Ball Bearing Design and Application is written for the education of Mechanical Engineering and non Mechanical Engineering students alike. It is written in an easily understood style that is intended to bring to the reader the satisfaction of knowing the basic principles of the rotational motion that occur in every day products such as washing machines, manufacturing machines, automobiles, industrial equipment, and airplanes. Without anti-friction bearings, these products would be larger, heavier than and not nearly as efficient as they are today. Anti-friction bearings support the mechanism that cleans the clothes in a washing machine; they support the many shafts that are found in manufacturing machines and automobile transmissions; and they support the ever increasingly sized rotors in an airplane jet engine. They are called "anti-friction" because they operate in the high 90% efficiency range and therefore save countless amounts of energy in today's dynamic world.
