Tapered roller bearings are separate bearings, and the inner and outer rings of the bearing have tapered raceways. This type of bearing is divided into different structural types such as single row, double row and four row tapered roller bearings according to the number of rows of rollers installed. Single row tapered roller bearings can withstand radial loads and axial loads in a single direction. When the bearing is subjected to a radial load, an axial component will be generated, so that another bearing that can withstand the axial force in the opposite direction is needed to balance.
A tapered roller bearing is a radial thrust type rolling bearing 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 radial and axial combined loads mainly based on radial load. It is often used in double and reverse installation. 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 is mainly subjected to axial and radial combined loads mainly based on axial loads. Generally, it is not used alone to withstand pure axial loads. When paired configuration (relatively installed at the same name), it can be used to withstand pure radial loads.
