Cylindrical Roller Bearings FAG NUP211 -E-XL-TVP2-C3

The FAG NUP211 -E-XL-TVP2-C3 cylindrical roller bearing is used as a fixed bearing for shafts with a 55 mm bore under high radial loads.

The NUP211 -E-XL-TVP2-C3 cylindrical roller bearing is a single-row radial roller bearing with standard tolerance P0/ABEC 1 and main dimensions of 55 x 100 x 21 mm. The manufacturer, FAG, produces this design with two fixed flanges on the outer ring and one fixed flange and one loose flange disc on the inner ring. This enables the unit to absorb radial loads whilst simultaneously fixing the shaft in both axial directions. The open bearing, without sealing discs, allows for flexible lubrication within the housing.

What is the NUP211 -E-XL-TVP2-C3 cylindrical roller bearing suitable for?

Design engineers primarily use this design as a fixed bearing location when, in addition to high radial loads, axial forces act on both sides of the shaft. Due to the line contact of the cylindrical rollers, the component can withstand high transverse forces. Typical applications are found in industrial bearing arrangements subject to combined radial and axial loads. The open outer ring without a ring groove requires external sealing of the housing assembly, but facilitates the unimpeded exchange of lubricant within the system.

What is the function of the polyamide cage and the C3 bearing clearance in this design?

The designation TVP2 denotes a solid polyamide cage which guides the roller elements quietly and, thanks to its low weight, promotes favourable running characteristics. The permissible temperature range extends from –30 to +120 degrees Celsius. The increased bearing clearance class C3 compensates for operational heating or tighter fits between the shaft and housing, ensuring that the rolling elements do not jam even under thermal load. The component does not have integrated electrical insulation.
