Tapered roller bearings are separated bearings, and the inner and outer rings of the bearings have tapered raceways. This kind of bearing is divided into single row, double row and four row tapered roller bearing and other different structural types 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 when another bearing that can bear the axial force in the opposite direction is needed to balance.
Tapered roller bearing refers to the radial thrust type rolling bearing whose rolling body is a tapered roller. There are small cone angles and large cone angles. The small cone Angle is mainly subjected to radial load and radial axial load, often into double use, reverse installation, the inner and outer seat ring can be installed respectively, in the installation and use can adjust the radial and axial clearance; The large cone Angle is mainly used to bear axial load and radial load. Generally, it is not used to bear pure axial load alone, but can be used to bear pure radial load when it is configured (relative installation of the same name end).
