Basic Concepts of Hub Bearings
Understanding the basic principles behind hub bearings enhances their maintenance and repair:
-
Axial and Radial Loads: Hub bearings manage both axial (up and down) and radial (side-to-side) forces.
-
Preload: Bearings are typically preloaded to a specific torque to ensure optimal performance and reduce noise.
-
Lubrication: Hub bearings rely on proper lubrication to minimize friction and wear.
-
Sensors: Some bearings integrate sensors that monitor wheel speed, providing data for anti-lock braking systems and other safety features.
