In a Ball Mill Motor Bearing, where does Lead (Pb) come from as shown in the oil analysis data and what does it indicate?

Lead can be present in the bearing material( composition of bearing) thus if you suffer some touchdowns or the bearing is not fully floating on oil you will get traces in the sample. Look for scuff marks on the bearings( hard without jacking it up off them) or the trunnions.
