The use of ball bearings is common in many industrial and commercial settings. These bearings allow for smooth movement of parts or whole pieces of equipment and without these components one would be replacing parts often that were worn because of friction. Ball bearing manufacturers make parts that consist of inner and outer rings, inner and outer raceways, balls and a ball cage. The inner and outer raceways are the areas or tracks that the balls follow. The inner raceway is located on the surface of the inner ring and the outer raceway is located on the surface of the outer ring. The raceways provide a smooth track and unstopped motion for the balls.
