Casters are mechanical devices widely used in various equipment and furniture, typically made of rigid plastic or rubber. They are designed to provide convenient mobility on smooth surfaces, reducing friction for objects. Casters are commonly installed at the base of items such as furniture, office chairs, shopping carts, luggage, industrial equipment, and more, allowing them to glide effortlessly on the floor. Casters typically incorporate a rotating bearing that enables objects to pivot 360 degrees with minimal effort, making navigation and movement easier.
