- 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.

According to the researchers, the new bearings are designed to withstand extreme temperatures, high loads, and corrosive environments, while also offering reduced friction and improved efficiency. The technology could be particularly useful in the aerospace, automotive, and industrial sector, where bearings are critical components in many manufacturing processes.

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.

   - Needle Roller Bearings: Needle roller bearings feature cylindrical rollers with a much smaller diameter-to-length ratio compared to cylindrical rollers. This design allows for a higher load-carrying capacity in a compact space, making needle roller bearings suitable for applications with limited radial space.

   - Ball Bearing: Ball bearings are primarily designed to support radial loads, with some variations capable of handling light axial loads. They are widely used in applications where smooth and efficient rotation is essential, such as in machinery, equipment, and automotive components.
