Does residual stress affect quality? The short answer is “yes.” The better question is, “How does residual stress affect quality?”

As one of the most common mechanical components in the world, roller elements are of critical importance. It is necessary for bearings and raceways to be carefully engineered and manufactured so that the machines which use them are as safe and stable as possible.

The push for increased fuel efficiencies has pushed the aerospace industry to develop stronger and lighter materials while simultaneously increasing component longevity. In turn, these new designs, materials, and processes require verification.
