Rigid casters are wheels that are fixed in one direction, allowing for straight-line movement. They do not swivel, which means they provide stability and support for heavy loads. Rigid casters are commonly used in applications where precise control and stability are essential, such as in industrial carts and warehouse equipment. These casters are typically mounted on a plate or stem, making them easy to attach to various surfaces. They are available in different materials, such as rubber or polyurethane, to suit different floor types and weight capacities. Rigid casters are ideal for moving items in a straight path without the need for frequent directional changes.
