Ceramic ball bearings are the end result of a long evolution which probably started many thousands of years ago and this use of ceramic material has many benefits to offer the manufacturing industry.
Right from the very earliest days of man, round rollers were utilized to move heavy objects. It seems likely that our present day system of ball bearings has evolved from the logs that early humans used as primitive rollers, to move objects that were too heavy to be dragged along the ground. And every schoolchild has seen the pictures that show the ancient Egyptians using logs as rollers for the giant stone blocks that were used to build the pyramids. At some point in the distant past the idea of fixing the roller to the object being moved was born and this led to a primitive vehicle with the first 'wheels'.
