The SKF RN series cylindrical roller bearing is a component designed to withstand high radial loads and high speeds. Its construction with cylindrical rollers and steel cage allows precise operation in demanding industrial applications. It is used in gearboxes, pumps, machine tools and power transmission equipment. MR Accesorios Industriales sells this line, with technical advice to select the right execution for your equipment.
The RN series designation is interpreted by its letters and suffixes. In SKF part numbers, RN identifies single row cylindrical roller bearings with special dimensions. The suffix B indicates a machined brass cage execution, and G indicates specific internal manufacturing characteristics. For example, the part number RN-3X9.8 B/G2 combines these letters with particular dimensions. Knowing these suffixes allows you to order the exact replacement without confusion.
In Argentine industry, these bearings are used in gearboxes and gear cases, centrifugal pumps, compressors, machine tools and transmission equipment. They also appear in applications requiring high radial load capacity and rigidity, such as rolling mills or mills. Being separable, they facilitate maintenance and parts replacement. MR Accesorios Industriales has extensive experience supplying bearings for these sectors.
To select the correct bearing, take into account the radial load, rotation speed and type of lubrication. The RN series is usually mounted with an interference fit on the inner or outer ring depending on the case. Check the alignment of the housings and the sealing to prevent contamination. Lubrication can be grease or oil; follow the manufacturer's recommendations. Mounting with the right tools extends the service life of the bearing.
SKF cylindrical roller bearings are interchangeable with those of other brands that follow the same dimensions and tolerances. When looking for equivalents, compare the full part number, the dimensions and the cage type. Not all suffixes match between manufacturers. If you have doubts, send us the original part number and we will help you identify the right option. Interchangeability depends on the internal execution, not only on the size.
