Cylindrical Roller Bearings FAG NU2203 -E-XL-TVP2

The FAG NU2203 -E-XL-TVP2 cylindrical roller bearing, measuring 17x40x16 mm, offers a high radial load capacity as a separable single-row bearing.

The NU2203 -E-XL-TVP2 cylindrical roller bearing is a single-row radial roller bearing for applications involving significant radial forces. The cylindrical rolling elements make line contact with the raceways, enabling the roller bearing to withstand higher radial loads than a ball bearing of the same dimensions. With a bore of 17 mm, an outer diameter of 40 mm and a width of 16 mm, this design complies with standardised mounting spaces.

In which bearing arrangements is the NU2203 -E-XL-TVP2 fitted?

This rolling bearing is used in designs where primarily pure radial forces are to be supported and axial length changes of the shaft need to be compensated for. As a non-locating bearing, the NU design does not absorb any axial forces. As the inner ring has no guide flanges, the shaft shifts relative to the housing during thermal expansion without generating axial stresses in the bearing seat.

What are the functions of the NU design and the polyamide cage?

The NU design features two fixed flanges on the outer ring, whilst the inner ring is flangeless and can be removed from both sides. This separability simplifies installation, as the inner and outer rings can be mounted separately on the shaft and housing. The polyamide cage (TVP2) guides the cylindrical rollers quietly and reduces the weight of the moving guide elements in the rolling element set.
