FAG NNC V series cylindrical roller bearings are double row bearings with a steel cage and high radial load capacity for their section. They are used in applications where the shaft must be guided precisely and withstand significant radial loads, such as gearboxes, machine tools and transmission equipment. MR Accesorios Industriales supplies them in Buenos Aires, Argentina, and advises you on choosing the correct part number.

The designation of this family is read in blocks: the letters NNC identify a double row cylindrical roller bearing with both rows guided and the suffix V indicates that it comes with a steel cage, without a separate inner ring in some cases. The numbers that follow, as in NNC4830V or NNC4844V, correspond to the series size and bore diameter. In the examples NNC4832V and NNC4838V the same structure is seen: type letters, size number and execution suffix. To interpret each code, consult the manufacturer's data sheet.

This type of bearing appears in equipment where radial load is high and axial space is limited: gear reducers and gearboxes, machine tool spindles, industrial pumps, process fans and rolling mills. In the Argentine market they are found in maintenance of steel plants, cement plants, paper mills and in the food industry, whenever the design calls for a double row with good rigidity. MR Accesorios Industriales supports workshops and plants in Buenos Aires and the interior in the replacement of these components.

To select the correct part number, start with the shaft diameter, the type of load and the operating revolutions. During mounting, verify the alignment between shaft and housing, the interference fit and the internal clearance; poor alignment shortens bearing life. Lubrication must be the one indicated by the manufacturer for the operating temperature and speed, and sealing must protect against dust and moisture according to the environment. If the equipment operates with vibration, also check the condition of the housing.

Regarding equivalents, double row cylindrical roller bearings are interchanged between manufacturers by series number and dimensions, but it is not advisable to rely only on the code: there are differences in cage, clearance and tolerances that change behavior. Brands such as SKF, NSK, NTN or Timken offer equivalent lines, although the suffix may vary. The correct approach is to compare the complete designation and mounting dimensions before replacing. If in doubt, send us the old code and shaft dimensions.

If you need a bearing from this series, write to us via WhatsApp with the code or model shown on the equipment plate.
