A Ball Transfer Units is a type of mechanical device used for conveying or transferring heavy loads or objects with minimal effort. It consists of a large number of small balls, usually made of steel or other durable materials, arranged in a circular pattern within a housing or frame. These balls are designed to roll freely in any direction, allowing for easy movement of objects in all directions. Ball Transfer Units are commonly used in material handling and conveyor systems, where they provide a smooth and low-friction surface for moving heavy objects, such as pallets, boxes, or machinery, with minimal manual effort. They are typically installed in a recessed or surface-mounted housing or frame, and can be used in various orientations, such as horizontal, vertical, or angled, depending on the specific application requirements.
