TRB is separated bearing, and the inner and outer circles of the bearings have tapered rollers. This type of bearing is divided into different structural types such as single-row, dual -row and four-row, according to the number of rollers installed.

There are two types of cone angle and large cone angle. The small cone angle is mainly tolerated by radial and axial loads mainly based on radial loads. It is often used in dual use and reverse installation. The inner and outer seats can be installed separately. The large cone angle is mainly tolerance for axial and radial combination loads mainly based on axial loads. Generally, it is generally not used to withstand pure axial loads as a pair configuration.

TRB is widely used in industries such as cars, rolling machines, mines, metallurgy, plastic machinery.
