A customer experienced failures in a silicon saw application. As a result of the facility clean environment requirements, lubrication was being washed out of the bearings and silicon particles were entering the raceways causing bearings failures to occur. Bearing failures were occurring on 4 separate machines utilizing a total of 384 bearings per year. NSK proposed to replace the bearings with Deep Groove Ball Bearings using Molded-Oil lubrication.
