Moving Materials in Manufacturing

The invention of the wheel early in man’s history has resulted in many ways to reduce manual labor. Among these helpful applications are the automotive industry, bearings for rotating machinery and other time and energy-saving technologies. The use of wheels in manufacturing often includes the movement of materials from one location to another. Many factory floors require that heavy materials be regularly relocated for the stages of assembly or machining processes. The use of a crane is necessary for some of the instances. Others make use of carts set on heavy duty casters allowing equipment to be relocated by simply rolling it from one station to another. A caster makes use of the wheel in two different ways. Both applications overcome friction and allow for heavy loads to be moved with little energy. These two applications are the caster wheels themselves and the bearings inside each caster.
