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.

The primary difference between a thrust ball bearing and a radial ball bearing lies in their design and the direction of the loads they are designed to support:

   - Cylindrical Roller Bearings: Cylindrical roller bearings consist of cylindrical rollers held in place by inner and outer rings, with the rollers positioned parallel to the axis of the bearing. They are designed to primarily support radial loads and provide high rigidity and precision.
