  Tapered roller bearing

Tapered roller bearing belongs to separate type bearing. The inner and outer rings of the bearing 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 bearing can bear radial load and single direction axial load. When the bearing bears radial load, an axial component will be generated, so another bearing that can bear the opposite axial force is required to balance.
