.... Visual Examination of General Physical Features The ball bearings were both of the single-row, deep-groove type with split inner rings and a cage. The cage was made of aluminum bronze. The rings and balls were made of steel, equivalent to 52100 bearing steel. These bearings were mounted side by side...

... friction is lower than sliding friction. The most important device that allows rolling to occur are rolling element bearings, balls, and rollers—they move the world. Our vehicles move on roller wheel bearings; high speed motors employ ball bearings; aircraft engines require rolling element bearings...
