Tapered roller bearings are separate bearings, and the inner and outer rings of the bearing have tapered raceways. This type of bearing is divided into different structural types such as single row, double row and four row tapered roller bearings according to the number of rows of rollers installed. Single row tapered roller bearings can withstand radial loads and axial loads in a single direction. When the bearing is subjected to a radial load, an axial component will be generated, so another bearing that can withstand the axial force in the opposite direction is needed to balance.

Tapered roller bearings are usually of a separate type, that is, a conical inner ring assembly consisting of an inner ring with a roller and a cage assembly can be mounted separately from the outer bevel (outer ring). Tapered roller bearings are widely used in automobiles, rolling mills, mining, metallurgy, plastic machinery and other industries.
