Tapered Roller Bearings are separable bearings with tapered raceways on both the inner and outer rings. These bearings are classified by the number of roller rows, including single-row, double-row, and four-row tapered roller bearings. Single-row tapered roller bearings can withstand radial loads and unidirectional axial loads. When a bearing is subjected to radial loads, an axial force component is generated, necessitating a second bearing capable of balancing the opposing axial force.

Tapered roller bearings are widely used in automobiles, rolling mills, mining, metallurgy, plastic machinery and other industries.
