Wheel Hub Bearings
The primary role of wheel hub bearings is to bear loads and offer precise guidance for hub rotation. They handle both axial and radial loads, making them crucial components. Traditional automotive wheel bearings typically consist of two sets of tapered roller bearings or ball bearings.Assembly, lubrication, sealing, and clearance adjustment of these bearings are conducted on the automobile production line.However, this structure poses challenges during assembly in car production plants, increases costs, and reduces reliability. Moreover, cars require cleaning, lubrication, and adjustment during maintenance at service points.

What are the types of loads on bearings?
Bearings support various load combinations, but most types of application loads can be categorized into the following four main groups:
- Radial Loads
- Axial Loads
- Preloads
- Centrifugal Loads
What is radial load in bearings?
Radial load in bearings refers to the force perpendicular to the axis of the shaft and parallel to the bearing radius.
What is axial load in bearings?
Axial load in bearings is the force acting along the axis of the shaft, sometimes referred to as thrust load. Axial loads distribute forces equally and uniformly to the rolling elements, transmitting them from the inner to the outer ring of the bearing.
