- 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.

   - They have raceways that are parallel to the bearing axis, allowing them to effectively support radial loads and provide smooth and efficient rotation of shafts and components.

The angle of contact in angular contact ball bearings is a critical design parameter that influences the bearing's load-carrying capacity, precision, rigidity, and high-speed capability. It allows the bearing to operate efficiently under dynamic and oscillating loads, making it suitable for applications where precise motion control and accurate load distribution are essential.
