Meet the RICH RNA 4909, the needle roller bearing that’s all about maximizing efficiency in tight spaces. With dimensions of 52x68x22 mm, it's designed without an inner ring, offering a smart solution when every millimeter counts.
Ingeniously using the shaft as a raceway, this design not only allows for a larger shaft diameter but also enhances rigidity. The steel cage ensures precise needle guidance and seamless rotation, contributing to a longer and more reliable bearing life.
Crafted with precision in China, the RNA 4909 RICH is an excellent choice for applications ranging from gearboxes and transmissions to agricultural machinery and compact industrial systems.
