Spherical roller bearings are essential components in a wide range of industries due to their versatility and ability to support heavy loads in various applications. These bearings are commonly found in machinery used in mining, construction, automotive, and aerospace industries, among others. They are specifically designed to accommodate high radial and axial loads while being able to operate in harsh and demanding conditions. The construction of the bearing NU 208 involves high-quality steel, ensuring durability and resistance to wear. It is also often equipped with a cage made from brass or polyamide, which helps to maintain the separation of the rolling elements, enhancing the bearing's performance and lifespan. 3. **Roller Assembly** The roller assembly is the heart of the tapered roller bearing. It includes the tapered rollers and the cage (or retainer). The rollers, shaped like truncated cones, distribute the load evenly across their length, reducing stress points and enhancing bearing life. The cage keeps the rollers separated and in place during rotation The cage keeps the rollers separated and in place during rotation
