Tapered roller bearings are separable bearings. Both 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 installed. Single row tapered roller bearings can bear radial load and single direction axial load. When the bearing bears radial load, it will get an axial component force, so when it needs another bearing that can bear the axial force in the opposite direction to balance it. Tapered roller bearings means radial thrust rolling bearings with tapered rollers. There are two types: small cone angle and large cone angle. The small cone angle mainly bears the combined radial and axial load, which is mainly the radial load. It is often used in pairs, opposite installation, the inner and outer races can be installed separately, and the radial and axial clearance can be adjusted during installation and use; The large taper angle mainly bears the combined axial and radial load based on the axial load. Generally, it is not used to bear the pure axial load alone, but can be used to bear the radial load, When configured in pairs, it can be used to withstand radial loads.
