What is a consequence of a shock load on a bearing?

A shock load is a sudden and significant force applied to a bearing, often exceeding its designed load capacity. One of the primary consequences of such an impact is the potential for brinelling, which refers to the formation of small indentations or permanent deformations on the bearing surfaces. This occurs due to the high stresses experienced during the shock load, which exceed the material's yield strength, leading to localized deformation.

Brinelling can compromise the performance and longevity of the bearing. The indentations create irregularities in the raceways, leading to increased friction, higher operating temperatures, and ultimately, premature bearing failure.

Other possible outcomes of shock loads include loosening of components or potential lubrication issues, but these do not directly correlate to the mechanical deformation characterized by brinelling. Brinelling specifically identifies the material change due to excessive localized force, making it the correct choice in this context.
