We have started finding white etching cracks in some of our high-speed bearings. What are the best approaches for diagnosing and mitigating this issue?
Check for overloading. Excessive loads often cause microstructural changes that lead to white etching cracks.
Use oil with anti-fatigue additives. It helps reduce the stress on bearing surfaces.
Inspect for shaft currents. Stray electrical discharges can cause surface damage leading to these cracks.
