Defining Caster
Let''s begin by understanding the term "caster." Caster is a noun that refers to a small wheel or a set of wheels attached to the bottom of furniture, equipment, or other objects, allowing them to move easily in any direction. These wheels are typically designed to rotate freely and are often found on chairs, tables, carts, and other movable objects.
Casters are commonly made of metal or plastic and are available in various sizes and designs to suit different applications. They are generally mounted on a swivel, making it possible to move the object by simply pushing or pulling it in the desired direction. As a result, furniture with casters can be easily repositioned to accommodate changes in room layout or to improve mobility.

Now, let''s turn our attention to the term "castor." Castor is also a noun, but it has a different meaning altogether. Castor refers to an oily substance that is derived from the castor bean, scientifically known as Ricinus communis.

The castor oil obtained from these beans has various industrial, medicinal, and cosmetic uses. It is commonly used as a lubricant in engines, as a component in certain paints and varnishes, and as an ingredient in some pharmaceutical products.
