The NTN RNA49 series is a radial needle roller bearing that operates without an inner ring. This design lets the shaft serve as the raceway, which saves space and reduces weight. It is a common choice for transmissions, pumps, compressors and agricultural equipment where radial loads are high and the envelope is tight. MR Industrial Accessories supplies this series to customers across the United States and Latin America.

Reading the code helps you confirm what you are ordering. RNA means the bearing has no inner ring. The 49 is the dimension series, which sets the outside diameter and width in relation to the shaft. A suffix such as T2 points to a reinforced polyamide cage, and a final T can indicate a tolerance or heat treatment variant. For instance, RNA496T2T describes a bearing for a shaft of about 10 mm, with an outside diameter of 19 mm and a width of 12 mm. Always confirm the exact figures against a drawing or by measuring the old part.

These bearings show up in gearboxes, hydraulic pumps, air compressors, harvesters and material handling systems. Because they handle high radial loads in a small space, they suit setups where the shaft diameter is limited but rigidity is still needed. You will also find them in electric motors, reducers and linear guide systems, where precision and long service intervals matter.

Selection starts with the shaft, since it acts as the inner raceway. The surface should reach a minimum hardness of 58 HRC and have a suitable finish to support service life. Mounting calls for precise alignment and proper lubrication, grease or oil, based on speed and operating temperature. In dirty environments, consider external seals. The T2 polyamide cage provides good fatigue resistance and low friction losses.

NTN RNA49 bearings can be replaced by other brands that use the same dimensional designation, such as SKF, FAG or NSK, provided the outside diameter, width and shaft diameter match. Tolerances and cage materials can differ between makers, so check the exact equivalent before installing. If you have another brand's code, we can point you to the NTN reference.
