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.

These four basic parts work together to enable the tapered roller bearing to support radial and axial loads, provide precise motion control, and withstand the demands of various applications.
