Tapered roller bearings refer to radial thrust rolling bearings in which the rolling elements are tapered rollers. There are two kinds of small cone angle and large cone angle. The small cone angle mainly bears the radial and axial combined loads mainly with radial loads. It is often used in pairs and installed in reverse.
The inner and outer races can be installed separately. The radial and axial clearance can be adjusted during installation and use The large cone angle mainly bears the axial and radial combined loads, which are mainly axial loads. Generally, it is not used to bear pure axial loads alone. When configured in pairs (installed with the same name opposite), it can bear pure radial loads.
