Ball transfer conveyors consist of ball transfers that are attached to rigid frames or plates. They allow flat-bottomed loads to roll along a path from one place to another, reducing the effort it takes to move the loads in warehousing, package handling, manufacturing, and distribution applications. Ball transfers (sometimes known as ball transfer bearings) let loads move in all directions on the conveyors, so these conveyors are typically installed at the start and end of conveyor systems, at points along a conveyor system where loads need to change direction or move to an adjacent conveyor line, and at packing tables or workstations where loads need to be rotated or positioned. Replacement ball transfers and other ball transfer conveyor components can be used to repair the conveyors or improve their performance.
