FAG NNC V series cylindrical roller bearings are double row units with a steel cage and high radial load capacity for their section. They suit applications where the shaft must be guided precisely and carry significant radial loads, such as gearboxes, machine tools and transmission equipment. MR Industrial Accessories LLC supplies these bearings to customers across the United States and in several Latin American countries, and can help you confirm the right part number.

The part number is built in blocks. The letters NNC denote a double row cylindrical roller bearing with both rows guided; the V suffix means a steel cage, and in some cases there is no separate inner ring. The digits that follow, as in NNC4830V or NNC4844V, indicate series size and bore diameter. The same pattern appears in NNC4832V and NNC4838V: type letters, size number and execution suffix. Always check the manufacturer's data sheet to interpret a specific code.

These bearings are found where radial load is high and axial space is limited: gear reducers and gearboxes, machine tool spindles, industrial pumps, process fans and rolling mills. They are common in maintenance work at steel plants, cement plants, paper mills and food processing facilities whenever the design calls for a double row with good rigidity. MR Industrial Accessories LLC supports workshops and plants in selecting and replacing these components.

To choose the correct part number, start with shaft diameter, load type and operating speed. During mounting, check alignment between shaft and housing, interference fit and internal clearance; poor alignment shortens bearing life. Use the lubricant specified for the operating temperature and speed, and make sure sealing protects against dust and moisture for the environment. If the equipment runs with vibration, also inspect the housing condition.

Double row cylindrical roller bearings are often interchanged between manufacturers by series number and dimensions, but relying on the code alone is risky: cage, clearance and tolerance differences change behavior. Brands such as SKF, NSK, NTN or Timken offer equivalent lines, though suffixes may vary. Compare the complete designation and mounting dimensions before replacing. If in doubt, send us the old code and shaft dimensions.
