Tapered roller bearings are mainly subjected to combined radial and axial loads based on the radial direction. The bearing capacity depends on the raceway angle of the outer ring, the larger the angle, the greater the bearing capacity. 

This type of bearing is a separable bearing, which is divided into single-row, double-row and four-row tapered roller bearings according to the number of rows of rolling elements in the bearing.

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