Tapered roller bearings are used in back-to-back pairs so that axial forces can be supported equally in either direction. Pairs of tapered roller bearings are used in car and vehicle wheel bearings where they must cope simultaneously with large vertical (radial) and horizontal (axial) forces. Applications for tapered roller bearings are commonly used for moderate speed, heavy duty applications where durability is required. Common real world applications are in agriculture, construction and mining[...]

Deep groove ball bearings mainly take radial load as well as take moderate axial load. With less coefficient of friction , high limiting speed, large size range and variations of structure, they are suitable for precision instruments, low noise motor, Automobile ,Motorcycles, and other common machinery, as a widely used type of bearings in machinery industry.[...]
