Cylindrical Roller Bearings FAG NU224 -E-XL-TVP2

The FAG NU224 -E-XL-TVP2 cylindrical roller bearing, measuring 120 × 215 × 40 mm, offers a heavy-duty solution for radial forces in a compact design.

As a radial rolling bearing, the single-row cylindrical roller bearing NU224 -E-XL-TVP2 can accommodate very high transverse forces. The cylindrical rollers create line contact with the raceway, which is stiffer than point contact. In this FAG design, the inner ring is flangeless and can be removed from both sides. The bearing therefore functions as a floating bearing during operation and compensates for axial length changes of the shaft within the rolling element chamber.

In which installation situations does the NU224 -E-XL-TVP2 design prove its worth?

This roller bearing is primarily used for high radial loads where temperature-induced linear expansion of shafts must be compensated for without constraint. As the outer ring has solid flanges and is designed without a groove or lubrication bore, lubricants are supplied axially via the surrounding structure. This design is suitable for fixed-floating mountings in combination with an axially guiding counter-bearing.

What is the function of the TVP2 polyamide cage in this bearing?

The suffix TVP2 denotes a solid polyamide cage which guides the cylindrical rollers and keeps them spaced apart. This material reduces the weight compared with metal cages and improves start-up behaviour at varying speeds. The permissible temperature range is from –30 to +120 degrees Celsius. Manufacture to tolerance class P0 or ABEC 1 with standard radial clearance allows for direct installation in standardised housing and shaft seats.
