Brief History of Steel Balls
The history of steel balls may be traced as far back as ancient Egypt. Early drawings suggest that the massive stones used to construct pyramids were moved using a method that involved rolling balls.
Other depictions indicate that hand drills were crafted using a type of ball bearing mechanism.
An actual wooden ball bearing used in a rotating table was found in the wreckage of a circa 40 AD Roman ship, recovered from Lake Nemi in Italy.
Around 1500, Leonardo da Vinci created his design for a helicopter, which included drawings of ball bearings.
A century later, Galileo conceptualized caged balls in a ball bearing application. It was not until nearly two hundred years later, in Wales, that the first ball bearing design was patented by an inventor named.
