      Tapered roller bearings are designed to withstand a radial and thrust load, and can be found in Mechanics  hubs due to the amount of radial and thrust loads they can carry. ... The ratio of the loads depends on the angle of the axes between the roller and bearing. The greater the angle is the greater axial load can be supported.

Roller Bearings

Unlike ball bearings, roller bearings are designed with heavy loads in mind. These bearings are primarily based around a cylinder, meaning this bearing is able to distribute a load over a large area, carrying heavy weights. Also unlike ball bearings, roller bearings are not made to handle thrust loads.


Ball Bearings

In small amounts of weight, this extremely common bearing is able to handle both thrust and radial load, making it a popular bearing with engineers. When ball bearings are in motion their main job is to transfer the load from the outer raceway to the inner raceway. This allows for a smooth spin. Ball bearings are commonly used in small wheels and hard drives, as well as other everyday
