For applications that demand high radial load capacity and speed, the SKF RN series cylindrical roller bearing provides a proven solution. This single-row bearing uses cylindrical rollers and a steel cage to maintain precise operation in gearboxes, pumps, machine tools, and power transmission equipment. MR supplies this line with technical guidance to help you specify the correct execution for your equipment.

Reading an SKF RN part number is straightforward when you know the suffixes. The letters RN identify a single-row cylindrical roller bearing with special dimensions. The suffix B points to a machined brass cage, while G refers to specific internal manufacturing characteristics. For example, a part number such as RN-3X9.8 B/G2 combines these designations with particular dimensions. Including the full part number when requesting a quote avoids confusion and ensures you get the exact replacement.

Typical installations include gearboxes, centrifugal pumps, compressors, machine tools, and transmission systems. These bearings also suit equipment that needs high radial rigidity, such as rolling mills. Because the design is separable, maintenance teams can remove and replace components more easily. MR works with customers across the United States, Canada, Mexico, and South America, supplying bearings for these and similar sectors.

To specify the right bearing, evaluate the radial load, operating speed, and lubrication method. The RN series is usually mounted with an interference fit on the inner or outer ring, depending on the load path. Check housing alignment and sealing to keep contaminants out. Grease or oil lubrication should follow the manufacturer's recommendations. Using proper mounting tools helps protect the rollers and cage during installation.

SKF cylindrical roller bearings can be interchanged with other brands that match the same dimensions and tolerances. However, suffixes and internal executions are not always identical between manufacturers. When comparing equivalents, verify the full part number, dimensions, and cage type. If you are unsure, send the original part number to MR and we will help identify a suitable option. Interchangeability depends on more than just size.
