Star Ball Transfer Units are referred to as ball transfer table units that carry a large load-bearing ball that sits atop smaller balls inside of a hemispherical cup. These are used in applications that require manual rotation or positioning, as they facilitate the quick and easy handling of products and materials. These units have sports springs to absorb momentary shock loads from these conveyor line transfers. Star Ball Transfer Units are made of carbon steel, stainless steel and nylon. It is commonly used steel that contains carbon as its main ingredient.
