Cylindrical Roller Bearings FAG NU2209 -E-XL-JP1-C3

The FAG NU2209 -E-XL-JP1-C3 cylindrical roller bearing, with main dimensions of 45 × 85 × 23 mm, accommodates high radial forces as a non-locating bearing.

The NU2209 -E-XL-JP1-C3 cylindrical roller bearing is a single-row radial roller bearing from FAG designed for high radial loads. Thanks to its cylindrical rollers, this bearing provides line contact with the raceway, ensuring high rigidity during operation. As an open design without an integrated seal, the component is designed for external lubrication systems. The integrated sheet steel cage guides the rolling elements with minimal vibration. The standardised tolerance class P0 or ABEC 1 enables precise use in demanding shaft bearings in mechanical engineering.

In which installation situations does the NU2209 -E-XL-JP1-C3 cylindrical roller bearing prove its worth?

This radial bearing is primarily used where high radial forces are present and axial displacement of the shaft must be compensated for. As a non-locating bearing, the NU design features two fixed flanges on the outer ring, whilst the inner ring is flangeless. This allows the inner ring to move freely axially relative to the outer ring without causing internal stresses. Typical applications include bearing arrangements where the shaft undergoes thermal linear expansion. The design is suitable for operating temperatures ranging from –30 to +150 degrees Celsius.

What do the NU design and the C3 clearance mean when selecting bearings?

In the NU design, the inner ring can be removed from both sides, which simplifies the assembly of the shaft and housing. Both bearing rings can be fitted separately. The suffix C3 indicates a slightly increased radial bearing clearance compared to the standard range. This is advantageous when tight fits or temperature differences between the inner and outer rings reduce the operating clearance during operation. Before installation, the main dimensions – a 45 mm bore, an 85 mm outer diameter and a 23 mm width – must be taken into account for the respective bearing seat.
