These four types of bearings play a crucial role in a wide range of machines and equipment, providing support for rotational and linear motion, reducing friction, and enabling the efficient and reliable operation of various mechanical systems across industries.

   - Radial ball bearings are designed to support radial loads, which are forces acting perpendicular to the shaft's axis. They are commonly used in applications where the primary load is radial, such as in electric motors, pumps, and gearboxes.
