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.

In summary, the angle of contact in angular contact ball bearings is a fundamental design feature that enables the bearing to support combined radial and axial loads, accommodate high-speed operation, and provide high precision and rigidity in various industrial applications.

The primary function of a bearing is to enable the controlled transfer of loads and motion while minimizing friction and wear. Bearings achieve this through the use of rolling elements, such as balls or rollers, or through sliding surfaces, depending on the specific type of bearing. By doing so, bearings help to maintain the integrity and alignment of rotating shafts, axles, and other mechanical components, ensuring smooth and efficient operation of the machinery.

   - Spherical Roller Bearings: Spherical roller bearings are designed to support heavy radial loads, as well as moderate axial loads, and are capable of accommodating misalignment. They are commonly used in applications where heavy radial loads, shock loads, and misalignment are present, such as in heavy machinery, mining equipment, and industrial applications.
