Tapered roller bearings refer to radial thrust rolling bearings with tapered rollers. There are small cone angles and large cone angles. The small cone Angle is mainly subjected to combined radial and axial loads with radial load as the main part. It is often used in pairs and installed in reverse. The inner and outer seat rings can be installed separately. The large cone Angle is mainly used to bear the combined axial and radial load, which is mainly axial load. It is generally not used to bear the pure axial load alone, but can be used to bear the pure radial load when it is configured (the end of the same name is installed relatively).

The ability of a single row tapered roller bearing to bear axial load depends on the contact Angle, that is, the raceway Angle of the outer ring. The larger the Angle, the greater the axial load capacity. Tapered roller bearings in the largest amount of single row tapered roller bearings. In the front wheel hub of the car, a small size double row tapered roller bearing is used. Four-row tapered roller bearings are used in heavy machines such as large cold and hot rolling mills. What are the relevant parameters of tapered roller bearings?
