For equipment that must handle significant radial loads at considerable speeds, SKF cylindrical roller bearings are a common choice. The NNU 4164 F/C3W33 is a double row design built with cylindrical rollers and a machined steel cage. MR Industrial Accessories LLC supplies this bearing to customers across the United States and Latin America. If you are replacing a worn unit or selecting a bearing for a new application, our team can help you confirm the right option.

Reading the designation helps you verify what you are ordering. NNU identifies a double row cylindrical roller bearing with two inner rings and a flangeless outer ring. The number 4164 covers the size and dimensional series. The F suffix points to a high-strength machined steel cage. C3 means radial internal clearance is greater than standard, and W33 indicates a groove and three lubrication holes in the outer ring. This breakdown lets you quickly confirm the constructional features.

These bearings are found in gearboxes, rolling mills, pulp and paper machines, high-flow pumps, industrial fans, and mining equipment, as well as machine tool spindles and heavy transport rollers. They suit applications where radial loads are heavy and speeds range from moderate to high, including environments with vibration and variable temperatures.

When selecting a cylindrical roller bearing, consider the radial load, rotation speed, and operating conditions. C3 clearance is often specified where thermal gradients exist between inner and outer rings, or where the fit is interference. Lubrication by grease or oil should match speed and working temperature; the W33 groove and holes simplify relubrication. Proper alignment between housing and shaft is essential, and mounting should be done with the correct tools to avoid damaging rollers or raceways.

Double row cylindrical roller bearings are made to international standards, so dimensional interchangeability between brands is possible. For a replacement, always compare main dimensions, cage type, and internal clearance. A bearing with C3 is not interchangeable with one without a suffix, and W33 may be critical if the original design requires lubrication through the outer ring.
