(1) Tapered roller bearings are separable bearings. The inner and outer rings of the bearings have tapered raceways. This type of bearing is divided into 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 bear radial load and single direction axial load. When the bearing bears radial load, an axial force component will be generated, so another bearing that can bear the axial force in the opposite direction is required for balance.

(2) Tapered roller bearings are widely used in automobile, rolling mill, mining, metallurgy, plastic machinery and other industries.
