Tapered roller bearings belong to separation bearings, bearing inner and outer rings have tapered raceway. The bearings can be divided into single row, double row and four row tapered roller bearings according to the number of roller rows. Single row tapered roller bearings can withstand radial load and single direction axial load. When the bearing bears radial load, there will be an axial component, so another bearing that can withstand the axial force in the opposite direction is needed to balance it.
