Tapered roller bearing are able to freely roll across the mating surfaces of the shaft and hub preventing friction, heat, metal to metal grinding, and wear. The tapered bearings are held together typically by a an inner race that has a tapered surface for the bearings to roll against, and a flat inner radial surface to slide over a shaft.

The outer race is the opposite, with the inner surface being tapered, and the outer surface being flat. The tapered angle of the bearings allows the assembly to handle a radial AND an axial load. The axial load is often called a thrust load.

A typical example is a wheel hub bearing. The whee hub bearing is a tapered bearing to account for the two types of loads on the mating surface. The radial load comes from the weight of athe vehicle, the axial or thrust load is created by the helical gears of the differential, which tend to push on each other. This push creates a thrust load in the shaft, which is then transmitted to the angular surface of the tapered bearings by the tapered races.

Tapered roller bearings are made up of tapered inner and outer ring raceways, with tapered rollers placed between them in such a way that the roller’s surface converge at the bearing of the axis. These bearings can withstand the extreme level of loads in both directions, and this feature makes them unique and different from other types of bearings. Tapered roller bearings are designed in such a way that they can easily roll across the shaft and hub-mating surfaces, reducing friction, wear, metal to metal grinding heat.
