Cylindrical Roller Bearings FAG NU204 -E-XL-TVP2-C3
The FAG NU204 -E-XL-TVP2-C3 cylindrical roller bearing is an open, single-row idler bearing measuring 20 × 47 × 14 mm, designed for high radial loads.
The NU204 -E-XL-TVP2-C3 cylindrical roller bearing is an open roller bearing with a 20 mm bore, an outer diameter of 47 mm and a width of 14 mm. As a radial roller bearing, this FAG component can withstand very high radial loads. As the outer ring has solid flanges and the inner ring is flangeless, the inner ring can be removed from either side. This simplifies installation and subsequent maintenance work.
What is the NU204 -E-XL-TVP2-C3 cylindrical roller bearing suitable for?
In mechanical designs, this bearing acts as a floating bearing to axially compensate for thermally induced changes in shaft length. Cylindrical rollers make line contact with the raceways and transmit high radial forces. Typical applications include bearing arrangements where radial guidance is required whilst allowing for axial movement. The permissible temperature range is from –30 to +120 degrees Celsius.
What is the function of the polyamide cage and the C3 clearance?
The version with the suffix TVP2 features a polyamide cage, which ensures smooth running. In addition, this variant has an increased bearing clearance of group C3. This slightly increased radial bearing clearance helps to ensure that the bearing does not become stressed, even with tight fits or due to operational heating. The outer ring has no groove or lubrication bore, so lubrication is supplied via the housing or external sealing systems.
What characterises the NU design in the NU204 -E-XL-TVP2-C3 cylindrical roller bearing?
The NU design is characterised by two fixed shoulders on the outer ring and a shoulderless inner ring. This allows the inner ring to be moved axially in both directions and removed completely. In shaft bearings, this design is specifically used as a floating bearing to compensate for axial thermal expansion without causing stress.
What are the dimensions of the NU204 -E-XL-TVP2-C3 cylindrical roller bearing?
This cylindrical roller bearing has an inner diameter of 20 mm, an outer diameter of 47 mm and a width of 14 mm. It is manufactured to tolerance class P0/PN or ABEC 1 and therefore complies with the standard tolerances for industrial applications.
What does the designation ‘C3’ mean for this cylindrical roller bearing?
The suffix C3 indicates a bearing clearance that is greater than the standard bearing clearance. It compensates for a radial clearance deficit caused by tight shaft and housing fits or temperature differences between the inner and outer rings during operation. This ensures that the rotational movement is maintained without any impermissible preload.
What are the features of the TVP2 polyamide cage?
The TVP2 cage is made of polyamide and maintains a precise distance between the rollers. Plastic cages have a low mass, operate with low vibration and reduce inertial forces during changes in rotational speed. The material limits the operating temperature range of the bearing assembly to between –30 and +120 degrees Celsius.
How is the NU204 open cylindrical roller bearing lubricated and sealed?
As the bearing is an open design and does not have integrated sealing washers, it requires lubrication from the surrounding structure. Depending on the application, you can use either grease or oil. Protection against dirt and lubricant loss is provided by external sealing elements in the housing.
Can the bearing accommodate axial forces?
No, a NU-type cylindrical roller bearing is designed to support purely radial forces. As the inner ring has no flanges, the bearing provides no guidance in the axial direction. For combined loads consisting of radial and axial forces, the shaft must be fitted with an additional fixed bearing.
