The NTN RNA49 series needle roller bearing is a radial bearing without an inner ring, designed to withstand high radial loads in reduced spaces. It is used in applications where the shaft acts as a direct raceway, which allows a more compact and lighter design. It is a common solution in transmissions, pumps, compressors and agricultural machinery, where precision and load capacity are critical. MR Accesorios Industriales is an official distributor of NTN in Buenos Aires, Argentina.

The RNA49 series designation is interpreted as follows: RNA indicates a needle roller bearing without an inner ring; 49 is the dimension series, which defines the outside diameter and the width according to the shaft diameter. The suffix T2 indicates a reinforced polyamide cage, and the final T may refer to tolerance or heat treatment variants. For example, the code RNA496T2T combines these elements and translates into a bearing for shafts of approximately 10 mm bore diameter, with an outside diameter of 19 mm and a width of 12 mm, although it is always advisable to confirm the exact measurements with the drawing or direct measurement.

In Argentine industry, RNA49 series needle roller bearings are found in gearboxes, hydraulic pumps, air compressors, harvester machines and material handling equipment. Their ability to withstand high radial loads in a minimal space makes them ideal for applications where the shaft diameter is limited and rigidity is required. They are also used in electric motors, reducers and linear guide systems, where precision and durability are key factors to avoid unscheduled downtime.

To correctly select an RNA49 bearing, take into account the hardness and surface finish of the shaft, which acts as the inner raceway. The surface must have a minimum hardness of 58 HRC and adequate roughness to guarantee service life. Mounting requires precise alignment and adequate lubrication, whether grease or oil, depending on the speed and operating temperature. If the environment has contaminants, evaluate the incorporation of external seals. The T2 polyamide cage offers good fatigue resistance and low friction losses.

NTN RNA49 series needle roller bearings are interchangeable with those of other brands that follow the same dimensional designation, such as SKF, FAG or NSK, as long as the outside diameter, width and shaft diameter measurements match. However, tolerances and cage materials may vary between manufacturers, so it is advisable to verify the exact equivalent before replacing. If you have the code of another brand, at MR Accesorios Industriales we will indicate the equivalent NTN reference.
