The NSK RNAFW series needle roller bearing is a radial needle roller bearing without an inner ring, designed for applications where radial space is limited and high load capacity is required. It mounts directly onto a hardened and ground shaft, which simplifies the design and reduces the weight of the assembly. It is a common solution in transmissions, pumps, compressors and continuous production machinery, where robustness and dimensional precision are key to performance.

The RNAFW series designation reads as a size code: the figures that follow the letters indicate key bearing dimensions. For example, RNAFW142220 corresponds to a bearing with an outside diameter of 22 mm and a width of 20 mm, while RNAFW203224 has a 32 mm outside diameter and a 24 mm width. These numbers make it possible to quickly identify the size and select the right replacement without measuring the part. The RNAFW series is characterized by its construction without an inner ring, with a steel cage and guided needles.

In Argentine industry, NSK RNAFW series needle roller bearings are used in a wide variety of equipment: from machine tools and presses to conveyors, water pumps and air compressors. They are also found in the automotive sector, in gearboxes and steering systems, as well as in agricultural machinery, where demanding working conditions require durable and reliable components. Their compact design makes them ideal for confined spaces, allowing the size of housings to be reduced without sacrificing load capacity.

To correctly select an RNAFW bearing, take into account the shaft diameter and hardness: it must be hardened and ground, with a surface hardness suitable for supporting the loads of the needles. Lubrication is essential: grease or oil can be applied, and in many cases the bearing already comes lubricated from the factory. Check the alignment between the shaft and the housing to avoid parasitic axial loads and premature wear. Sealing will depend on the environment: in contaminated environments, consider additional protections such as radial shaft seals or covers.

When replacing a needle roller bearing, it is common to find equivalences between different brands. Although each manufacturer has its own nomenclatures, standardized dimensions allow bearings with similar characteristics to be interchanged. If you have the code from another brand, you can ask us and we will tell you the equivalent NSK reference. At MR Accesorios Industriales we sell the NSK brand and advise you so that you find the right bearing for your application, whether you need a single unit or a batch for maintenance.
