In mechanical terms, a bearing is a machine element that facilitates smooth and controlled motion between two or more moving parts. It is designed to reduce friction and support the load generated by the moving components, allowing them to move relative to each other with minimal resistance. Bearings are crucial in a wide range of machinery and equipment, providing support for rotational, linear, and oscillating motion.

   - 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.
