Excessive load pressures on a bearing typically result in what condition?

Excessive load pressures on a bearing typically lead to spalling, which is a phenomenon characterized by the flaking or pitting of the bearing material. This condition occurs when the stresses imposed on the bearing exceed its capacity to sustain that load, leading to fatigue in the material. As the bearing operates under these excessive loads, small pieces of the surface material break away, resulting in surface damage known as spalling. This not only compromises the integrity of the bearing but also affects its performance, as the contact surface becomes rougher and less effective at supporting loads.

While overheating, deformation, and corrosion can also occur under different circumstances, spalling specifically addresses the mechanical failure aspect tied directly to excessive load pressures. Understanding the implications of load on bearings is crucial for ensuring their longevity and reliability in any application.
