In summary, the key difference between thrust ball bearings and radial ball bearings lies in the direction of the loads they are designed to support. Radial ball bearings primarily support radial loads, while thrust ball bearings are specifically designed to support axial loads. Each type of bearing is tailored to meet specific operational requirements and environmental conditions in diverse industrial applications.

   - Cylindrical Roller Bearings: Cylindrical roller bearings are used in applications where high radial load-carrying capacity, rigidity, and precision are essential, such as in machine tool spindles, electric motors, and industrial equipment.

The deep groove in a ball bearing is characterized by a raceway with a deep, concave profile that forms a continuous, circular track for the bearing's rolling elements, typically steel balls. This design feature allows the balls to move freely within the raceway, distributing the load evenly and minimizing friction during rotation. The deep groove also provides space for the lubricant, which helps to reduce wear and heat generation, ensuring the bearing's longevity and reliability.
