... Variations in bearing geometry (oil grooves, edges of oil hole) often are responsible for flow instability. When oil flow goes from a grooved region to an ungrooved section, an area of low-pressure oil is created at the end of drilling. Vapor bubbles can be formed in this region and their collapse can cause...
