temperature differences occur between the inner and outer rings.
