Surface texture - a bearing surface may look shiny as it wears because the peak material with short spatial wavelengths has been removed during the run-in period. Michigan Metrology

Why do some bearings look shiny with wear?

April 25, 2023

We tend to think of “new” surfaces as shiny and smooth, and “worn” surfaces as rough, dull, or uneven. But for a bearing surface, the opposite is often true: the

Visualizing “filtering” — an animation

April 18, 2023

Surface texture can be described as a spectrum of spatial wavelengths. “Filtering” is the process to isolate the wavelengths that matter for our application. But what does that really look
