The RNA49/28 RICH is a needle roller bearing without an inner ring, designed for applications where space is limited and high radial load capacity is essential. By eliminating the inner ring, this bearing allows the shaft itself to serve as the inner raceway, which significantly reduces the overall radial cross-section. This design requires the shaft to be hardened and ground to the appropriate specifications for optimal performance. Equipped with a durable steel cage, this bearing ensures precise roller guidance and is engineered to handle heavy loads with exceptional rigidity, making it an excellent choice for a wide range of industrial and automotive machinery.
