SKF cylindrical roller bearings are components designed to withstand high radial loads and considerable speeds. Their construction with cylindrical rollers and a steel cage allows precise and durable operation in severe industrial applications. MR Accesorios Industriales supplies this line as an official brand, with more than 80 years of experience in the field. If you need to replace a worn bearing or select the right one for your equipment, our technical team advises you so you can choose the correct option for your application.

The designation NNU 4164 F/C3W33 is interpreted as follows: the prefix NNU indicates a double row cylindrical roller bearing, with two inner rings and a flangeless outer ring. The number 4164 defines the size and dimensional series. The suffix F indicates a high-strength machined steel cage. The combination C3 corresponds to a radial internal clearance greater than standard, and W33 indicates that the outer ring incorporates a groove and three lubrication holes. This nomenclature allows you to quickly identify the constructional characteristics.

These bearings are used in equipment that must withstand heavy radial loads and moderate to high speeds. In Argentine industry, they are common in gearboxes, rolling mills, pulp and paper machines, high-flow pumps, industrial fans and mining equipment. They also appear in machine tool spindles and heavy transport rollers. Their ability to align and withstand combined forces makes them suitable for environments with vibrations and variable temperatures.

To correctly select a cylindrical roller bearing, take into account the radial load, rotation speed and environmental conditions. The C3 internal clearance is recommended when there are thermal gradients between inner and outer rings, or when the fit is interference. Lubrication with grease or oil must be chosen according to speed and working temperature; the W33 groove facilitates relubrication. It is essential to verify alignment between housing and shaft, and to mount with the right tools so as not to damage the rollers or raceways.

Regarding equivalents, double row cylindrical roller bearings are manufactured under international standards that allow dimensional interchangeability between different brands. When looking for a replacement, always compare the main dimensions, cage type and internal clearance. A code with C3 is not equivalent to one without a suffix, and the presence of W33 can be critical if the original design requires lubrication through the outer ring. Contact us if you have doubts about interchangeability.
