Conical roller bearings belong to separable bearings, and both the inner and outer rings of the bearing have conical 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 roller rows installed. Single row tapered roller bearings can withstand radial loads and unidirectional axial loads. When a bearing is subjected to radial load, an axial force component will be generated, so another bearing that can withstand the opposite axial force is needed to balance it.

Conical roller bearings refer to radial thrust rolling bearings with conical rollers as the rolling elements. There are two types: small cone angle and large cone angle. The small cone angle mainly bears the combined radial and axial loads, which are mainly radial loads. It is often used in pairs and installed in reverse. The inner and outer race rings can be installed separately, and the radial and axial clearances can be adjusted during installation and use; The large cone angle mainly bears axial and radial combined loads, mainly axial loads. It is generally not used alone to bear pure axial loads, but can be used to bear pure radial loads when configured as a pair (with the same end installed relative to each other).

The ability of a single row tapered roller bearing to withstand axial loads depends on the contact angle, which is the angle of the outer raceway. The larger the angle, the greater the axial load capacity. The most commonly used tapered roller bearing is the single row tapered roller bearing. In the front wheel hub of the sedan, small-sized double row tapered roller bearings are used. Four row tapered roller bearings are used in heavy machinery such as large cold and hot rolling mills.
