Definition of the word caster

The word "caster" originally referred to a person or animal that pulled a cart or wagon. This usage can be traced back to the Middle English word 'castern', which came from the Old French 'castere' meaning 'carter'. As time passed, the meaning of the term evolved to also refer to the wheel or set of wheels that allow a piece of equipment to be easily moved from one location to another. This usage is commonly seen in furniture items such as swivel chairs, tables, and rolling carts. In factories and warehouses, casters are used on industrial equipment such as machinery, lift trucks, and carts, making it easier to move heavy objects without causing damage to surfaces. The technical definition of a caster is a wheel, usually made of polyurethane or nylon, mounted on a swivel bearing that allows it to turn easily. The size, material, and wheel type can all affect the way a caster performs. In summary, the word "caster" has its roots in the traditional sense of someone or something that pulls a cart, and has since evolved to describe thewheels or set of wheels that allow specific objects to be easily moved.
