A study of outbreak limit electric current density of electrical pitting for small ball bearings

Abstract

A lot of problems by electric pitting of small ball bearings have come to be shown in recent years. A lot of research on electric pitting of bearings for railroad vehicles have been done, but there is little research for the small ball bearings. This is a basic experiment of electric pitting for small ball bearings (608,6201) and this research showed that electric pitting occurred below the measure of current density of electric pitting generated by past research.
