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.

Plain Bearings: Also known as bushings or sleeve bearings, plain bearings consist of a simple cylindrical design without rolling elements. They rely on a sliding motion to reduce friction and are often used in low-speed, high-load applications such as in agricultural machinery, construction equipment, and industrial machinery. Plain bearings are valued for their ability to handle heavy loads and operate in harsh environments.
