- Thrust bearings, on the other hand, are designed to support axial loads within the engine or machinery. In an engine, thrust bearings are typically located at the end of the crankshaft to counteract the axial forces generated by the engine's operation. They are responsible for maintaining the axial position of the crankshaft and preventing it from moving forward or backward.

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.
