The SKF NNU 4164 F/C3 is a double row cylindrical roller bearing built to carry heavy radial loads at considerable speeds. Its two rows of rollers and machined steel cage support demanding industrial duty. Typical installations include gearboxes, rolling mills and machine tools, where precision and load capacity matter. MR Industrial Accessories LLC supplies this bearing to customers across the United States and in several Latin American countries.
Reading the designation helps you confirm the bearing before you order. The NNU prefix identifies a double row cylindrical roller bearing with a flangeless inner ring and a flanged outer ring. The 4164 block defines the size and dimensional series. The F suffix denotes a machined steel cage, while C3 calls out radial internal clearance greater than normal. Checking these codes against your equipment records is the quickest way to verify a replacement.
These bearings appear in steel, cement, mining and paper operations. You will find them in large gearboxes, rolling mill trains, crushing mills and extraction machines. Their rigidity and radial load capacity suit assemblies that require high precision and reliable running. MR Industrial Accessories LLC serves these sectors from its Miami base.
Selection starts with the radial load and speed conditions of the application. A C3 clearance is often chosen when temperature differences between the inner and outer rings are expected, since the running clearance changes as the bearing warms. Lubrication follows temperature and speed: grease or oil. During mounting, keep the seat clean and align the components precisely. Verify radial clearance before start-up, and confirm the F cage is compatible with the lubrication method you plan to use.
For equivalents, double row cylindrical roller bearings follow international standards, so dimensions and clearance can be matched across manufacturers. When sourcing a replacement, compare series, size and suffixes, because cage and clearance letters are not always the same from one maker to another. Send us the original code and our team can suggest an equivalent.

Frequently asked questions
- What does the C3 suffix mean on an SKF bearing?
- C3 indicates radial internal clearance greater than normal. It is specified when operating conditions create temperature differences between the rings, which alters clearance during running. The greater clearance compensates for those variations and helps prevent excessive preload.
- How do I choose between a single row and a double row bearing?
- It depends on the radial load and the rigidity required. Double row bearings handle higher radial loads and provide greater rigidity, but take up more axial space. Single row bearings suit moderate loads and allow higher speed. Review the available space and load conditions.
- Can I replace an NNU bearing with one from a different brand?
- Yes, provided the main dimensions, internal clearance and cage type are equivalent. International standards support interchangeability, but check each manufacturer's suffixes, as they may differ. Send us the original code and we will help you find a suitable alternative.
